Embodiment Construction

[0015] A. Grinding: Grinding the calcium magnesium phosphate fertilizer, blast furnace slag, humic acid and carboxymethyl cellulose to 150-200 mesh respectively; the calcium magnesium phosphate fertilizer comes from Yunnan Province, Guizhou Province or Sichuan Province, and its composition contains : Phosphorus pentoxide ≥ 18%, magnesium oxide ≥ 12%, silicon dioxide ≥ 20%, blast furnace slag comes from major steelmaking plants across the country, and humic acid comes from Xinjiang;

[0016] B, mixing: calcium magnesium phosphate fertilizer, blast furnace slag, humic acid: carboxymethyl cellulose=20-24: 63-68: 10-1: 1 ratio will grind calcium magnesium phosphate fertilizer, Blast furnace slag, humic acid and carboxymethyl cellulose are uniformly mixed to form a mixed powder;

[0017] C. Granulation: first feed the mixed powder into the drum granulator, and more than 50% of the mixed powder in the drum granulator forms a master batch with a particle size of 0.5mm-1mm, and then m...

Abstract

The invention relates to soil conditioner which can improve the acidity of the soil; while the soil conditioner improves the acidity of the soil, the soil conditioner can provide a plurality of nutrient elements for the soil to guarantee the major, medium and microelements for the growth of the plants; the soil conditioner and the preparation method include that the soil conditioner is prepared through the steps as the followings: calcium magnesium phosphate, blast furnace slag and humic acid are grinded respectively; and then the grinding materials are mixed evenly, granulated and dried sequentially according to certain weight ratio; the soil conditioner is composed of 3%-4% of phosphoric anhydride, 20%-30% of silicon dioxide, 3%-5% of magnesia and 8%-10% of organic matter; when the soil conditioner in the invention is adopted, not only the acidity of the soil is improved, but also the content of the soil nutrient is increased.

Description

technical field [0001] The invention relates to a soil conditioner and a preparation method thereof. Background technique [0002] At present, in the cultivation of crops, the normal growth and harvest of crops are often affected by the acidity or alkalinity of the soil. Reduce crop yield and poor quality. In terms of soil acidity and alkalinity conditioning recently, some products have made some progress in soil acidity improvement, such as the patent number: 200410008771.1 "A method for improving acidic soil by using papermaking wastewater to treat sludge". The method of improving the soil environment using lignin sludge as a material is more realistic and easy to implement, but while improving the soil, if it can continuously provide other ingredients needed by crops during the growth process, it can achieve twice the result with half the effort and make the soil While the acidity is adjusted, some trace elements in the medium are increased, which is beneficial to the g...
