Embodiment 1

[0030] The soil expansion and storage compatibilizer prepared by the domestic slag of the present embodiment is composed of the following raw materials and their weight percentages: domestic slag powder: 40%, potassium dihydrogen phosphate: 10%, diammonium phosphate: 20%, rapeseed residue: 10% %, urea: 1%, high-fat film: 1%, mixed crop straw powder: 18%.

[0031] The process for making the above-mentioned soil expansion and storage compatibilizer specifically includes the following steps (Fig. 1):

[0032] (1) Eliminate domestic slag for other purposes. Classify domestic slag, then pulverize and grind it to less than 1mm (20 mesh), and sieve it for later use after grinding.

[0033] (2) Air-dry the auxiliary materials potassium dihydrogen phosphate, diammonium phosphate, rapeseed residue, and mixed crop straw, pulverize, grind, and pass through a 1 mm sieve (20 mesh) for later use.

[0034] (3) Mix 40% of domestic slag powder, 10% of potassium dihydrogen phosphate, 20% of diam...

Embodiment 2

[0037] The difference between this example and Example 1 is that the ingredients of the raw materials are different, and the preparation method is the same as that of Example 1.

[0038] Raw materials and their weight percentages are: domestic slag powder: 35%, potassium dihydrogen phosphate: 15%, diammonium phosphate: 15%, rapeseed residue: 15%, urea: 2%, high-fat film: 1.5%, and crop mix Straw Powder: 16.5%.

Embodiment 3

[0040] The difference between this example and Example 1 is that the ingredients of the raw materials are different, and the preparation method is the same as that of Example 1.

[0041] Raw materials and their weight percentages are: domestic slag powder: 45%, potassium dihydrogen phosphate: 18%, diammonium phosphate: 15%, rapeseed residue: 10%, urea: 1%, high-fat film: 1%, and crop mix Straw Powder: 10%.

Abstract

This invention discloses a method for producing storage-increasing compatilizer for soil from domestic oven slag. The storage-increasing compatilizer is composed of: domestic oven slag 35-45%, potassium dihydrogen phosphate 10-20%, diammonium phosphate 15-20%, rape residue 10-15%, urea 1-3%, and high-fat film 1-2%. The method comprises: (1) selecting domestic oven slag, pulverizing and milling to below 1 mm (20 mesh); (2) air-drying the auxiliary materials, pulverizing, milling, and sieving with 20 mesh sieve; (3) mixing, stirring uniformly, and packaging or granulating. The storage-increasing compatilizer is applied by 750-1500 kg per ha soil, and can increase cotton yield by more than 12%, and increase water utility by more than 10%. The storage-increasing compatilizer can also retain water and fertilizer, and improve soil fertility.

Description

technical field [0001] The invention relates to a novel soil water-retaining agent, a fertilizer-retaining agent product and a production method thereof. In particular, using waste resources (urban and rural domestic slag) as raw materials to prepare a soil expansion and storage compatibilizer and its production method, this method opens up a new way for water-saving agriculture and comprehensive utilization of urban and rural waste resources to turn waste into treasure. It has obvious social benefits, environmental benefits and ecological benefits. Background technique [0002] 1. Study on the effect of using urban and rural solid waste to produce organic compound fertilizer [0003] Urban and rural domestic garbage and fly ash are rich in nitrogen, phosphorus, potassium and other nutrients needed for crop growth and a large amount of organic matter, which can be fully utilized in agricultural production. Sludge, garbage and fly ash are composted a...
