Artificial pollination method of dragon fruit

Fire dragon fruit is very popular in our daily life. So now there are more and more people growing in our country, when planting dragon fruit, if we let it pollinate naturally. Then its pollination and fertilization rate will be relatively low, and it will also affect the yield of dragon fruit. So we need to do artificial pollination. So how to pollinate dragon fruit artificially? Let's take a look at the method of artificial pollination of dragon fruit with Xiaobian.

1. Why do you need artificial pollination

Under normal circumstances, the stamens and styles of dragon fruit flowers are equal or short. For example, stamens will be about 4 cm shorter than stigma, so if self-pollination, the success rate is very low. And dragon fruit is a kind of plant that blossoms at night, the flowers will wither after being exposed to the sun, and there are basically no insects to help pollinate at night. If it is planted red flesh dragon fruit, then it is very easy to appear self-pollination incompatibility, and the self-pollination rate will not exceed 10%. Finally, if it is planted in a solar greenhouse, it is difficult to pollinate because of the wind.

2. Pollination time

When we pollinate artificially, we should pay attention to judge the pollination time according to the flowering law of dragon fruit. The dragon fruit usually blossoms at night, and the flowering time is not long, basically only one night or so. Therefore, the time of artificial pollination of dragon fruit should be carried out from the evening to the morning when the flowers gradually close. It is best to pollinate at one o'clock in the morning, because at this time the dragon fruit flower has the largest flower diameter and the highest pollination success rate. However, because it is night, artificial pollination will still be inconvenient to operate.

3. Pollination method

Pollination can be done by the simplest brush point method. Because the dragon fruit flowers are relatively large, and each flower has more pollen, so the pollen collection is also very simple. However, it should be noted that the vitality of pollen is relatively poor, in the room temperature environment, the survival time is generally not very long. Therefore, in artificial pollination, it is best to use the pollen at random to ensure the vitality and pollination effect of the pollen. After the pollen is collected, the pollen is directly dipped with a brush and then smeared evenly on the stigma.

4. Points for attention

If the dragon fruit varieties are different, then the genetic difference between them will be very large, and the pollination rate will be higher. So when we plant dragon fruit, we can plant some different varieties of dragon fruit appropriately. In particular, it can be mixed with red meat and white meat, and its fruit rate can be effectively improved. Then in artificial pollination, we should also pay attention to the amount of pollen on the stigma. The more the amount of pollen on the stigma, the larger the pitaya fruit will be, so we should also pay attention to control the amount of pollen when pollination.

The above is a brief introduction to the method of artificial pollination of dragon fruit. That's all for today's introduction. This article is for reference only. I hope it can help you all.
