“育秧”是甘蔗生产中的重大技术改革,将成为今后甘蔗生产中一个重要环节。当前,世界上绝大部份蔗区都是采用甘蔗梢头苗种植的,因为,甘蔗不是每个地方都能开花结籽,而且种子细小,杂交后代分化大,培育条件要求较高,当年产量不好。因此,在生产上一直都是习惯采用种苗种植的,用种量大,产品率低,成本重;种苗切口多,抗病力比种子弱,
“Raising seedlings” is a major technological reform in the production of sugar cane and will become an important link in the future production of sugar cane. At present, most sugarcane growing areas in the world are planted with sugarcane shoots, because sugarcane can not bear flowering and seed in every place, and the seeds are small and the offspring of hybrids are highly differentiated and require higher cultivation conditions. it is good. Therefore, the production has always been accustomed to the use of seedlings planted, with a large amount of products, low rate, cost heavy; seedling cutting more resistance than the weak seed,
