preparation example Construction

[0043] In a specific embodiment of the present invention, the schematic flow chart of the preparation method of the bio-organic soil improvement nitrophosphate fertilizer is as follows: figure 1 shown, including the following steps:

[0044] Weigh the soil improvement additive according to the proportion, add it evenly into the phosphorus nitrate fertilizer slurry through the feeding tank on the platform and micro-metering equipment, control the temperature at 135-155°C, control the residence time for 5-10 minutes, and mix and stir evenly to prepare the mixed slurry;

[0045] The mixed slurry enters the granulator, and at the same time, the organic material is directly fed into the granulator through the reserved feeding port together with the returned material. Under the condition of the spindle speed of the granulator at 80-150rpm, the mixing granulation produces 0.5-5.5 mm solid particles; temperature controlled at 50-100°C

[0046] After the solid particles pass through t...

Abstract

The invention provides a biological organic soil-improving nitrophosphate fertilizer. The biological organic soil-improving nitrophosphate fertilizer is prepared from the following raw materials in parts by weight: 85-98 parts of nitrophosphate fertilizer slurry; 0.2-3 parts of a soil improvement auxiliary agent; 0.3-5 parts of an organic material; and 0.1-1 part of a microbial agent. According to the invention, the soil improvement auxiliary agent, the organic material and the microbial agent are respectively injected into different working sections of the nitrophosphate fertilizer, so that the defect of single functional characteristic of a nitrophosphate fertilizer product is overcome, and the soil improvement auxiliary agent can improve the granular structure of soil, loosen soil, retain water, ventilate and increase oxygen supply of root cells; the organic material can increase the content of organic matters in soil, fertilize the soil and reduce nutrient loss; the microbial agent can regulate a rhizosphere microenvironment, cultivate a healthy root system and promote rhizosphere nutrition absorption; the three components have a synergistic effect, so that the water storage and fertilizer conservation capabilities of the soil are improved from three major latitudes of a soil physical structure, soil fertility performance and a micro-domain environment, and a healthy soil environment is created.
