Farmers' friends, today, tell you about the application of organic fertilizer on the vegetables of the shed。
The first is to limit the use of organic fertilizers with appropriate velocity fertilizers。
It is usually appropriate to use 5-7 tons of rotting chicken dung per acre per year or 6-8 tons of manure, such as pigs, cattle, etc., and to build more than an appropriate number of sheds, which should be properly reduced for more than five years. For wind sand, saline, white clay, black calcium, etc. With lower organic content, the black soil with higher organic content, and the grassland soil with less。
Secondly, organic fertilizers must be fully decomposed and the application of less than fully decomposed organic fertilizers is strictly prohibited。
Fresh manure, which contains bacteria and parasites and is not suitable for direct use, should normally be stacked and killed in the fermentation and decomposition processes of various pathogens, eggs and other bastard seeds. It can also gradually decompose organic matter from fertilizers into nutrients that plants can absorb。
Third, organic fertilisation is as diversified as possible。
The application of a single organic fertilizer is avoided for many years and some biofertilizers are applied in conjunction。
Four is fermentation using morbid biogas。
Methane fermentation is the result of the decomposition of various organisms, such as human and animal urine, crop straw, grass, agricultural waste, household sewage, etc., by a combination of microorganisms under conditions of isolation from air and a certain temperature, moisture, acid alkalinity, etc. Vegetable fields with no hazard use bio-fermentation fattening for sealing periods of more than 30d, high-temperature bio-fermentation temperatures of about 53°c continued at 2d, with no lumber in the faeces and no live maggot, thallium or new plume around the pool. The residues of biogas ponds may be used only after they have been disposed of in a non-hazardous manner。
Five is that there are many advantages in combining fertilizer with farmers。
Fertilizers are characterized by high nutrient content, high fertility and short duration. Single nutrients, farm fertilizer is complete and low nutrient content is slow and prolonged. So the two can be short。
