苹果树自花结实率一般很低。当授粉树配置不足或花期天气不好,缺少昆虫传粉时就会影响授粉,造成减产。在这种情况下,采用人工授粉是提高产量的有效措施。近几年来,不少苹果产区社队已进行了大面积的人工授粉,增产效果显著。1972年成都地区在苹果花期中有四天降温降雨天气,四川省农科院实验农场果园工人抓紧时机,高举“农业学大寨”的旗帜,反复进行了两、三次人工授粉,结合修剪、发芽前灌溉、施肥、防治病虫等措施,
Apple trees self-fertility rate is generally low. When the pollination tree configuration or flowering weather is not good, lack of insect pollination will affect pollination, resulting in reduced production. In this case, using artificial pollination is an effective measure to increase production. In recent years, many apple producing communities have conducted a large-scale artificial pollination, yield significant results. In 1972, there were four days of rainy days in the flowering season of apple blossoms in the apple blossoms. Workers in the orchard of the experimental farm in Sichuan Academy of Agricultural Sciences seized the opportune moment to hold high the banner of “Agriculture Studies in Dazhai” and repeated two or three artificial pollination with pruning and sprouting Before irrigation, fertilization, pest control and other measures,
