preparation example 1

[0042] Preparation Example 1: Preparation of biogas residue

[0043] The biogas residue with animal manure as raw material was separated into solid and liquid to obtain a slag with a water content of 45 wt%, which was then heated and dried to obtain a slag with a water content of 5 wt%, which was sheared and crushed and ground to a particle size of 400 nm. Obtain the biogas residue and keep it for subsequent use;

preparation example 2

[0044] Preparation Example 2: Preparation of Wood Vinegar

[0045] Take the crude wood vinegar collected at the exhaust outlet temperature of carbon dry distillation equipment at a temperature of 90-100°C, let it stand for 45 days, remove the oil on the surface of the liquid, take out the middle liquid part without bottom precipitation, and add charcoal powder of 7.5% of its weight , and filter after mixing to obtain the wood vinegar, which is reserved for subsequent use;

preparation example 3

[0046] Preparation Example 3: Preparation of Mineral Powder

[0047] Mix medical stone, hydroxyapatite and dolomite according to the mass ratio of 1:0.8:1.2, then add zinc pyrithione solid powder, cassia seed and camellia japonica, pass through a 100-mesh sieve after grinding fully, and mix the powder evenly , to obtain the required mineral powder, which is reserved for subsequent use; wherein the mass ratio of medical stone, zinc pyrithione, cassia seed and golden camellia is 1:0.3:0.5:0.2;

Abstract

The invention relates to a composite soil conditioner, comprising biogas residues, pyroligneous acid, mineral powder, soluble chitosan, diethylene triaminepentaacetic acid pentasodium, a surfactant, tobacco powder, trehalose, di-rhamnolipid, a flocculating component, a penetrating agent, enteromorpha powder, modified zeolite, boron-zinc-magnesium-containing fungicide, a nano additive, an accelerant, pentaerythritol triacrylate and ionic liquid, preferably also comprising 4-methyl phenyl valerate which is equal to the ionic liquid in weight. The novel composite soil conditioner has excellent soil improvement and recovery performance, the utilization rate of the fertilizer by the crop is greatly increased, and the composite soil conditioner can significantly increase the yield, simultaneously also can improve the permeability of the soil and avoids side effects of heavy metals such as cadmium; thus, the composite soil conditioner is beneficial to crop growth and has a wide industrial application prospect.

Description

technical field [0001] The invention relates to a soil conditioner, in particular to a multi-component composite soil conditioner, which belongs to the technical field of agriculture. Background technique [0002] Maintaining and improving soil fertility and promoting soil productivity to crops have increasingly become the focus of the country, society and many scientific research institutions. Whether this problem can be successfully solved is also a key point related to population growth and social supply; [0003] In the field of crop cultivation today, it often involves a large amount of chemical fertilizers, pesticides, herbicides, insecticides and other substances, which is a universal method to increase production. However, this method will cause imbalance of soil nutrient content, soil compaction, increase of pathogenic bacteria, and decline of soil fertility, thereby affecting the yield and quality of crops, and more seriously, causing changes in the properties of t...
