Why do some cucumbers have flowers but no fruit?

Some farmers planted cucumbers only see the flowers, not see the melon. The reason for this is mainly due to the cucumber plant cell division disorder, resulting in only open male flowers and not open female flowers, so it is not easy to melon. When the cucumber plant branches and leaves vine development strong, can strengthen its tiller hair fork ability, female and male flowers can also be in the same plant body evenly open. If the cucumber plant in the growth process vine disorder crazy long, will destroy the cucumber plant body branching ability, resulting in the plant only open male flowers do not open female flowers, or only at the tip of the vine to open a limited number of female flowers, which will seriously affect the yield of the cucumber and earnings.

　　Flowers without melon cucumber, plants only open male flowers do not open female flowers and caused by the key points of the melon, is to strictly control the melon vine growth, cucumber plant body grows thick and strong, in order to strengthen the cucumber plant body “outside of the section of the branch” and female and male flowers with the ability to open. Specific method is: when the cucumber plant grows more than 4 true leaves, melon vine grows about 30 ~ 40 cm long, per mu of land with plant growth regulator ethylene glycol three-tenths of a dilution, or naiacetic acid, thirtysixths of an alcohol 5 ~ 10 grams, or 10 grams of auxin (any one of the above agents can be), and then on the water 50 ~ 70 kilograms and stirred, in the cucumber plants evenly sprayed 1 ~ 2 times to solve the problem of cucumber due to only the male flower and the “male flower”. Male flowers and the problem of “sterility” caused by the cucumber.
