度尾蜜柚自然结实率低,用异品种人工授粉后,不同程度地提高座果率,增加单果重,降低裂果率,果实外观好看,商品率提高。为了探讨不同授粉组合对度尾蜜柚产量及果实品质的影响,筛选出优良的授粉组合,开设“度尾蜜柚优良授粉组合选择的试验”。试验设在红星村十一年生柚树及中峰六年生树上,在4月中旬柚子花盛开时,选择花器发育正常花进行授粉,授粉组合有:土酸柚、沙田柚,琯溪蜜柚,远距离的度尾蜜柚,及白花授粉,四个组合,一个对照。套袋隔离。经两年试验,已取得初步结果。
Degree tail tail pomelo natural seed setting rate, artificial pollination with different varieties, to varying degrees, increase the rate of fruit set, increase the weight of fruit, reduce the rate of fruit cracking, the appearance of good-looking fruit, commodity rate increase. In order to explore the effects of different pollination combinations on the yield and fruit quality of pomelo, the excellent pollination combinations were screened out and the experiment of selecting the best pollination combinations of pomelo was done. The trial was set in the eleventh-year grapefruit tree and Zhongfeng six-year-old tree in Hongxing village. When the grapefruit flower was in full bloom in mid-April, the normal flower of the flower organ was selected for pollination. The pollination combination was: Tu acid grapefruit, Long tail of pomelo, and white flowers pollination, four combinations, a control. Bagging isolated. After two years of testing, preliminary results have been achieved.
