| 摘 要： | 以益农103为试验材料,选择条深旋耕、普通旋耕和免耕3种耕作方式,比较分析了不同耕作方式对早春季玉米产量性能的影响。结果表明:条深旋耕条件下玉米的产量比普通旋耕和免耕分别增产11.1%和17.6%,干物质产量分别增加8.5%和12.9%。条深旋耕条件下开花后叶面积指数(LAI)较长的高值持续期有利于干物质积累量的增加。群体光合势(LAD)、平均作物生长率(MCGR)、平均叶面积指数(MLAI)、平均净同化率(MNAR)、开花期穗位叶绿素含量(SPAD)和净光合速率(Pn)的增加提高了作物的光合速率和光合产物向子粒转运的速率,同时也提高了穗粒数和千粒重。说明条深旋耕作措施有利于改善早春玉米群体产量性能,从而获得较高的产量。 |

| Abstract: | The yield performance of early spring maize in three cultivation ways,including strip deep tillage,traditional tillage and no-tillage,was studied using Yinong103 as material.The results showed that the yield in strip deep tillage increased by 11.1% and 17.6%,respectively,dry matter increased by 8.5% and 12.9%,respectively,comparing to that of the conventional tillage and no-tillage treatment.Leaf area index(LAI) after flowering under long duration benefited for increasing dry matter accumulation in strip de... |
