Crops, application of biogas slurry
First, the root of the general application of 667 square meters is 500-3000 kg. Fertilization time is good for sunny evenings. It is not suitable for fertilization when rainy or soil is too wet.
2. Cotton can be sprayed during the whole growth period of cotton. The concentration of spraying should be adjusted according to the different periods of cotton growth. The ratio of the pre-buddant biogas slurry to the clear water is 1:2, and the ratio after the bud is 1:1. Spray once every 7 days. After spraying, the cotton leaves are dark green, which can play the role of keeping flowers and keeping the bells and treating the cotton aphids and red spiders.
Third, leafy vegetables can be sprayed in any growing season, the ratio of biogas slurry to clean water is 1:1, sprayed once every 10 days. After spraying, the leaves are thick green, which can also play a role in controlling aphids and cabbage caterpillars.
4. Notes 1. The biogas slurry used must use the biogas slurry in the biogas tank with normal gas production for more than 1 month. The biogas slurry in the waste pond and dead pool cannot be used. It should be clarified when spraying, and filtered with gauze to prevent Block the sprayer. 2. The pH value of the soaked biogas slurry is between 6.8 and 7.5, otherwise it can not be soaked. 3.
