Cucumber is an annual monoecious plant with different plants. Both male and female flowers develop nectaries, which are mainly fertilized by insects such as bees. It is a typical insect-borne breeding. Insect activities are greatly affected by the climate. They are active on sunny days without wind, while the climate activities at low temperatures are weak. Some people may ask how to increase the rate of cucumber pollination? The best method is to combine natural artificial healing to complete cucumber insemination.
Auxiliary insemination method
Picking the open male flowers of the cucumber on a sunny morning, removing the male petals, revealing the anthers of the stamens, then gently spreading the female flower stigma with the male anthers, spreading the pollen quickly and evenly onto the female flowers, assisting the insemination to damage the female flowers, usually 1 Male flowers are used for pollination of 5 female flowers.
Auxiliary insemination time selection
Auxiliary pollination needs to control the time, according to the experience of the best pollination time on the sunny day around 9 am. The melon rate of pollinating cucumbers was significantly lower than 9 am. When suffering from low temperature and rainy weather, it usually only blooms at noon, and then pollinates for a few hours.
Assisted insemination
1. Cucumber insemination encounters precipitation. In the evening before the flowering of cucumber, the male and female flower buds will be covered with a waterproof sleeve, so that the pollen will not be washed away, affecting the quality of insemination.
2, cucumber assisted insemination should take a good time, pay attention to the growth of the female main vine, preferably on the third main man. Auxiliary pollination is usually performed with large petals and full growth. Male flowers should not be used in the field. The male flower buds should be placed in the greenhouse at rest. After the natural bloom, they should be taken out for pollination, so that the amount of pollen is large and the quality is ensured.
3, the stigma of the female flower is generally divided into 3 petals, should be gently spread evenly to avoid the appearance of partial melon.
