长把梨(山东梨)自花不育,在配置授粉树的条件下,自然座果率也很低。为了寻求长把梨授粉受精与提高座果率的途径,我们于1994年春在龙口市文基镇进行了本试验。现将部分试验结果总结如下。
Long pear (Shandong pear) self-sterile, with the conditions of the allocation of pollination trees, the natural fruit set rate is very low. In order to seek long way to pollinate pear fertilization and improve fruit set rate, we conducted the test in Wenji town, Longkou city in the spring of 1994. Now part of the test results are summarized below.
