CATDOLL : CATDOLL: Duckling hatching technology? Duckling raising technology in a nursery pot?

1. Duckling hatching technology?

1. Preparation before incubation

(1) Check the incubator and conduct a test run. Observe the operation of the motor, temperature/humidity controller, alarm, ventilation, egg turning and other systems. The test run time is 3 days.

(2) Calibrate the temperature inside the incubator. Use a human body thermometer to measure the temperature of the top, middle, bottom, front, back, left, right, inside and outside of the incubator. The temperature difference between the various parts of the incubator should be less than 0.2°C. If it is not, find the cause and wait until it is properly adjusted before incubating.

(3) Cleaning and disinfection. After each batch of chicks has hatched, the incubator, egg trays, and the inside and outside of the hatchery should be thoroughly cleaned, rinsed, and disinfected.

8. Watering and adding vinegar 9. Candling eggs 10. Transferring eggs to trays 11. Hatching eggs 12. Cleaning and disinfecting trays

1. Temperature and humidity: In the early stage of incubation (1-15 days), the temperature in the incubator should be controlled between 38.5°C and 38°C, and in the middle stage (16-30 days), it should be controlled between 38°C and 37.5°C. The humidity should be 60% in the early stage of incubation, 50% in the middle stage, and 60%-70% in the late stage and when hatching.

2. Turn the eggs: Turn the eggs more often, every 2.5 hours, at an angle of 180°, and turn the eggs manually twice a day.

3. Cooling eggs: You don’t need to cool the eggs in the early stage of incubation, but you can cool the eggs once a day in the middle stage and 3-4 times a day in the later stage.

4. Water spraying: From the middle of incubation to hatching, spray the eggs once with 35°C warm water when they are cooling down. After they are dried, put them into the machine to continue incubation.

5. Ventilation: The incubator should have an electric fan with ventilation holes to ensure uniform temperature and air circulation inside the machine. This is especially important in the middle and late stages of incubation. If necessary, slightly open the door.

6. Assisted production: The broiler ducklings will hatch after 35 days of incubation. Those with difficulty in hatching should be artificially broken to increase the hatching rate.

7. In spring, summer and autumn, you can also use solar hot water bag heat source electric incubator, which only costs 2 cents per day for every 1,000 eggs.

2. Seedling cultivation technology in seedling pots?

1. Prepare the nutrient pot: Before raising seedlings in the nutrient pot, you can first make the nutrient pot. The material for the pot wall can be dry straw or thin plastic. Surround the prepared materials into a cylinder. The nutrient pot does not need to be too large, and the diameter can be about 5 cm.

2. Filling the soil: There are no excessive requirements for the soil used for seedling cultivation. Ordinary breathable nutrient soil can be used, so that there is enough nutrition to supply the seedlings with. The soil should be disinfected and sterilized in advance. After the soil is prepared, fill the soil into the nutrient pot.

3. Sowing and seedling raising: After preparation, you can start sowing and seedling raising. Process the seeds well, then sow them evenly into the nutrient pots, cover them with a thin layer of soil, keep them moist, and promote the growth of seedlings.

3. Seedling tray seedling cultivation technology?

Because I like planting, I have bought plug trays online before and cultivated cherry tomatoes. In fact, the plug trays for peppers are not much different from it. It is recommended to choose a 53×27cm soft tray, with a single upper diameter of about 4cm, a lower bottom of 1.5cm, and a hole depth of about 4cm. The price is not very expensive, 1-2 yuan/piece, and 2-3 yuan/piece. The price is related to the thickness of the material. If you want to use it multiple times, you can buy something of better quality. For one-time seedling cultivation, you can choose a cheap one.

4. Weaning ducklings breeding technology?

The temperature for the first three days of brooding is 30-32 degrees. Starting from the fourth day, depending on the situation of the ducklings, the temperature can be adjusted down by 0.5-1 degree every day to ensure that the indoor temperature is around 20-22 degrees at the end of brooding. Since it is winter brooding, the indoor temperature depends on the temperature and the weaning time will be appropriately delayed.

As for temperature, the most important thing is to keep it stable. It should not fluctuate too high or too low. The temperature should be adjusted appropriately according to the performance of the ducklings.

Ducklings huddle together close to the heat source, with their down standing upright, their bodies curled up, and they often make sharp cries, indicating that the temperature is too low.

The ducklings are away from the heat source, panting with their mouths open, their back feathers are wet, their water intake increases, and their feed intake decreases, indicating that the temperature is too high.

