1、严格掌握使用浓度。番茄灵的使用浓度一般为30～50ppm,“2,4—D”多为15～20ppm。高温时,浓度要适当降低。“2,4—D”多用毛笔涂或浸蘸,最好不喷用,以防药害。蘸花时药液也不要过多。万一出现药害,应立即浇大水。 2、不用金属容器配药。特别是生锈的铁锅铁盆等,以免发生化学反应而降低药效,配药的容器最好是搪瓷盆或玻璃器皿。药液配好后,应装入带
1, strictly control the use of concentration. The concentration of tomato spirit is generally 30 ~ 50ppm, “2,4-D” mostly 15 ~ 20ppm. High temperature, the concentration should be appropriately reduced. “2,4-D” brush or dip more with brush, it is best not to spray to prevent injury. Dip the flowers when the liquid is not too much. In case of injury, immediately pour floodwaters. 2, no metal container dispensing.
