通过田间小区试验研究麦秸和玉米秸等农作物秸秆还田及应用秸秆速腐剂还田秸秆对当季小麦产量的影响。结果表明 ,施用未经处理的作物秸杆对当季小麦产量影响不大。施麦秸量为 3 0 0 0和 6 0 0 0kg/hm2 时 ,当季小麦产量分别为对照的92 .8%和 96 .0 %,减产 7.16 %和 4.0 0 %,减产不显著。用玉米秸秆代替麦秸时 ,小麦产量为对照的 99.1%和 10 3 .2 %,与对照产量持平或略有增加。施用秸秆速腐剂后 ,小麦产量相对提高 3 .6 0 %和 1.45 %,是不施秸秆的 (对照 ) 99.5 %和 10 3 .2 %。玉米秸秆较麦秸腐解快 ,效果好 ,粉碎后可直接还田
Field cropland experiments were conducted to study the effects of straw and corn stalks on crop straw returning and the application of straw vetiver to soil straw yield on the seasonal wheat yield. The results show that the application of untreated crop straw has little effect on the yield of wheat. Wheat yield was 3.0 and 6.0 kg / hm2, respectively, and the seasonal wheat yield was 92.8% and 96.0% of the control respectively, with a yield reduction of 7.16% and 4.0%, respectively, with no significant reduction in yield. When corn stover was used instead of wheat straw, the wheat yield was 99.1% and 103.2% of the control, with or without a slight increase from the control. Wheat straw yield was increased by 3.60% and 1.45%, respectively, compared with 99.5% and 103.2% of no straw applied (control). Corn straw decomposition faster than wheat straw, the effect is good, crushed can be directly returned to the field
