云南植胶从1953年开始,现已有一定的基础。到1980年为止,植胶总面积73.5万亩,投产开割30万亩,年产干胶已达到1.7万吨的规模。 云南垦区处于北纬21°08′～24°49′,植胶海拔高度,哀牢山以东350～400米,以西900～1,000米,是我国纬度最北,海拔最高的植胶区。 在二十多年的植胶过程中,不断认识垦区的自然规律,总结正反两方面的经验教训,植胶科技水平不断有所提高。已初步形成了一套较为完整的植胶措施和制度,包括基了一批经过多年选择鉴定的外来和自育的品系。这是我省今后植胶继续前进的技术有础。本文对最近几年来取得的在橡胶生产上有较大使用价值的几项科技成果作出评价并提出加快应用的意见,以期发挥优势,推动我省橡胶生产的发展。
Yunnan plastic planting since 1953, now has a certain foundation. Until 1980, a total area of 735,000 acres of plastic planting, production and opening cut 300000 acres, with an annual output of dry glue has reached the scale of 17000 tons. Yunnan reclamation area is latitude 21 ° 08 ’~ 24 ° 49’ latitude, planting glue altitude, 350 to 400 meters east of Ailao Mountains, west 900 to 1,000 meters, is the latitude of the most northern latitude, the highest elevation of the plastic area. In more than 20 years of plasticizing process, we continuously recognize the natural law of reclamation area, summarize the positive and negative experiences and lessons, and improve the level of plasticizing technology. A complete set of plasticizing measures and systems have been initially formed, including a series of foreign and self-adapted lines that have been identified for many years. This is the future of our province plastic glue to continue to advance the technology. This article evaluates several scientific and technological achievements made in recent years and has greater use value in rubber production and puts forward suggestions on accelerating its application in order to give play to its advantages and promote the development of rubber production in our province.
