What issues should be noted in watermelon seedling management? (1) Temperature management: In temperature management, two tendencies should be avoided. One is not daring to remove the film for ventilation, fearing the seedlings will freeze, which results in high temperature and high humidity in the seedbed and causes the seedlings to grow leggy; the other is too much ventilation, which makes the temperature inside the bed too low, causing slow seedling growth...

How to prevent and control watermelon seedling diseases? A detailed guide to integrated control techniques
I. Symptoms of the main diseases 1. Damping-off. In the early stage, the root collar of the seedling (the junction of root and stem) develops lesions that look as if scalded by boiling water and become rotten, after which the diseased part turns yellowish-brown, dries out and shrinks; the cotyledons have not yet wilted, but the seedling topples over. Damping-off mostly occurs from the emergence of the cotyledons to the stage when 2 true leaves have flattened out. The disease spreads very quickly; a few days after the appearance of the first diseased plants, seedlings topple over in patches. Under conditions of high temperature and high humidity, the diseased parts of the seedlings and the ground nearby,

Four key steps to master for raising watermelon seedlings in a heated hotbed
Raising watermelon seedlings in a heated hotbed has the characteristics of fast warming, even temperature, low cost and simple operation. It can cultivate robust watermelon seedlings in January and February when the air temperature is very low, and its seedling-raising effect is similar to that of an electric heating hotbed. 1. Build the seedbed. First dig a bed pool 4.5 m long from east to west, 1.6 m wide from north to south and 0.2 m deep...
