And an important link of tomato high yield is to protect flowers and fruits.
The most important thing is pollination.
Now planting tomatoes is divided into open-air planting and greenhouse planting. What are the pollination methods of these two planting methods? Let's take a look.
First, the pollination method of tomato planted in the open air
Tomatoes are self-pollinating plants. In the case of open-air cultivation, they don't need artificial pollination, just let them pollinate naturally.
1, adding boron fertilizer.
In the pollination stage, in order to improve the probability of successful pollination, a certain amount of boron fertilizer should be sprayed through foliar fertilization, because it can enhance the activity of pollen and promote the elongation of pollen tubes.
Step 2 comb the ear
Before pollination, the flower spike should be arranged, and the flowers that bloom first and at the tip of the spike should be picked to ensure that the whole flower spike can bloom evenly and release more pollen.
Step 3 protect the blade
During pollination, it is necessary to strictly protect the leaves, improve the photosynthesis of plants, and make the pollen more active. Specifically, enzyme fertilizers and amino acids can be used to achieve the effect.
Second, the pollination method of tomato planted in greenhouse
Because tomatoes pollinated in greenhouse are in a closed space, there is not enough wind to spread pollen, and there are no natural insects to pollinate, which is easy to pollinate poorly, leading to the decline of furrow application quality and yield.
1, artificial pollination
Artificial pollination is the simplest and most direct way, which is to dip the pollen on the stamens into the pistil with a brush or cotton swab to ensure that the plants can pollinate accurately.
The obvious disadvantage of this method is that it is time-consuming and laborious, and it is only suitable for small plantations or indoor planting.
2. Hormone pollination
Hormone pollination is to stimulate plant pollination with 2,4-D liquid medicine.
Hormone pollination can be carried out by spraying inflorescences or soaking inflorescences with liquid medicine.
Although this method is faster than artificial pollination, it should be noted that the liquid medicine must not touch the branches and leaves of tomato to avoid abnormal growth of branches and leaves.
3. Vibration pollination
Vibration pollination is to vibrate the flowers with an oscillator, so that the pollen in the flowers can float out quickly, thus increasing the chances of successful pollination.
This pollination method has no obvious harm to plants, but its efficiency is still not enough and it is not suitable for large-scale planting.
4, bumblebee pollination
Hummingbee pollination is to artificially place beehives in the greenhouse to help tomatoes pollinate insects.
This pollination method is very convenient, basically does not need to worry about, and the pollination rate is also very high. Moreover, different numbers of bumblebees can be rented according to the planting area, which is widely used in various plantations.
Of course, the cost of bumblebee pollination is high and needs to be considered.
To sum up, it is about the pollination method of tomato planting. At present, tomatoes have been widely planted in various places, but there are many problems caused by pollination during the planting process.
Therefore, farmers who grow tomatoes must master the above pollination methods in order to increase tomato yield.
