The first is the selection of pollination varieties. Peach-pollinated varieties. Here we generally use Shuguang nectarine as the main flower. Its early flowering period, large amount of pollen and strong affinity have the best effect of 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 choose a robust growing nectarine tree, picking the buds to be put into the pods, and rubbing the pods in time to remove the anthers from the stamens, then sieving them with a fine sieve to remove impurities such as petals. The anthers were thinly spread on newspapers and placed in a dry indoor place. The room was dry, ventilated, dust-free, and the temperature was controlled at 20-25°C. The temperature is too low, the anther is not easy to crack, loose powder speed is slow; the temperature is too high, affect the vitality of pollen. Be careful not to expose the anther to sunlight. After 24 hours, dried and cracked anthers were finely crushed to remove gold and yellow pollen. Put the pollen into a brown glass bottle and store it in a refrigerator below 0°C.
The third is pollination. There are two ways: One is the artificial point method. First, prepare a 5cm-long bicycle valve core. One end is put on a matchstick and one end is rolled back by 0.5cm. Choose sunny and windless weather and conduct pollination at 10am to 3pm. One point pollinator valve core is used to draw pollen at one end and is given to the stigma of the newly opened flower. Pollen can be pollinated for 3-4 flowers per pollen. The newly opened flower petals are fresh, and the stigma has mucus. At this time, the pollination is easy to fertilize and the pollination effect is better. Pollen should be used with it, and it should be replaced when not in use. The amount of pollination depends on factors such as the size of the tree, the vigor of the tree, and the level of technical management. It generally requires pollination 3-4 times.
In addition, artificial dusting can be used. Mix the pollen with clean and free of talc or fine dry starch in a ratio of 1:10-20 and mix it evenly in the gauze bag. Fix the gauze bag on the top of the long bamboo basket and shake it on the canopy of flowering period to make Pollen flies on the stigma, which improves fruit set.
