本文研究了无性系老茶树不同高度修剪的干物质产量及其分配情况,开始修剪高度为70、40、25和10厘米的茶树,发现在修剪后3年产生的干物质总量中只有一小部分分布在新生组织(叶、新枝和幼根)中,修剪初高为10厘米的茶树,叶子/骨架的干物质比率大于别的处理的,而地上部分/地下部分以及骨架/根系的干物质比率则小于其它处理的。据42个月的记录,修剪初高为10厘米的处理、即最小的植株,单位采摘面积的产量最高,但有效空间则以修剪初高为70厘米的大茶树最大。
In this paper, we studied the yield and distribution of dry matter of prunia old clones at different heights, and began to prune tea plants with heights of 70, 40, 25 and 10 cm and found that there was only a small amount of dry matter three years after pruning Partially distributed in the new tissue (leaves, new branches and young roots), the height of 10 cm tea plantations were trimmed, and the ratio of dry matter of leaves / skeletons was higher than that of other treatments. The aboveground / underground parts and dry matter The rate is less than the other treatments. According to the 42-month record, the pruning height of 10 cm is the smallest plant with the highest yield per picking area, but the effective space is the largest with a pruning height of 70 cm.
