嗪草酮对1年生阔叶杂草和部分禾本科杂草具有防效,烯草酮对田间禾本科杂草具有防效,本试验对嗪草酮和烯草酮混用防除加工番茄田间1年生杂草的除草效果、最佳施药量及对加工番茄的安全性进行了研究。试验结果表明,嗪草酮30 g/667 m2、烯草酮50 g/667 m2对供试加工番茄安全,是施药安全剂量,同时也是田间杂草防效最佳比例,施药后30 d对1年生阔叶杂草植株防效达93.33%,鲜重防效达94.33%;对禾本科杂草植株防效达95.67%,鲜重防效达95.33%。
Melachlor on the 1 year-old broadleaf weeds and some grass weeds have control effect, clethodim on the field weeds grass has control effect, the test of metribuzuron and clethopamycin mixed with control of 1-year-old tomato field Weeding weeding effect, the best application rate and the processing of tomato safety were studied. The results showed that 30g / 667m2 of melatonin and 50g / 667m2 of clethrene were safe for the processing of tomato, and the safe dose of melatonin was the best proportion of weeds in the field. After 30 d The control effect on the annual broadleaf weeds was 93.33% and the fresh weight control efficiency was 94.33%. The control effect on weeds was 95.67% and the fresh weight control efficiency was 95.33%.
