What Fertilizer to Use for Watermelons
Introduction to the article: Knowledge about the use of fertilizers for peppers and pepper fertilization methods, next [] the editor will introduce.
When growing watermelons, it is important to apply sufficient base fertilizer. If the soil fertility is low, more fertilizer should be applied. In more fertile areas, less fertilizer is needed. After germination and growth, fertilizers should be applied according to the growth status. When the seedlings have 3-4 true leaves, top-dressing should be done. Top-dressing should be applied again during the vine stretching stage, after flowering during the fruit expansion stage, and nutrients should be supplemented appropriately in the later growth stage according to the growth status of the watermelon.
Pepper Fertilization
The fertilization of watermelons is mainly divided into two categories: base fertilizer and top-dressing. The base fertilizer mainly meets the needs of the early growth of the seedlings, promoting vine growth, flower bud differentiation, seedling thickening, and seedling strengthening. Top-dressing can be divided into root top-dressing and foliar top-dressing, with root top-dressing as the主导 and foliar top-dressing as a supplement.
1. Seedling Stage
The seedling stage refers to the period from the transplantation of watermelon seedlings to the growth of 5-7 leaves. During this period, top-dressing can promote root development and accelerate the growth of the above-ground part. However, the amount of top-dressing should not be excessive, especially nitrogen fertilizer should be moderate to avoid excessive growth of seedlings.
2. Vine Stretching Stage
When watermelons enter the vine stretching stage, it starts from when the watermelon has grown 5-6 leaves to the opening of the second female flower. During this period, top-dressing should combine promotion and control, aiming to promote rapid stem and leaf growth while preventing excessive fertilizer and water from causing vine elongation.
3. Fruiting Stage
Generally speaking, when the young watermelon fruit grows to the size of an egg, it can start to apply fruiting fertilizer, mainly composed of decomposed human manure, to promote the expansion of the young fruit and ensure the growth of the vines. When the young watermelon fruit grows to 15-20 centimeters in diameter, the second fruiting fertilizer should be applied. Top-dressing should be stopped 7-10 days before harvest to improve the quality of the watermelon fruit.
Pepper Fertilization Method
When growing watermelons, it is important to choose the right type and amount of base fertilizer to meet the growth needs of the seedlings. Watermelon seedlings grow very fast and have high nutrient requirements, including macronutrients such as nitrogen, phosphorus, and potassium, micronutrients such as calcium, boron, and zinc, and abundant organic matter. Therefore, when choosing base fertilizer, it is necessary to add various types of fertilizers such as compound fertilizers, organic fertilizers, and micronutrient fertilizers. If the base fertilizer is insufficient in nutrients, it will cause slow growth of the seedlings, inadequate nutrient accumulation, short growth period, weak growth, few flowering and fruiting, seriously affecting the yield and quality of watermelons and reducing production efficiency.
