荔枝多梢是影响翌年成花结果的因素之一。“出冬梢、春无花”,幼龄树早花与花量大,是造成花而不实的弊病根源。用人工控梢如:环枝、挖根、摘梢较花工、费本,技术性高。据国内外报导:应用青鲜素(MH)、比久(B_(?))在柑桔及苹果上进行控梢、促花有一定成效。1978年我们曾试用青鲜素、比久抑制荔技冬梢生长取得不同效应。1979年继续试验,进一步明确植物生长调节剂对荔枝控梢促果的效应,探索简便有效方法,获得荔枝早产丰产。现将试验结果初步整理出来,供参考。
Litchi shoots are one of the factors that affect the flowering result of the following year. “The winter shoot, spring without flowers”, young trees early flowering and flowers, is the root cause of the defects of flowers and not real. With manual control tip such as: Central branch, dig the root, picking more than flower workers, cost, high technical. According to reports at home and abroad: the application of fresh greens (MH), longer than (B_ (?)) In the citrus and apple on the control tips, promote flowers have some success. In 1978 we have tried green, longer than the inhibition of Lai Tip Winter growth achieved different effects. In 1979 to continue the experiment to further clarify the effects of plant growth regulators on litchi Shoots promote fruit, to explore simple and effective method to obtain litchi preterm high yield. Preliminary test results are now sorted out for reference.
