酥梨属高强度自花不孕品种,由昆虫等传粉受精才能结果。因此,酥梨园除合理配置授粉树外,还必须进行人工辅助授粉,才能提高座果率,为实现酥梨丰产、稳产奠定基础。适宜的授粉时间和次数能有效地提高酥梨座果率,达到事半功倍的效果。 一、授粉时间对座果率的影响 酥梨从开花到谢花一般一周左右,由于此时天气变化无常,干风、冷风、阴雨天不断出现,有利授粉的时间很短,对此我们于1991-1995年连续五年对酥梨从开花当天到第6天分别进行授粉后调查座果情况(表1),结果表明:在开花
Pear is a high-intensity self-fertility varieties, insects and other pollination to fertilization results. Therefore, the pear orchard in addition to rational allocation of pollination trees, but also must be artificially assisted pollination, in order to improve the rate of fruit set, in order to achieve crisp pears yield, stable production and lay the foundation. Appropriate pollination times and times can effectively improve the rate of pear fruit, to achieve a multiplier effect. First, the impact of pollination time on the rate of fruit Pear Pear pear from the flowering to thank the flowers generally about a week, due to the weather was volatile at this time, dry wind, cold wind, rainy days continue to appear, favorable pollination time is very short, which we in 1991 - In 1995 for five consecutive years of pear from the day of flowering to the sixth day of pollination were investigated after the situation (Table 1), the results show that: flowering
