Embodiment Construction

[0016] An oxygen-increasing coated fertilizer for saline-alkali soil improvement, made of the following raw materials in parts by weight (kg): seaweed 10, bagasse 43, soy sauce residue 24, disodium edetate 2, ferrous sulfate 3, Ammonium chloride 5, talcum powder 4, urea 6, 30% hydrogen peroxide solution 10, laxogenin powder 1, butyl acrylate 0.5, sodium dihydrogen phosphate dry powder 1, nano-zinc oxide 0.6, appropriate amount of water.

[0017] The concrete steps of the preparation method of the oxygen-increasing coated fertilizer of the saline-alkali soil improvement are as follows:

[0018] (1) Mix seaweed, bagasse, and soy sauce slag and put them in the fermentation tank, control the water content to 34% of the maximum water content of the fermentation heap, retting and fermenting for 3 weeks, after the fermentation is completed, dry the fermented material and crush it into dry spare material;

[0019] (2) Mix Laxogenin powder with disodium edetate and ferrous sulfate, ad...

Abstract

The invention discloses oxygenation coated fertilizer for improvement in saline alkali soil. The oxygenation coated fertilizer is prepared from, by weight, 10-12 parts of algae, 43-47 parts of sugarcane bagasse, 24-25 parts of soy sauce residues, 2-3 parts of ethylenediamine tetraacetic acid disodium, 3-4 parts of ferrous sulfate, 5-6 parts of ammonium chloride, 4-5 parts of talcum powder, 6-8 parts of urea, 10-12 parts of 30% hydrogen dioxide solution, 1-2 parts of laxogenin powder, 0.5-0.7 part of butyl acrylate, 1-2 parts of sodium dihydrogen phosphate dry powder, 0.6-0.7 part of nano zinc oxide and an appropriate amount of water. The fertilizer has a lot of bioactive factors and probiotics, can effectively expand distribution of organic matter in soil and solve the problems of soil salinization, barren organic matter and others caused by dependence on fertilizer all the year round, and especially can increase soil aggregates, improve permeability and improve soil fertility and the physicochemical structure of salinity soil so that the soil can be suitable for normal growth of crops.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an oxygen-increasing coated fertilizer for saline-alkali soil improvement. 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, and th...
