How to Plant Watermelon Outdoors
Today's focus is on how to plant watermelon outdoors and related knowledge about the cultivation techniques of outdoor watermelons. Next, the editor will introduce to everyone.
Watermelon, also known as summer melon, winter melon, and green gate jade house, is distributed in temperate and tropical regions and is an annual vine plant of the Cucurbitaceae family. When planting watermelon outdoors, if seed planting is used, the seeds need to be treated, seedlings are cultivated in the seedling field, and then planted in the planting field. If seedlings are purchased directly, they can be planted after the soil is plowed. Let's understand the planting method together.
1. Seed Treatment
If seeds are purchased from the market for planting, they need to be treated. Select full and shiny seeds from the purchased seeds, expose them to the sun for 2 days, then soak them in warm water at 55℃ for 2 hours, followed by soaking in a carbendazim solution for 5 minutes. After that, plant them in the seedling field and wait for the seeds to grow into seedlings before transplanting them to the planting field.
2. Plowing the Soil
Before planting seedlings, the soil needs to be plowed to loosen it, which is beneficial for enhancing drainage and aeration. The depth of plowing should be about 20 centimeters. After plowing, let the soil be exposed to the sun for 10 days before planting to kill any eggs that may be present in the soil. 10 days before planting, fertilize the soil with 150 jin of nitrogen-potassium compound fertilizer per mu.
3. Planting
When the temperature of the soil surface is stable at 15℃, watermelon seedlings can be planted. Refer to a planting density of 600 to 800 seedlings per mu. Plant the seedlings 3 centimeters deep into the soil, press the roots firmly with fine soil, water thoroughly once, and no watering is needed within a week, until 10 days later, water the second time based on the dryness or moisture of the soil.
4. Seedling Management
Do not water the seedlings frequently during the growing period. Water only when the soil is relatively dry, keeping the soil slightly moist. Always be aware of preventing cold air to avoid frost damage to the seedlings 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 jin of penicillin per mu.
5. Preventing Diseases and Pests
During the seedling growing period, it is necessary to spray specialized agents at regular intervals to prevent diseases and pests. When powdery mildew occurs, spray diluted tebuconazole or difenoconazole. When pests occur, use hymexazole solution for root irrigation or spraying.
