Description
Technical Field
The invention relates to the field of soil improvement, in particular to a preparation method of a soil conditioner and a soil improvement method.
Background
The soil is a layer of loose substances on the earth surface, and consists of various granular mineral substances, organic substances, moisture, air, microorganisms and the like, plants can grow, the soil consists of mineral substances formed by rock weathering, animals and plants, organic substances generated by microbial residue decomposition, soil organisms (solid phase substances), moisture (liquid phase substances), air (gas phase substances), oxidized humus and the like, the acid soil is soil with pH of less than 6.5, the acid soil accounts for about 40% of the cultivated area of the world, the acid soil accounts for about 20% of the cultivated area of China, the acid soil has high concentration of H+, al3+, mn2+, fe2+ and the like, the acid soil can influence nutrient absorption and utilization of plants after acidification, the acid soil and the alkali soil are required to be regulated regularly, the soil conditioner is also called as soil conditioner, the soil conditioner can improve nutrient absorption of crops, the soil conditioner has the effect principle that soil particles are adhered with a lot of small soil particles to form large aggregates, and water is stable, and the soil conditioner is widely applied to prevent erosion of soil, reduce soil transpiration or save water, promote healthy water growth of plants.
At present, after the soil is used for a long time, the fertility in the soil is lost, the soil nutrition is unbalanced, the acid and alkali are unbalanced, the plate problem is easy to occur, the effective use of the soil and the healthy growth of crops are further affected, and a soil conditioner preparation method and a soil conditioning method are needed, so that the problems in the prior art can be solved.
Disclosure of Invention
The invention aims at: the soil conditioner preparation method and the soil conditioning method are provided for solving the problems that after the soil is used for a long time, the fertility in the soil is lost, the soil nutrition is unbalanced, and the plate problem is easy to occur, so that the soil use and the healthy growth of crops and the fertility easily lost after the soil conditioning are affected.
In order to achieve the above purpose, the present invention provides the following technical solutions: a preparation method of a soil conditioner and a soil conditioning method, wherein the soil conditioner comprises ammonium bicarbonate, polyglutamic acid, chitosan oligosaccharide, ammonium sulfate powder, sheep manure and humic acid.
Preferably, the mass percentages of the components are as follows:
the addition amount of ammonium bicarbonate is 5-20%;
the addition amount of the polyglutamic acid is 2-7%;
the addition amount of the chitosan oligosaccharide is 1-3%;
the addition amount of the ammonium sulfate powder is 1-6%.
Preferably, the method comprises the following preparation steps:
step one: mixing ammonium bicarbonate, polyglutamic acid, chitosan oligosaccharide and ammonium sulfate powder according to a proportion, adding an adhesive and water, and mixing to obtain a solution;
step two: cleaning sheep manure and rotten leaves, drying, crushing into superfine powder by using a crusher after drying, and crushing the sheep manure and the rotten leaves according to the proportion of 1:1 and the solution to prepare the soil conditioner.
Preferably, the molecular weight of the polyglutamic acid is below 2 ten thousand, the polyglutamic acid has excellent water solubility, super-strong adsorptivity and biodegradability, the total mass ratio of the adhesive to ammonium bicarbonate, polyglutamic acid, chitosan oligosaccharide and ammonium sulfate powder is 3:5, bicarbonate in the ammonium bicarbonate reacts with hydrogen ions in water to make the solution slightly alkaline and harmonize the acidity of soil, and ammonium sulfate provides oxygen and hydrogen ions required in oxidation-reduction reaction for acidic soil, neutralizes the acidity of soil and provides trace elements required by plants.
Preferably, the chitosan oligosaccharide can improve the content of cold-resistant substances such as soluble protein, soluble sugar and the like, reduce the level of peroxidation of membrane lipid and the degree of increase of membrane permeability, maintain higher photosynthetic strength of crops, have the functions of resisting bacteria and inducing plants to produce chitinase in plant cells and tissues, improve enzyme activity, promote protein synthesis, regulate closing and opening of plant genes and induce synthesis of auxin indoleacetic acid (IAA).
Preferably, the method comprises the following improvement steps:
step one: after farmland cleaning, the surface of the farmland soil is cleaner, and soil turning is not needed;
step two: diluting the soil conditioner with water according to a certain proportion to prepare a spray agent, and dripping the spray agent into soil through spray irrigation;
step three: then spreading corncob powder;
step four: mixing the corncob fragments with a soil conditioner diluent to absorb the moisture of the conditioner, so that the moist corncob fragments can be tightly adsorbed with the soil;
step five: uniformly spreading melon seed shells on the surface layer of the soil, and wrapping a mulching film.
Preferably, organic fertilizer, crop straw and the like are deeply turned to the lower layer to serve as the base fertilizer of the soil in the first two weeks of the spraying of the soil conditioner.
Preferably, the soil conditioner is sprayed after the organic fertilizer is decomposed.
Preferably, the corncob is crushed by a crusher after natural air drying, and the crushed corncob is approximately the same as the soil conditioner in size.
