Detailed Explanation of Key Points of Watermelon Sowing and Seedling Raising Techniques
Watermelon can be said to be a very popular fruit in our country. As temperatures gradually rise and summer approaches, watermelons also gradually enter their peak market season. Now is the best time for watermelon planting, and many farmers have gradually begun the work of sowing and raising watermelon seedlings. So how exactly should this be done? Below, the editor brings you the watermelon sowing and seedling raising techniques. Let's take a look!
1. Seedbed Selection
The seedbed is very important for seed germination. Before sowing, you must first choose a suitable planting plot as the watermelon seedling bed. The seedling bed should be chosen in a place that is sheltered from the wind, has sufficient sunlight, and has sufficient soil fertility. Then, according to the planting area, reasonably set up the trellis to facilitate the growth of watermelons. After choosing the land, simply improve the soil by deep plowing, then dig trenches and apply fertilizer to increase soil fertility. At this time, it is not advisable to water, because watering will cause the soil to harden, seriously affecting the growth of watermelons.
2. Seed Selection and Soaking
The selection of watermelon seeds is closely related to yield. When selecting seeds, we must choose from a reputable seed market, and select suitable varieties according to local market demand and the environment. After selecting the seeds, soak them in warm water for about 10 hours to break the seeds' dormancy period. Then soak the seeds in a medicinal solution for about 2 hours for sterilization and disinfection. Finally, wrap the seeds in a wet cloth and place them at a temperature of about 22-24 degrees for germination. Spray an appropriate amount of water every day to maintain humidity. When about 90% of the seeds have sprouted, they can be sown.
3. Timely Sowing
After the seed preparation work is done, sow at the appropriate time. First, dig sowing holes in the seedling bed, place about 3 seeds in each sowing hole, and control the plant and row spacing at about 4cm. After sowing, do a good job of management by covering with a layer of fine soil and then a layer of plastic film. Do a good job of regulating the temperature and humidity of the seedling bed. If the temperature fluctuates greatly, then you also need to cover the seedling bed with a layer of straw to improve the soil's heat preservation capacity and promote seed germination. Before the seeds break through the soil, be careful not to ventilate, so as to avoid hindering seed germination.
4. Daily Management
After the seeds emerge, do a good job of ventilation. When the seedlings grow to about 5cm, carry out proper hardening of the seedlings to improve the growth ability of the seedlings. Then prepare nutritional pots filled with humus soil and transfer the seedlings into the nutritional pots. Remove seedlings with weak growth, poor growth, or pests and diseases. After all have been transplanted, water promptly to ensure healthy growth of the seedlings. Then control the temperature at about 20 degrees. The nighttime temperature should not be lower than 18 degrees, otherwise it will inhibit the growth of the seedlings. The daytime temperature should not exceed 26 degrees, otherwise it will cause the seedlings to grow excessively and reduce the survival rate after planting. Finally, when the seedlings grow to about 11 cm, carry out the transplanting work.
The above is a brief introduction to watermelon sowing and seedling raising techniques. Watermelon sowing and seedling raising techniques directly determine the growth ability and yield of watermelons, so everyone must pay close attention! That is all for today's introduction.
