Abstract

The invention discloses a method for planting corns on a severe saline-alkali land, which comprises following steps: preparing soil, adding improving agent, sowing, managing fertilizing. By adopting the method provided herein, the salt content in the severe saline-alkali land and the soil physical and chemical properties can be improved effectively; the micro elements and the humus acid organic nutrient ingredients in the saline-alkali land are improved; and the nutrient in the soil is increased, thus comprehensively improving the soil fertility, promoting the crop to grow and optimizing the growth environment of the crops; and further the planted corn has good growth and the effect of improving production is realized.

Description

technical field [0001] The invention relates to the technical field of planting in saline-alkali land, in particular to a method for planting corn 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 th...
