前言 自从1967年马来西亚首先使用乙烯利刺激胶树获得大幅度的增产效果以来,在这近十年间,世界上各植胶国对乙烯利刺激增产的研究作了大量的工作,并取得了很大的成绩。我国的广东、云南、广西、福建等垦区从1971年起也进行了试验研究,积累了不少资料。但由于我们垦区的割胶历史较短,生产上大面积投产的芽接树如PB86、PR107、GT1RRIM600等品系大都是1963年前后定植的,树龄较小,并受病、寒害;有老实生树较多的单位,也由于各种原因,还未广泛使用乙烯利。当前,我们云南垦区,在第二次全国农业学大寨会议精神鼓舞下,斗志昂扬,决心种好胶,多产胶,为国家多作贡献。积极
INTRODUCTION Since Malaysia first used ethephon to stimulate gum trees in 1967 to achieve a dramatic increase in yield, a great deal of work has been done on the research on increasing ethephon production in the past ten years in this country, and a great deal has been achieved The score. China’s Guangdong, Yunnan, Guangxi, Fujian and other reclamation area since 1971 also conducted a pilot study, has accumulated a lot of information. However, due to the short history of tapping in our reclamation area, budding trees such as PB86, PR107 and GT1RRIM600 put into operation in large-scale production mostly were planted around 1963, with smaller ages and suffering from diseases and chills; Of the units, but also for a variety of reasons, not yet widely used ethephon. At present, our Yunnan reclamation area, inspired by the spirit of the Second National Conference on Agriculture in Dazhai, is full of vigor and determination and is determined to make good use of plastic and plastic products to make more contributions to the country. positive
