When is the best pollination time for kiwifruit?

The best time for pollination is from 8 am to 1 1 on sunny days.

When more than 70% of the female flowers in the whole garden are open, pollination is usually carried out 3-5 days after the male flowers are open. Be sure to grasp the time when pollinating. When the time is early, the humidity in the orchard is relatively high, and when the time is late, the temperature is relatively high, which will affect the pollen activity after pollination, thus affecting the pollination effect.

Selecting unopened male flower buds to be developed, cutting them, collecting them in a flower container, and drying; Do not collect completely open male flowers, because such flowers have less effective pollen.

Cut off the filaments with sharp scissors and sift out the pollen with a sieve. Pollen can be stored at room temperature for 18-36 hours and in a refrigerator at 6 degrees Celsius for about a week, but the longer the storage time, the lower the effectiveness of pollen.

The optimum pollination temperature of kiwifruit is between 65438 08℃ and 28℃, because the pistil is the most active and fertile at this time. When the temperature is too low or over 28℃, the pistil is underdeveloped, its activity is not high, and it is not easy to pollinate. Therefore, fruit farmers should be flexible according to the weather at that time.

Matters needing attention in kiwifruit planting

1, processing seeds

If you want to grow kiwifruit, you need to start with the treatment of seeds. After picking ripe kiwifruit, store it in a cool and ventilated place for a period of time. When it becomes soft and mature, peel off the skin, put it in a gauze bag, rub it, wash off all the pulp outside the seeds, and dry it for later use.

2. Grafting seedlings

Kiwifruit is a large dioecious vine, and seedling grafting is also an important link in kiwifruit planting. Therefore, in order to ensure the rooting of its seedlings, it is necessary to graft the seedlings with branches after the seedlings grow up, and expand the seedlings by cutting or layering.
