Embodiment Construction

[0017] A special modified rice straw soil modifier for red soil, made of the following raw materials in parts by weight (kg): cassava residue 23, bird droppings 27, quicklime 4, chitosan oligosaccharide 3, sodium iron ethylenediaminetetraacetate 2.8, Sodium pyrophosphate 2, calcium ammonium nitrate 7, rice straw 52, ​​monochloroacetic acid 2.2, kaolin 13, calcium-based bentonite 5, appropriate amount of water.

[0018] The specific steps of the preparation method of the special modified rice straw soil modifier for red soil are as follows:

[0019] (1) Mix cassava residue, chitosan oligosaccharides, and guano into the fermentation tank, and add water until the water content of the fermentation heap is 30%. After 2 weeks of fermentation, add water to the maximum water content of the fermentation heap to 70% and continue fermentation After 12 days, after the fermentation is completed, the fermented heap is crushed and squeezed to obtain fermented residue and fermented liquid for...

Abstract

The invention discloses a modified-rice-straw soil modifier for red soil. The soil modifier is made from the following raw materials, by weight part, 23-25 of cassava residue, 27-28 of bird droppings, 4-5 of quick lime, 3-4 of chitosan oligosaccharide, 2.8-3.2 of sodium ferric ethylene diamine tetraacetic acid, 2-3 of sodium pyrophosphate, 7-8 of calcium ammonium nitrate, 52-55 rice straw, 2.2-2.4 of monochloro acetic acid, 13-14 of kaolin, 5-6 of calcium-based bentonite and a proper amount of water. The soil modifier aims to solve problems of hardening and acidification of red soil. Through addition of alkaline raw materials and organic raw materials, the unit weight of the red soil is effective reduced, the content of water stable aggregate and organic matters in the red soil are added, and the red soil is loosened. The physical biological indices of the red soil are overall improved, thereby achieving the purpose of high yield of plant growing in the red soil.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a special modified rice straw soil modifier for red soil. Background technique [0002] my country's agriculture is relatively developed, and it is a large agricultural country with a long history. A large amount of agricultural solid waste is produced every year, such as sugarcane dregs, rice husks, rice and wheat straw, etc. These agricultural solid wastes are often not comprehensively utilized in a timely manner, and are dumped and incinerated indiscriminately, causing huge pollution to the environment. The use of low-quality agricultural solid waste as raw material for soil improvement has become a research hotspot in the field of high-quality solid waste utilization and environmental restoration. Through simple physical or chemical treatment of these solid wastes, the adsorption performance of heavy metals and organic pollutants in the soil can be improved, the phy...
