Abstract

The invention discloses a method for planting soybeans in medium saline and alkaline land. The method includes the following steps of soil preparation, modifier addition, seed sowing and fertilization management. The salt and alkali content in the medium saline and alkaline land is effectively decreased through modifier addition so that the saline and alkaline land can meet the growth requirements of soybeans. All components in added modifier can play a role in restraining soil salt increase, lowering the soil alkali content and improving the physical and chemical properties of soil while playing roles of themselves. By means of the added modifier, microelements and humic acid organic nutritional ingredients in the saline and alkaline land can be improved, nutrient of soil is improved, and therefore the soil fertility is comprehensively improved, and growth of plants is promoted; through cooperation of fertilizer dressing in the later period, the content of N, P and K in soil is increased, the planted soybeans can be good in growth vigor, and the effect of increasing yield 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 soybeans in moderately 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, moderate saline-alkali land and heavy saline-alkali land. Light saline-alkali lan...
