Description
Technical field
The invention belongs to technical field of land improvement, in particular to a kind of hardened soil improvement method and its application.
Background technology
Soil is the environment that crops depend on for existence, in soil nutrient number and soil gas permeability power to plant
Growth is even more important.As countries in the world are to the pay attention to day by day of agricultural sustainable development, to the sustainable of the production capacity of soil
More stringent requirements are proposed for property, especially has a large population, under the severe situation for grain security of ploughing less, face, fully ensures soil
The capability of sustainable development be particularly important.And soil hardening is one of important behaviour of soil degradation, currently, soil hardening
Have become the big obstacle for hindering China's agricultural further to develop.Soil hardening refers to upper soll layer due to a lack of organic matter, structure
It is bad, pour water or the external cause actions lower structures such as rainfall destroy, earth material dispersion, and so that native face is become by cohesion force effect after drying
Firmly, the phenomenon that being unsuitable for the growths such as crops.
During agricultural modernization is greatly developed, because chemical fertilizer, plastic products are used for a long time for many years, using inappropriate
Mechanical cultivation etc. so that soil property becomes hard hardened, causes soll layer structure bad, causes liquid manure to be lost in serious so that soil
Earth shortage organic matter, microbial activity are low, influence the formation of soil aggregate structure, cause the acid-base property of soil excessive or too small,
Soil hardening, soil fertility is caused to decline.Further, the hardened soil on the ground, after seedling emergence, seedling take root it is very shallow, no
The moisture and nutrient in soil can be fully absorbed, so that crop is easy lodging, cause Severe Reduction；And the grain matter of gained
Measure bad, moisture is also high, is not easy to store, and the price sold is low, and then cause planting cost to increase, yield declines, yield reduces
Multiple risks.
Currently, being directed to soil hardening problem, solution mainly has several：First, deep ploughing, sow seed when
It waits, deep shoveling, arable land roll up the soil of field deep layer to come, the soil of shallow-layer is turned down, and seed is enable to be crouched deeply in soil
In, there is more fully nutrient；But the effect of this method is more of short duration and inconvenient, heavy workload, time cost are higher, also
Increase the soil erosion and the native hardened risk of table.Second is that using animal wastes such as chicken manure sheep manure cow dung pig manures or using micro- life
Object microbial inoculum helps to promote soil fertility and increases the substance of organic matter, this method using other soil conditioners etc.
The case where being likely to occur heavy metals exceeding standard and antibiotic residue, and it is relatively slow to be taken effect using soil conditioner, for originally sternly
The hardened soil of weight, existing soil conditioner can not improve the upgrowth situation of crop at once.Third, sowing green manure, then green
Fertilizer-plant turns over the method into soil, and this method can increase many costs of labor, for example needs to buy green manure seed, to green
Sowing, maintenance of fertilizer-plant etc., whole process trivial operations, high labor cost.
In consideration of it, special propose the present invention.
