How to Plant Watermelon Outdoors
Here we will explore the knowledge of planting watermelons outdoors and the detailed cultivation techniques of watermelon, a type of green plant and flower. Let's learn about it together.
Watermelons, also known as summer melon, winter melon, and green jade house of Qingmen, are distributed in temperate and tropical regions. They belong to the Cucurbitaceae family, Citrullus lanatus, and are annual vines. When planting watermelons outdoors, if seed planting is used, the seeds need to be treated first, then seedlings are grown in a nursery and later transplanted to the planting field. If purchasing seedlings directly, you can plant them after tilling the soil. Let's understand the planting methods together.
1. Seed Treatment
If planting with seeds purchased from the market, the seeds need to be treated. Select full and shiny seeds, expose them to the sun for 2 days, then soak them in 55℃ warm water for 2 hours, followed by soaking in a fungicide solution for 5 minutes. After that, plant them in the nursery, and once the seeds grow into seedlings, transplant them to the planting field.
2. Tilling the Soil
Before planting seedlings, the soil needs to be tilled to make it loose, which is beneficial for improving drainage and aeration. The depth of tilling should be about 20 centimeters. After tilling, let the soil be exposed to the sun for 10 days before planting to kill any eggs that might be present. Ten days before planting, fertilize the soil with 150 pounds of nitrogen-potassium compound fertilizer per mu.
3. Planting
When the soil surface temperature is stable at 15℃, you can plant the watermelon seedlings. You can refer to a planting density of 600 to 800 seedlings per mu. Plant the seedlings 3 centimeters deep into the soil, firm the roots with fine soil, water thoroughly once, and no need to water within a week. Then, based on the soil moisture condition, water the second time after 10 days.
4. Seedling Management
Do not water the seedlings frequently during the growing period. Water only when the soil is dry, maintaining slight moisture. Always be cautious of cold air to prevent the seedlings from being frostbitten when the temperature is below 10℃. During the growing period, the seedlings require a lot of fertilizer. You can pile a layer of withered leaves on the soil surface and spray 500 grams of glucose and 40 pounds of penicillin per mu.
5. Pest and Disease Prevention
During the seedling growth period, it is necessary to spray specialized agents at intervals for pest and disease prevention. When powdery mildew occurs, spray with diluted tebuconazole or difenoconazole. When pests appear, apply hymexazole solution for root irrigation or spraying.
