The Latest Methods to Make Melons Sweeter, Effectively Increasing Fruit Sweetness

Since melon is named melon (sweet melon), its taste is certainly sweet, but many farmers report that the melons they grow have low sweetness and even a bit of bitterness. The sweetness of melons is closely related to their sugar content; the sugar content determines the sweetness of the melon, and some have less sugar content for certain reasons, so they are not sweet. So how can the sweetness of melons be improved? Let's take a look together.

1. Reasonable Fertilization

Reasonable fertilization can improve the quality of melons and increase sugar content. Before planting, sufficient base fertilizer should be applied; 2000-3000 kg of decomposed farmyard manure per mu can be applied, together with 150-200 kg of potassium sulfate compound fertilizer. When the melon grows to the size of an egg, it should be topdressed in time; at this point, a swelling-melon fertilizer can be applied along with watering. Melon is a potassium-loving plant and has a relatively large demand for potassium in the later stage; applying more potassium fertilizer can improve the variety and yield of melons. In addition, when the plant shows deficiency symptoms, its growth nodes are hindered, and both yield and quality decline, so spraying micro-fertilizer is needed to solve this. After fruit set, a low-concentration mixed solution of calcium chloride and boric acid can be sprayed on the leaves, once a week for 2-3 consecutive times, to supplement the nutrients the plant needs. In the later stage, spraying potassium dihydrogen phosphate foliar fertilizer significantly increases yield and improves quality.

2. Increase the Day-Night Temperature Difference

When the fruit is ripening, it needs sufficient light and a relatively large day-night temperature difference, which is beneficial to the accumulation of sugar in the fruit. During the fruiting period, reduce ventilation during the day to raise the room temperature; at 35 degrees, the sugar synthesis of the fruit is 1 times higher than at 10 degrees, while at night ventilation should be strengthened to lower the room temperature, thus artificially creating an environment with a day-night temperature difference. If the nighttime temperature is too high, leaf respiration is large, carbohydrate consumption is relatively large, and sugar content will be reduced, causing the melon to be not sweet.

3. Control Moisture

During the normal growth of melons, after the fruit enters the ripening stage, water and nitrogen should be properly controlled, because when the fruit ripens, if excessive nitrogen is absorbed, unstable intermediate products such as nitrate will accumulate in the plant, causing excessive vegetative growth and easily triggering diseases. The same is true for water; when sugar is accumulating, watering too much will cause the fruit to expand rapidly and dilute the sugar, making the melon not sweet.

4. Harvest at Proper Ripeness

The quality of melons is closely related to the ripeness of the fruit. If picked when the fruit is not fully ripe, the sugar in the fruit has not yet fully converted, resulting in too low sweetness and insufficient aroma. If harvested too late, the stored substances in the fruit are exhausted, it becomes overly mature, and the cell tissues soften, resulting in an inferior taste.
