What about the deformity of watermelon?

Many melons will have abnormal results, and the same is true of watermelons. Watermelons are malformed due to poor growth for some reasons. There are many reasons for deformed melons, which will be introduced later. There are mainly three kinds of common malformations, which will be specially introduced below. The preventive measures for the occurrence of deformed fruit should be decided according to the cause. Let's get to know it now.

I. malformed symptoms and causes

1. Crooked melon

Often form a partial head performance, generally inflated, and the other side of the development did not keep up, will cause this phenomenon. There are two reasons for the formation of flowers, one is the formation of flowers when the low temperature leads to flower hypoplasia, it will involve fruit deformities. Second, poor fertilization, seeds grow on one side, no seed area will not expand and form deformities.

two。 Flat melon

Round fruit varieties are easy to occur, the fruit grows longitudinally in the early stage and horizontally in the later stage. If one period of growth encounters low temperature, it will grow slowly, while in the other period, the normal temperature will grow fast, so uneven development will form a flat deformity. And the pericarp will thicken and the pedicel will be sunken.

3. Cucurbit melon

The direct manifestation is that one section near the pedicel will be rudimentary and the other will be enlarged. It's shaped like a gourd. This kind of imagination is generally caused by the uneven supply of fertilizer and water, which is generally caused by the early drought and the lack of water and fertilizer. after the improvement, the early growth has been completed and can not be reversed. Will cause this shape deformity.

II. Prevention and control measures

Planting in the open field should be planted after the temperature rises steadily, so that the florescence will not encounter low temperature, or plastic film cultivation. In protected cultivation, no matter what the external temperature is, the internal temperature should be adjusted to the most suitable temperature for flowering. In addition, the outside should be less ventilated at low temperatures and ventilated on sunny days. Fruit period to maintain the temperature above 25 degrees, it is best to automatically adjust, requiring that the night temperature can not be lower than 23 degrees so that there will not be low temperature, affecting the growth rate. There will be no deformed fruit. It is necessary to maintain fertilizer and water supply throughout the growth cycle, apply more nitrogen fertilizer in the early stage of plant growth, maintain plant growth potential, and ensure a humidity of about 60% in watering, and then re-apply fertilizer and water in the flowering and fruiting period, fertilizing once a month and watering once a week.

Watermelon deformities will mainly form crooked melon, flat melon, gourd melon three kinds of malformed symptoms, the main cause of deformity is that low temperature affects flower development, or low temperature affects fruit growth rate. In addition, the lack of nutrition and moisture causes deformities. If we take precautions against the causes during the flowering and fruiting period, we can basically avoid the problem of watermelon deformities.
