n China, people’s living standards have been continuously improved, and the problem of food and clothing has been basically solved. High-yield and high-quality agricultural products and hygienic and healthy food have become the urgent needs of the current society and agricultural production.
China’s use of chemical fertilizer ranks first in the world, and the excessive use of chemical fertilizer leads to the decline of the quality of ecological factors in agricultural production. In China, the actual utilization rate of chemical fertilizer is less than 30%. The intensification of excessive use of chemical fertilizer leads to a large reduction of beneficial bacteria in the soil, a decline in soil quality, a reduction in self-purification ability, affecting the yield and quality of crops, endangering human health, and even the risk of environmental retaliation. Hazards of using fertilizer:
1、 Reduce crop productivity
As a result, the soil is hardened, the content of soil organic matter is reduced, the fertility is decreased, and the living space and quantity of beneficial microorganisms in the soil are reduced. The disease resistance, cold resistance, drought resistance and lodging resistance of crops are weakened, and the occurrence of diseases and insect pests is becoming more and more serious, leading to the decline of crop quality and yield.
2、 Aggravate environmental pollution. If too much fertilizer exceeds the soil’s retention capacity, it will flow into the surrounding water, resulting in agricultural water pollution, eutrophication of water body, algae breeding, and then damage the water environment. According to statistics, more than 10 million tons of nitrogen are lost out of farmland every year due to unreasonable fertilization in China, resulting in a direct economic loss of about 30 billion yuan. Excessive fertilizer will also seep into the shallow groundwater within 20 meters, making the nitrate content of groundwater increase.
3、 Waste a lot of scarce resources. If the wasted chemical fertilizer can be saved, the energy shortage in China will be alleviated. In 2004 alone, China’s fertilizer production consumed about 100 million tons of standard coal, more than 5% of the national energy consumption. In addition, China’s fertilizer production consumes more than 100 million tons of high-grade phosphate ore every year, and phosphate ore has been listed in the list of scarce resources by the Ministry of Land and Resources after 2010; Fertilizer production also consumes 72% of China’s sulfur resources.
The organic fertilizer production line uses modern microbial technology, mainly livestock and poultry excrement, and bran, peanut shell powder, crop straw and other auxiliary materials as carriers. The bacteria and livestock and poultry excrement are fully mixed by mixing method, so that the microbial bacteria are connected to the livestock and poultry excrement, including dehydrator, fermentation turner, semi-wet material crusher, horizontal mixer, granulator, dryer, cooler, drum screening machine, film coating machine The bio-organic fertilizer produced by packaging equipment, belt conveyor and other equipment after a series of harmless treatment such as rapid heating, fermentation, decomposition and deodorization.
