Peach blossom artificial pollination

Followed by the preparation of pollen. 2-3 days before pollination is the best time to make pollen. The specific method is to select a healthy sapling nectarine tree, pick up the flower buds containing the mites to be placed, promptly rub the anthers out of the stamens, and then use a fine sieve to remove the impurities such as petals. The anthers are thinly spread on the newspaper and placed in the room to dry, the room is required to be dry, ventilated, dust-free, and the temperature is controlled at 20-25 °C. When the temperature is too low, the anther is not easy to crack, and the powder is slow; the temperature is too high, which affects the vitality of the pollen. Be careful not to expose the anthers to the sun. After 24 hours, the dried anthers were finely pulverized, and the impurities were removed to obtain golden yellow pollen. Put the pollen in a brown glass bottle and store it in a refrigerator below 0 °C for later use. Linyi Fertilizer Network Copyright

The third is pollination. There are two methods: one is the manual method. First, prepare a 5 cm long bicycle valve core, one end is set on the match stick, and one end is rolled back 0.5 cm, and the pollinator is finished. Choose sunny and windless weather and conduct pollination from 10 am to 3 pm. Use the pollinator valve core to pick up the pollen at one end and point it to the stigma of the newly opened flower. Each time the pollen can pollinate 3-4 flowers. The newly opened flower petals are fresh and there is mucus on the stigma. At this time, the pollination is easy to be fertilized and the pollination effect is better. Pollen should be used as needed, and returned to the original place when not in use. The amount of pollination depends on factors such as the size of the tree, the strength of the tree, and the level of technical management. It is generally required to pollinate 3-4 times.

In addition, manual dusting can be used. Mix the pollen with clean and impurity-free talcum powder or fine dry starch in a ratio of 1:10-20 and uniformly put it into the gauze bag, fix the gauze bag on the top of the long bamboo pole, and then shake it on the crown of the flowering period. Pollen flies down on the stigma, which increases the rate of fruit set. Linyi Fertilizer Network Copyright
