在黄瓜、茄子、菜豆等蔬菜上巧妙使用植物生长调节剂赤霉素,能取得良好的增产效果。黄瓜(1)棚室黄瓜因温度不足或结瓜太多等原因出现「花打顶」现象时,用20毫克/公斤赤霉素溶液喷洒,能促使植株恢复生长。(2)棚室黄瓜发生灰霉病,尚未侵染瓜部时,摘除花冠,用赤霉素(50毫克/公斤)与速克灵(500毫克/公斤)的混合溶液涂抹伤口,可以防 In cucumber, eggplant, beans and other vegetables clever use of plant growth regulator gibberellin, can achieve good yield. Cucumbers (1) Cucumbers Cucumbers When sprayed with 20 mg / kg gibberellic acid (GA3) solution due to insufficient temperature or too much water, the plants can be restored to growth. (2) Cucumber in greenhouse had Botrytis cinerea which had not been invaded by melon, the corolla was excised, the wound was coated with mixed solution of gibberellic acid (50 mg / kg) and sck (500 mg / kg)
