板栗是我省山区分布很广的核果类果树之一,但长期以来栗树产量低而不稳。造成低产的原因除管理粗放外,主要还是由实生繁殖造成的。实践证明,对低产大栗树利用良种接穗进行高接换头,一般当年便可结果,三年后株产量平均由2.5公斤增加到26.5公斤,增产十多倍。为能更快提高栗树产量,应对低产树进行高接换头。
Chestnut is one of the most widely distributed drupes in the province, but the output of chestnut has been low and unstable for a long time. In addition to extensive management of the reasons for the low yield, mainly caused by the real breeding. Practice has proved that the use of low-yield chestnut tree seedling scion exchange head, the general year can be the result, three years after the plant yield an average of 2.5 kg to 26.5 kg, an increase of more than 10 times. In order to improve the yield of chestnut trees more quickly, high yield heads should be dealt with in low yield trees.
