| 摘 要： | 用除草剂骠马的3种喷施剂量对核桃树幼苗进行处理,研究其对核桃幼苗生长发育及一些生理指标的影响。结果表明:骠马1/2推荐喷施剂量(2 .5ml/L)对核桃幼苗的叶绿素、丙二醛、可溶性糖含量及株高生长量的影响最小;2 .5ml/L和5ml/L处理仅在喷药后5d作用显著,10ml/L处理在喷药后10～15d对核桃苗生长仍具有抑制作用。建议在核桃苗圃使用骠马除草时,应于核桃萌芽前后5d施用,浓度不高于5ml/L。

| Abstract: | The result the test with 3 spraying concentration of herbicide fenoxaprop p ethyl shows that the herbicide 2.5 ml/L spraying dosage has no marked influence on the amount of chlorophyll, MDA, solvable sugar at and plant height of walnut sapling. 10ml/L herbicide does not restrain the growth of walnut sapling until 10-15 days after spraying it. 5ml/L and 2.5ml/L herbicide produce distinct effect for 5 days after the application. Therefore in the walnut nursery the herbicide should be applied 5 days before or after germination and its density can't exceed 5 ml/L. |
