How to pollinate tomatoes in greenhouse

Tomatoes are self-pollinating plants, which can be pollinated by wind and insects in open-air cultivation, but in greenhouse cultivation, it is difficult to pollinate because of the closed environment and the lack of necessary factors. affecting the quality and yield of tomatoes. So how should greenhouse tomatoes be pollinated in order to improve the quality and yield of greenhouse tomatoes? Come and have a look with the editor.

1. Hormone lighting flowers

Hormone flower is through plant growth regulators to break the original tomato hormones, to form a new balance, in order to facilitate the original transport to the flowers, improve fruit setting rate and increase yield. The common plant hormones are growth hormones such as Fanglu, 2Jing 4murD and gibberellin, which are sprayed on the inflorescence or soaked in the medicine solution according to the appropriate concentration. But when in use, we must be careful not to touch the branches and leaves, so as not to cause abnormal growth of the branches and leaves.

2. Manual pollination

Manual pollination is simple and direct, that is, using a brush or cotton swab to dip the pollen on the stamens to the pistil, so as to ensure that the plant can pollinate accurately. The advantage of this method of pollination is extremely high, but the disadvantage is that it is time-consuming and laborious, and is only suitable for small area cultivation. If cultivated in a large area, this method is obviously impossible.

3. Vibration pollination

Vibrating pollination is to vibrate the flower with an oscillator to make the pollen in the flower float out quickly, thus increasing the chances of successful pollination. In the tomato flowering period, use a vibrating pollinator to vibrate the tomato inflorescence stalk to make the pollen disperse and let it fall on the stigma to promote fruit setting. But you must be careful when operating, so as not to hurt the plant and inflorescence.

4. Bumblebee pollination

Bumblebee is an efficient pollination bee species in greenhouse, greenhouse, arch greenhouse and open-air crops. it has a large individual, strong collecting power and a wide range of pollination crops. it can collect the honey source of deep crown flowers such as tomato, pepper and eggplant, and the effect of sound shock pollination is remarkable. Bumblebees can be used to pollinate greenhouse crops in any season by taking advantage of bumblebees' strong tolerance to low temperature and humidity and poor phototaxis.
