Description
Technical field
The invention provides a kind of strand sandy soil saline-alkali land soil conditioner and the application in Sorghum sudanense plantation thereof, belong to technical field of land improvement.
Background technology
The basic reason that saline-alkali soil is formed is that water regime is bad, so at the improvement initial stage, emphasis should be placed on and improve above water regime of soil.The principal feature in saltings is containing more water-soluble salt or alkaline matter, improvement saltings principle be will salt discharge, every salt, anti-salt while, positive fertilizing soil, major measure has:
1, draining
To the saline and alkaline plot of hypsography low-lying.By drainage trenching, discharge the surface water and can take away part soil salt.
2, washing salinity by irrigation
According to the rule of " salt comes with water, and salt goes with water ", water is poured in ground, forms the water layer of certain depth on ground, the salinity in soil is fully dissolved, then drain from waterways the salinity dissolved.Thus reduce the saltiness of soil.
3, soil moved in improve the original pressure alkali
Soil moved in improve the original is exactly soil removal and replacement, and soil moved in improve the original can improve the physical properties in saltings, has the effect pressing down salt, drench salt, press alkali and increase soil fertility, soil salt content can be made to be reduced to the degree of unlikely damage to crops growth.
Existing saline and alkali land improvement method, has the following disadvantages: (1) effectively can not reduce the pH of soil, basicity and saltiness; (2) prior art improvement soil after, soil with organic matter content and available nitrogen content not high; (3) water holding capacity of soil is few.
