Increasing the temperature difference between day and night to increase the temperature difference between day and night is beneficial 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.

Re-applying organic fertilizer, using less organic fertilizer as fertilizer, and not applying or reducing chemical fertilizer is an effective measure to improve the sweetness of muskmelon. General organic fertilizers mainly include biogas residue, straw rot, chicken manure and bean cake. Chicken feces 15 m3 and bean cake 100-150 kg can be cooked per mu. Rationally increase potash fertilizer. In the case of low potassium levels in the soil, the sweetness of melons will be significantly reduced. Therefore, the amount of nitrogen fertilizer and potassium fertilizer should be reduced in the melon melon period. It can be used in the early stage of melons with potassium per application of 8-10 kilograms of potassium fertilizer or 20 kilograms of high-potassium compound fertilizer. Fertilization should be combined with the use of plant e-fertilizers, utilizing the principle of high-energy electrons and plant electron polarity sensing produced by the photosynthesis of plants to increase the cell division, molecular synthesis, and nutrient-matched digestion levels, accelerate the metabolic frequency, and activate the plant nutrient-passing system to produce superior fertilizer effects. .

Proper control of water melon ripening soil moisture is too large, not only will reduce the sweetness of melon, but also prone to "water rotten melon." Especially in the 10 days before the ripening of melon, we must pay attention to water control.

Increase the light shed film to diligently wipe, do not have water droplets, leaves should be paid attention to thinning around the melon to increase the transparency between plants. Spraying new high-fat membranes can prevent virus infection in leaves and enhance the lush foliage, photosynthetic product accumulation, and directional transport capacity.

Reasonably harvested 30 to 35 days of melon development can be fully matured, with high sugar content and good taste. Therefore, proper harvesting is also the key to ensuring the sweetness of muskmelon.
