Abstract

The invention provides an acidic soil conditioner which is composed of the following components in parts by weight: 5-10 parts of ferrisodium ethylenediamine tetraacetate, 5-10 parts of bentonite, 5-15 parts of sodium octaborate tetrahydrate, 30-50 parts of fly ash, 15-25 parts of manure, 15-25 parts of activated sludge, 15-25 parts of organic matter, 0.5-1.5 parts of sodium lactate, 10-20 parts of potassium magnesium sulfate fertilizer and 15-25 parts of bamboo vinegar solution. The raw materials follow the environmental protection principle, thereby changing wastes into valuable substances, fully utilizing the waste resources and avoiding environmental pollution. By using the reasonable proportioning, various raw materials are synergistic, thereby regulating the soil pH, increasing the organic matter content of soil, improving the soil structure, balancing the fertilizer and water retaining capacity of the soil, obviously lowering the heavy metals and harmful elements in the soil, promoting the plant growth and development, enhancing the disease resistance of plants, and improving the crop yield and mouthfeel.

Description

A kind of acid soil improving agent

Technical field

The present invention relates to technical field of land improvement, be specifically related to a kind of acid soil improving agent.

Background technology

Soil be crops rely growth material base, the soil organism number, soil fertilizer water holding capacity strong Weak, soil sticks quality of the power of principal characteristic, soil aeration ability etc. and the growth of plant is had decisive role.In long-term agriculture During industry produces, to the demand of grain and pursue grain yield in order to meet ever-increasing population, along with the rise of chemical products, The a large amount of unreasonable use chemical fertilizer of people and pesticide, the residual hazard composition such as substantial amounts of heavy metal, hormone ultimately results in soil quality Deteriorate, the content of organic matter reduces, soil fertilizer water holding capacity weakens, soil sticks that principal characteristic is extremely strong, soil aeration ability and soil Earth hardens, the reduction of soil internal pH, the minimizing of slag cation, toxic metal ions activity increase etc. are unfavorable for crop growth Consequence, have a strong impact on crops normal growth and yield and reduce the mouthfeel of food, healthy to the mankind brings Harm.

In order to improve Soil structure, improving soil fertility, various soil conditioners continue to bring out, but current modifying agent There are still some shortcomings, need improvements: the improvement cycle is long, and the persistent period is too short；Add chemical fertilizer, improved effect Difference；Complicated component, cost is high, promotes limited；Each proportioning raw materials is unreasonable, causes polluting further and destroying soil；Make With single, specific aim is the strongest.

Therefore exploitation one can be effectively improved soil organic matter content, regulate soil pH value, improves Soil structure, strengthens soil Before earth fertilizer conservation water holding capacity, the soil conditioner of the reasonable mixture ratio changing toxic metals existing forms are highly desirable to and promote Scape.

Summary of the invention

It is an object of the invention to, it is provided that one can be effectively improved soil organic matter content, regulation soil pH value, improve soil Earth structure, strengthens the acid soil improving agent of the reasonable mixture ratio of soil fertilizer water holding capacity, change toxic metals existing forms.

For solving above-mentioned technical problem, it is achieved above-mentioned purpose, technical scheme is as follows:

A kind of acid soil improving agent of the present invention, is made up of the component of following weight portion: EDTA-Fe Sodium 5～10 parts, bentonite 5～10 parts, four water eight sodium borate 5～15 parts, flyash 30～50 parts, feces 15～25 parts, activity Mud 15～25 parts, organic 15～25 parts, sodium lactate 0.5～1.5 parts, potash magnesium sulphate fertilizer 10～20 parts, Bamboo vinegar solution 15～25 Part.

Preferably, a kind of acid soil improving agent, it is made up of the component of following weight portion: sodium iron ethylenediaminetetraacetate 7～8 Part, bentonite 7～9 parts, four water eight sodium borate 8～12 parts, flyash 35～45 parts, feces 18～22 parts, activated sludge 18～ 22 parts, organic 18～22 parts, sodium lactate 0.8～1.2 parts, potash magnesium sulphate fertilizer 12～18 parts, Bamboo vinegar solution 17～23 parts.

Preferably, a kind of acid soil improving agent, it is made up of the component of following weight portion: sodium iron ethylenediaminetetraacetate 8 parts, Bentonite 8 parts, four water eight sodium borate 10 parts, 40 parts of flyash, 20 parts of feces, activated sludge 20 parts, organic 20 parts, sodium lactate 1 part, potash magnesium sulphate fertilizer 15 parts, Bamboo vinegar solution 20 parts.

Preferably, described flyash particle diameter is 300-400 mesh, water content 8%-10%.

Preferably, described feces be human faecal mass, cattle manure just, the mixture of swine excrement.

Preferably, described organic matter is the fermented rear formation of fruit/vegetable waste, and the content of organic matter is 6-12%, pH 6.8-7.2。

Beneficial effect: the principle of environmental protection followed by raw material of the present invention, turns waste into wealth, and makes full use of waste resource, it is to avoid environment Pollute, by rational proportion, make each raw material coordinate potentiation, it is achieved that regulation soil pH, increase soil organic matter content, improvement soil Earth structure, balanced soil fertilizer conservation water holding capacity, significantly reduce heavy metal-polluted soil and harmful element, promotion plant growing and growth, Strengthen disease resistance of plant, the yield improving crops and eating mouth feel.
