1、 How to pollinate artificially

A brush or a clean brush can be prepared for artificial pollination. After its flower organ opens, the stamens inside will naturally emit pollen. Then dip the pollen on the stamens with a brush or brush, and then brush on the stigma. In this way, the pollen can be transmitted and pollination can be successful. Note that it is best to choose noon on a sunny day, so that the pollination effect will be better

An electric vibrator can also be used for manual pollination. Contact with the tomato will cause it to vibrate, so that the pollen on the stamens will scatter, which can help pollination

2、 How to pollinate the plants planted in Greenhouse

Most of the plants planted in the open air are 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 there are few insects. With the help of bumblebees or other bees, a large number of bees can be released in the greenhouse, so that bees will help pollinate, and the effect is also very good. This method is commonly used

3、 Flowering management

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 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, it is necessary to prune at the beginning of flowering, and the large flowers on the first spike will be knocked off, which will affect the fruit setting of other flowers
