为了明确美味猕猴桃同日内最佳授粉时间,以“海沃德”“徐香”“哑特”为试材,采用人工授粉方法,研究了不同时间授粉对猕猴桃果实性状的影响。结果表明:美味猕猴桃在晴天07:00—11:00和15:00—17:00平均单果质量分别为104.6g和102.1g;13:00和19:00单果质量较低,分别为89.1g和94.6g,平均91.9g,比上午和下午平均值103.4g低11.5g,减产11.1%;在06:00,9℃授粉的“徐香”“哑特”美味猕猴桃单果质量、坐果率比上下午2个时间段单果质量、坐果率平均值100g、78.0%,低28.3g、29.9个百分点,13:00湿度29%授粉的美味猕猴桃单果质量、坐果率比上下午2个时间段单果质量、坐果率平均值低8.9g、11.7个百分点;从不同品种看,“海沃德”和“徐香”单果质量日变化规律类似,上午优于下午,而“哑特”则相反。综上,在生产上美味猕猴桃以晴天上午授粉为主,温度低于9℃不能授粉,13:00和19:00不宜授粉。
In order to clarify the best pollination time of delicious kiwifruit in the same day, we used artificial pollination method to study the effects of pollination on the fruit traits of kiwifruit at different times using “Hayward” “Xu Xiang ” influences. The results showed that the average fruit weight of delicious kiwifruit in the sunny days was 104.6g and 102.1g at 07: 00-11: 00 and 15: 00-17: 00 respectively, and the fruit quality was lower at 13: 00 and 19: 00 94.6g, an average of 91.9g, lower than the morning and afternoon average of 103.4g 11.5g, a decrease of 11.1%; at 06:00, 9 ℃ pollination “Xu Xiang ” “dumb ” delicious Kiwi fruit quality, The fruit rate was higher than that in the morning and afternoon, the average fruit setting rate was 100g, 78.0%, 28.3g, 29.9%, 13% and 29%, respectively. The average fruit quality and fruit setting rate were 8.9g and 11.7% respectively. The diurnal variation of single fruit quality was similar between Hayward and Xuxiang, but the afternoon was better than the afternoon, Special "the opposite. In summary, the production of delicious kiwifruit pollination sunny morning, temperature below 9 ℃ can not be pollination, 13:00 and 19:00 should not be pollination.
