Manually dispense the diluted pollen into a dry vial. The vial is tied with a string and hung on the finger. Use a clean brush or a self-made pollinator (the newspaper is cut into paper sticks, try to compact it, and then cut it in the middle. The whole cross-section of the hairy pods is to become two pollinator 蘸 pollen, gently touch the pistil stigma. Each pollen grants about 5 flowers. The artificial roller method can achieve a fruit setting rate of 80%. The material is: a piece of bamboo, a white towel, and a proper amount of filler. First, wrap the towel with stuffing such as old cotton wool, and sew the edge to make it a cylinder. The height is 40-50 cm and the diameter is about 9 cm. Then insert the bamboo raft into the towel bar made by the above method and bind it with a string. The next mouth can be. When the fruit tree blooms 40%, it first rolls on the pollinating tree, so that the towel bar is covered with pollen, and then gently rolls on the flowering cultivar of the main cultivar. The thin part of the flower is slowly rolled and rolled twice; the flowering place is quickly rolled and rolled. Once again. Mechanical spraying should be used for mechanical spraying in orchards with large pollinating area and sufficient pollen amount. The temperature is better at 22°C-25°C. Pollen suspension preparation method: first 500 grams of white sugar, 30 grams of urea, 10 kilograms of water dubbed a mixture of liquid pro-spray dry pollen before adding 25 grams and 10 grams of borax, with 2-3 layers of gauze filter out impurities.
