摘要
为解决油茶的大小年现象,确定合理的留枝类型,对油茶不同类型新梢中营养分布进行了研究。选取油茶6种不同类型新梢,并测定了与对不同类型新梢并生的果,新梢上的枝、叶、花芽的干物质量,可溶性糖、淀粉质量分数等生理指标,以研究油茶6种类型新梢的营养分布状况。结果表明:Ⅰ类长枝的营养优先供给自身,Ⅱ类长枝和短枝会为来年储备更多的营养物质,所以在疏果时可以疏与Ⅰ类长枝并生的果,尽可能保留Ⅱ类长枝和Ⅱ类中枝作为下一年的挂果枝。
To keep the rational new shoot for the problem that the yield of Camellia oleifera is high in one year but low in the next year, we studied the differences among six kinds of new shoot of Camellia oleifera , including photosynthetic rate of young leaves grow on shoot, and dry matter, soluble sugar content, starch content of young leaves, bud, and fruit belonging to the six kinds of shoot. The results show that the Class Ⅰ long branch gives priority to supply nutrition to themselves and Class Ⅱ long branches and Class Ⅱ medium branches will reserve more nutrients for the coming year. It can be concluded that more fruits near Class Ⅰ long branches and Class Ⅰ short branches achieve the optimum amount of reserved fruit, as far as possible to retain the Class Ⅱ long branches and Class Ⅱ medium branches as the next year’s fruiting branch.
