My family only raised a sunflower, and there was no planting around it. Now the disk is big. How can we finish the pollination? Can pollination bear fruit?
Sunflower is a crop of cross pollination, self pollination rate is extremely low, artificial pollination can improve the seed setting rate, yield increased significantly.(1) the time of pollination in sunflower in the blooming stage (full field 70% 2~3 days after flowering), first artificial pollination, 1 times every 3 days after pollination, pollination is the best pollination time was 2~3 times, after the morning dew fell down to the end of 11. If the morning is not over, you can do it later than 15.(2) there are two kinds of artificial pollination methods. A puff of pollination. With one hand holding the sunflower disc neck, with the other hand puff (pollination tool made of soft cloth and cotton) positive touch disk, the sticky pollen grains in the puff, contact do not force too much, so as not to damage the stigma. Then use the same method to puff lightly touching another disk, in order to wipe down. Because the sunflower flowering is from the outside to the inside, to make fresh pollen pollination in the flowering flowers, the more number of such pollination, the pollen grains of mixed sticky puff more, choose more opportunities for pollination, pollination effect is better. The two is disc contact pollination, that is, in the adjacent two rows, during the flowering period, the disc is pressed against each other by hand by hand, which acts as a pollination. Use this method to make it light, so as not to strain and break the disc neck.
Natural pollination of flowers, wind, insects
You must mate with flowers before you can bear fruit
