Causes and Preventive measures of Cucurbita moschata

Zucchini is often seen in the cultivation of melon phenomenon, the so-called melon refers to the fruit in the middle of the expansion stopped, and began to yellowing, wilting, and finally into a dry shrunken melon, this phenomenon occurs both before and after flowering. So what is the reason for the watermelon? How to prevent it? Let's take a look at the pro-farm network.

1. Variety

There are a pair of physiological differences among the varieties of zucchini. If different varieties are planted in different areas, their melon rate is also different. According to the experiment, the more endogenous hormones are produced in the seedling stage, the less the melon rate is.

Preventive measures: when choosing to plant, choose some excellent varieties with strong resistance and certain parthenocarpy ability, which is one of the main means to prevent the emergence of melon phenomenon.

2. Temperature

Temperature is also one of the main reasons for the emergence of melons in zucchini. If the temperature is too high, it will affect the photosynthesis of planting to a certain extent, strengthen respiration, lead to faster nutrition and growth, and make plants grow excessively, resulting in malnutrition in the fruit and causing 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 melon.

Precautions: the most suitable temperature for zucchini to blossom and bear fruit is between 22 and 25 degrees, keep it within 30 degrees during the day, above 30 degrees, and keep it at 15-20 degrees at night, even if the temperature is lower than 15 degrees. When planting in the greenhouse, more than 30 degrees can enhance ventilation and reduce the temperature in the greenhouse, while at low temperature, the boron film will be covered and compacted to prevent temperature emission.

3. Lighting

The cause of light is the same as temperature. In overcast and rainy season, plants can not receive enough light, which leads to the weakening of photosynthesis, so the synthesis and accumulation of nutrients can not be reduced, and finally lead to malnutrition.

Preventive measures: in the overcast and rainy weather with insufficient light, it can improve the method of artificial light supplement, enhance photosynthesis, or strengthen fertilizer and water management, so that plants have sufficient nutrients for growth and development.

4. Toxic gases

Poisonous gas is also one of the causes of melons, mainly in the case of planting in the greenhouse, fertilizers and drugs will release some toxic gases under decomposition in the greenhouse, coupled with the general ventilation environment in the greenhouse, some of these gases will slowly accumulate and endanger plant growth when they reach a certain amount. For example, if the carbon dioxide in the air is too high or too high, it will cause photosynthesis, hinder nutritional synthesis, lead to flower dysplasia, cause melons, and sulfur dioxide will produce sulfite when it meets water. This substance will also affect photosynthesis and have the same effect.

Preventive measures: in view of this situation, it is necessary to strengthen ventilation, which can not only adjust the temperature and humidity in the greenhouse, but also play a good role in regulating these gases.

5. Poor pollination

The main reason for poor pollination of zucchini is poor pollination or inability to pollinate zucchini due to various reasons, resulting in abnormal growth and development of embryo and endosperm, coupled with insufficient supply of nutrients, so that the fruit can not grow normally.

Preventive measures: bad pollination should be assisted by artificial pollination, so that it can produce normal results. The best time for artificial pollination is to cut off the stamens on a sunny morning, collect pollen, and then smear the pollen on the female flowers.

The above are the causes and preventive measures of zucchini brought by the pro-agricultural network. I hope it can help you. If you want to know more about zucchini planting, please pay attention to the pro-agricultural network.
