Description
Technical field
The present invention relates to a kind of continuous cropping soil processing method, belong to technical field of land improvement.
Background technology
Soil is the most basic means of production of the mankind, is material base for the survival of mankind.In China, land resource is not
But it is very limited, moreover, because the factors of soil formation or human factor cause to have the soil of obstruction factor significant proportion to be also present, wherein
Including corroding, quality is bad, structure or tilth are poor, saline and alkaline, acidifying, noxious material pollution, exists in soil and hinders root system of plant
The bad soil layer of growth, soil moisture are excessive or deficiency, fertility are low or nutrient is unbalance etc..
Vegetable production in green house is excessive to apply chemical fertilizer or partially applying due to continuously planting same or same section crop
Fertilizer, soil harmful microorganism is caused to accumulate, soil nutrient is unbalanced, fertility declines, vegetable insect disease is serious, yield reduction, product
The problems such as matter declines, so that facility plastic greenhouse continuous cropping obstacle phenomenon is universal, seriously governs the sustainable development of industrialized agriculture.Institute
So that solve Soil-sickness Problem has turned into the upper a great problem urgently to be resolved hurrily of vegetables production.
With the modern development for strengthening facility plastic greenhouse vegetables, greenhouse continuous cropping obstacle is on the rise, it has also become limitation canopy room is steady
Production increases income and an important factor for sustainable development, including organic fertilizers input deficiency, abuses chemical nitrogen fertilizer and causes Secondary salinization
Change serious greenhouse vegetables continuous cropping obstacle.Because greenhouse facility special environment condition and fertilising it is unreasonable, cause plastic shed soil
There are the soil continuous cropping obstacle problems such as salinization, acidifying and the accumulation of N, P chemical element, had a strong impact on the hair of booth vegetable production
Exhibition and the flavor quality of product, turn into the principal element for restricting new district Facility Agriculture Development.
Therefore some the soil continuous cropping obstacle factors occurred in being cultivated to greenhouse facility are analyzed and for its improvement
Technology is studied and soil improvement, for reducing the loss brought due to soil continuous cropping obstacle problem, improves booth vegetable and plants
Training level has extremely important value.
The content of the invention
The technical problems to be solved by the invention：The problem of soil continuous cropping obstacle occurred in being cultivated for greenhouse facility,
The invention provides a kind of continuous cropping soil processing method.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of continuous cropping soil processing method, it is characterised in that concretely comprise the following steps：
（1）Continuous cropping soil is routed up into rear high temperature steam treatment；
（2）Modifying agent mixed processing is added into continuous cropping soil.
The high temperature steam treatment is to sweep 1~5min, steam temperature with high-temperature vapor spray after continuous cropping soil is routed up
For 90~100 DEG C.
The modifying agent processing is to add modifying agent by 100~200g/kg to mix 1~5min in continuous cropping soil.
The modifying agent forms for following weight parts raw material：10~50 parts of rhizobia fertilizers, 50~100 parts of active carriers, 10
~30 parts of EM bacteria agents are mixed to prepare.
The rhizobia fertilizer is following weight parts raw material：20~30 parts of flat mushroom bacteria stick wasted powders, 10~12 parts of guanites
Powder, 10~12 parts of wood chips, 8~10 parts of rice brans, 1~2 part of humic acid magnesium, 1~2 part of calcium humate, 3~5 parts of soybean nodulations, 8
~10 parts of mass fractions are 10% glucose solution, and fermentation reactor system is made for 20~30 days at 36~38 DEG C.
The active carrier forms for following weight parts raw material：10~30 parts of dolomites, 5~6 parts of flyash, 1.0~1.5
Part vermiculite, 0.3~0.6 part of diatomite, 10~20 parts of carbonization rice husk ashes.
The carbonization rice husk ash is the rice husk handled through CO 2 supercritical, is placed in Muffle furnace, under nitrogen atmosphere,
350~360 DEG C, 3~4h of isothermal holding are heated to, then is made with 10~12min of 550W microwave irradiations.
The EM bacteria agent is the hundred precious EM bacterium solutions of benefit.
The method have the benefit that：
The present invention kills pernicious bacteria in continuous cropping soil by high temperature steam treatment, recycle guanite, flat mushroom bacteria stick waste material,
Wood chip, soybean nodulation etc. are fermented, and by activating nutritional ingredient in rihizobium japonicum growth course, rhizobia fertilizer is made, living
Change N, P chemical element accumulated in balanced soil, recycle activated carbon and the compound dolomite of silica, flyash in rice husk
Deng, improve the physical behavior of fertilizer, reduce the loss of fertilizer nutrient, improve the utilization rate of fertilizer, strengthen the shock-absorbing capacity of soil,
Harmful element in soil is adsorbed, repairing heavy metal in soil pollution, soil salinity characters, acidifying is reduced, overcomes soil continuous cropping obstacle.
