| 摘 要： | 通过对棉花不同生长发育期喷施沼液、磷酸二氢钾和清水的研究，结果表明，早期喷施沼液和磷酸二氢钾均能不同程度的抑制田间虫口数量增长和蚜虫扩散，对蚜虫的虫口数量减弱作用可持续10d左右。蚜虫迁入高峰期，喷施磷酸二氢钾对蚜虫迁入具有明显抑制作用，沼液的抑制作用相对较弱；蚜虫大发生期间不宜喷施沼液，沼液对叶片营养的改善有促进蚜虫虫171数量增加，延缓虫口数量减退的作用。

| Abstract: | Spraying cotton plant with biogas slurry,potassium dihydrogen phosphate and water in the dif- ferent cotton growing time. Early results showed that spraying biogas slurry and potassium dihydrogen phosphate can not inhibit the growth and the proliferation of the field population in different levels. The population of aphids could be decreased for about 10d. Spraying potassium dihydrogen phosphate has obvous inhibition effect on the aphids moving into the fields. Spraying biogas slurry could not significantly control the occurrence of aphids. As it could help aphids to be increased and delay its population decrea-sing. |
