秸秆还田是培肥地力的主要措施,利用秸秆还田可以有效的提高土壤的有机质和氮、磷、钾及微量元素含量,增强土壤的保水保肥能力。秸秆还田可以增加土壤中微生物的活性,加速土壤熟化为有效释放土壤养分提供了有利条件,秸秆还田对后茬作物的生长和提高产量有重要的促进作用,事宜的还田数量与土壤特性和地力水平有关。
秸稈還田是培肥地力的主要措施,利用秸稈還田可以有效的提高土壤的有機質和氮、燐、鉀及微量元素含量,增彊土壤的保水保肥能力。秸稈還田可以增加土壤中微生物的活性,加速土壤熟化為有效釋放土壤養分提供瞭有利條件,秸稈還田對後茬作物的生長和提高產量有重要的促進作用,事宜的還田數量與土壤特性和地力水平有關。

Stalk return to field is the soil fertility of the main measures,the use of returning straw to can effec-tively improve the organic matter and nitrogen,phosphorus,potassium and trace element content of the soil, increase water retention capacity of the soil and fertilizer.Straw can increase soil microbial activity,accelerate ripening soil provide favorable conditions for the effective release of soil nutrients,crop straw after growth and increase production has an important role in promoting,but also the number of fields and soil characteristics matters and fertility levels.
