Special organic compound modifier used in carbonate-type paddy fields and preparation method thereof

Abstract

A special organic compound modifier used in carbonate-type paddy fields and a preparation method thereof relate to a special organic compound modifier used in paddy fields and a preparation method thereof. The modifier and the preparation method thereof solve the problems of soil hardening easily caused by modifiers used in the carbonate-type paddy fields, worsening of physicochemical properties,poor effect on reducing soil alkalinity and high preparation cost. The modifier is made from the following materials by mass percentages: 50-60% of furfural residue, 5-12% of furnace ash, 30-35% of animal manure and 3-7% of brown coal. The preparation method comprises the following steps: blending the furfural residue and the furnace ash to obtain a mixture; mixing the animal manure and the browncoal for fermentation, and obtaining an organic fertilizer; mixing the mixture and the organic fertilizer for fermentation, and then sequentially granulating, ball blasting, sieving and packaging, thus obtaining the modifier. The modifier contains 60-70% of organic matter with pH of 3-4, and has advantages of convenient use, easy mechanical application at large area, simple preparation process andlow cost of raw materials.

Description

technical field [0001] The invention relates to a paddy field organic compound special improver and a preparation method thereof. Background technique [0002] The lack of correct understanding of different regions, different degrees, and different types of salinized soils, and the lack of scientific basis for the use of improved substances limit the improvement effect of carbonate-type alkaline rice fields and the application of organic amendments. Promotional use. [0003] In my country, in the research of chemical modifiers for carbonate-type alkaline rice fields, the substrates are mostly gypsum, fly ash, sludge, etc. Some improved substrates themselves contain ingredients that are harmful to plants, and there is no limit on the amount used when improving saline-alkali soil. For example: both fly ash and phosphogypsum contain magnesium chloride (MgCl 2 ), and will re-input Cl into the soil during improvement - , aggravated by Cl - Toxic effect on soil; sludge contai...
