一、在果菜类的幼苗期抑制徒长、培育壮苗 蔬菜幼苗期喷施矮壮素,可以抑制细胞伸长,使植株变矮变粗。如对无限类型番茄品种,可以用200ppm矮壮素喷洒苗床土壤,用量每方米1000毫升。或在定植时每株浇250～500ppm矮壮素100～200毫升,防止徒长,在用后5～6天茎的生长变缓,叶色变绿,叶片增厚,植株变矮,可以维持20～30天。 First, the fruits and vegetables in the seedling inhibition of leggy growth nurturing seedlings spraying young plant chloride, can inhibit cell elongation, so that plants become shorter and thicker. For unlimited types of tomato varieties, you can use 200ppm chlorophyll spray seedbed soil, the amount of 1000 ml per square meter. Or planting 250 ~ 500ppm per plant when planting chloride 100 to 200 ml, to prevent leggy growth after use 5 to 6 days the stem slowed, green leaves, thickened leaves, plant shorter, you can maintain 20 ~ 30 days.
