Background
The saline-alkali soil is an important resource of usable cultivated land in China, and with increasingly sharp contradictions between land degradation, resource shortage and ecological deterioration, people pay more and more attention to the development and utilization of the saline-alkali soil. At present, the measures for improving the saline-alkali soil mainly comprise engineering, biological, chemical and other measures. The engineering measure investment is large; the investment of biological measures is small, but the effect is slow; chemical measures such as adding gypsum, phosphogypsum, vinegar residue and the like have certain effects and low cost, but the application amount is large, and the long-term application is not suitable. In addition, due to the special physicochemical properties of the saline-alkali soil, such as high pH value, poor permeability, high soil salinity and high alkalinity, soil humus is leached, and the soil structure is damaged; the urea applied into the soil has high hydrolysis speed and is easy to cause ammonia volatilization loss; the applied phosphate fertilizer is easy to be fixed, and the effectiveness of the phosphate fertilizer is reduced; in addition, saline-alkali soil contains excessive soluble salts, so that the osmotic pressure of the soil solution is high, physiological drought of plants is caused, the normal growth of the plants is influenced, and the crop yield is low. Therefore, the improvement and the fertilization are carried out simultaneously, namely the physical and chemical properties of the soil can be improved, the salt content of the soil is reduced, the permeability of the soil is improved, the utilization rate of the applied fertilizer is improved, the harm caused by overlarge fertilizing amount is reduced, and the low-yield saline-alkali soil is improved into the normally produced soil so as to improve the crop yield. The beet is an important sugar crop in northern China, has higher salt resistance, and can be harvested better by only strengthening soil preparation, scientifically and reasonably applying fertilizer, improving seedling protection rate, finely managing and other measures when being planted in light and medium saline-alkali lands.
Beet is planted in a crop area in the north of China, generally by adopting a seedling transplanting method, the growth link of the beet in the seedling stage without salt and alkali resistance is carried out in a seedling bed of non-saline and alkaline land, the beet is transplanted into a field block of the saline and alkaline land after growing into seedlings, the vitality of the beet growing into the seedlings is vigorous, and the beet has the salt and alkali resistance. However, in order to improve the fertilizer efficiency and increase the yield and sugar content of sugar beets, it is necessary to study a special fertilizer suitable for planting sugar beets in saline-alkali soil.
