Do not spray the artificial point in our country. Most of the pollination is artificial point, generally do not spray pollination method. Although spray pollination can increase fruit setting rate, it has little effect on improving fruit quality and wastes a lot of pollen.
The low-temperature storage of pollen can survive for 14 days at room temperature, and it can only survive for 2 hours at room temperature above 28°C, but it can survive for 2-4 years at low temperature (0-18°C).
Moisture absorption before use In the night before the flowers are opened, the pollen is spread on the smooth surface of white paper and placed in a damp place near the water tank for 12-20 hours to fully absorb moisture, thus reducing pollen shedding at the point of time. It can also increase the germination rate.
Fruit pollination points
Must be combined with artificial inflorescence in order to remove the inflorescences before the bad results, such as the flower on the back, long shoots top flower buds, buds buds, bud shoots of autumn shoots and some of the flowering branches. After the inflorescence was separated, the apple left the center flower to remove the edge flowers, and the pear leaves 1-2 flowers to sparse the other flowers.
