Description
Technical field
The present invention relates to a kind of root control salt method using haydite filter layer and answering in salt-soda soil Melia azedarach L. is planted thereof
With, belong to agricultural use technical field.
Background technology
Current China water, soil resource owning amount, only can guarantee that 500,000,000 tons of grain production capacity, can not meet far away population day
The great demand that benefit increases.Meanwhile, China's energy scarcity contradiction is increasingly sharp-pointed, and biomass energy development must ensure " grain
Safety " premise.The Coastal beach of nearly more than 4,000 ten thousand mu of all kinds of gross areas that China has at present is the standby soil that China is important
Ground resource, Coastal beach saline-alkali soil develops and is possible not only to provide food source, also can become the important salt-tolerant plants such as the energy
Production carrier.
At present, in terms of utilizing beach saline-alkali ground developing agricultural plantation, how to control crop root zone and do not gather too
Many salinities, maintaining while topsoil soils salt balance saving water resource and promoting soil fertility and become restriction beach area agricultural
The realistic problem of sustainable development.
For the transformation in salt-soda soil, the mankind have done many significant explorations and research, mainly have following several method: 1,
Chemical amendments, i.e. adds substantial amounts of chemical substance, as Gypsum Fibrosum, ardealite, acidic materials and water-retaining agent etc. are changed to salt-soda soil
Learn, to improve the effective ingredient in salt-soda soil；2, biological method, mainly by plantation alkali resistance plant, manually sets up hay
Layer etc.；3, physical method, main by scarifying soil layer, change the physical arrangement of saline and alkaline layer.
The renovation technique in existing salt-soda soil controls crop root zone do not gather too many salinity and have the disadvantage in that
1, poor to the physicochemical property improved effect of soil in salt-soda soil；
2, in soil, salinity can not control very well in the range of plant suitable growth；
3, the concentration regulating effect of ion each to soil in salt-soda soil is poor.
Haydite, as the term suggests, it is simply that the granule of ceramic.The external appearance characteristic rounded or oval-shaped ball of major part of haydite,
But having some imitative rubble haydites is not circular or oval-shaped ball yet, and in irregular rubble shape.Haydite shape is different because of technique
And it is different.Its surface is one layer of hard shell, and this layer of shell is ceramic or enamel, has water proof and protects gas effect, and composes
Give the intensity that haydite is higher.The appearance color of haydite is different and different with technique because of the raw material used.The color of roasting haydite
Being mostly kermesinus, ember, also having some special kinds is lark, grey black, canescence, cinerous etc..
Summary of the invention
The present invention solves the deficiency that prior art exists, it is provided that a kind of root control salt method using haydite filter layer and
Its application in salt-soda soil Melia azedarach L. is planted, to realize following goal of the invention:
(1) physicochemical property of soil in salt-soda soil is had good by the root control salt method containing filter layer that the present invention provides
Improved effect；
(2) salinity in soil can be controlled to fit at long-term cropping by the root control salt method containing filter layer that the present invention provides
In the range of preferably growing；
