Prepare a brush or a clean brush for artificial pollination.After its flowers open, the stamens inside will naturally emit pollen, and then use a brush or brush to dip the pollen on the stamens, and then brush on the stigma, so as to spread pollen, pollination can be successful.It is better to choose noon on sunny days, so that the pollination effect will be better.
When pollinating artificially, you can also use an electric oscillator, which will cause the tomato to vibrate after contact with it, so that the pollen on the stamens will fall down and help pollinate.
Open-air planting is mostly pollinated by insects and wind, and the fruit setting rate is also very high.However, greenhouse planting can not be carried out by wind, and insects are relatively few.With the help of bumblebees or other bees, a large number of bees can be released in the greenhouse, so that bees will help pollination, the effect is also very good, this method is more commonly used.
It is very sensitive to temperature during flowering, so we should pay attention to temperature control.The best temperature is 24-26 degrees during the day and 12-14 degrees at night.Especially 5 days before flowering and 3 days after flowering, the temperature during this period can not be higher than 30 degrees or lower than 12 degrees, otherwise it will affect pollination and fertilization.In addition, the early flowering period should be pruned, and the big flowers on the first spike should be knocked out, which will affect the fruit setting of other flowers.
