Improver applied to crops in saline-alkali soil

Abstract

The invention discloses an improver applied to crops in saline-alkali soil. The improver comprises the following components in parts by mass: 50-70 parts of a fertilizer, 4-8 parts of a microbial agent, 10-20 parts of straw charcoal, 10-20 parts of an acidity regulator, 10-15 parts of a blocking agent, 1-3 parts of a settling agent and 2-6 parts of a sodium ion adsorbent. The improver is common incomponents, easy to prepare, low in cost and capable of efficiently improving saline-alkali soil and shortening the soil improvement period.

Description

technical field [0001] The invention belongs to the technical field of land improvement, and in particular relates to an improving agent applied to crops in 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 statistics, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares is in my country. 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] For saline-alkali land, methods such as washing salt, leveling the land, timely harrowing, and adding organic fertilizers are often used. However, these methods have many defects, such as high cost and long cycle. Due to the continuous increase o...
