70%, become facility cultivation area in the world and its maximum country of total output.However it cultivates and grows rapidly with current facility
Incompatible is that there is no a set of Soil and fertilizer management measure suitable therewith so far in Greenhouse Cropping Systems.Due to greenhouse,
Soil under the cultivation conditions such as greenhouse lacks rainwater elution, and temperature, humidity, aeration status and water and fertilizer management etc. are planted with open country
Training has bigger difference, and facility cultivation is chronically at the production status of high intensive, high multiple crop index, high rate of fertilizer again in addition
Under, special ecological environment results in the Soil Secondary of national 90% or more facility cultivation with unreasonable water and fertilizer management measure
The generation of many production problems such as salination, nutrient imbalance, soil acidification.Wherein the most outstanding is Soil Secondary salt marsh
Change, the normal growth of its not only direct damage to crops, but also easily cause other associated production problems, such as: soil is harder, hair
Plate is not easy farming；Secondly as extraneous salt concentration is excessively high, cause crop that cannot absorb moisture and nutrient well in seedling stage,
Slow seedling is slow when transplanting seedlings, and death rate is high, and Crop development is slow, easily susceptible, and then yield is caused to decline, and quality reduces.
Currently, the control measure of soil secondary salinization generally proposes: applying organic manure, reduce applying quantity of chemical fertilizer,
Soil testing and fertilizer recommendation, flood irrigation, closed drainage, seasonality are taken off the measures such as canopy, soil conditioner, sustained-controll-release fertiliser, but in recent years, are ground
Study carefully and these control measures must be used scientifically using discovery, for applying organic manure, blindly application can run counter to desire, must
It must consider the amount of application and application type of organic fertilizer.Meanwhile these measures high investment itself, effect difficulty reach desirable.
Therefore, soil in protected field secondary salinization has become common problem in China's facility cultivation, and seriously constrains and set
Apply the sustainable development of agricultural.
