摘要
为了提高梨树坐果率和果实品质,以"翠冠梨"为材料,采用人工授粉方法分别对梨花柱头可授性、授粉温度、授粉花朵序位以及授粉方式进行了研究。结果表明:在无低温和霜冻天气的上午8时至下午3时,采用授粉枪对梨树开花后3d内外围3个花序授粉,此时坐果率最高,果实综合品质最好,经济效益最大。
In order to improve the ＇Cuiguan＇ pear fruit-bearing rate and fruit quality, the pollination capability of stigma, pollination temperature, pollination flowers ordinal and pollination method were studied. The results showed that when peripheral three inflorescence were pollinated, using pollination gun, from 8 a.m. to 3 p. rn. within 3 flowering days without low temperature and frost weather, the pollination fruit-bearing rate, fruit comprehensive quality and economic benefit were the best.
