In order to promote the high-quality fruit of zucchini, the vegetable farmers should create a good ecological environment during the cultivation process, improve management techniques and prevent the appearance of malformed fruit. The following is the reason and prevention method of using the hormone-controlled products to cause deformed fruit. The zucchini is deformed. The reasons are:
- Insufficient water and fertilizer: It is easy to form a long-nosed melon in the early stage of sitting melon, and it is easy to form a thin waist melon in the middle stage. If the medium-term fertilizer is too strong, it will easily form a big belly.
- Poor pollination, uneven distribution of pollen, and the area where the pollination is insufficient is concave.
- Too high or too low temperature will affect the photosynthetic efficiency, making the production of nutrients insufficient and inhibiting fruit development.
Prevention:
- Meet water and fertilizer requirements. Zucchini requires more fertilizer and stronger fertility. First, the base fertilizer should be applied. Second, nitrogen and potassium should be combined with timely topdressing. Each batch of melon should be topdressed once. The field moisture in the early stage is mainly controlled by the stem, and the wet management should be maintained during the period.
- Perform artificial pollination. Every day from 8 to 10 o'clock in the morning, the peak period of male flowers is open. The male flowers should be taken and the corolla should be removed. The anthers should be gently cast on the stigma of the female flowers. One male flower can give three female flowers. When the air humidity is high, the pollination effect is better. it is good.
- Pay attention to the regulation temperature. The adaptable temperature range of zucchini is 15 °C ~ 38 °C, and the optimum temperature range for growth and development is 18 °C ~ 25 °C. Therefore, it is necessary to adjust the time of uncovering the membrane according to the climate change situation, especially to change the temperature requirements for temperature management, which is more conducive to accumulating nutrients and reducing consumption.
