Alkali land cotton open field direct seeding agent and application method thereof

Abstract

The invention relates to an alkali land cotton open field direct seeding agent and an application method thereof. The agent is mainly formed by mixing of 8-16 parts by weight of powdery cationic polyacrylamide, 50-70 parts by weight of starch grafted potassium polyacrylate, 6-14 parts by weight of a bactericide, and 14-22 parts by weight of gypsum powder. During land preparation before cotton seeding, the agent is evenly sprayed into the cotton field and mixed uniformly. The alkali land cotton open field direct seeding agent provided by the invention has the advantages of sufficient raw materials, simple manufacturing process, convenient use, environmental protection and safety, and after application to alkali land cotton open field direct seeding, can effectively solve the problems of cotton field hardening after raining and undesirable seedling emergence, prevent seedling diseases, and restrain water evaporation, thus guaranteeing even, full and robust cotton seedlings.

Description

technical field [0001] The invention belongs to the technical field of agricultural crop planting, and in particular relates to an agent for direct direct seeding of cotton in alkaline soil and an application method thereof. Background technique [0002] Cotton in saline-alkali land is usually cultivated by mulching with plastic film. The plastic film used is polyethylene film, and the recovery rate is about 50%. The plastic film left in the cotton field can not be decomposed for more than 200 years, seriously polluting the cotton field. However, if it is directly cultivated in the open field, there will be problems that the cotton field will harden after rain at the emergence stage of cotton sowing, and it will be difficult to emerge. Contents of the invention [0003] In order to solve the problems of hardening of cotton fields and difficult emergence of cotton seedlings after rain in the open field direct seeding stage of cotton, the present invention provides a powdery...

Problems solved by technology

[0003] In order to solve the problems of hardening of cotton fields and difficult emergence of cotton seedlings after rain in the seedling stage of direct seeding in the open field, the present invention provides a powdery mixture, that is, an agent for direct direct seeding of cotton in alkaline fields, and its application method, which is evenly sprinkled into the cotton field before sowing. Mixing soil in the cotton field can effectively solve the problems of hardening and poor seedling emergence in the cotton field after rain, and inhibit water evaporation
