Embodiment 1

[0029] The soil expansion and storage compatibilizer of this embodiment is composed of the following raw materials and their weight percentages: corn stalks: 40%, potassium dihydrogen phosphate: 10%, diammonium phosphate: 20%, rapeseed residue: 10%, urea: 1 %, high fat film: 1%, crop mixed straw: 18%.

[0030] The method for making the above-mentioned soil expansion and storage compatibilizer specifically comprises the following steps:

[0031] (1) The raw material is corn stalks among crops, crushed and ground to less than 1 mm (20 mesh), and sieved after grinding for later use.

[0032] (2) Air-dry auxiliary materials such as potassium dihydrogen phosphate, diammonium phosphate, rapeseed residue, and mixed crop straw, crush, grind, and pass through a 1 mm (20 mesh) sieve for later use.

[0033] (3) Mix 40% of corn straw powder, 10% of potassium dihydrogen phosphate, 20% of diammonium phosphate, 10% of rapeseed residue, 1% of urea, 1% of high-fat film, and 18% of crop mixed ...

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. Raw materials and their weight percentages are: corn stalk powder: 35%, potassium dihydrogen phosphate: 15%, diammonium phosphate: 15%, rapeseed residue: 15%, urea: 2%, high-fat film: 1.5%, crop mix Straw: 16.5%.

Embodiment 3

[0039] 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.

[0040] Raw materials and their weight percentages are: corn stalk powder: 45%, potassium dihydrogen phosphate: 18%, diammonium phosphate: 15%, rapeseed residue: 10%, urea: 1%, high-fat film: 1%, crop mix Straw: 10%.

Abstract

A water and fertilizer retaining agent of soil for increasing the yield of crops (more than 12%) is proportionally prepared from corn stalk, potassium bihydrogen phosphate, diammonium phosphate, rape dregs, urea, high-fat film, and the mixture of crop' s straw and stalk. Its preparing process is also disclosed.

Description

technical field [0001] The invention relates to a preparation method of a soil expansion and storage compatibilizer. In particular, a soil expansion and storage compatibilizer prepared by using waste resources (corn stalks) as the main raw material and a preparation method thereof open up a new way for comprehensive utilization of waste straw resources and turning waste into treasure. Background technique [0002] 1. Current Situation of Corn Stalks in my country [0003] The amount of crop straw resources in my country ranks first in the world. The sown area of ​​grain in my country is about 113 million hm 2 , the total grain output is 490 million tons, and the total output of corn, wheat and other cereal straws is 500 million tons. Adding the straw of other crops, the annual output of straw is more than 600 million tons. Although 250 million tons are used to make manure and return to the field; 48 million tons are used for industrial raw materials;...
