Causes and control methods of zucchini malformed melon

In the cultivation and production of zucchini, abnormal melons often occur, which seriously affects the yield and quality of zucchini and causes economic losses to farmers. So what is the cause of zucchini malformation? What about prevention and control? Let's take a look.

1. Imbalance of fertilizer and water

In the initial stage of zucchini fruit setting, if there is not enough fertilizer and water, it is easy to form pointed melon; in the middle stage, it is easy to form thin waist melon; in the later stage, it is easy to form slender and crooked melon, so fertilizer and water management is very important.

Prevention and control methods: in the fruit setting period to meet its fertilizer and water demand, must apply sufficient base fertilizer, in reasonable topdressing, at the same time, we should often water, keep the soil moist, ensure the supply of fertilizer and water, but also pay attention to the supply, too much fertilizer and water will also cause deformities.

2. Poor pollination

In the environment of low temperature, high humidity or high temperature and drought during pollination, coupled with fewer pollinating insects such as bees, it will often lead to poor pollination quality and uneven distribution of pollen, which will form malformed melons.

Control method: in the zone of artificial reproduction and pollination, at about 9 o'clock in the morning, pick male flowers, remove the Corolla, and gently put the anther on the style of female flowers. Generally, a male flower can pollinate 3-4 female flowers.

3. Temperature discomfort

If the temperature is too high or too low in the fruit stage, it will have a great impact on plant photosynthesis, resulting in insufficient nutrient synthesis, resulting in insufficient nutrient growth of the fruit, resulting in deformities.

Prevention and control methods: pay attention to the control of temperature, early-maturing varieties can increase temperature and keep warm in greenhouse or greenhouse, zucchini can adapt to the temperature of 15-38 degrees, and the suitable temperature for growth is 18-25 degrees, so it is necessary to adjust the application of uncovering film according to the change of air temperature.

4. Flower problem

The fruit formed by the imperfect female flower or bisexual flower of zucchini is easy to form deformed fruit because of poor flower bud differentiation under low temperature or weak light.

Prevention and control methods: this situation is less, the frequency is not high, if this situation occurs frequently, it is necessary to change varieties in time.

The above is the introduction of the causes and prevention methods of zucchini malformed melon. I hope it can help you. If you want to know more about it, please pay attention to us.
