Recently, some vegetable farmers have reported that the greenhouse squash has fallen and fallen fruit, and I do not know how to prevent it. The control measures for the fall of the fruit of the zucchini are summarized, for the reference of farmers: 1. Temperature control in the shed: During the flowering period of zucchini, the temperature is controlled at 22 to 26 °C during the day and 15 to 18 °C during the night. The temperature difference between day and night is increased, nutrients are accumulated, and the fruit is expanded. The temperature control is mainly to uncover the grasshoppers and timely ventilation. 2. Illumination control in the shed: promptly uncover the straw curtain, extend the illumination time as much as possible, and increase the light intensity. Wipe the grass and dust on the shed film in time to increase the light transmittance and increase the temperature. 3. Strengthen water and fertilizer management: If the leaves of the plant are rich in green and thick, the flowering will not result, and the boron fertilizer will be added in time. When the flower buds are first appeared in the zucchini, the chlorophyll or spray Shibao is sprayed once every 10 days to prevent boron. Insufficient trace elements cause flower and fruit dysplasia and fall and fall, and use large clods to hold the vines and inhibit the plants from growing wild. If the plant is thin and the leaves are yellow and thin, it is necessary to increase the water and fertilizer, remove the first female flower, and promote vegetative growth. 4, to prevent poor fertilization: 蘸花ä¿æžœ is the main measure to prevent fertilization and fall flowers and fruit, using artificial pollination or treatment with hormones such as anti-fallin, in order to ensure that the melon. The method is to pick up the male flowers that are open on the same day at around 10 am, remove the corolla, gently smear on the female stigma for artificial pollination, or select the female flowers to be opened, and smear the female flowers with 2,4-D scented flowers at a concentration of 20 ppm. Stigma and melon handle promote fruit enlargement and prevent poor fertilization. 5, timely control of pests and diseases, clearing branches and leaves: pests and diseases are another cause of the fallow flowers and fruit drop, timely control of pests and diseases, strengthen ventilation, reduce the humidity inside the shed, regularly apply pesticides, remove fallen petals and old leaves of diseased leaves . In addition, a layer of carbendazim powder is applied to the top of the petals of the zucchini fruit to prevent the bacteria from invading the fruit and causing the fruit to fall off.
