Description

A kind of integrated approach of soil conditioning and reparation
Technical field
The present invention relates to the integrated approach of a kind of soil conditioning and reparation, in particular to a kind of not influence soil Crop Species The integrated approach for planting and being improved soil and repaired under the premise of capable of improving crop quality belongs to soil restoring technology neck Domain.
Background technique
Soil refers to one layer of loose substance of earth surface, by various particulate minerals, organic substance, moisture, sky The composition such as gas, microorganism, can growing plant.Soil minerals, animals and plants as made of rock weathering, microorganism residuum decomposition produce Raw organic matter, geobiont (solid matter) and moisture (liquid phase substance), air (gaseous substance), the humus etc. of oxidation Composition.Soil is the core dielectric of environment, is indispensable regenerated resources and the mankind and the weight that many biologies are depended on for existence Want ambient condition.The quality of soil environment directly affects the quality of agricultural and sideline product and then influences the health of the mankind.
As a large amount of unreasonable application of chemical fertilizer and high-quality organic fertilizer application are insufficient, get over the accumulation of soil intermediate ion Come more, organic matter is fewer and fewer, causes soil acidification serious, to cause problems.Such as soil hardening is aggravated, make root System's stretching, extension is difficult, and rooting ability is weak, and slow seedling is difficult, grown-ups and children tree easy to form, old runt seedling, and the bad absorption function of root system development reduces, Growing way is weak, and yield reduces;Pesticide waste is aggravated, plant growing way weakens, and disease resistance reduces, easily by disease infestation, it has to increase It is affixed by dose;Make the reduction of part middle and trace element absorption rate, investment is caused to increase, benefit is greatly lowered;Seek crop Support bad, nutritional deficiency disease is serious, such as apple bitter pit, pears iron head disease, mango black heart frequently occur;Cause soil beneficial to micro- life Species group variation, organisms growth become smaller, and growth and breeding speed reduces, and such as decomposes main micro- life of organic matter and its protein Species group bacillus, actinomyces, methane pole hair bacillus and related fungi reduce, and influence the benign cycle of nutrient, Cause the agriculture underproduction;Heavy metal in soil content is caused to increase, activity improves, so that it is very big to there is the crop of grown on soil Edible safety.Therefore, green, health, environmental protection are being pursued instantly, is researching and developing a kind of efficient soil conditioning and reparation side Method is able to satisfy and continues the drawbacks of plant growth is avoided that the methods of certain physics, chemistry, biology, electrolysis again, such as changes Method easily causes secondary pollution, and electrolysis method handles that the time is long, influences soil ecology, and bioanalysis rate is slow, the period is long and to soil Environmental requirement is stringent etc..
Summary of the invention
