Fruit tree artificial pollination points

The inflorescences of the defective parts must be removed before the artificial flowering inflorescences are separated, such as the inflorescences of the flowers on the back, the buds of the long branches, the buds of the buds, the flower buds of the autumn shoots, and the partial inflorescences of the stalks. After the inflorescence is separated, the apple leaves the center flower to remove the flowers, and the pear leaves 1-2 flowers to remove other flowers.

Manually do not spray in China, most of the pollination is artificially taught, generally do not use spray pollination. Although spray pollination can increase the fruit setting rate, it has little effect on improving fruit quality and wastes a lot of pollen.

The cryopreserved pollen can survive for 14 days at normal temperature in the flowering stage, and can only survive for 2 hours at room temperature above 28 Â°C, but can survive for 2-4 years at low temperature (0-18 Â°C).

Moisture absorption before use on the night before the flower bloom, put the pollen on the glossy surface of the white paper, and put it in the damp place near the water tank for 12-20 hours, so that it is fully hygroscopic, which can reduce the pollen detachment when the point is given. It can also increase the germination rate.
