Description
Technical field
The present invention relates to planting technology fields, and in particular to a kind of method in more element improvement salt-soda soil.
Background technique
Salt-soda soil is a type of salt aggregation, refers to that salinity contained by soil the inside influences the normal life of crop
Long, according to UNESCO and food and agricultural organization's incomplete statistics, the area in whole world salt-soda soil is 9.5438 hundred million hectares,
Wherein China is 99,130,000 hectares.The formation of China's alkaline earth and alkali-affected soil, it is most of with Carbonates In Soil add up it is related,
Thus basicity is generally higher, and serious salt affected soil regional plant can hardly survive.The main reason for salinization of soil is
Due to, containing salt and alkali components such as potassium, sodium, calcium, the chloride of magnesium, sulfate, heavy carbonate, changing the physics and chemistry of soil in soil
Property causes soil quality to reduce, and plant growth is being suppressed in various degree, causes the significant underproduction in soil, the soil of large area
Earth resource cannot be utilized adequately.It is built up evaporating strong season salinity in upper soll layer, causes the pernicious of salt-soda soil and follow
Ring, farmland and water ecosystem are destroyed.Therefore, improvement, sustainable development, raising agriculture using salt-soda soil, to agricultural
People's income level, preserving the ecological environment etc. suffers from highly important meaning.
Many areas carry out alkaline land improving using hidden pipe salt discharge technology now, it is a kind of saline and alkaline using water conservancy method improvement
The method on ground, principle are according to the moisture-salt transport of " salt is with water come salt is walked with water " rule, being embedded in ground with foraminate pipeline
The salinity of upper soll layer is dissolved the technology drained in conjunction with irrigation leaching by 1~2 meter of depth below table.Hidden pipe salt discharge technology is
A kind of efficient technology for administering salt-soda soil of existing comparative maturity, can utilize the spy of " salt comes with water, and salt is gone with water " well
Point carries out effective administer to salt-soda soil.But hidden pipe salt discharge technology needs very high cost, needs the big machinery of special profession
Cooperated, very high manpower and material resources is needed to support in operational process, many medium-sized and small enterprises or family are cooperated for this point
It is very unfriendly for society, limit the threshold to alkaline land improving.
