Abstract
The invention discloses a preparing method of alkaline soil modifier, which comprises the following steps: dissolving polyacrylic acid in the water; adding inorganic acid, pyroligneous and plant hormone sequently; stirring to blend evenly. The modifier contains 5-25% polyacrylic acid, 10-50% inorganic acid, 1-5% pyroligneous, 0.01-2.0% plant hormone and water. The invention reduces soil pH value effectively, which is beneficial for plant growth.
Description
Affiliated technical field:
The present invention relates to a kind of preparation method of saline-alkali soil conditioner, promptly a kind of preparation method that can reduce soil pH value, soluble salt content and keep the modifying agent of moisture.
Background technology:
The soil salinization is a global problem to the threat of agricultural, and the world has about 1,000,000,000 hm now
2The saltings, account for land area nearly 25%.The salt damage that all is subjected in various degree of irrigateing land of the arable land in the whole world 20% and nearly half threatens.Only there are 100,000,000 hm of arable land in China
2, wherein surpass 0.2 hundred million hm
2Be salt wasteland and 0.067 hundred million hm
2Being salinization soil ground, is one of saltings, world big country.China is a large agricultural country, and agricultural development is one of important component part of the national economic development.The effective measure in saltings are administered in research, and the further improvement of its ecosystem is controlled on transformation salinity ground, will be to concern the major issue that Chinese national economy increases, and also be the important behave that sustainable development path is walked by China.
Salt affected soil is meant harmful salts such as the muriate that contains potassium, sodium, calcium, magnesium in the soil, vitriol, hydrocarbonate; Though or soil salt content is few, soil exchangeable sodium accounts for cation exchange capacity and has reached certain proportion.It has following feature, and 1, the pH value is higher; 2, contain harmful salinity; 3, ventilation property is poor, easily ties plate; 4, fertility is low.
Its main action principle of the saline-alkali soil conditioner that the present invention relates to is as follows:
Contained polyacrylic acid becomes to belong to complex polyelectrolyte particle, many carboxyl negative ions are arranged on the molecular chain after the ionization, there is powerful electrostatic force in these negative ions near making macromolecular chain, and positively charged ion is had very strong constraint effect, therefore can reduce the content of soluble salt in the soil.The acidity of self can in and the basicity of salt affected soil, reduce pH in soil; Wherein contained mineral acid can significantly reduce soil pH value; Wood vinegar contains the multiple material that helps plant-growth; Plant hormone can promote plant-growth.
This saline-alkali soil conditioner is applicable to land for growing field crops farm crop, lawn, careless pasture, saline-alkali wasteland, fruit tree, vegetables and ornamental plant.Liquid form, convenient spraying.
Summary of the invention:
The object of the present invention is to provide a kind of preparation method of saline-alkali soil conditioner, with polyacrylic acid with water dissolution after, under agitation add mineral acid, wood vinegar and plant hormone successively, mix.The mass percent of each material is: polyacrylic acid 5-25, mineral acid 10-50, wood vinegar 1-5, plant hormone 0.01-2.0, surplus is a water.
The saline-alkali soil conditioner of the present invention's preparation can effectively improve the soil particle state, improve the soil water-retaining performance, wherein contained polyacrylic acid becomes to belong to complex polyelectrolyte particle, can fetter metal ion, reduce the content of soluble salt in the soil, the acidity of self can in and the basicity of salt affected soil, reduce pH in soil; Wherein contained mineral acid can significantly reduce soil pH value; Wood vinegar contains the multiple material that helps plant-growth; Plant hormone can promote plant-growth.
Used polyacrylic molecular weight is between 800-8000, mineral acid is sulfuric acid, nitric acid, phosphoric acid or their mixture, wood vinegar is the wood vinegar that root, stem, leaf, seed, the kind skin heating pyrolyze of plant produced, wood vinegar can derive from softwood tree, can be deciduous tree, also can be draft.Plant hormone is Plant hormones regulators,gibberellins GA
3, indolylacetic acid or their mixture.
Advantage of the present invention is:
1, liquid form, convenient spraying is even.
2, chessom has water retaining function.
3, reduce the saline and alkaline of soil, reduce harmful salinity of soil.
4, improve the fertility of soil.
5, preparation simple, with low cost, be convenient to industrial continuous production.
6, nontoxic, harmless, pollution-free, be beneficial to environmental protection.
Embodiment:
The present invention will be further detailed with embodiment, but it is not limited to any or the similar example of these embodiment.
Embodiment 1:
By above-mentioned preparation method, make the saline-alkali soil conditioner of following mass percent:
Polyacrylic acid 20%, sulfuric acid 10%, phosphoric acid 2%, nitric acid 4%, wood vinegar 5%, indolylacetic acid 0.1%, water 58.9%.
