Choose flower-picking varieties and plants Choose varieties with strong affinity with the main planting varieties as flower-picking pollinating varieties; the amount of flowers in the plant should be large, which does not affect its own yield.

The suitable time for picking flowers is 2-3 days before pollination; collecting bell flowers or initial flowering, mainly edge flowers.

The flowers collected from the anthers are breathable and can not be stacked. Collect the pollen in the room in time. The two flowers rub together and the anthers fall to remove debris.

Take the pollen, spread the pollen evenly on the paper, bake it in the ondol or in the conservatory at 20 ℃ ~ 30 ℃, the anther breaks apart in 1-2 days, and the pollen is taken out.

Pollen storage Put the inflorescences of fresh male flowers in a ventilated and dry room at 25 ° C and spread them thinly on white paper, air dry until the pollen sac splits, sieve the scattered pollen to remove debris, branches, leaves and other debris. Then put it in a dryer or a container with raw ash, or put it in a refrigerator or cold storage for later use.

Pollen filler To reduce the cost of pollination, a certain amount of pollen filler must be added to the pollen before artificial pollination.

Pollination method

When the artificial pollination blooms to more than 50% in the center of the fruit tree, point pollination can be carried out on the day of blooming, which can be done with a brush, eraser pencil, cigarette filter, or pollination gun. It should be noted that when pollination, the central flowers of the lateral and lower inflorescences should be spotted, and the mid-short branch top flower must not be spotted too much on one branch.

Wall bees pollinate wall bees when they bloom more than 50% in the center, with 400 to 500 bees per mu.

Liquid pollination artificial pollination has a high fruit setting rate, but the work efficiency is slow. The use of liquid pollination can greatly improve the work efficiency and has been widely used in recent years. It can be prepared with 5 kg of water, 15 g of urea, 15 g of borax, 250 g of sucrose, and 15-20 g of dry pollen. It is the best time for the first liquid pollination when more than half of the trees in the orchard have more than 60% of the central flowers open It can be sprayed once a day for three consecutive days, and it is ready for use.
