摘要
应用植物替代、人工拔除和机械旋耕等农业措施控制加拿大一枝黄花研究结果表明,种植替代植物水稻、小麦、玉米和大豆等作物对加拿大一枝黄花均有一定的防效,鲜重防效明显高于株数防效,对株高的防效最小。其中种植水稻的防效达100%。人工拔除加拿大一枝黄花的地上部分和地下部分后种植青菜和芝麻,其株数防效和鲜重防效均可达95%以上。机械旋耕对加拿大一枝黄花株高的控制效果在50%左右,鲜重的防效可达70%,但旋耕后其密度会大量增加。
The effects of agricultural measures such as plant displacement,hand-removing or rotary tillage on control of Solidago canadensis L.Were investigated.Planting displacement with rice,wheat,or corn could control S.canadensis L.,with control efficiency on fresh weight significantly higher than that on plant number.The control efficiency of rice displacement on S.canadensis L.was 100%.Pakchoi and sesame planting after eradication of ground and above-ground goldenrod by hand gave above 95% control efficiency on fresh weight and plant number.The control efficiency of plant height and fresh weight by rotary tillage were about 50% and 70%,respectively however,the density of S.canadensis was significantly increased by rotary tillage.
