1979年以来在果园对氟乐灵、阿特拉津、敌草隆、百草枯、扑草净等8种除草剂进行了三年试验、示范。证明48%氟乐灵乳剂对当年生禾本科杂草防除效果好,对果树安全。一、试材与方法在本所及祁县北团柏大队的桃园、梨园、果园试验,均以马唐、狗尾草、旱稗等杂草为主。马唐每平方米300株左右。旱地土壤处理:每亩用48%氟乐灵2两,机动喷雾器兑水300—400斤,背负式机动或手摇喷雾器兑水120—150斤,边喷边覆土,能杀灭杂草幼芽。若超过8小时不覆土,就会失效。有条件的可用机引圆盘耙耙两次。水地土壤处理:先把地锄平整,或灌药后再锄,避免土壤板结。再用少量水把药稀
Since the beginning of 1979, eight kinds of herbicides such as trifluralin, atrazine, diuron, paraquat and prometryn have been tested and demonstrated in the orchard. It is proved that 48% trifluralin has good control effect on current weeds and safety of fruit trees. First, the test materials and methods In the Institute and Qixian North Tung Bo group brigade in Taoyuan, pear orchard, are crabgrass, Setaria, barnyard grass and other weeds. Crab per square meter 300 or so. Dry land soil treatment: 48% of trifluralin 2 per acre, mobile sprayer watered 300-400 pounds, piggyback mobile or hand sprayer watered 120-150 pounds, side spray side cover soil, can kill weed sprouts . If more than 8 hours does not cover the soil, it will lapse. Conditional availability of disk rake rake twice. Soil water treatment: first to smooth the hoe, or irrigation and then hoe, to avoid soil compaction. Then dilute the drug with a small amount of water
