果农朋友，面对今年猕猴桃花期出现的灾害性天气，特在猕猴桃授粉环节提醒大家：
①温度低于15度不要授粉。
（建议17度之上开始授粉，温度17度是蜜蜂开始访花采粉的温度，随着温度的逐渐升高，花粉的发芽率增加和花粉管的生长也会不断加快。所以蜜蜂都开始访花采粉了，我们也要抓紧时间及时授粉。
②阴雨天不建议授粉，因连阴雨没办法，确要授粉的，需要雨停后3小时以上，将树上雨水摇摆后，待雌花柱头雨水滴干，可以及时授粉。

③近期阴雨连绵，温度偏低，建议加大花粉用量（减少辅料的比例，最好1：1的配合），可以比正常年份增加1倍以上的花粉用量，每10克纯花粉中加上碧护2克混匀使用。碧护的作用就是：一是能保护雌花柱头提高抗低温和高温能力的作用；二是能促进雌花柱头产生分泌黏液物质，粘上花粉；三是有提高花粉发芽率及促进花粉管生长速度加快的作用。达到授粉受精成功。

④根据天气变化情况，灵活选择机会多次授粉，做好授粉后的果园查看工作，授粉后第二天若柱头直立，需要重新补授。没有授上粉的雌花柱头可以有4天至5天的补授时间（如果柱头没有干缩萎蔫，脆白色），就可以补充授粉。
面对今年授粉期间的极端天气，我们只有关注天气及温度变化，择机授粉，柱头花粉沾足，柱头着粉要匀。建议多次授粉，并及时查看，做好补授，尽人力最大化减少天气对授粉的影响。

Dear fruit farmers, in the face of the catastrophic weather that occurred during the kiwi flowering period this year, we would like to remind everyone during the kiwi pollination process:
① Do not pollinate at temperatures below 15 degrees Celsius.
It is recommended to start pollination above 17 degrees Celsius, which is the temperature at which bees begin to visit flowers and collect pollen. As the temperature gradually increases, the germination rate of pollen increases and the growth of pollen tubes also accelerates. Therefore, bees have started to visit flowers and collect pollen, and we should also seize the time to timely pollinate.

② It is not recommended to pollinate on rainy days because it is impossible to do so. If pollination is necessary, it is necessary to wait for at least 3 hours after the rain stops, shake the rainwater on the tree, and wait for the water droplets on the female flower head to dry before pollination can be carried out in a timely manner.
③ Recently, there has been continuous rainy weather and low temperatures. It is recommended to increase the amount of pollen used (reduce the proportion of auxiliary materials, preferably in a 1:1 combination), which can increase the amount of pollen used by more than twice compared to normal years. Add 2 grams of Bihu to every 10 grams of pure pollen and mix well before use. The function of Bihu is to protect the stigma of female flowers and enhance their resistance to low and high temperatures; Secondly, it can promote the secretion of mucus substances from the stigma of female flowers, which can adhere to pollen; Thirdly, it has the effect of improving pollen germination rate and accelerating the growth rate of pollen tubes. Achieve successful pollination and fertilization.

④ According to weather changes, flexibly choose opportunities for multiple pollination, and do a good job of inspecting the orchard after pollination. If the stigma is upright the next day after pollination, it needs to be re pollinated. Female flowers that have not been pollinated can have a supplementary pollination period of 4 to 5 days (if the stigma is not withered or brittle white).
Faced with the extreme weather during this year's pollination period, we can only pay attention to weather and temperature changes, choose the right time for pollination, and ensure that the stigma pollen is evenly spread. It is recommended to pollinate multiple times, check in a timely manner, make up for the missed pollination, and minimize the impact of weather on pollination as much as possible.
