In production, pollination is the key to improving commodity rates and reducing the number of malformed fruits. Conditional growers should stock bees, one box per acre, the total number of bee colony is more than 30,000, bees should be placed in the shed 3 to 5 days in advance, placed in the southwest corner, the box mouth to the northeast corner. When the bees like to dry, they should pay attention to dehumidification. Apply the gauze cover to the air outlet during the day to prevent the bees from escaping.
In the absence of bees, artificial pollination can be carried out. The method is to fan the dew on the leaves of the strawberry with a fan after 10 o'clock in the morning to reduce the humidity on the flowers and leaves and help the cracking of the anthers. The day (or the next day) is selected. ) Spend the flowers in the open position, apply a small row of pens to the top of the flower receptacle after two rounds, and then click on the top of the receptacle to make the whole receptacle pollinate evenly. The stigma of the pistil is green before pollination, becomes yellow after pollination, darkens after fertilization, and the style falls off after the fruit begins to expand. Pollination can also eliminate the small ineffective flower buds that formed in the late. Eight fruits per sequence can achieve the desired yield, and pollination varieties can also be configured. Two to three varieties can pollinate each other, which can help reduce the deformed fruit and increase fruit size. .
