Abstract:

In 2012，taking ‘Jinlong-2’ and ‘Hayward’ as materials，10-mesh nylon net bagged pollination test was conducted in the four directions of east,west,south and north.The pollination effect of kiwi male pollen at different distances under natural conditions was studied.The results showed that pollination distance of 1 m in four directions，two varieties of fruit setting rate had an average of less than 50% of pollination.Pollination distance of 3 m，had an average of less than 10% fruit setting rate，pollination distance of 5 m，the fruiting rate was less than 4%.There were differences between the two varieties.When the pollination distance was greater than or equal to 3 meters，the removal of ‘Hayward’ north to the fruit setting rate was 27% and the south 12.5%,‘Jinlong-2’ the south and the west to 7.4% and 3.7%，and the fruit setting of others was 0；‘Hayward’ 0 distance of fruit setting was 100%，0.5 m of fruit setting rate was 71%～89%，distance of fruit setting rate was 41%～88%.The‘Jinlong-2’ setting rate was 7.7%～30.6% 0.5 m away,3.6%～21.6% 1 m away.In 2011，with ‘Xuxiang’,‘Hayward’，and ‘Miliang’ as test materials，distance from male plants was greater than 3 m with bagging，three varieties of muti-fruit setting rate were 0，but within the bagging the artificial pollination and fruit setting rate was nearly 100%.Two-year results were consistent.Results indicated that natural wind pollination was weak,wind-pollinated had little influence on kiwifruit pollination.
