Abstract

The invention discloses a method for planting sorghums in strongly saline-alkali soil. The method comprises the following steps: soil preparation, ameliorant addition, sowing, and fertilization management. According to the method, the saline-alkali content and physical and chemical properties of the strongly saline-alkali soil can be effectively improved, trace elements and humic acid organic nutritional ingredients in the saline-alkali soil are increased, and nutrients in the soil are increased, and therefore, the soil fertility is improved overall, the crop growth is promoted, and the environment of crop growth is optimized, further, planted sorghums grow well, and an effect of production increasing can be achieved.

Description

technical field [0001] The invention relates to the technical field of planting in saline-alkali land, in particular to a method for planting sorghum in severe saline-alkali land. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. [0003] In the process of utilization of saline-alkali land, simply put, it can be divided into light saline-alkali land, severe saline-alkali land and heavy saline-alkali land. Light saline-alkali land means...
