The reasons for the bad fruit setting of the latest watermelon

Watermelon is favored and loved by many people in our country, and the market demand is increasing, and the relative planting area is also getting wider and wider, but many novices have encountered the same problem in the planting process, that is, bad fruit setting will seriously affect the yield of watermelon and the income of farmers. So what is the reason that affects the bad fruit setting of watermelon? Why is the fruit of watermelon bad? Let's take a look at it.

1. Temperature

Watermelon is a bisexual flowering crop, which uses bees and other insects for pollination, but if it encounters overcast, rainy and low temperature during flowering, it will affect the pollination and fertilization of watermelon and make the fruit setting of watermelon bad. If it is open-air cultivation, Rain Water dripping on the style will make the pollen absorb water and break up, unable to pollinate. The high temperature environment will lead to the crazy growth of watermelon vines, affecting the nutrition and moisture of the fruit, resulting in poor fruit setting.

2. Lighting

Watermelon is a very watermelon fruit, which requires a lot of light intensity and time during the whole growing period from sowing to ripening. If the light is too weak, it will make the watermelon internodes long, the leaves large and thin, leading to strong photosynthesis, and finally because of lack of nutrition and fruit drop, the final sugar content of the fruit will be reduced, the quality is poor.

3. Moisture

The drought tolerance of watermelon is particularly strong, and the environment in which it grows needs relatively dry soil and air. If the relative temperature in the air is higher than 60%, the growth of watermelon will be fine, the fruit setting rate will decrease, and it is easy to produce diseases and insect pests. However, less than 50% will affect the growth of watermelons and do some harm to pollen germination, and the water holding capacity of the soil needs to be kept between 65% and 75%.

4. Density

Planting density should not be too dense, too thin, too dense will cause each watermelon can not evenly absorb nutrients, can not ensure that all watermelons can grow normally, and may even develop malformations. And the field permeability is too poor, seriously affecting the growth of underground leaves and stems, resulting in poor fruit setting. Excessive thinning will make watermelons overnourished, cause watermelons to grow into tillers and affect normal fruit development.

5. Nitrogen fertilizer

In order to increase the yield and quality of watermelon, many friends will use too much nitrogen fertilizer, but it will be counterproductive. Although nitrogen fertilizer promotes growth, excessive fertilization will lead to excessive growth of watermelon vines and leaf stems, imbalance between plant vegetative growth and reproductive growth, fruit malnutrition, poor fruit setting and even flower drop.

Well, the above are the main reasons for the bad fruit setting of watermelon. Of course, there are more than these, for example, there are diseases and insect pests, if there is no timely prevention of watermelon diseases and insect pests or treatment of diseases and melons, diseases and insect pests harm the growth of melons and fruits, and it will also cause poor fruit setting of watermelons. Therefore, I hope that everyone will pay more attention to minimize or put an end to this situation at ordinary times.
