吉林省蓖麻除草剂田间筛选

Field Selection of Castor Herbicides in Jilin Province

为有效防控蓖麻田间杂草,在以往试验的基础上通过选用多种土壤处理除草剂,采用不同配比、不同剂量分别在蓖麻播后苗前和开花前对蓖麻田杂草进行除草剂处理。结果表明:经田间观察、杂草发生情况以及蓖麻收获产量计算,筛选出二甲戊灵+五氟磺草胺3倍剂量播后苗前土壤处理是蓖麻田最理想的除草剂组合、用药剂量和杂草防控方法。

In order to control the field weeds in the castor plots effectively,the castor field was treated with more different soil treatment herbicides,by the different proportions and volumes on the base of former trial at after sowing and before seedling,and before flowering.The results showed that the soil treatments with pendimethalin,penoxsulam in three time doses were the best herbicide group、dose and methodby calculating the weed occurrence and castor yields.
