Background
Fertilization is the most effective way to increase crop yield. The research shows that the organic fertilizer or functional biological organic fertilizer can not only obviously improve the soil biological activity, but also play an outstanding role in regulating and controlling healthy soil microflora and preventing and controlling soil-borne diseases. The organic wastes are changed into pollution sources to serve as nutrient resources, scientific and reasonable organic fertilizer and inorganic fertilizer proportion is explored to form a refined organic fertilizer or a functional biological organic fertilizer, so that the purposes of reducing weight, improving efficiency and improving the efficient utilization of the nutrient resources are achieved, and key problems of promoting inorganic materials by organic matters, improving the utilization rate of chemical fertilizers, constructing a healthy soil microbial community, reducing soil-borne diseases, improving the sustainable utilization of soil and the like are also concerned. However, according to investigation, the amount of the homogenized fertilizer per mu in China is 21.9 kg, which is far higher than the average level (8 kg per mu) in the world, and is 2.6 times of that in the United states and 2.5 times of that in European Union, and problems of excessive application and blind application of chemical fertilizers and the like bring about cost increase and environmental pollution. The soil hardening and acidification are caused by the large-scale application of the fertilizer, the soil is unhealthy, the unhealthy soil causes crop diseases and causes unhealthy plants, and the unhealthy plants need to be sprayed with pesticide; the pesticide reduces and even kills a plurality of microorganisms and floras in the soil, and a plurality of biological processes in the soil are slowed down or stopped, so that organic matters and beneficial microorganisms in the soil are greatly reduced, and the soil fertility is seriously exhausted.
In the prior art, compound fertilizer burns out the heat-up to the drying furnace before other processes do not start, and the stove internal temperature reaches 400 ℃, and the air outlet temperature reaches within 100 ℃, and in the material sent into the drying furnace through the conveyer belt after mixing, pelletization, start the hot-blast furnace and rotate about 30 minutes, hot-blast furnace start exhaust system simultaneously, semi-manufactured goods flow out from the air outlet and get into next conveying system. However, due to the environmental protection standard, the coal is not allowed to be used for boiler combustion, and is changed into biomass combustion, so that the cost is multiplied, and the secondary pollution to different degrees is caused to the environment due to the fact that the chemical fertilizer gas smell after high temperature is emitted in the drying process.
