随着人们生态环境保护意识的提高,及秸秆禁烧令的出台,作物秸秆还田和保护性耕作普遍应用于农业生产。农作物秸秆还田具有增加土壤有机质(年平均增加0.07%),提高土壤养分含量,改善土壤结构,提高蓄水保墒能力等多项有利作用,利于作物生长提高产量,可亩增产9.6kg以上。保护性耕作具有节约生产成本,每亩节省农机作业费50元以上,达到节支增效的作用。保护性耕作还具有节约水资源、保持水土、节约能源、防风固沙、减少沙尘污染、保护生态环境等间接的生态效益。
With the improvement of people’s consciousness of ecological environment protection and the banning of straw burning, crop straw returning and conservation tillage are commonly used in agricultural production. Crop straw returning has many beneficial effects such as increasing soil organic matter (annual average increase 0.07%), increasing soil nutrient content, improving soil structure, improving water storage and soil moisture retention, and is beneficial to crop growth and yield increase, yielding 9.6kg or more. Conservation tillage saves production costs, saving farm machinery operating costs per acre more than 50 yuan, to save energy and increase efficiency. Conservation tillage also has the indirect ecological benefits of conserving water resources, preserving water and soil, saving energy, fixing wind and sand, reducing dust pollution, and protecting the ecological environment.
