When growing watermelons, suitable organic fertilizers include decomposed farmyard manure, commercial organic fertilizer, biological fertilizer and compound fertilizer. These fertilizers can provide the nutrients needed for watermelon growth, improve the soil environment, and help improve the yield and quality of watermelons.
(1) The importance of organic fertilizers to watermelon cultivation
In the process of watermelon cultivation, choosing the right fertilizer is crucial to improving yield and quality. Organic fertilizers contain rich organic matter and trace elements, which can continuously provide nutrients for watermelons, while improving soil structure and increasing soil fertility. Compared with chemical fertilizers, organic fertilizers have the advantages of environmental protection, safety and sustainability, and are an inevitable trend in the development of modern agriculture.
(2) Types of organic fertilizers suitable for watermelon cultivation
a. Decomposed farmyard manure
Decomposed farmyard manure is a common organic fertilizer, which is mainly made from fermented and decomposed animal and plant residues and excrement. It contains rich organic matter and trace elements, which can provide comprehensive nutrients for watermelons. At the same time, decomposed farmyard manure can also improve soil structure and increase soil water and fertilizer retention capacity. When using it, you should pay attention to the degree of maturity of farmyard manure to avoid using unripe farmyard manure to harm watermelon.
b. Commercial organic fertilizer
Commercial organic fertilizer is an organic fertilizer produced and processed in a factory, with the advantages of high nutrient content and stable quality. It can meet the various nutrient requirements of watermelon during growth and improve the yield and quality of watermelon. Compared with mature farmyard manure, commercial organic fertilizer is more convenient and quicker, and is suitable for large-scale growers.
c. Biofertilizer
Biological fertilizer is a fertilizer containing a large number of beneficial microorganisms, which can improve the soil microbial environment and improve soil fertility. Using biological fertilizer in the process of watermelon planting can increase the number of beneficial microorganisms in the soil, inhibit the growth of pathogens, and thus reduce the occurrence of diseases and pests. At the same time, biological fertilizer can also promote the growth of watermelon roots and improve the stress resistance of watermelon.
d. Compound fertilizer
Compound fertilizer is a fertilizer containing multiple nutrients, usually including nitrogen, phosphorus, potassium, etc. In the process of watermelon planting, you can choose the appropriate compound fertilizer for application according to the growth stage and nutrient requirements of watermelon. Compound fertilizer can quickly provide nutrients for watermelon and meet the needs of watermelon growth. However, it should be noted that the amount of compound fertilizer used should be properly controlled to avoid excessive use causing fertilizer damage.
Organic fertilizer, like a gift from nature, contains various trace elements and organic matter required for crop growth, and can provide a comprehensive and balanced nutritional environment for the watermelon root system. This not only promotes the vigorous growth of watermelon, but also gives the fruit a natural sweetness and juiciness. Decomposed farmyard manure, such as cow dung and sheep dung, is particularly favored by melon farmers because of its long-lasting fertilizer effect and mild nature. They can not only slowly release nutrients for continuous absorption by watermelon throughout the growth period, but also effectively improve the soil aggregate structure and enhance the soil’s ability to retain water and fertilizer.
In addition, the appropriate amount of compound fertilizer is also the key to high yield and high quality of watermelon. The scientific ratio of nitrogen, phosphorus, potassium and other macroelements in compound fertilizer can quickly meet the needs of watermelon at different growth stages, especially in the melon swelling period. Adequate potassium fertilizer supply plays an important role in improving watermelon quality and increasing yield. However, it should be noted that the application of compound fertilizer should follow the principle of “small amounts and multiple times” to avoid excessive application at one time, which may cause soil salinization or root burn.
In summary, the best choice for watermelon fertilization should be an organic combination of organic fertilizer and compound fertilizer, which not only meets the comprehensive nutritional needs of watermelon growth, but also takes into account the balance and health of soil ecology, so that every watermelon can bloom the sweetest smile on fertile land.
