When is the best time for pollination of watermelon?

The best time for watermelon pollination is on a sunny day, usually the Corolla begins to loosen at about 5: 00 in the morning, pollen spreads out at about 6: 00, and the Corolla unfolds completely. 8-10:00 in the morning is the time when the pollen physiological activity of female and male flowers is the most exuberant, so this is the best time for artificial pollination, no later than 12:00 at noon.

When the watermelon is pollinated, the artificial pollination time of watermelon is usually 7 days, and the longest is no more than 10 days. If pollination is finished within 7-10 days, the fruit setting period is centralized, the management is convenient, the harvest time is concentrated, and the fruit size is uniform and the yield is high. Such as more than 10 days, relatively irregular melon, resulting in inconvenient management, uneven fruit size, harvest time is not concentrated, the yield is also affected.
