目前乙烯利(我国又名一试灵,见本刊1985年第二期封二)的应用研究,美国约有20种作物,全世界有30种作物用以促进成熟一致,增强色泽或作收获的辅助物。在小麦、大麦、玉米、棉花和甘蔗大面积应用获得丰收。在甘蔗方面,现已观察到5种不同的有益反应:①砍种和下种前三星期处理蔗种,能改善发芽不良,提高种苗萌发和生长齐一;②新植和宿根蔗植株长约30～50厘米时施用,可促进分蘖和生长,使茎干增大增重;③甘蔗收获前4～5个月施用,引起刺激茎顶部生长,增多节间数,蔗茎增长,增加生物量;④开榨前10～12周使用,导致早熟,能提高早期原料蔗汁的蔗糖含量;⑤一些高产抗病蔗种,常在收获前开花或抽穗,对糖产量很不利,应用乙烯利可抑制抽穗或阻止开花。
At present, the application of ethephon (China also known as a spirit, see the second edition 1985), the United States about 20 kinds of crops, the world’s 30 kinds of crops to promote the same maturity, enhance the color or harvest Of the auxiliary. In wheat, barley, corn, cotton and sugar cane large-scale application to obtain a good harvest. In terms of sugarcane, five different beneficial reactions have been observed: ① cutting and under the first three weeks of treatment of sugarcane can improve malnutrition and improve seed germination and growth of a homogeneous; About 30 to 50 cm when applied, can promote tillering and growth, increase stem weight gain; sugar cane 4 to 5 months before harvest, stimulated stem top growth, increased number of internodes, cane stem growth, increase biological The amount of sugar; ④ open crushing 10 to 12 weeks before use, leading to precocious, can increase the sucrose content of early raw sugar cane juice; ⑤ some high yield disease-resistant sugarcane, often flowering or heading before harvest, sugar production is very adverse, Can inhibit heading or prevent flowering.
