In the zucchini sitting melon early, if the lack of water and fertilizer, then it is very easy to lead to zucchini sharp mouth melon, in the later stage is easy to appear thin waist melon, but water and fertilizer should not be too much, otherwise it is easy to form big belly melon. Moreover, if the pollination is poor and the pollen is unevenly distributed, it will lead to a depression in the parts where the pollination is insufficient. Then there is the temperature. Too high and too low temperature will affect the photosynthesis of zucchini, resulting in insufficient nutrition. Finally, the defect of female flowers or bisexual flowers will cause progress.

II. Prevention and control methods

1. Fertilizer and water management

Zucchini has a large demand for fertilizer and has a very strong ability to absorb fertilizer. Although it has strong drought tolerance, it needs a lot of water during the fruit expansion period, so we should pay attention to keep the soil moist. At the same time, it is necessary to apply sufficient base fertilizer, combined with an appropriate amount of nitrogen and potassium fertilizer for topdressing work. Every time after picking melons, we should pay attention to topdressing once, the base fertilizer is mainly farm manure, with the right amount of cake fertilizer, phosphate fertilizer and so on. The moisture in the field should be controlled to dry in the early stage and keep moist in the fruiting period.

2. Temperature control

When planting zucchini, if it is precocious, then generally the plastic film greenhouse should be used to cover the small shed for heat preservation work. The suitable temperature for the growth of zucchini is generally about 20-30 degrees. Among them, the optimum temperature is about 20 degrees, and the soil temperature should be kept in the range of 18-23 degrees. So when we plant zucchini, we should adjust the temperature appropriately according to the change of weather. Reasonable uncover the film, especially pay attention to adjust the temperature according to the change of temperature and the temperature requirements of zucchini, promote the accumulation of nutrients and reduce the phenomenon of abnormal melons.

3. Artificial pollination

In addition, we have to carry out artificial pollination. Every morning around 9: 00 a. M., usually the zucchini male flowers bloom peak period, when the male flowers will be removed, and then take out the Corolla. When the anther is sprinkled on the style of the female flower, one male flower can pollinate about three female flowers. It is best to be able to carry out when the air humidity is high, which can improve the effect of pollination. Pollination should be uniform, and hormone treatment can be used to protect the fruit. Apply it to the pedicel or ovary with chemicals such as 24 days, but do not touch the stems and leaves.

The above is a brief introduction to the prevention and control methods of zucchini malformed melon. That's all for today's introduction. This article is for reference only. I hope it can help you all.
