一、在果菜类的幼苗期抑制徒长,培育壮苗。为了抑制蔬菜幼苗徒长,可以喷施矮壮素,抑制其细胞伸长,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,用量每平方米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,叶色青绿,叶片增厚,植株变矮,可以维持20—30天。二、在果菜类生长期防落 First, the fruits and vegetables in the seedling inhibition of leggy, nurturing strong seedlings. In order to restrain the growth of vegetable seedlings, chlormequat can be sprayed to inhibit the cell elongation, making the plant 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 100-200 ml, to prevent leggy, 5-6 days after use in the slow growth of stems, green leaves, thickened leaves, plant shorter, you can maintain 20- 30 days. Second, the growth of fruits and vegetables in the fall
