Problems solved by technology

[0004] The purpose of the present invention is to provide a method for preparing a special fertilizer for zinc high-efficiency corn that is suitable for calcareous soil, which is used to solve the problem in the prior art that the trace elements such as zinc needed for corn growth vary with time when corn is planted in calcareous soil. The water level drops and the loss is serious, and the balance of fertilizer is not enough, which directly affects the problem of planting and production

Abstract

The invention discloses a preparation method of a zinc-efficient special corn fertilizer applicable to calcareous soil. The preparation method comprises the following steps: respectively weighing and drying urea, ammonium sulfate, monoammonium phosphate, potassium sulfate, sulfur, zinc oxide powder and bio-based polyurethane for later use; uniformly mixing urea, ammonium sulfate, monoammonium phosphate and potassium sulfate, and carrying out granulating to obtain a fertilizer master batch; and putting the fertilizer master batch into a rotary drum, uniformly spraying sulfur, zinc oxide powder and bio-based polyurethane on the surface of the fertilizer master batch, and then putting the formed mixture into a drying oven for treatment until the mixture is completely dried so as to obtain the zinc-efficient special corn fertilizer. According to the invention, sulfur has an alkali adjusting function, can slowly acidify soil, can form zinc sulfate with zinc oxide to continuously provide sulfur and zinc nutrition for crops, and is a good material for sterilization; and the bio-based polyurethane can play a role in degradation and slow release, and can be continuously degraded along with increase in the burying time of the fertilizer in soil, so fertilizer nutrients coated by the bio-based polyurethane is released.

Description

Technical field [0001] The present invention relates to the field of soil chemical fertilizers, and in particular to zinc high-efficiency corn special fertilizer for peat-resistant soil. Background technique [0002] Compared with traditional rice, wheat and other food crops, corn has strong drought resistance, cold resistance, poor resistance, and excellent environmental adaptability. The nutritional value of corn is high, and it is excellent food crop. As China's high-yield grain crops, corn is an important feed source such as animal husbandry, aquaculture, aquaculture industry, and is also an indispensable raw material in food, health care, light industrial, chemical industries. The limestone soil is a soil generally known as the peat resistance of calcium carbonate or calcium carbonate. It features a lime reaction, that is, after the dropwise hydrochloric acid, the carbonate and an acid are used to produce carbon dioxide bubbles, which is alkaline in this soil. The reaction, ...
