Increase the use of organic fertilizer and bio-fertilizer greenhouse fertilizers should increase the amount of organic fertilizer, and apply a certain amount of biological fertilizer, while deep-landing, improve soil structure, cut off the soil capillary, prevent surface soil salt accumulation. Deep-turning land is also conducive to improving soil permeability, increasing ground temperature, accelerating the conversion and absorption of organic fertilizers, increasing the activity of biological fertilizers, facilitating the lateral root elongation of vegetable plants, enhancing the ability of roots to absorb nutrients and moisture, and increasing the salt resistance of plants. .
Rational application of chemical fertilizers A single fertilization is one of the main reasons for the increase of soil salinity, so it is necessary to avoid using the same chemical fertilizer in greenhouses. Use as little or no sulfides and chlorides as possible. Use urea, ammonium nitrate, ammonium phosphate, high-efficiency compound fertilizer, and granular fertilizer. Do not use excessive amounts at one time. Fertilizers should be planted or planted at the time of colonization and applied at a depth of 12 to 15 cm to avoid appearance. Fertilizers and organic fertilizers can be applied alternately during growth. Fertilization depends on the days, places of origin, and seedlings.
