In the seedling stage of watermelon, fertilizer is essential for the growth of the plant. Choosing the right fertilizer can not only promote the rapid growth of watermelon seedlings, but also improve their disease resistance and yield. So, what fertilizer do watermelon seedlings use to grow fast? This article will introduce it to you in detail. Watermelon planting
1. Nutritional requirements of watermelon seedlings.
First of all, we need to understand the nutrients needed for watermelon seedlings. Nitrogen, phosphorus, and potassium are the main elements needed for plant growth, and they are especially important in the seedling stage of watermelon. Appropriate amount of nitrogen fertilizer can promote leaf growth and improve photosynthesis efficiency. Phosphate fertilizer helps in root development and flower bud differentiation; Potash fertilizers help to increase the plant's resistance to stress.
2. Which fertilizers are suitable for watermelon seedlings?
1.Organic fertilizer: Organic fertilizer is rich in a variety of nutrients, including nitrogen, phosphorus, potassium and trace elements, which can fully meet the nutritional needs of watermelon seedlings. At the same time, microorganisms and beneficial bacteria in organic fertilizers can improve soil structure and improve soil fertility.
2.Compound fertilizer: a special compound fertilizer for watermelon seedlings, which is formulated according to a scientific formula, can meet the needs of major elements such as nitrogen, phosphorus and potassium at the seedling stage of watermelon. These fertilizers usually contain moderate amounts of trace elements that help improve disease resistance and yield in watermelons.
3.Water-soluble fertilizer: Water-soluble fertilizer is a fast-acting fertilizer that is suitable for watermelon seedlings. It can be quickly absorbed by plants and promote the growth of watermelon seedlings. However, when using water-soluble fertilizers, attention should be paid to the concentration and the number of fertilization applications to avoid the phenomenon of seedling burning.
3. Fertilization recommendations.
1.Fertilizer amount: At the watermelon seedling stage, it is recommended to apply 1-2 tons of organic fertilizer or 20-30 kg of compound fertilizer per mu. The amount of fertilizer can be adjusted appropriately according to soil fertility and seedling condition.
2.Fertilization method: When fertilizing, the fertilizer should be evenly sprinkled in the melon field to avoid concentrating in a certain area and causing seedlings to be burned. After fertilization, it should be watered in time to promote nutrient absorption.
3.Top dressing: According to the growth of watermelon seedlings, an appropriate amount of water-soluble fertilizer can be applied at the early stage of growth to promote the rapid growth of plants. However, it is necessary to pay attention to controlling the concentration and the frequency of fertilization.
4. Precautions.
1.Avoid excessive fertilization: Excessive fertilization may lead to seedling burning and affect the growth of watermelons. Therefore, the principle of appropriate amount should be followed when fertilizing.
2.Choose the right fertilizer: There are differences in the quality of different brands of fertilizers, and choosing a high-quality fertilizer is an important factor to ensure the growth of watermelon. Try to choose reputable brands and dealers to buy fertilizers.
3.Pay attention to the timing of fertilization: Fertilization should be carried out on sunny days to avoid nutrient loss caused by fertilization in rainy days. At the same time, it should be watered in time after fertilization to promote nutrient absorption.
4.Observe the growth situation: After fertilization, the growth of watermelon should be closely observed, and if there is an abnormality, measures should be taken to adjust the fertilization plan in time.
Through proper fertilization, we can promote the rapid growth of watermelon at the seedling stage, improve its disease resistance and yield. In actual production, the fertilization scheme should be flexibly adjusted according to the specific situation to ensure the healthy growth of watermelon. At the same time, strengthening field management, regular weeding, soil loosening and pest control are also important measures to achieve high yield and high quality.
