At the turn of warm spring and summer, watermelon is loved by people as a good product to cool off. If you want watermelon to be sweet, large, and juicy, the management of the seedling stage is crucial. So, what fertilizer can watermelon seedlings use to grow fast?
First of all, it is necessary to make it clear that the key to the rapid growth of watermelon seedlings lies in reasonable fertilization. Fertilizers not only provide the necessary nutrients for plants, but also improve the soil environment and create favorable conditions for watermelon seedlings to thrive. When choosing fertilizers, priority should be given to organic fertilizers. Organic fertilizer can not only provide comprehensive nutrition, but also improve soil structure, increase soil water retention and air permeability, and provide a good soil environment for the growth of watermelon seedlings.
In addition to organic fertilizers, compound fertilizers are also a good choice. Compound fertilizer contains a variety of nutrients such as nitrogen, phosphorus, potassium, etc., which can meet the needs of watermelon seedlings at different growth stages. Especially in the rapid growth period of watermelon seedlings, compound fertilizer can quickly provide the required nutrients and promote plant growth.
In addition, trace element fertilizers should not be ignored. Although watermelon does not require much trace elements, these elements have an important impact on the growth and quality of watermelon. For example, zinc improves the stress resistance of watermelons, while boron helps pollen germination and pollination.
In practice, it is recommended to combine basal fertilizer and top dressing. The basal fertilizer is mainly organic fertilizer, which can be mixed with the soil before planting. Top dressing should be supplemented with compound fertilizer and trace element fertilizer in a timely manner according to the growth of watermelon seedlings.
It's important to note that more fertilizer is not always better. Excessive fertilizer not only causes waste, but can also cause harm to watermelon seedlings. Therefore, the principle of "small amount and many times" should be followed when fertilizing, and reasonable adjustments should be made according to the growth of watermelon seedlings and soil fertility.
In short, choosing the right fertilizer and fertilizing it scientifically is the key to promoting the rapid growth of watermelon seedlings. Through reasonable fertilization, we can not only create conditions for high yield and high quality of watermelon, but also bring a sweet enjoyment to the hot summer.
