Phosphate-mixed fertilizer method first mixes 3%-5% of superphosphate with soil and beef fertilizer, piles up for 10 to 15 days, and mixes with straw at a ratio of 1:2 to promote microbial activity. And the conversion of poorly soluble phosphorus can reduce the loss of nitrogen in the manure, and achieve the effect of increasing nitrogen, increasing phosphorus and greatly improving fertilizer efficiency. The manure accumulated in this way is applied two cubic meters per acre, and there is no need to apply phosphate fertilizer and nitrogen fertilizer in the middle.
The lime-staining method firstly mixes 100 kg of water and 3 kg of quicklime, and then 4 to 6 kg of lime water per 100 kg of straw, which is used to remove the wax on the surface of the straw, so that the straw is softened and crunchy, so that it absorbs water as soon as possible. Fermentation, not only shortens the time of tanning, but also improves fertilizer efficiency.
The manure and urine accumulating method firstly add the straw to the water for about 20 days to ferment it, and then add 20 to 30 kg of manure and excrement per 100 kg of straw, mix and evenly pile up the fermentation, which can increase the microbial activity and increase the compost. The organic matter content, and the nutrients easily lost in human excrement and urine are adsorbed to the organic matter of the straw, thereby improving the quality of the compost.
High temperature rainy season piled up high efficiency straw fertilizer
High temperature and rain in summer is a good time to build straw fertilizer. At this time, the straw resources are abundant, especially wheat straw and weeds are readily available. According to the test, when the straw fertilizer is accumulated, some chemical fertilizer, quicklime and excrement are properly incorporated, which not only has a high speed, but also has high fertilizer efficiency and good quality.
