Saline-alkali wheat requires high yields and the use of chemical fertilizers is the key. Fertilizers are acidic, alkaline and neutral. Acidic and neutral fertilizers can be applied on saline land, and alkaline fertilizers can be avoided on saline land. Such as urea, ammonium bicarbonate, ammonium nitrate, etc. do not leave any impurities in the soil, will not increase soil salinity and alkalinity, suitable for application in the saline-alkali soil. Ammonium sulphate is a physiological acid fertilizer. After the ammonium in the fertilizer is absorbed by the wheat, the residual sulphate can reduce the alkalinity of the soil. It can also be applied in saline and alkali land. Alkaline fertilizers such as lime nitrogen and grass ash are not suitable for application on saline or alkali land. Sodium nitrate is a physiological alkaline fertilizer. When nitrate ions in fertilizers are absorbed by wheat, residual sodium not only increases soil salinity, but also increases soil alkalinity. Saline wheat is also suitable for ammonium chloride. To apply phosphate fertilizer to wheat in saline land, calcium superphosphate should be used. Applying calcium, magnesium and phosphate fertilizers will increase soil alkalinity. In addition, fertilization of wheat in saline-alkali land should be combined with the application of organic fertilizers, which can not only supplement various nutrients, but also help reduce the concentration of soil solution and reduce the salt-alkali hazards. Fertilizers should be applied in small quantities several times to avoid a sudden increase in the concentration of soil solution, affecting wheat absorption and growth. Ammonium nitrogen fertilizer is easy to cause ammonia volatilization on the saline-alkali soil, and it must be deeply buried.
