秸秆还田五注意一、注意秸秆的翻埋量。秸秆直接还田时翻埋量不宜过多,一般每亩500公斤以下,否则不仅会影响秸秆腐解的速度,而且秸秆腐解过程中产生的各种有机酸过多,对作物根系还有损害作用。二、注意加强水分管理。土壤水分状况是决定秸秆腐解速度的重要因素,所以秸秆直接还 Note five straw a, pay attention to the volume of straw burial. Straw directly into the field when the amount of turning over should not be too much, usually less than 500 kilograms per mu, otherwise it will not only affect the speed of straw decomposition, and straw decomposition of organic acids produced in too many, there is damage to the crop roots effect. Second, pay attention to strengthen water management. Soil moisture status is an important factor in determining the rate of decomposition of straw, so straw direct
