| 中文摘要: |
| 通过对新和县1999、2002两年冬季铲除田埂杂草带棉田棉花卷叶率变化情况的观测,研究铲除田埂杂草对棉砾的防治效果。结果表明:苗期、蕾期防治效果可以达到70%～90%,棉花卷叶率下降3.35～16.83倍(P<0.05)。棉蚜越冬和早春迁飞与田埂上的杂草有关可能是这项技术有效的原因。 |
| 英文摘要: |
| The effect of weeding the bunds of cotton fields on cotton aphid (Aphis Gossypii) control was probed in Xinhe County of south Xinjiang and the percentage of leaf-rolled cotton is compared to that of control cotton. During the 2-year research, controlling efficacy on cotton aphid was 7090 percent in the seedling and buding periods, and percentage of leaf-rolled cotton decreases by 3.2516.83 times as much as before. There is significant difference between the treatment and the control, the effective farming technique is to regulate the relationship among cotton aphid overwintering, early spring immigrating and bund weeding. |
