The pollination method of peach trees is fast and good.

Artificial pollination and artificial pollination can be used. Although peach trees can bear fruit by self-pollination, peach trees with cross-pollination have high fruit setting rate, good quality and high yield. When cultivated in greenhouse, the possibility of cross-pollination is very small because of poor air mobility, low temperature and high humidity in greenhouse. Therefore, in the cultivation of peach trees in greenhouse, it is necessary to carry out auxiliary pollination to improve the yield and quality of peach.

I. artificial pollination

1. Anther collection. The big bud buds of pollinated peach trees were collected 1-2 days before flowering of the main varieties. Break the bud, gently put the anther on the smooth paper with the index finger of the right hand, and bake it under a 40w incandescent lamp for 12 hours. The anther is 30cm away from the light bulb, not too close to prevent the anther from being burned by excessive temperature and inactivating the pollen. After the pollen grains are dispersed, put the anther in a clean and dry glass bottle, fasten the mouth of the bottle with a plastic bag and put it in the freezer (if possible, it can be put in the dryer). Be sure to dry the anther, otherwise the anther in the bottle is easy to mildew and inactivate.

two。 Pollination method. Choose the flowers that are in full bloom on the peach tree. from 9 a.m. to 3 p.m., dip the rubber head on a clean, soft brush or eraser pencil into the pollen and click on the stigma of the flower.

2. Honeybee pollination

1. The number of bees released. Generally, there are 1-2 boxes of bees in every half-mu solar greenhouse, which can not make every flower pollinate in time and normally, and many bees waste the source of bees and increase the cost of production.

two。 Time to enter the shed. A week before the peach tree blossoms, put the beehive in the greenhouse in the evening or at night, so that the bees can be better familiar with the environment in the greenhouse.

3. Put it in position. The beehive is placed in the middle of the greenhouse. if you put two hives of bees, the distance between the two hives is about 10 meters, and things are placed side by side. The beehive is about 50 cm from the ground to prevent the beehive from getting wet.

4. Colony management. After the pollination hive is placed, do not open the nest door immediately. Wait 5-6 hours after the colony settles down, and then slowly open a small opening, small enough to squeeze two bees. Two days later, the bees gradually adapted to the environment in the greenhouse and went out of the box to collect honey to pollinate peach trees.
