1. How many kilograms of earthworms can be raised with one kilogram of cow dung?3 kg per square There are four key points in the breeding technology of earthworms raised with cow dung. The first is the feed formula. When feeding, 50% cow dung can be mixed with other feces to feed earthworms; the second is feed fermentation. Use straw and stalks to spread a layer of dry material with a thickness of about 10-15 cm for fermentation; the third point is feed modulation. After the feed is fermented, the pH value can be tested; the fourth point is breeding density. The number of earthworms raised with cow dung should be controlled within 10,000 per square meter. 1. Cow dung earthworm breeding technology 1. Feed formula: When feeding, use 50% cow dung, 50% pulp sludge, or 20% each of cow dung, pig dung, chicken dung, and 40% rice straw to feed the earthworms. Chicken manure must be used to raise maggots or left for more than 1 year before it can be used to raise earthworms, otherwise the earthworms will escape or die. 2. Feed fermentation: Use straw to spread a layer of dry material with a thickness of about 10-15 cm, and then spread 4 cm of manure on the dry material and repeat 3-5 layers. Use a watering can to spray water on each layer until the water seeps out. In high temperature weather, you can turn it over every 7 days. Generally, the feed fermentation work is completed after turning it over 3-5 times. 3. Feed preparation: After the feed is fermented, the pH value can be tested. The suitable pH value of earthworm feed is generally 6-7.5, but the pH value of many animal and plant wastes will be higher or lower than this value. If the pH exceeds 9, acetic acid, salt or citric acid can be used as a buffer. 4. Breeding density: The number of earthworms raised in cow dung should be controlled within 10,000 per square meter. The production earthworm population of 3 kg per square meter is about 20,000 to 31,000. In the early stage, the number of young earthworms can reach 30,000 per square meter, but in the later stage of breeding, it must be reduced to 20,000. 2. How many earthworms can one cubic meter of cow dung produce?For earthworm farming, one acre needs about 400 cubic meters of cow dung per year, and one cubic meter can produce about 2,000 kilograms of earthworms, with a market price of 4 or 5 yuan per kilogram. The gross income of one acre is 10,000 yuan, and six crops can be produced in one year, 4 crops in spring and summer, and 2 crops in autumn and winter. Cow dung turned over by earthworms will become earthworm manure, with a market price of more than 200 yuan per kilogram, which is mainly used in high-end flower and vegetable greenhouses. Earthworms are used for biological preparations, fish bait, medicinal value, etc., further extending the breeding model of planting and breeding, achieving the purpose of cow dung pollution control and waste resource recycling, thereby achieving good ecological, economic and social benefits. 3. How much breeding soil should be used for one pound of earthworms?1- Ground culture, feces do not need to be fermented, culture method, take 5 cm thick garden soil, cow dung cannot exceed 5 cm, cow dung 70% pig or chicken dung 30%, cannot exceed 2 cm. Density 1 square meter, earthworms 1 kg 2- Three-dimensional box breeding, no soil is needed, the manure must be fermented, the method is, cow manure 100%. Cow manure 50% straw 50%. Cow manure 70% pig or chicken manure 30%. Density 1 square meter, 25 cm, earthworms 5 kg 4. How many kilograms of cow dung does it take to feed one kilogram of earthworms?The ratio of fermented cow dung to soil is about 70%-80% loess. It is best to put it in a wooden box. After putting the earthworms, put a small piece of watermelon peel on the soil. Put it in a ventilated and cool place. The survival rate of the earthworms will be very high and the time will be very long. 5. How much cow dung is needed to produce one pound of adult earthworms?One pound of adult earthworms requires 20 pounds of cow dung. 6. How many earthworms can one ton of cow dung produce in how many days?To answer the question, if you want to ask how many days one ton of cow dung can produce how many earthworms, first of all, we say that one ton of cow dung can raise 60 to 70 kilograms of earthworms. The reproduction can double in 20 days. So one ton of cow dung can produce about 200 kilograms of earthworms per month. 7. What is the formula for cultivating earthworm seedlings?Take 5 cm thick garden soil, cow dung cannot exceed 5 cm, cow dung 70% pig or chicken dung 30%, no more than 2 cm. Density 1 square meter, earthworms 1 kg. 2. For breeding in three-dimensional boxes, no soil is needed, and the feces must be fermented. The method is 100% cow dung, 50% cow dung, 50% straw, 70% cow dung, and 30% pig or chicken manure, with a density of 1 square meter, 25 cm, and 5 kg of earthworms. 8. How much cow dung can be produced to produce 500 kilograms of earthworms?500 kilograms of earthworms can feed about 3.5-4.2 tons of cow dung. One ton of cow dung can raise 60 to 70 kilograms of earthworms. Cow dung is a good planting material for earthworms, but it must be fermented before use. Fermented and dried dung is not only breathable, but also will not burn the earthworms during fermentation. Before each feeding, spray with water to squeeze out excess water. Cow dung can be held into a ball and a small amount of water can be squeezed out. This is the best time to feed. 9. How much cow dung is needed to feed one acre of earthworms?For earthworm farming, one acre needs about 400 cubic meters of cow dung per year, and one cubic meter can produce about 2,000 kilograms of earthworms, with a market price of 4 or 5 yuan per kilogram. The gross income of one acre is 10,000 yuan, and six crops can be produced in one year, 4 crops in spring and summer, and 2 crops in autumn and winter. Cow dung turned over by earthworms will become earthworm manure, with a market price of more than 200 yuan per kilogram, which is mainly used in high-end flower and vegetable greenhouses. Earthworms are used for biological preparations, fish bait, medicinal value, etc., further extending the breeding model of planting and breeding, achieving the purpose of cow dung pollution control and waste resource recycling, thereby achieving good ecological, economic and social benefits. |
