What is the reason that causes the color of the melon to be poor and not sweet? It is a misunderstanding of pruning and water and fertilizer management. The main reasons are as follows:
The reason why the color and sweetness of the melon is not sweet
1. Improper selection of species
The sweetness of muskmelon is related to the species nature. When planting muskmelon, we must choose high-quality varieties.
2. Overweight
The proportion of young leaves is too small, the fruit is mature until the sugar accumulation period, nutrient supply is insufficient, premature aging of plants, aging leaves, weaken or lose the ability to produce nutrients, the fruit skin crispy in order to maintain their own growth instead of the leaves to create nutrients, to mature peel. The surface chlorophyll synthesis is greater than the amount of decomposition, so that the skin cells contain a lot of chlorophyll, can not turn yellow, so the color is poor, sweetness is also poor.
3. Too few leaves reserved for whole plant
The fruit is basically bare, and most of the fruit surface is exposed to direct light, which can easily cause the temperature of the fruit to increase and inhibit the synthesis of yellow carotenoids. Direct light favors the synthesis of green chlorophyll. Scattered light contributes to the synthesis of yellow carotenoids. The shaded fruit receives more scattered light and first expresses the carotenoid yellow. Therefore, the fruit covered by the leaves is colored well.
4. Improper application of water and fertilizer
In the late stage of melons, 10 days before the listing, it is not particularly arid, do not water, watering will significantly reduce the sweetness of melon. The melon should pay special attention to the application of potassium fertilizer during the growth period, and the potassium fertilizer can obviously improve the quality of the melon. To control nitrogen fertilizer, excessive application of nitrogen fertilizer will not only reduce the sweetness of melon, but also make excessive accumulation of nitrite, which is harmful to the human body. The application of nitrogen, phosphorus, and potassium in the fertilization of melon should be controlled so that nitrogen can be achieved. , P, K combined application.
