How to determine the Seedling stage of Watermelon
The direct seeding or planting time of watermelon with plastic film mulching is 10 cm deep, the soil temperature stably passes through 15 ℃, the daily average temperature stably passes through 18 ℃, and the sowing time is 25 to 30 days earlier from planting seedlings to the premise. The seedling sowing time of single-layer greenhouse, greenhouse plus small arch greenhouse and greenhouse plus grass mulch was 40 days, 50 days and 60 days earlier than that of plastic film mulching, respectively. Second, it is very important to determine the sowing date according to the weather forecast, especially the one-week weather forecast. For the seedbed without heating facilities, we should choose to sow seeds in sunny weather for about one week; for the seedbed with heating conditions, sunny day is the best choice.