5. Seedling cultivation technology?

Use high-quality substrate soil and add Youmeida seed fertilizer, mix well and put it into the seedling tray, and grow seedlings in the seedling shed. Keep a reasonable temperature and water content. Spray with meconium or transplanting spirit in time when the seedlings emerge to prevent damping-off disease. Spray with Bihu or Kangduole Jianai Pujiu or Aierjia two to three times during the seedling stage to enhance resistance to stress, promote root development, resist diseases, and cultivate strong seedlings. For reference

6. What are the technical methods for growing seedlings in seedling trays?

Choose a plastic black seedling tray, prepare the seedling matrix in it, and sterilize it. After soaking and germinating the seeds, you can sow them by mechanical sowing or manual sowing. Put one seed in each hole and place the seeds horizontally to avoid missing them. After sowing, cover the original matrix, remove the excess matrix with a scraper, and keep the surface flat.

7. Eggplant seedling tray cultivation technology?

1. Plug tray selection

Use a 288-hole tray for growing 2-leaf and 1-heart seedlings, a 128-hole tray for growing 4-5-leaf seedlings, and a 72-hole tray for growing 5-6-leaf seedlings.

2. Matrix Preparation

Use peat and vermiculite at a ratio of 2:1, or peat, vermiculite and waste mushroom material at a ratio of 1:1:1, and use vermiculite for covering. 288-hole trays have 2.8m3 of spare substrate per 1,000 trays, 128-hole trays have 3.7m3 per 1,000 trays, and 72-hole trays have 4.7m3 per 1,000 trays.

3. Fertilizer application

Mix the fertilizer and substrate evenly and set aside. After the seedlings have 3 leaves and 1 heart, spray the fertilizer on the leaves 2-3 times in combination with spraying water.

4. Planting seeds

The germination rate of seeds must be tested before sowing, and the germination rate of seeds used should be above 90%. Soak the seeds in nL of gibberellin for 24 hours, air-dry and sow or pelletize before sowing. The sowing depth of the hole plate should be greater than 1 cm, and the sowing depth of the 128-hole plate and 288-hole plate is 0.5-1.0 cm. After watering, each cell is clearly visible.

5. Moisture Management

After sowing and covering, spray the seedling tray with water to make the water holding capacity of the substrate reach more than 1%. When the cotyledons expand to 2 leaves and 1 heart, the water content is 70% to 75% of the maximum water holding capacity. When the seedlings are sold for sale with 3 leaves and 1 heart, the water content is 65% to 70% of the maximum water holding capacity.

6. Temperature management

The germination room is 25-300℃ during the day, which lasts for 4-5 days. When 60% of the seeds in the seedling tray are pushed up the soil, the seedling tray can be moved into the seedling greenhouse. After entering the greenhouse, the daytime temperature should be higher than 25℃, and the night temperature should be 18-20℃. When the night temperature of the greenhouse is low, geothermal wires and other temporary heating measures can be used. After 2 leaves and 1 heart, the night temperature can drop to about 15℃, but not lower than 12℃. Ventilate as appropriate during the day to reduce the relative humidity of the air.

7. Replanting and dividing seedlings

When eggplant is sown with precision, the germination rate is generally only 60% to 70%. Therefore, for seedlings that have grown in one go, the missing holes need to be filled when the first true leaf unfolds. Considering the workload of eggplant seedling filling, when using 72-hole trays to grow eggplant seedlings, most of them are first sown in 288 seedling trays, and when the seedlings grow to 1 to 2 true leaves, they are moved to 72-hole trays.

8. Seedling age and commercial seedling standards

For seedlings grown in 72-hole seedling trays, the plant height is 16-18 cm, the stem thickness is 4.0-4.5 mm, the area is 110 cm2, there are 6-7 true leaves and small flower buds, and the calendar age is 80-85 days. For seedlings grown in 128-hole seedling trays, the plant height is 8-10 cm, the stem thickness is 2.5-3.0 mm, there are 4-5 true leaves, the leaf area is 40-50 m2, and the calendar age is 70-75 days.

8. Leek sprout seedling tray cultivation technology?

1. Seedbed preparation

Leek seeds have poor soil-penetrating ability, so before sowing, the soil of the seedbed should be fertile and loose, not too hard, so that the seeds cannot break through the soil in time and cause seed death. Generally, sandy loam should be selected for the seedbed of leeks, so that it can be excessive during the seedling stage and can also ensure that the roots are less damaged when transplanting the seedlings.

2. Seed preparation

For leek piglets, try to choose new seeds with excellent varieties and strong adaptability. The sowing method can choose dry seed sowing or soaking seeds for germination. However, it should be noted that in hot weather, the seeds should be soaked for 8-10 hours and the water temperature should be maintained at 30-40 degrees. After soaking, the seeds need to be washed with water once a day to prevent the seeds from accumulating heat and deteriorating, affecting germination. Generally, they can be sown when they are white for 2-3 days.

