What kind of fertilizer makes watermelons big and sweet?

To achieve high yields in西瓜 cultivation, the control of temperature is the first step. Watermelons are warm-loving crops and have high requirements for temperature. During planting, if the temperature is lower than 15℃， it will affect the growth and development of the root system, causing slow recovery from transplanting and even plant death； if the temperature is too high， it may result in scorching or burning of the plants. 
What kind of fertilizer makes watermelons big and sweet? When planting watermelons, it is necessary to ensure that the soil temperature is above 15℃. In northern regions, it is recommended to apply root-promoting agent and micro-biotic agent when irrigating the soil, which can increase the soil temperature, help the watermelon seedlings quickly take root, adapt to the growth environment, prevent the occurrence of dead plants and rotten seedlings, and improve the survival rate and promote the growth of healthy seedlings.

What kind of fertilizer makes watermelons big and sweet? During the fruit-setting period, appropriately regulating the temperature difference between day and night is beneficial for fruit setting. At this time, fertilizing the roots is very crucial. Good fertilization leads to a higher fruit setting rate, faster enlargement, and ensures the quality and flavor of the fruits. I suggest that you should not seek cheap options. Instead, choose more effective special water-soluble fertilizers, such as balanced powder fertilizer + calcium-magnesium granular fertilizer. This not only meets the nutritional needs of the watermelons, but also provides comprehensive supplementation of major and trace elements, and can also improve the soil, promote root growth, and enhance the soil's water and nutrient retention capacity. 
What kind of fertilizer makes watermelons big and sweet? During the middle growth stage of watermelots, if there is drought or nutrient deficiency, the plants will exhibit symptoms such as shorter stem nodes, thinner vine, and slow growth. We can, based on the growth condition of the watermelon seedlings, appropriately add root-promoting agents and micro-biological agents to nourish and protect the roots, preventing the early decline of the plants that may cause difficulties in watermelon enlargement. Additionally, combined with balanced powder fertilizer and calcium-magnesium granular fertilizer, apply them once every 10-15 days to replenish nutrients and prevent watermelon cracking and abnormal fruit shapes.

What kind of fertilizer makes watermelons big and sweet? During the period when watermelons are growing larger and becoming sweeter, it is necessary to control the water intake properly to prevent the watermelons from bursting. Pay attention to turning the watermelons to avoid uneven exposure to sunlight, which may affect the sweetness of the watermelons. Fertilization should mainly focus on potassium, using potassium-rich powder water-soluble fertilizer combined with microbial agents, which can increase the sugar content of the watermelons. 
To manage a watermelon crop properly, one must pay attention to factors such as temperature, light, water and humidity. What's more crucial is to use the right type of fertilizer. Otherwise, there will be many diseases, many deformed fruits, and the plant may prematurely wither or have difficulty in swelling, which will affect the yield.
