How to rett biogas rot phosphate fertilizer
Biogas residue contains 10% Mel 20% humic acid, which can increase the activity of humic acid and improve fertilizer efficiency by using ammonia or ammonium bicarbonate solution and acidic groups in the molecular structure of humic acid to form humic acid. The method of retting biogas humic acid fertilizer is to compost the biogas dregs extracted from the biogas digester with organic waste or soil, add a layer of waste (or soil) and a layer of biogas dregs 20 cm thick to form a large round platform-shaped fertilizer heap. Then cover the surface with some soil and pat it, and compost it for 15 days to form biogas fertilizer. If calcium, magnesium, phosphate fertilizer or phosphate rock powder is added to each cubic meter of biogas dregs during composting, it will become biogas rotten phosphate fertilizer. The fertilizer is suitable to be used as base fertilizer, with an application rate of 1000 kg per mu. According to the experiment of Beijing Academy of Agricultural Sciences, biogas rot phosphate fertilizer has a significant effect on increasing the yield of wheat, corn, eggplant and green pepper, with corn increasing by 13.8% and green pepper by 15%.

New Technology of Grain Pest Control
In rural areas, farmers often encounter such a phenomenon: when giving medicine, farmers do not know what pesticide they use, nor how many times the pesticide should be blended, but only know how many caps a bucket of water is mixed with (pesticide bottle cap). This is the true portrayal of most Chinese farmers using pesticides nowadays. Of course, this situation has something to do with farmers.

The key point is to apply phosphate fertilizer to rape at seedling stage.
Rape is a crop that needs more boron. Lack of boron at the seedling stage, the root system stops growing, there is no root hair or no lateral root, the growth point changes from brown to scorched and dies; timely application of boron fertilizer plays an important role in high yield and good quality of rape. The specific method is: boron fertilizer as base fertilizer is directly applied to the soil, which can be used in rape.
