| 摘 要： | 应用高压静电喷雾器喷施褐煤提取物（主要成分为腐植酸，还含有一些褐煤独有的小分子天然化合物）对大棚黄瓜瓜蚜进行防治。结果表明：在每667 m2用量 0.7~1.4 L范围内，每隔6~8 d喷1次褐煤提取物，可有效控制瓜蚜种群的发展，且每667 m2用量1.4 L，可使大棚黄瓜整个生长期内瓜蚜的种群数量维持在极低水平。

| Abstract: | Experiments were carried out for controlling Aphis gossypii Glover of cucumber with lignite extract in greenhouse.The results show that lignite extract with dosage of 10.5-21.0 L·hm-2 which sprayed with high power electrostatic spray system every 6-8 days can significantly reduce the quantity of Aphis gossypii Glover.Lignite extract with dosage of 21.0 L·hm-2 can make the quantity of Aphis gossypii Glover maintain extremely low lever in cucumber growth period. |
