Description

A kind of acid soil improving agent

Technical field

The present invention relates to a kind of soil conditioner, especially a kind of acid soil improving agent.

Background technology

Acid soil refers to pH<6.5 soil, acid soil accounts for the 40% of whole world cultivated area.China's acid soil Mainly include brick yellow earth, red soil, dry red soil and dark brown earth etc., its acid source mainly includes：C02 in rain water and air is dissolved in Water formation carbonic acid；Microorganism and plant root metabolite；Organic matter in application of organic fertilizers decomposes having for generation in soil Machine acid etc..

There are H+, A13+, MT12+ and Fe2+ of high concentration etc. in acid soil, plant can be had influence on after soil acidification To Nutrient uptake, the following aspects is mainly manifested in：1st, in acid soil, because aluminium ion has stronger adsorptivity Can, the negative electrical charge that it can be fought on colloid with exchangeable basic cations makes the base cation leaching loss such as calcium, magnesium, potassium, degree of base saturation Decline：2nd, because active iron in acid soil, aluminium increase phosphate radical are easy in connection, and infusible precipitate is formed, reduced P availability：3rd, the bacterium and actinomyces in soil（Such as nitrogen-fixing bacteria and cellulose-decomposing bacteria）It is adapted in neutral and micro- alkali Property environment in growth and breeding, activity is gradually reduced in acid soil, so as to influence decomposition and the soil fertility of organic matter, and true Bacterium occupies advantage in strongly acidic soil, causes plant disease serious；4th, acid soil colloid negative electrical charge is few, under degree of base saturation Drop, makes soil buffer performance weak：5th, due to the leaching loss of calcium, soil granular structure and aggregate are reduced, and cause soil physical property Deterioration, retain water and nutrients ability declines：6th, acid soil reduces soil nutrient availability, and the content of Al and other heavy metals is led to It is often all very high, murder by poisoning can also be formed to plant.

Improvement acid soil method is to apply quick lime in soil surface in production at present, is then mixed with topsoil soils, The shortcoming of this method is mainly：If quick lime apply it is uneven may directly contact plant gemma, influence emergence rate or not It can emerge, if directly being contacted with root system of plant, burn seedlings and rotten can be caused；Quick lime solubility is small, the shifting on soil profile Dynamic property is very slow, and a large amount of or chronic administration quick lime can cause soil hardening, while can also cause the elements such as soil calcium, potassium, magnesium to lose Tune causes crop failure；It is excessive to reduce the absolute content of soil moisture using quick lime, cause plant hydropenia, that is, generally The phenomenon for the lime " burn seedlings " being considered as；Quick lime is being mixed into soil initial stage, and soil pH index can be made to raise rapidly, destroys soil Biological character.

The content of the invention

It is an object of the present invention to provide a kind of acidic soil conditioner, improve the acid environment of soil, overcome simple administration The shortcoming and defect of quick lime, improves the yield and quality of agricultural product.

Technical scheme：A kind of acid soil improving agent, is made up of following components by quality proportioning：

40-80 parts of agstone；Ammonification humic acid 5-30 parts of powder of original；5-30 parts of powder of straw；5-10 parts of silica；Calcium magnesium phosphate 10-30 parts；1-5 parts of zeolite powder；0.2-1 parts of zinc oxide；0.2-1 parts of borax；0.05-0.2 parts of ammonium molybdate；

Above component is uniformly mixed.

Agstone is formed by lime stone is levigate, and the acidity ability of thinner sweetening of the soil is stronger, it can largely apply without The growth of crops can be influenceed；When soil aciditiy is bigger, its neutralising capacity is stronger；When soil is in neutral or alkalescence, that is, stop Neutralize, will not be neutralized as quick lime and white lime acutely, also will not be as quick lime and white lime because using excessive Soil is caused in alkalescence, agstone is the desirable feedstock that a kind of intelligence neutralizes acid soil；

Agstone is longer than lime and white lime lasting period；Quick lime and white lime are applied once, no matter soil ph, It is expired to fail, and agstone is applied once, is neutralized immediately when soil is in acidity, when soil is in neutral or alkalescence, stone Limestone flour is not neutralized, and is also retained in soil, will not be failed, and continues to play its effect when being left to soil souring；

Ammonification humic acid original powder, is formed by the former powder ammonification of ammoniacal liquor and humic acid, and its powder more former than humic acid is more soluble in water, farming Thing can more be absorbed；

The effect that ammonification humic acid original powder powder more former than humic acid integrates microelement fertilizer more preferably, replaces crop root part heavy metal ion Ability it is stronger, effectively prevent crops by Heavy Metal Pollution, it is also more effective to prevent crops from absorbing heavy metal, people is prevented indirectly Class is poisoned by heavy metal；

Powder of straw, is steamed with boiling water or boiled to soft, removed toxin and grease, borax zinc oxide, ammonium molybdate are mixed respectively, dry and Into；

The unprocessed powder of straw of powder of straw ratio for removing harmful components and grease is more easy to decompose, and is difficult to strive soil with crops during decomposition Oxygen and ammonia fertilizer in earth；

Micro- fertile powder of straw is mixed, is the micro- fertilizer of sustained release, micro- fertilizer is difficult injury crop seeds and root, than directly applying micro- fertilizer safety, Fertilizer efficiency is lasting.

The present invention can increase same pH value, when the PH of soil is low（PH<6.5）When, there is physiological disease in plant, and root becomes Black, not long new root, aluminium ion Fe⁺³Deng heavy metal meeting poisonous plant, Grain Growth Situation is obstructed, and leaf Huang, scab, short and small, sky occurs A series of consequences such as the heart, seed be small, have a strong impact on yield, quality.

When applying the acid soil improving agent, P in soil H values become slightly sour or neutral soil, are especially suitable for agriculture close to 7 Plant growth, plant root bleaches, and grows new root, and the yield and quality of agricultural product is significantly lifted.

Embodiment

Embodiment 1
