This article provides a detailed introduction to the growth cycle of watermelons and the correct fertilization methods, offering some gardening tips. Next, the site editor will introduce the information to netizens.
Watermelons are a very popular fruit, not only sweet in taste but also high in nutritional value. However, to grow high-quality watermelons, it is necessary to understand their growth cycle and the correct fertilization methods. This article will provide a detailed introduction to the growth cycle and fertilization techniques of watermelons.
I. The Growth Cycle of Watermelons
The growth cycle of watermelons generally consists of the following stages:
Seed Germination Stage: From sowing to seedling emergence, it usually takes 7-10 days. During this stage, the soil should be kept moist to help seeds absorb water, expand, and promote germination.
Seedling Stage: From seedling emergence to transplantation, it usually takes 20-30 days. During this stage, adequate lighting and suitable temperatures are needed to promote seedling growth.
Flowering Stage: From transplantation to flowering, it usually takes 30-40 days. During this stage, adequate lighting and suitable temperatures are needed to promote bud differentiation and flowering.
Fruiting Stage: From flowering to fruit maturity, it usually takes 30-50 days. During this stage, adequate lighting, suitable temperatures, and sufficient water are needed to promote fruit expansion and ripening.
Harvesting Stage: From fruit maturity to harvesting, it usually takes 7-10 days. During this stage, timely harvesting is necessary to ensure fruit quality and taste.
Overall, the growth cycle of watermelons is generally 90-120 days, but the specific number of days can be influenced by factors such as variety, climate, and soil.
II. Correct Fertilization Methods
Base Fertilization: Before planting watermelons, sufficient base fertilizer needs to be applied. Base fertilizer is usually organic, such as compost or green manure, and is combined with an appropriate amount of chemical fertilizers, such as nitrogen, phosphorus, and potassium fertilizers. The application rate of base fertilizer is generally 3000-5000 kilograms per mu.
Top Dressing: During the growth of watermelons, timely top dressing is required. Top dressing is generally divided into the following stages:
- Seedling Stage: During the seedling stage, a small amount of nitrogen fertilizer can be applied to promote seedling growth. Generally, 5-10 kilograms of urea is applied per mu.
- Flowering Stage: During the flowering stage, a small amount of phosphorus and potassium fertilizers can be applied to promote bud differentiation and flowering. Generally, 5-10 kilograms of superphosphate and 5-10 kilograms of potassium sulfate are applied per mu.
- Fruiting Stage: During the fruiting stage, the amount of fertilization needs to be increased to promote fruit expansion and ripening. Generally, 10-15 kilograms of urea, 10-15 kilograms of superphosphate, and 10-15 kilograms of potassium sulfate are applied per mu.
Foliar Fertilization: During the growth of watermelons, foliar fertilization can be carried out to supplement the nutrients required by the plant. Foliar fertilization usually consists of nitrogen, phosphorus, and potassium fertilizers, and can also add trace elements such as boron, zinc, and iron. The concentration of foliar fertilization is generally 0.1%-0.3%, with喷施 (spraying) every 7-10 days.
Fertilization Precautions:
- Fertilization should be uniform, avoiding local excess or insufficiency.
- Fertilization should be timely, avoiding application under adverse conditions such as high temperatures or drought.
- Fertilization should be moderate, avoiding excessive fertilization that can lead to excessive plant growth, affecting fruit quality and yield.
- Fertilization should be adjusted based on soil and climate conditions, in line with soil fertility and climate characteristics.
In summary, correct fertilization methods are crucial for the growth and yield of watermelons. Only with rational fertilization can the quality and taste of watermelons be guaranteed, improving economic benefits.
III. Conclusion
The growth cycle and fertilization methods of watermelons are very important for growers. Understanding the growth cycle of watermelons can help growers arrange planting time and management measures reasonably; mastering the correct fertilization methods can ensure the nutritional needs of watermelons, improving fruit quality and yield. We hope this article is helpful to many growers, wishing everyone to grow high-quality watermelons and reap substantial returns.
