What is the reason for gourd melons

Zucchini melon is a common physiological disease in the growth process of zucchini. Generally speaking, within 3 days after the female flowers bloom, the young melons will appear chlorosis and yellowing, becoming thin and soft. Melon expansion is obviously blocked, began to shrink, basically lost the commodity value, leading to rotten melon and so on. So what are the main reasons for the watermelon? Today, the editor will give you a brief introduction. Let's take a look at it.

1. Temperature

Temperature is the main cause of watermelon. During the growth of zucchini, the temperature exceeds 35 degrees during the day and higher than 20 degrees at night. It will seriously affect the photosynthesis of zucchini and strengthen the respiration of zucchini. Stems and leaves receive a large amount of carbohydrates, resulting in zucchini vines overgrowing, malnutrition and other problems, resulting in zucchini melons. But the temperature should not be too low, less than 20 degrees during the day, less than 10 degrees at night, then it will also affect the absorptive capacity of the roots, which will also cause melon phenomenon.

2. Lighting

Light is very important for the growth of zucchini. Especially in the zucchini blooming period, if you encounter continuous rainy days, the natural light time and intensity will decrease significantly. And the temperature difference between day and night is small, which affects the photosynthesis of zucchini. The nutrition consumed by the whole plant far exceeds the nutrition produced by zucchini, resulting in melons due to lack of nutrition.

3. Density

Planting density is also a reason for watermelon. When planting zucchini, if the planting density is too high, then the zucchini plants will compete with each other to affect the growth. The aboveground parts will also compete for growth space with each other. Once the leaf area of zucchini reaches more than 4, it will reduce the permeability of zucchini plants, and also inhibit the photosynthesis of zucchini, consume too much nutrition and increase the rate of melons.

4. Pollination

During the zucchini blooming, if the zucchini is poorly pollinated or there is no artificial pollination at all. Then the west gourd ovary can not produce auxin, resulting in the hindrance of embryo growth in the melon. And the vegetative growth of the plant will also seize the growth nutrition of the melon. When the growth of female flowers is not nutritious enough. The content of plant auxin in the ovary will be significantly reduced, resulting in zucchini can not stone and appear melon phenomenon.

The above is a brief introduction to what is the reason for the gourd. That's all for today's introduction. This article is for reference only. I hope it can help you all.
