Causes of poor color and sweetness of cantaloupes

What is the reason for the poor color and sweetness of cantaloupes? That is a misunderstanding of pruning and water and fertilizer management. The main reasons are as follows:

Causes of poor color and sweetness of cantaloupes

1. Improper selection of varieties
The sweetness of cantaloupe is related to its species, so it is necessary to select high-quality varieties when planting cantaloupe.

2. Overweight pruning
The proportion of mature leaves is too small, nutrient supply is insufficient from fruit ripening to sugar accumulation, plant premature senescence, leaf aging, weakening or losing the ability to produce nutrients, and the fruit epidermis is delicate and crisp in order to maintain its own development instead of leaf nutrient production, to mature peel. Surface chlorophyll synthesis is greater than decomposition, so that the pericarp cells contain a large amount of chlorophyll, can not turn yellow, so the color is not good, sweetness is also poor.

3. Too few leaves remained in the whole plant
Fruit was bare and most of the fruit surface was exposed to direct light, which could easily cause the fruit temperature to rise and inhibit the synthesis of yellow carotenoids. Direct light is beneficial to the synthesis of green chlorophyll. Scattered light is conducive to the synthesis of yellow carotenoids. Because the back shade fruit receives more scattered light, it first displays the Yellow carotenoids, so the fruit covered by leaves is well colored.

4. Improper application of water and fertilizer
In the later stage of fruit setting, that is, 10 days before the market, no special drought, no watering, watering will significantly reduce the sweetness of cantaloupes. Muskmelon growth should pay special attention to increasing potassium fertilizer, potassium fertilizer has a significant role in improving the quality of melon. To control nitrogen fertilizer, excessive application of nitrogen fertilizer will not only reduce melon sweetness, but also cause excessive accumulation of nitrite, which is harmful to human body. The principles of controlling nitrogen, applying phosphorus and increasing potassium should be mastered in the application of cantaloupe, so as to achieve the combined application of nitrogen, phosphorus and potassium.
