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.
　　
Phosphate-containing fertilizer   First , mix 3% to 5% of superphosphate with soil and beef fertilizer, pile up for 10 to 15 days, and mix with straw at a ratio of 1 : 2 to promote microbial activity and poorly soluble phosphorus. The conversion 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.
　　
Calcium-containing fertilizer method   Firstly , mix 100 kg of water and 3 kg of quicklime , and then add 4 to 6 kg of lime water per 100 kg of straw to remove the wax on the surface of the straw, so that the straw is softened and succulent, so that it can be absorbed by water as soon as possible. It can shorten the curing time and also improve the fertilizer efficiency.

Mixed manure and urine accumulation method   First, add the straw to the water for about 20 days, ferment it, and then add 20 to 30 kg of manure and excrement per 100 kg of straw . Mix well and then ferment the fermentation. This will increase the microbial activity and increase the organic matter content in the compost. The nutrients that are easily lost in human excrement are absorbed into the organic matter of the straw, thereby improving the quality of the compost.
