Embodiment Construction

[0016] An oxygen-increasing coated fertilizer prepared from low-quality phosphate rock, made of the following raw materials in parts by weight (kg): 22 low-quality phosphate rock, 32 chicken manure, 10 fresh orange peel, 1 gluconolactone, 1 cobalt sulfate, Sodium dihydrogen phosphate 2, straw ash 6, urea 11, 30% hydrogen peroxide solution 15, laxogenin powder 1, butyl acrylate 0.8, sodium dihydrogen phosphate dry powder 2, nano zinc oxide 1.4, water as appropriate.

[0017] The specific steps of the preparation method of the oxygen-increasing coated fertilizer prepared by using inferior phosphate rock are as follows:

[0018] (1) Airtightly calcinate low-quality phosphate rock at 450°C for 2 hours, take it out and cool it, mix it with chicken manure and fresh orange peel, and put it in the fermentation tank. After 20 days, after the fermentation is completed, the fermented material is dried and crushed into dry material for later use;

[0019] (2) Mix Laxogenin powder with gl...

Abstract

The invention discloses an aerobic coated fertilizer prepared from inferior phosphorus ore. The aerobic coated fertilizer is prepared from, by weight, 22-26 parts of the inferior phosphorus ore, 32-35 parts of chicken manure, 10-12 parts of fresh orange peel, 1-2 parts of glucolactone, 1-2 parts of cobalt sulfate, 2-3 parts of sodium dihydrogen phosphate, 6-8 parts of straw ash, 11-13 parts of urea, 15-17 parts of a 30% hydrogen peroxide solution, 1-2 parts of laxogenin powder, 0.8-0.9 part of butyl acrylate, 2-3 parts of dry sodium dihydrogen phosphate powder, 1.4-1.6 parts of nano-zinc oxide and an appropriate amount of water. According to the fertilizer, a large quantity of harmful substances in the inferior phosphorus ore are removed through a calcination means, the inferior phosphorus ore is integrated into a fertilizer through fermentation, therefore, the content of mineral nutrients of the fertilizer is increased, the proportion of nitrogen, phosphorus, potassium and medium and trace elements is balanced, the lodging resistance and disease resistance of crops are improved, and meanwhile a new method is provided for recycle of the inferior phosphorus ore.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an oxygen-increasing coated fertilizer prepared by using inferior phosphate rock. Background technique [0002] With the abnormal global climate, heavy rains and floods occur frequently in some areas. At the same time, factors such as improper irrigation or poor drainage often cause waterlogging in crop land, making the soil in a state of flooding. Under flooding conditions, the gas in the soil is forced to discharge. It is easy to cause insufficient oxygen in the soil. Oxygen is necessary for plant root respiration. Long-term hypoxia will hinder the electron transfer of plant cells, accumulate a large amount of active oxygen, damage the structure and function of cell membranes, and even cause a large number of crops to die. Under hypoxic stress, the root system accumulates a large amount of toxic substances such as ethanol and lactic acid, the root metabolism is disordered,...
