人工辅助授粉是众多果品生产实现高产稳产的重要措施。以梨为例,90%以上的品种须异品种授粉才能结实,凡梨园授粉品种不足,或因花期阴雨低温、干热风等不良天气,着果率将明显降低。笔者根据果农长期积累的经验,系统总结了人工授粉省工高效的实用技术,要点如下:1.抢先采花制粉,雨 Artificial assisted pollination is an important measure for many fruit production to achieve high and stable yield. To pear, for example, more than 90% of the varieties must be different varieties of pollination to fructification, where the lack of varieties of pear or pollen, or flowering due to cold weather, dry hot air and other adverse weather, fruit rate will be significantly reduced. The author based on long-term accumulated experience of fruit farmers, the system summarizes the artificial pollination and efficient and practical technology, the main points are as follows: 1. Picking the first flower milling, rain
