迁西县有安梨结果树17万株,由于开花较早,与鸭梨、雪花梨花期不遇,而且多数果园品种单一,往往是开花多,座果少,产量低而且质量差。为解决这个问题,1990—1992年,我们在本县三屯营镇六宝峪村的山脚平地梨园(树龄40年)和汉儿庄乡路庄村山坡梨园(10年生),进行了3年的田间试验研究,筛选出人工辅助授粉是提高安梨产量与质量的有效技术措施。人工授粉花朵座果率较自然授粉的提高2.52倍,产量提
There are 170,000 trees of Ann pear in Qianxi County. Because flowering is earlier, flowering pear plants and snowflakes will not meet the flowering season. Most of the orchards are single, often with more flowering, fewer fruit sets, lower yield and poor quality. In order to solve this problem, in 1990-1992, we spent three years in Liupanyingliyuan (40 years old) and Luoliyuan (10 years old) in Luzhuang Village, Hanzhuang Township, Field trials and research, screening of artificial pollination is to improve the yield and quality of An Pei effective technical measures. Artificial pollination of fruit rate of 2.52 times higher than the natural pollination, yield mention
