- 摘要:
- 以河北省农林科学研究院昌黎分所梨园为例，2013年周年调查了纺锤形和Y字形黄冠梨的梨木虱发生动态，研究该2种树形与梨木虱发生时间及其数量的关系。结果表明：在相同管理模式下，2种树形的梨木虱发生时间动态无显著差别，但纺锤形树体的梨木虱数量明显低于Y字形树体的数量，表明纺锤形树形可以减轻梨木虱的危害。
- Abstract:
- The dynamics of Cacopsylla chinensis on the spindle-shaped and Y-shaped‘Huangguan’pear trees were monitored in Changli in 2013，the relationship between the structure of pear trees and the occurrence of C.chinensis was studied.The results showed that there was the same dynamic between the two structures in consistence management，the numbers of C.chinens on the spindle-shaped trees were significantly lower than that in the Y-shaped trees.In conclusion，the spindle shape of the tree was unfavorable for C.chinensis.
