Snowflake Pear Flower Powder For Pollination Of Pear Trees
1 Because pollen is active and living, it cannot be stored at room temperature for a long time. If it is used in 3 days, you can put it in cold storage. If it is due to inconsistent flowering time, Some flowers bloom early on the sunny side of the mountain, while others bloom late on the shady side of the mountain. If the use time is more than a week, you need to put the pollen in the freezer to reach - 18 ℃. Then take the pollen out of the freezer 12 hours before use, put it at room temperature to change the pollen from dormant state to active state, and then it can be used normally. In this way, the pollen can germinate in the shortest time when it reaches the stigma, so as to form the perfect fruit we want.
2. This pollen cannot be used in bad weather. The suitable pollination temperature is 15 ℃ - 25 ℃. If the temperature is too low, the pollen germination will be slow, and the pollen tube needs more time to grow and extend into the ovary. If the temperature is higher than 25 ℃, it can not be used, because too high temperature will kill the activity of pollen, and too high temperature will evaporate the nutrient solution on the stigma of flowers waiting for pollination. In this way, even pollination will not achieve the harvest effect we want, because the nectar on the flower stigma is a necessary condition for pollen germination. The above two conditions require careful and patient observation by farmers or technicians.
3. If it rains within 5 hours after pollination, it needs to be re pollinated.
Keep the pollen in a dry bag before shipment. If pollen is found to be moist, please do not use moist pollen. Such pollen has lost its original activity.
