The latest artificial pollination of Gastrodia elata

Gastrodia elata is a commonly used medicine, which is mainly used to treat diseases such as wind, shock, dizziness, headache, hemiplegia and so on. At present, the main producing areas of Gastrodia elata in China are Jilin, Hebei, Hubei, Sichuan, Guizhou and other places. In the process of planting, generally artificial Gastrodia elata needs artificial pollination, so how do we carry out artificial pollination? Why artificial pollination? The editor will tell you next.

1. Reasons for artificial pollination of Gastrodia elata

Wild Gastrodia elata is basically pollinated by rare soil bees in nature, and the success rate of pollination is not high. The artificial cultivation of Gastrodia elata has a larger area, so it naturally cannot rely on soil bees for pollination, and the flowers of Gastrodia elata are unique and must be pollinated with the help of external forces. In order to obtain high quality planting and increase seed yield, it is necessary to use artificial pollination, which is the main reason why Gastrodia elata needs artificial pollination.

2. The time of artificial pollination

You should grasp the time of artificial pollination, or you will miss the best ten minutes. Under normal circumstances, we complete pollination within one to three days after flowering, when the pollen tuber is mature and exuberant. Pollination at this time can ensure the seed setting rate of Gastrodia elata. Pollination too early and too late will reduce yield and affect quality. The second is to choose pollination between 10: 00 a.m. and 4: 00 p.m. on a sunny day, not earlier than 10: 00 or later than 4: 00.

3. The method of pollination

The tools we need to pollinate are usually sharp-nosed tweezers, of course, needles or bamboo needles can also be used. When pollinating, you should hold the receptacle of the flower left and right, and then hold the forceps or needle in your right hand to clip or press the lip of the flower to let the pistil protrude, and then use the pollination tool to pick the cap of the flower from the bottom up, stick the pollen block, and put it on the pistil, which can be pollinated by the same plant, different plants and different varieties of Gastrodia elata, which is also a way of hybridization. At the same time, we can also experiment to find out which kind of output and quality is better.

4. Points for attention

In the artificial pollination of Gastrodia elata, we need to pay attention to some smaller details, let's take a look. First of all, we should pay attention to the time of pollination. We must wait for the pollen to mature before pollination. At the same time, we should not pollinate on rainy days or when the dew is not dry. The second is not to hurt the gynostemma when clipping off the lip, and not to stab the ovary at the bottom of the flower when picking a flowering cap. In addition, it is best to use cross-pollination, which can produce new varieties and improve the quality of future generations. Finally, the pollen is better when pollinating, and it is best to stick with the mucus.

The above is the editor for everyone to understand the problem, carried out a simple and general analysis, but also sorted out about Gastrodia elata artificial pollination of some points for attention, hoping to help friends.
