What if the latest melon is not sweet?

Summer is the season of cantaloupe on the market, cantaloupe has a faint sweet taste, but many friends find that many cantaloupes are not good in color, light in taste, not sweet at all, or even a little bitter. In fact, this is also the worry of many fruit growers, so what is this all about? The following pro-agricultural network brings you the reasons why the color of muskmelon is not good.

1. Variety

The sugar content of cantaloupe is related to its variety, and the sweetness of different varieties is different, so try to choose the variety with higher sweetness when planting.

2. Small temperature difference between day and night

We all know that many fruits in Xinjiang are world-famous, and many of them are very sweet, such as grapes and cantaloupe. In fact, this is largely due to the large temperature difference between day and night in Xinjiang, which is conducive to the accumulation of fruit sugar.

The greenhouse planting method can be used to reduce ventilation during the day to increase the room temperature of the greenhouse, which is conducive to the synthesis of sucrose, while at night to strengthen ventilation, reduce room temperature, and artificially create an environment with large temperature difference between day and night.

3. Improper management of fertilizer and water.

During the growth of muskmelon, nitrogen fertilizer can promote the rapid growth of plants, so more nitrogen fertilizer is applied in the growing period, but a large amount of nitrogen fertilizer has a great effect on sugar content. Excessive absorption of nitrogen fertilizer and accumulation of nitrate components make plants prone to long-term disease, especially in the fruit ripening period, when we should pay more attention to the control of nitrogen fertilizer and water.

In fertilization, we should pay attention to reasonable collocation, can not be partial to one of them, the lack of calcium in the soil is easy to form fermented melon, resulting in unsweet fruit, so try to apply organic fertilizer with nitrogen, phosphorus and potassium fertilizer, it is best not to water and fertilize in the first half of the harvest.

4. Unsuitable harvesting

The sweetness of cantaloupe is also related to ripeness. if the fruit is not fully harvested, the sugar has not been fully transformed, so the sugar is less and not sweet, but if it is harvested too late, its cell tissue will gradually become soft or old, resulting in poor taste. Also affect the taste.

Harvest must be timely, not too early and too late. According to research, sugar gradually accumulates during the development of cantaloupe, but the sugar accumulated during maturity accounts for 70% of the total.

The above is the pro-agricultural network for you how to do the melon is not sweet, know the reason why the melon is not sweet, how to prescribe the right medicine, hope to help you, more agricultural knowledge, please pay attention to the pro-agricultural network.
