摘  要:
针对目前生产需要果树苗田化学除草,选用生产上常用的8种土壤处理除草剂进行温室盆栽安全性试验。结果表明,不同药剂对苹果砧木西府海棠(Malusmicromalus)幼苗的安全性不同,其中60%丁草胺150ml/667m2、72%异丙甲草胺200 ̄250ml/667m2、41%甲草胺200ml/667m2在海棠播后苗前施药安全。33%二甲戊乐灵150ml/667m2和48%氟乐灵100 ̄150ml/667m2在海棠5叶期施药比较安全。

摘  要:
Given the current need for producing chemical herbicides for seedling fruit trees, pot experiments were conducted in the greenhouse to determine Kaido crabapple (Malus micromalus) seedling susceptibility to 8 commer- cial soil-applied herbicides. Apple seedling susceptibility varied among the 8 herbicides. Butachlor, metolachlor, and alachlor were not injurious to crabapple seedlings applied preemergence at 2250, 3000-3750, and 3000 ml/ha, respectively. Pendimethalin and trifluralin at 2250 and 1500-2250 ml/ha, respectively, provided relatively good safety when applied at the 5-leaf stage.
