How to Transplant Watermelons
A small piece of experience knowledge, introducing how to transplant watermelons and related knowledge about watermelon transplantation methods, which can certainly bring you help. Let's learn about it together!
Watermelon is a common fruit in our lives, and it also has an elegant name called "Green Door Green Jade Room," referring to the green and white skin of watermelons, which is very unique and beautiful. Watermelon is juicy and sweet, and eating a slice of cool watermelon in the hot summer has a cooling and heat-relieving effect. It is also known as the "King of Summer." Watermelon is rich in various nutrients beneficial to the human body. Eating more watermelon can beautify the skin and reduce internal heat. So, how should watermelons be transplanted during the planting process? Let's take a look together below.
One, Preparing for Transplantation
1. Land Preparation and Fertilization
Before transplanting, land preparation and applying base fertilizer should be done first. The land should be deeply cultivated and tilled, with a plowing depth of about 30cm. After plowing, level the land and create ridges, with ridge heights of 15~20cm and widths of 1.2~1.3m. Land preparation should be combined with fertilization. Decomposed compound fertilizer should be used as the base fertilizer, and farm manure can be used, along with some potassium fertilizer and urea as auxiliary fertilizers. One week before transplanting, cover the ridges with plastic film to keep them warm.
2. Seed Treatment
Pay attention to selecting healthy and plump high-yield seeds. After selecting the seeds, place them in the sun to dry for 3 days to disinfect them, with 3 hours of sun exposure each day. Then, soak the seeds in warm water for about 5~7 hours, and then place them in a sodium tripolyphosphate solution for half an hour. After the seeds are treated, you can use the fire炕 method to germinate the seeds. When the seeds have germinated sufficiently, you can proceed with the transplantation.
Two, Transplanting Process
1. Transplanting Time
Transplanting can be done when the watermelon seedlings have two true leaves and one heart or three true leaves and one heart, usually around the time of Qingming Festival, when the ground temperature stabilizes at around 15°C. Note that transplanting should be done on sunny days.
2. Transplanting Density
The spacing between plants should be (2.5~3)m × (0.8~1)m. Generally, three rows can be planted on one ridge, with 220~250 seedlings per 667㎡ of land.
3. Transplanting Method
According to the transplanting density, use a planting machine to dig planting holes in the middle of the ridge. The planting holes should be 5cm deep and 4cm in diameter. Then, carefully place the seedlings in the holes and cover them with backfill soil. If no base fertilizer has been applied, fertilizer can be added while planting, such as applying 150g of sulfate potassium ternary compound fertilizer and 100g of potassium dihydrogen phosphate per 667㎡. After transplanting, water the seedlings to help them adapt, but be careful not to use too much water.
Three, Post-Transplanting Management
1. Seedling Adaptation Period Management
Three days after transplanting, check the seedlings. If there are any dead seedlings, replace them with new ones. If there are wilted or weak seedlings, you can apply 0.3% potassium dihydrogen phosphate and 0.4% urea solution 500ml in the afternoon on a sunny day to promote their healthy growth. Also, during the adaptation period after transplanting, pay attention to keeping the seedlings warm, as there is also abundant rainfall, so water control should be done.
2. Seedling Clump Period Management
When watermelon seedlings have grown 5 true leaves and start to sprawl, it indicates that they have entered the clump stage, which usually lasts for about half a month. During this period, ensure that the seedlings have a good ventilation and lighting environment, and adjust temperature and humidity appropriately. It is also necessary to slightly inhibit the growth of watermelons to make them more resistant to stress.
3. Fruit Setting Stage Management
After the clump stage, watermelons enter the fruit-setting stage. At this time, the temperature rises, and it is important to manage the watermelons carefully to prevent excessive stem and leaf growth and improve fruit-setting rate. Strengthen ventilation, cover the watermelons with a thin layer of plastic film at night, and make sure to supply them with adequate nutrients.
