The temperature difference between day and night, which has a large temperature difference between day and night, is conducive to the accumulation of photosynthetic products (sugars). In the melon fruiting period, the temperature difference between day and night should be as large as possible. In general, the daytime temperature in the shed is maintained at 30°C-35°C, the nighttime temperature is maintained at 13°C-14°C, and the temperature difference between day and night is maintained at 16°C-18°C. Less application of chemical fertilizers, reuse of organic fertilizers based on organic fertilizers, and no or less application of chemical fertilizers are another effective measure to improve the sweetness of muskmelon. General organic manure is mainly chicken manure and bean cake, and 15 m3 of chicken manure and 100-150 kg of bean cake can be applied per mu. As a result, the sweetness of melon would be significantly reduced under the condition of increasing potassium in soil with low K fertilizer. Therefore, the amount of nitrogen fertilizer and potash fertilizer should be reduced during the melon melon period. In the initial stage of melons, irrigation can be performed with 8 to 10 kg of potash per acre or 20 kg of high-potassium compound fertilizer. Before the maturity of muskmelon, the water content in the ripening stage of melon ripening will not only reduce the sweetness of muskmelon, but also cause “water rotten melonâ€. Especially in the 10 days before the ripening of melon, we must pay attention to water control. Keep enough light to clean the shed film. The leaves that are shaded by melon should be carefully removed to enhance the transparency between the plants. Appropriate harvest melon development can generally be 30 to 35 days to fully mature, high sugar content, flavor is good. However, at present, some melon farmers often harvest early for the morning market, which seriously reduces the sweetness of melons. Therefore, proper harvesting is the most basic measure to ensure the sweetness of muskmelon. Royal Jelly is also called Bee Milk. The fresh royal jelly is slightly ropy milk paste substance; it is the excretive mixture of nutrition gland and maxilla gland of the head of little worker bee. The worker bees use this to feed the 1-3 days` worker bee larva and drone larva, 1-5.5 days` queen bee larva and queen bee in the oviposition period. The royal jelly is the biologic product containing very complicated active elements which contains almost all the nutrition elements required by the growth of the human body.