3. Planting seeds

In order to prevent diseases when sowing, you can first coat or mix the seeds. After mixing the treated seeds and fine soil evenly, sprinkle them evenly on the seedbed, cover them with a layer of fine soil, press them down slightly with your hands, and water them thoroughly once. In order to keep warm and moist, you can cover them with straw or stalks to facilitate germination.

4. Build an arch shed

In order to ensure the safety of leek seedlings, especially in spring, the temperature is extremely unstable and there are many rainy days, which can easily cause damage to leek seedlings. Therefore, an arch shed can be built. The construction of the arch shed should be based on the planting area of ​​leek. When building, pay attention to leaving a sidewalk between the sheds for management.

5. Seedling management

After the seedlings have all emerged, it is necessary to strengthen the management of watering, fertilizing, and disease and pest control. Generally, watering can be done 7-10 days after the seedlings have all emerged, and pesticides can be sprayed 10-15 days after emergence to control diseases and pests. At the same time, attention should be paid to frost, root rot, and lodging.

9. How to grow sweet potato seedlings? What are the sweet potato seedling growing techniques?

1. Seed selection: Select healthy and complete sweet potatoes as seeds.

2. Process the seeds: Cut the sweet potatoes into pieces, making sure each piece has 3 to 4 eyes, then wrap them with a layer of wood ash and place them in a cool, ventilated place.

3. Soil: Prepare suitable soil, which should be loose, breathable, fertile and sandy.

4. Cultivation: Plant the sweet potato pieces in the soil, cover with a thin layer of soil, and water them with appropriate amount.

Sweet potatoes love light and are short-day crops. They require high light energy during their growth and are shade-intolerant crops. The longer the light energy is from the stem and leaf stage, the longer the growth period and the higher the photosynthetic efficiency. On the contrary, the photosynthetic efficiency will be reduced, affecting the growth of the plants.

10. What are the technical methods for growing pepper seedlings in seedling trays?

1. Selection of pepper seedling trays.

Because I like planting, I have bought plug trays online before and cultivated cherry tomatoes. In fact, the plug trays for peppers are not much different from it. It is recommended to choose a 53×27cm soft tray, with a single upper diameter of about 4cm, a lower bottom of 1.5cm, and a hole depth of about 4cm. The price is not very expensive, 1-2 yuan/piece, and 2-3 yuan/piece. The price is related to the thickness of the material. If you want to use it multiple times, you can buy something of better quality. For one-time seedling cultivation, you can choose a cheap one.

2. Breeding on a small scale using individual seedling trays.

The purchased plug tray should be sterilized in 80-degree boiling water. Do not use 100-degree boiling water. The plug tray is made of plastic and easily deformed by heat. The water temperature of 80 degrees is enough to kill most germs and keep the plug tray intact. After disinfection, add some humus, sawdust, etc., which need to be stirred evenly in advance. Add it to a height of about 0.6 cm from the hole of the plug tray. Use the small end of the chopsticks to poke a hole, put in the seeds, cover it, pour in a small amount of water, and put it in a warm place and wait for it to germinate slowly. Some planting friends will use the method of germinating with paper towels in advance and then put it in the plug tray. This is better. It can control the germination rate in the early stage of planting, which is also a good choice.

3. Plug trays are commonly used in large-scale seedling cultivation at nursery bases.

Nowadays, there are specialized people doing specialized tasks. For example, for seedling cultivation, there are specialized personnel at the seedling cultivation base to carry out the work. Mechanization is now very common. Semi-automatic mechanized operation has long been achieved for modern agricultural seedling cultivation, especially when using plug trays for seedling cultivation. Machines are now used, because the specifications of each plug tray are the same, so the advantages of machine operation are more obvious.

4. Things to note when growing seedlings in seedling trays.

Modern machine seedling trays have realized the operation of continuous water mats, and machines have replaced manual operations. Disinfection, filling of substrates, sowing, watering, hotbed cultivation and other processes can all be integrated, and only careful care is needed. For example, when raising seedlings, peppers need to be in a dark environment to germinate, which requires the use of black seedling trays, and even some small vermiculite to shade them to facilitate germination.

During the seedling raising period, the substrate humidity should be controlled. If you squeeze hard and squeeze out 2-3 drops of water, it is just right. If it is too dry, it will suddenly collapse when watered for the second time, which is not conducive to root growth. If it is too wet, it will cause root drowning, affect root breathing, and may also cause the seedlings to grow too long. In addition, pay attention to controlling the temperature. The temperature for pepper seedlings should be controlled at 22 degrees. It is also necessary to avoid planting too densely to avoid diseases and insect pests. When raising seedlings in hole trays, one seed is planted in one hole. When the seedlings grow to a certain height and the density increases, the seedlings should be picked in time, and transplanted or sold in time.
