平欧杂交榛子一年生枝修剪反应

Pruning Response of Annual Branches on Corylus heterophylla×corylus avellana

对‘达维’一年生枝进行不同程度短截,随着短截程度的加重,萌芽量逐渐减少,萌芽率以剪留60%的最高;最大枝长以剪留80%的最长;平均新梢长以剪留最短的最长;本枝总生长量以缓放的最高,本枝基部粗度增长率以缓放的最高;本枝坐果量以剪留80%的较多。

By varying degrees of shear cutting test（respectively cut 5cm,30%,60% and 80% to slow for con- trol）of ＇Davey＇annual branches,The results showed that with the increase of shear rate,the germination rate was gradually reduced, the germination rate was the highest, and the growth rate of the single branch was the highest ,and the single branch growth rate was the highest in 80% ;The average growth rate of the average growth rate of the new shoots was longer;The total number of the base crude and the total branch growth of the delayed release was increased by the maximum;80% was the best cut.The total number of the base crude and the total branch growth of the delayed release was increased by the maximum.
