Abstract
The invention relates to the technical field of agricultural environment conservation and repair, in particular to a composite soil conditioner. The composition soil conditioner is prepared from, by weight, 30-60 parts of limestone flour, 25-50 parts of decomposed straw, 10-30 parts of sepiolite and 1-10 parts of K2HPO4. The composite soil conditioner comprises four effective ingredients, the pH of soil can be stably kept at a certain level, and particularly, the pH of acid soil can be effectively adjusted; phosphate radical and humic acid in the conditioner can effectively chelate and deposit available cadmium in soil, and pollution brought by cadmium metal to soil and crops is reduced.
Description
Technical field
The present invention relates to agricultural environment child care and recovery technique field, be specifically related to a kind of compound
Soil conditioner.
Background technology
Soil acidification is a kind of form of expression of soil degradation, and soil acidification the most still soil is fertile
The major reason that power declines, is also the key factor of restriction sustainable development of agricultural production.
According to statistics, from the eighties in last century so far, China's soil acidification situation is increasingly severe, acid
The land area changed has expanded more than the 40% of China's cultivated area to, and often has into
The situation that sheet occurs, particularly at south China, due to the slant acidity of soil own, rainwater is many,
Soil acidification phenomenon is more serious.
Soil acidification can cause the activation of the heavy metals such as aluminum, manganese, chromium, cadmium, thus affects
The growth of plant, as the phenomenon such as poisoning by aluminum, manganese poisoning occurs, and the heavy metal quilt activated
After Crop accumulation, by food chain harmful to human and the health of animal body.
At present, acid ground Heavy Metal Pollution Control has the multiple sides such as physics, chemistry, biology
Method, but conventional be that to use soil conditioner absorption heavy metal-passivated, because it is compared to other
Method has the feature of low cost instant effect.Using soil conditioner is one not only economy but also side
Just method, it can improve soil physical and chemical property, strengthen soil soil conservation water holding capacity, increasing
Strong Trace Elements in Soil effectiveness；Can also improve simultaneously Soil Microorganism and enzymatic activity,
Suppression sex pheromone, enhancing plant resistance to environment stress etc..But in various soil conditioners, people
The high cost of macromolecular compound and its latency environment pollution risk existed of work synthesis and
Limit its extensive application；There is improved effect comprehensively or have not in single soil conditioner
The weak points such as the negative effect with degree.
Summary of the invention
The deficiency existed for soil conditioner of the prior art, the present invention provides a kind of compound
