How to pollinate yew
1. Male pollen collection
When the male flower bud of the yew begins to bloom for the first time, after two days, its flowers will basically be in full bloom, and this is the best time to collect male flowers. First of all, spread its male flowers on white light paper, pay attention to the uniform thickness when spreading, and then find a piece of white paper to cover it. Remember that the smooth surface should be up, and then you can put it in the sun. And remember to turn the male flowers every 2 hours, and 1 day later, you can see the powder. At this time, find a small sieve to gently remove the sundries inside.
2. Pollination time
When pollinating the female plant, you should choose the right time, usually around 9: 00 a.m. or 3: 00 p.m., 2-3 days after the male plant blossoms, when we gently touch the stigma of the male flower with our fingers. If it shows a ribbon-like water belt, then pollination can be carried out, and the pollination success rate is also very high.
3. Pollen treatment
Find water to put the pollen in, and then start to mix evenly, and then add a little borax and sugar, the purpose is to make the pollen more active, so as to improve the fertilization rate.
4. Pollination method
Put the pollen into a sprayer and then use the sprayer for spray pollination; or you can put a small amount of pollen into a gauze bag and make some small holes in the gauze bag, then tie it to a 3-meter-long bamboo pole to pollinate with natural wind; or you can pollinate with wind pollination.
5. Points for attention
In the process of pollination, there may be some problems, such as stigma and pollen activity, stigma activity and surrounding conditions. Either way, if the activity is too low or the environment is too poor, the success rate of fertilization will be greatly reduced, while if the activity is high or the environment is suitable, it will greatly improve the success rate of fertilization.
