How to cultivate high-yield watermelon seedlings
Soaking seeds and germination before planting. Firstly, the watermelon seeds should be disinfected, and then immersed in the new high-fat membrane mother liquor to keep warm, moisturize and swell, and improve the germination rate of the seeds to make the seedlings strong. Repel underground pests and isolate viral infections. After seed soaking, the seed coating agent is used for germination, and after sowing, it is sown. A germinated seed is planted in the center of each nutrient or nutrient block, and the soil is about 1.5 cm thick. The covering soil should not be too shallow, otherwise it will easily dry the young shoots. Seedling management. After sowing, insert a bamboo arch every 50 cm on the seedbed, covered with silver-gray nylon gauze, and cover the plastic film to prevent rain in rainy days. Uncover the film ventilation on sunny days. In order to prevent direct sunlight from seedlings, the shade can be properly shaded when the sun is strong at noon. When the aphids are found on the seedbed, they are immediately treated with chemicals. Ensure that the seedbed sees dryness and avoids excessive moisture or drought in the seedbed.
