齐齐哈尔市化工研究所研制出一种ESD增糖剂。经6年大区试验证明,该增糖剂对水果、西瓜、甜菜、葡萄、西红柿具有良好的增糖效果,是一种无毒、无药害、对人畜安全的药剂。ESD增糖剂用于果树使用量为100—250克,浓度是800—1,000ppm,收获前3—4周对叶面全部喷湿一次。用于西瓜,葡萄、西红柿、桃、梨、柿等喷施,浓度是1,000ppm,收获前30天 Qiqihar Institute of Chemical Industry has developed a kind of anti-hyperglycemic agents. After six years of large area tests proved that the sugar enhancer on fruit, watermelon, sugar beet, grapes, tomatoes have a good effect of increasing sugar, is a non-toxic, no pesticides, human and animal safety agents. ESD sugar enhancer for fruit trees in the amount of 100-250 grams, the concentration of 800-1,000 ppm, 3-4 weeks before harvest on the leaves wet all wet once. For watermelon, grapes, tomatoes, peaches, pears, persimmon and other spray, the concentration is 1,000ppm, 30 days before harvest
