How to pollinate greenhouse tomatoes? These methods you need to master

Tomatoes are self-pollinating plants. In open-field cultivation, they can be pollinated by wind and insects, but when grown in greenhouses, because the environment is enclosed and lacks the necessary factors, pollination is relatively difficult, which affects the quality and yield of tomatoes. So, in order to improve the quality and yield of greenhouse tomatoes, how should greenhouse tomatoes be pollinated? Follow the editor and take a look.

1. Hormone flower treatment

Hormone flower treatment is using plant growth regulators to break the original hormone balance in tomatoes and form a new balance, so as to facilitate the transport of the original hormones to the flower parts, improve fruit set rate, and increase yield. Common plant hormones include fruit-setting hormone, 2,4-D, gibberellin and other growth hormones. Spray them at a suitable concentration directly onto the flower clusters, or dip the flower clusters into the solution. However, when using them, be sure not to let the solution touch the branches and leaves, so as to avoid abnormal growth of the branches and leaves.

2. Manual pollination

Manual pollination is simple and direct. It means using a brush or cotton swab to collect pollen from the stamens and apply it to the pistils, thereby ensuring precise pollination of the plant. The advantage of this method is an extremely high pollination rate, but the disadvantage is that it is time-consuming and labor-intensive, and it is only suitable for small-area cultivation. If cultivating on a large scale, this method obviously cannot be realized.

3. Vibration pollination

Vibration pollination is using a vibrator to vibrate the flowers, so that the pollen in the flowers quickly disperses, thereby increasing the chance of successful pollination. During the tomato flowering period, use a vibration pollinator to vibrate the tomato flower cluster stems, so that the pollen is released and falls onto the stigma, promoting fruit set. However, you must be careful during operation to avoid injuring the plants and flower clusters.

4. Bumblebee pollination

Bumblebees are highly efficient pollinating bee species for greenhouses, large greenhouses, arched sheds, and open-field crops. They have a large body size, strong collecting ability, and pollinate a wide range of crops. They can collect nectar and pollen from deep-corolla flowers such as tomatoes, peppers, and eggplants, and their buzz pollination effect is remarkable. You can make use of the advantages of bumblebees, such as strong tolerance to low temperature and humidity and weak phototaxis, so they can pollinate greenhouse crops in any season.
