Clayed soil conditioner containing straw biomass charcoal

Abstract

The invention discloses a clayed soil conditioner containing straw biomass charcoal. The clayed soil conditioner is prepared from the following raw materials in parts by weight: 1 to 2 parts of yellow phosphorus slag, 3 to 5 parts of humic acid, 4 to 6 parts of waste residues of a brewhouse, 40 to 60 parts of sand, 5 to 8 parts of oyster shell, 1 to 2 parts of pseudolari cortex, 1 to 2 parts of radix scutellariae, 0.8 to 1 part of garlic leaves, 0.2 to 0.4 part of herba hyperici perforati, 1 to 2 parts of syringa oblata, 130 to 140 parts of straws, 1 to 2 parts of alkyl glycoside, 0.2 to 0.3 part of glycine betaine, 0.4 to 0.8 part of carrageenan, and 1 to 2 parts of chitosan.

Description

technical field [0001] The invention relates to the technical field of soil improvers, in particular to a sticky soil improver containing straw biochar. Background technique [0002] Cohesive soil is produced by the interaction between clay particles and water, and the clay soil and its soil particles are mostly composed of silicate minerals. Strong water and fertilizer retention capacity, but small pores, poor air and water permeability, sticky when wet and hard when dry. [0003] All materials that are mainly used to improve the physical, chemical and biological properties of the soil to make them more suitable for plant growth, rather than mainly providing plant nutrients, are called soil amendments. [0004] The element composition of biochar mainly includes carbon (generally up to 60%), hydrogen, oxygen, etc., followed by ash (including potassium, calcium, sodium, magnesium, silicon, etc.), which is a carbon-containing polymer, Fourier Leaf infrared photoacoustic spec...

Problems solved by technology

[0008] At present, most of the soil amendments are improved in terms of how to improve fertility, but seldom involve in the control of underground pests.
