How do greenhouse peach blossoms pollinate?
How should the peach trees in the greenhouse pollinate when they blossom? When planting peach trees in greenhouse, in addition to configuring pollination trees according to a certain proportion, it is also necessary to release bees at flowering stage or artificial pollination to improve fruiting strength and strive for high and stable yield. 1. The first step of artificial pollination is to collect pollen. 2-3 days before pollination, flower buds of other early flowering varieties in greenhouse are collected, anthers are picked, mixed and placed in a ventilated place to dry, and the temperature is kept at 20-25 ℃. After the anther cracked and released the pollen, put it into a dry vial to avoid light. Pollinate peach trees when they are in blossom. The best time for pollination is 9-16:00, using a brush or rubber head to dip the pollen point onto the newly opened pistil stigma. The flowering period in the facility is longer, usually about 10-15 days, and it is best to pollinate the new flowering once a day. 2. Better pollination effect can be obtained by putting 1-2 boxes of bees per mu in greenhouse. Although some peach varieties have high self-pollination rate, but the greenhouse environment is special, there is no wind, no insects, natural pollination is limited, therefore, it is necessary to create suitable pollination environment. For example: the use of mechanical (electric fan) wind pollination; release bees, wall bees, pollination; artificial pollination. More peach tree planting techniques
