Embodiment 1

[0024] The improving agent, calculated by weight percentage of dry weight, is 65% of chicken manure, 30% of phosphogypsum, and 5% of zeolite powder.

[0025] Before the ratio of raw materials, collect 5 samples of livestock manure and phosphogypsum respectively according to the multi-point sampling method, weigh 5-10 grams of each sample in an aluminum box, put it in a drying oven at 105°C-110°C After drying for 6-8 hours, calculate the water content by weight of the sample. The formula for calculating the dry weight of the sample is as follows:

[0026]

[0027] The water content of the sample weight is the average value of the results of 5 repeated measurements.

[0028] The actual weight of the sample taken should be the weight after deducting the water content. For example, the water content of a fresh chicken manure is 60%. The weight of is 65(1+60%)=104 kg.

[0029] Improver preparation method:

[0030] According to the weight percentage of dry weight, mix 65% chi...

Embodiment 2

[0034] The difference from Embodiment 1 is that this embodiment can be used in factory production. Mix the chicken manure, phosphogypsum, and zeolite powder in proportion in Example 1, spread it on the ground and dry it in the shade for 3-5 days, then put it into the drying equipment and dry it at about 120-150°C, and put it into the mixer Stir evenly in the medium, pass through a 40-80 mesh sieve, and get the finished product after bagging.

Embodiment 3

[0036] The difference from Example 1 is that the weight percentages of the dry weights of the three raw materials are different.

Abstract

The invention relates to a soil modifier, specifically, relating to a mixed soil modifier with dejecta of domestic animal and poultry and phosphogypsum as main raw materials and preparation method thereof. The soil modifier comprises dejecta of domestic animal and poultry 50% to 65%, phosphogypsum 25% to 45%, and zeolite 5% to 10% according to dry weight percent, comprising steps of: mixing said raw materials in proportion, paying them on ground, drying them in shade, then processing air-dry treatment, to obtain finished product; for manufactory production, drying mixture after air-dry treatment, agitating it evenly, selecting it by sieve, packaging it to obtain the finished product. The preparation of the invention is simple with low finished product cost, adaptable to saline soil modification, and modification and repair of magnesite dust-polluted soil.

Description

technical field [0001] The invention relates to a soil conditioner, in particular to a mixed soil conditioner and a preparation method thereof. Background technique [0002] In recent years, my country's livestock and poultry breeding industry has developed rapidly, and the development of the livestock and poultry industry has led to the aggravation of breeding pollution. According to the results of pollution investigation and estimation, in 1988, the loss of livestock and poultry pollutants COD (chemical oxygen demand of water pollutants), nitrogen, and phosphorus were 4.551 million tons, 2.494 million tons, and 237,000 tons, respectively. In 2001, they were 6.896 million tons. 10,000 tons, 3.693 million tons and 297,000 tons. In 1999, the total amount of livestock and poultry manure produced in my country was about 1.9 billion tons, while the industrial solid waste of various industries in the country was 780 million tons in the same period, and the production of livestoc...
