摘  要:用广谱性的活性能营养剂“活力素”在玫瑰香葡萄、西瓜及大白菜上进行了喷施试验,葡萄以1000倍液喷1~4次,大白菜喷2~3次,西瓜分别以800,1000,1200倍液喷2次。结果表明:喷施活力素对改善作物品质、增强抗病性有良好的作用,葡萄含糖量增加,可滴定酸含量降低,糖酸比增加且着色好,西瓜含糖量提高,pH提高,口感较好,大白菜增加了净菜率,降低了软腐病发病率,硝酸盐含量下降。建议葡萄和大白菜以1000倍液喷2次,西瓜800~1200倍液在团棵期及小瓜落地期各喷1次。“Huolisu”is a kind of broad spectrum and active mixed nutrient.The applied experiments were carried on grapes,water melons and Chinese cabbage.The 1 000fold dilute solution of“Huolisu”was sprayed 1 to 4 times on grapes and 2 to 3 times on Chinese cabbage at the growing period.The 800,1 000,and 1 200fold dilute solution,respectively,was sprayed 2 times on water melons at the growing period.The results showed that there were good effects of spraying“Huolisu”on improving crop qualities and increasing crop resistance to disease.“Huolisu”can increase the sugar content,decrease the titrable acid content,increase the sugar/acid ratio and color deeply on grapes.The water melons were obtained high sugar content,pH,and good taste after spraying“Huolisu”.The net percentage of Chinese cabbage was increased.The disease incidence of soft rot and nitrate content of Chinese cabbage were decreased after spraying“Huolisu”.It suggested that 1 000fold dilute solution of“Huolisu”is sprayed two times on grape and Chinese cabbage at the growing period.The dilute solution of 800 to 1 200,flod respectively,can be used to spray two times on water melon at growing period.
