闽南垦区橡胶秋季育苗达到茎粗2公分的芽接标准,通常需要一年半时间,苗木生长赶不上次年秋季芽接。因为生产上多是采用秋季芽接,苗木带干越冬,春季移苗定植。为了使胶苗在一周年内达到芽接标准,以缩短非生产期,减少管理费用,必须采取有效措施,促进苗木快速生长。我所曾从海南引进一批橡胶种子,当年秋播育苗20亩,进行丰产试验,一周年平均茎粗达2.055公分,与普通苗相比茎粗增大15～20％。其中5亩丰产片一周年平均茎粗达2.224公分,比普通苗茎粗增加20～25％。现将我们快速培育胶苗的试验情况小结如下。
Minnan reclamation rubber seedlings in autumn to reach 2 cm stem diameter standard budding, usually takes a year and a half, seedling growth catch up with the autumn budding the following year. Because the production is mostly used in autumn budding, seedlings with dry winter, spring seedling colonization. In order to make the seedling budding meet the standard in the first year to shorten the non-productive period and reduce the management cost, effective measures must be taken to promote the rapid growth of seedlings. I have introduced a batch of rubber seeds from Hainan, when the autumn sowing 20 mu of seedlings for high yield test, the average annual stem diameter of 2.055 cm, compared with ordinary seedlings increased 15 ~ 20%. Among them, the average stem diameter on the first anniversary of 5 mu of high-yielding slices is 2.224 cm, which is 20-25% more than that of ordinary shoots. Now we quickly cultivate gel test summary is as follows.
