The causes and Preventive measures of the latest Cucurbita sativa

Zucchini in the planting of common melon phenomenon, the so-called melon refers to the fruit in the expansion of the midway stop, and began to yellow, withered Yan, and finally become a withered melon, this phenomenon occurs before and after flowering. So what causes zucchini melons? How to prevent? Let's take a look at the pro-farming network together.

1. Variety

There is a pair of physiological differences among different varieties of summer squash. Different varieties planted in different areas have different mellowing rates. According to experiments, the varieties with more endogenous hormones produced in seedling stage have less mellowing rate.

Preventive measures: In the selection of planting, select some excellent varieties with strong resistance and certain parthenocarpy ability, which is one of the main means to prevent melons from appearing.

2. Temperature

Temperature is also one of the main reasons for the appearance of melons in zucchini. If the temperature is too high, the photosynthesis of planting will be affected to a certain extent, and the respiration will be strengthened, resulting in accelerated nutrition and growth, resulting in excessive growth of plants, resulting in malnutrition of fruits and melons. Similarly, if the temperature is low, it will also affect photosynthesis, resulting in weak root absorption, poor plant growth, lack of nutrition, resulting in melons.

Preventive measures: The most suitable temperature for zucchini during flowering is between 22-25 degrees, maintained within 30 degrees during the day, more than 30 degrees will appear above, and the night needs to be maintained at 15-20 degrees, and the temperature is lower than 15 degrees. When planting in greenhouses, more than 30 degrees, ventilation can be strengthened to reduce the temperature in the shed, and at low temperatures, boron film will be covered and compacted to prevent temperature emission.

3. Light

Light causes melons to melt for the same reason as temperature. In rainy seasons, plants do not receive sufficient light, resulting in weakened photosynthesis, so they cannot synthesize and accumulate nutrients, resulting in malnutrition.

Preventive measures: In rainy weather with insufficient light, artificial light supplement method can be improved to enhance photosynthesis, or strengthen fertilizer and water management, so that plants have sufficient nutrients for growth and development.

4. Toxic gases

Toxic gases are also one of the reasons for melons, mainly in the case of greenhouse planting, in the greenhouse planting, fertilizers and drugs will release some toxic gases under decomposition, coupled with the general ventilation environment in the greenhouse, some of these gases will slowly accumulate, when reaching a certain amount will harm plant growth. For example, too high or too high carbon dioxide in the air will cause photosynthesis, nutrient synthesis will be hindered, resulting in poor flower development, resulting in melons, and sulfur dioxide will produce sulfurous acid after encountering moisture, which will also affect photosynthesis and cause the same effect.

Preventive measures: In view of this situation, it is necessary to strengthen ventilation, not only to adjust the temperature and humidity in the greenhouse, but also to adjust these gases.

5. Poor pollination

The main reason for summer squash melons is poor pollination or failure to pollinate due to various reasons, resulting in abnormal growth and development of embryos and endosperm. In addition, insufficient supply of nutrients makes fruits unable to grow normally, resulting in melons.

Preventive measures: poor pollination should be artificial auxiliary pollination, so that it can be normal results, artificial pollination time is best chosen in the morning of sunny weather, stamens will be cut off, collect pollen, and then pollen can be smeared on female flowers.

The above are the reasons and preventive measures for the zucchini melons brought by the pro-agricultural network. I hope to help you. If you want to know more about zucchini planting knowledge, please pay attention to the pro-agricultural network.
