Tomatoes are one of our common vegetables. There are many farmers who grow tomatoes. Everyone knows that in the process of planting tomatoes, if the fruit falling in the early stage is serious, it will lead to low yield of tomatoes in the later stage. An important part of the high yield of tomatoes is the preservation of flowers and fruits. The most important of these is pollination. Now that tomatoes are grown in open-air and greenhouses, what are the pollination methods for these two methods of planting? Let's take a look.
How do tomatoes pollinate? What is the difference between open-air and greenhouse cultivation?
1. Pollination method for planting tomatoes in the open air
Tomatoes are self-pollinating plants. In the case of open-air cultivation, artificial pollination is not required, and it is only necessary to let them normal pollination.
1. Adding boron fertilizer
In the pollination stage, in order to increase the probability of successful pollination, a certain amount of boron fertilizer needs to be sprayed by foliar fertilization because it can enhance the activity of the pollen and promote the elongation of the pollen tube.
2, combing flower spikes
Before pollination, the flower spikes need to be sorted, and the first open flower and the flower on the tip of the ear are removed to ensure that the entire flower head can be evenly opened and more pollen is released.
3, protect the blade
In the pollination period of plants, it is necessary to strictly protect the leaves, improve the photosynthesis of the plants, and make the pollen have stronger activity. Specifically, enzyme fertilizers and amino acids can be used to achieve the effect.

Second, pollination methods for growing tomatoes in greenhouses
Tomatoes pollinated in greenhouses are in a confined space, there is not enough wind to spread pollen, and there are no natural insects for pollination. Therefore, it is more likely that pollination will result in poor quality and yield.
1, human pollination
Human pollination is the most straightforward way to use the brush or cotton swab to rub the pollen on the stamens onto the pistil to ensure accurate pollination. The shortcomings of this method are obvious, that is, it takes time and damages manpower, and is only suitable for small plantations or indoor planting.
2, hormone pollination
Hormone pollination is the use of 2,4-D liquid to stimulate plant pollination. Hormone pollination can be sprayed on the inflorescence or the inflorescence can be soaked in the liquid. Although this method is faster than manual pollination, it is necessary to pay attention to the fact that the liquid cannot touch the branches and leaves of the tomatoes to prevent the leaves from growing abnormally.
3. Vibration pollination
Vibration pollination uses an oscillator to vibrate the flowers, allowing the pollen in the flowers to quickly dissipate, increasing the chances of successful pollination. This pollination method has no obvious damage to the plants, but the efficiency is still not enough, and it is not suitable for large-scale plantation.
4, bumblebee pollination
Bumblebee pollination is the manual placement of beehives in greenhouses to help tomatoes pollinate insects. This method of pollination is extremely convenient, basically no need to worry about and the pollination rate is extremely high, and it is possible to rent different numbers of bumblebees according to the planting area, which is widely applicable to various plantation fields. Of course, the cost of bumblebee pollination is high and needs to be considered.
