First, increase the application of organic fertilizer
It is best to apply organic fertilizer with high cellulose and carbon to nitrogen ratio to enhance soil buffer capacity, prevent salt accumulation and delay soil salinization.
Second, deep ploughing soil
After the vegetables are harvested, turn the soil deep, turn the salt-rich topsoil to the lower layer, and turn the lower layer of soil with relatively less salt to the top to reduce salt damage.
Third, dissolved salt wash salt
After the harvest of summer cooked vegetables, use the gap to remove the film, and after dozens of days of sun and rain in the rainy season, the effect of soil salinization can be eliminated. Or in the hot season, after the flooding of large water, cover the film on the ground, so that the temperature under the film rises, not only can wash the salt, but also can be sterilized.
Fourth, deep application of base fertilizer and fattening
Use chemical fertilizer as the base fertilizer to apply deep, and try to "eat less and eat more" when topdressing. It is best to mix the chemical fertilizer with the organic fertilizer and apply it to the ground, and then plough up. It is generally difficult to apply deep fertilizer. The amount of fertilizer should be strictly controlled. Do not apply too much fertilizer at one time, otherwise the soil solution concentration will be increased.
Fifth, the ground cover with the ground film for ground coverage, has a significant effect on the suppression of soil surface salt.
