Double-effect water-protecting fertiliser and preparation method thereof

Abstract

The present invention discloses a double-effect water-protecting fertiliser and a preparation method thereof, wherein per 1000kg finished product of the double-effect water-protecting fertilizer is composed of the following components by weight: 40.0 to 80.0kg of biochemistry fulvic acid, 225.0 to 265.0kg of carbamide, 60.0 to 100.0kg of calcium ammonium nitrate, 200.0 to 250.0kg of mammonium dihydrogen phosphate, 80.0 to 120.0kg of magnesium kalium sulphuricum, 135.0 to 175.0kg of kalium sulphuricum, 0.5 to 3.5kg of borax, 2.0 to 6.0kg of copper sulfate, 10.0 to 18.0kg of zinc sulfate, 5.0 to 15.0kg of toluol methylpyrrolidine, 10.0 to 40.0kg of crosslinked polypropylene acidamide and polyacrylic acid potassium salt copolymer, and 10 to 40kg of attapulgite powder clay. the fertiliser not only meets the food supply required by the health growth of farm crops, is also capable of improving the utilization efficiency of the soil moisture and having non harm to human and animal husbandry without environment pollution.

Description

1. Technical field [0001] The invention relates to a novel double-effect water-retaining fertilizer applied in agricultural production, in particular to a pollution-free fertilizer integrating nutrition, insecticidal and water-retaining functions. 2. Background technology [0002] The total area of ​​arid and semi-arid areas in my country accounts for about 50% of the total land area. my country's agriculture is also a large water user. The agricultural water consumption exceeds 70% of the total water consumption, but the production efficiency is very low. The annual agricultural water shortage in my country is about 30 billion m 3 , the agricultural water crisis is intensifying. Soil water retaining agent is a polymer with super high water absorption and water retention capacity. It has the functions of enhancing soil water retention, improving soil structure, reducing deep water leakage and soil nutrient loss, and improving water use efficiency. However, the use of soil w...

Problems solved by technology

At present, the prevention and control of crop pests mostly depends on chemical pesticides. However, due to the relatively long residual period of chemical pesticides, it not only pollutes the soil environment, but also affects the quality of agricultural products. It is not suitable for the production of pollution-free agricultural products, especially agricultural products for export.
