国家天然橡胶产业技术体系研发先进育苗技术

今天就由中国国际橡胶技术展小编将为你解读更多行业新趋势。

近年来，国家天然橡胶产业技术体系开发了小型苗、大型苗、自根苗等多种类型苗木，其中以籽苗芽接发展起来的小型苗在云南、广东各生产性苗圃得到广泛应用，10年来，累计生产近1500万株，成为橡胶树种苗扩繁的主导技术，并成为“一带一路”橡胶树育苗技术走出去的主力，分别在马来西亚建设了年生产能力达200万株、在柬埔寨年达100万株的育苗基地。

据记者了解，开展大型全苗的培育和配套定植技术，可缩短非生产期1-2年。在世界上首个突破主栽品种的体胚发生和多代次大规模扩繁技术，以橡胶树花药、内珠被等外植体体胚发生为基础，诱导体细胞胚次生体胚发生，实现胚到胚的循环增殖，最终达到橡胶树自根幼态无性系快速增殖的目的。此外，体系还建立了一套较为成熟的工厂化生产技术与工艺，年体胚增殖系数达10000，体胚再生植株频率平均达70%，体胚植株沙床移栽成活率达90%以上，装袋成活96%。

根据之前研究人员大量的研究和本研究团队的大田生产性验证，结果表明自根幼态无性系对比常规芽接苗速生，缩短1年非生产期、林相整齐、茎围均一度高、主干干性强、抗风优良，同比增产20%-30%。

以上便是中国国际橡胶技术展小编从农民日报为大家整理的相关内容，如果大家对这方面比较感兴趣，可以到中国国际橡胶技术展参观交流。2021年10月20-22日，中国国际橡胶技术展将联合第二十届中国国际化工展、第二十四届中国国际胶粘剂及密封剂展、2021中国石化产业安全环保展同期、同地举办，共同打造“中国石化产业周”，实现全产业链及全球视角宣传，届时将有超过5万人次的国内外专业观众莅临现场将在国家会展中心（上海）隆重开幕，将为你解读更多行业发展新趋势。
