The simple steps of drawing a watermelon field are as follows:

1. Draw a rectangular field as the background of the watermelon field. In the center of this field, draw a slightly flatter circle for the watermelon. Draw some curved lines around the watermelon as melon vines. These melon vines should spread out in all directions to show the vitality and vitality of the watermelon patch. At the bottom of the field, draw some short lines for the edges and soil of the watermelon patch.

2. We can add some details to improve this scene. On either side of the field, draw some small trees or shrubs to mark the boundaries of the watermelon patch. On the surface of the watermelon, draw some small lines and circles as the texture and details of the watermelon. These details can add richness and three-dimensionality to the picture.

3. In order to make the picture more vivid and interesting, we can add some characters or animals to the picture. For example, draw a farmer uncle working in the watermelon field, or draw some birds or butterflies flying over the watermelon field. These characters or animals can add vitality and interest to the picture.

4. We can use colored pens or paints to color the picture. Often, the background of a watermelon field can be painted with green paint to highlight its vitality and vitality. The watermelon can be painted with red paint to add dimension and detail.

Environmental characteristics of watermelon fields:

1. Soil: Watermelon fields usually require fertile, soft and well-drained soil. This soil is good for the growth and development of watermelons. Soil that is too heavy may hinder watermelon growth, while soil that is too sandy may lack necessary nutrients.

2. Water: Watermelon needs a lot of water, so the watermelon field should have good irrigation conditions. In dry areas, regular watering is needed to keep the soil moist. Excess moisture can cause root rot, so drainage is also essential.

3. Light: Watermelon needs a lot of sunlight. Therefore, choosing a sunny location is the key to growing watermelons. Watermelon growth may be affected in shade or shady areas.

4. Temperature: The optimal temperature for watermelon growth is usually between 25-30 degrees Celsius. During hot summer months, watermelons can be damaged by excessive heat. In colder areas, watermelons may not grow or grow slowly.

5. Fertilizer: In order to obtain high yield and high-quality watermelons, an appropriate amount of fertilizer needs to be applied regularly. Fertilizer provides the nutrients watermelons need, such as nitrogen, phosphorus and potassium.
