甘蔗喷施赤霉素,增粗增高的效果显著,同时还可提高甜度。施用时要把握以下技术要点。适期喷施。甘蔗进入拔节初期,及时喷施第1次赤霉素溶液,以后每隔半个月再喷1次,整个生长期共呼3-4次。在大田观察发现,甘蔗喷施赤霉素后,不仅基部节间的长度增长,生长速度明显加快。并且成品蔗的质地酥脆,甜度较高。精确浓度。喷洒浓度可掌握在百万分之四十至百万分之五十,即每亩用85%赤霉素结
Sugarcane spray gibberellin, the effect of thickening increased significantly, but also can improve the sweetness. Application to grasp the following technical points. Spraying appropriate. Sugarcane into the early stage of jointing, spraying the first gibberellin solution, and then once every two weeks spray 1, call the entire growing season, a total of 3-4 times. Observed in the field found that sugar cane spray gibberellin, not only the length of the basal internode growth, significantly faster growth rate. And the texture of finished cane crisp, sweetness higher. Accurate concentration. Spray concentration can be controlled at forty-four millionths to fifty millionths, that is, with 85% GA per g
