Melon sweetness improved
Increase the temperature difference between day and night According to the biological characteristics of melon, enter the melon fruit expansion period, the daytime temperature in the shed is controlled at about 35°C, the night temperature is controlled at 18°C~20°C, and the temperature difference around 10°C is good for photosynthetic products (sugar Accumulation of class).
With the increase of potassium fertilizer, the low potassium content of soil nitrogen resulted in low sweetness and reduced quality of melon. Nitrogen fertilizers have high contents and the plant nutrition grows too profusely; the low potassium content will hinder the accumulation of photosynthetic organic products to fruits. Therefore, controlling nitrogen fertilizer and increasing potassium fertilizer are effective measures to improve the sweetness of muskmelon. Each kilogram of potassium sulphate compound fertilizer 10 kg or spraying 0.3% potassium dihydrogen phosphate 500 times and 3% of white sugar solution, the effect is better.
Moderate harvesting General autumn pods Thick muskmelons develop fully mature after 30 to 35 days, the sugar content is high, the flavor is good. However, at present, some melon farmers often harvest early for the morning market, seriously affecting the sweetness of muskmelon. Therefore, proper harvesting is the most basic measure to ensure the sweetness of muskmelon.
In addition, controlling the watering about 7 days before harvest can also increase the sweetness of the melon.
