Now, vegetable growers who are ready to plant early spring watermelons have begun to grow seedlings. According to the author's observation, the depth of the nursery bed used by the melon farmers is equivalent to the height of the trays. However, in order to facilitate the placement of the trays, the width of the seedbed is 5~10 wider than the length of the two trays. After centimeter, after the melon farmers put the plugs, the edges of the trays and the edges of the seedbed will have gaps, so that the water retention at the edge of the nursery bed is reduced, and the matrix is ​​prone to water shortage, resulting in uneven emergence. The melon farmer can cover the soil around the seedbed and fill the gap between the plug and the seedbed, so that the water retention capacity of the whole seedbed is consistent, which is conducive to the emergence of neat seedlings. Of course, melon farmers can also fill the gap agricultural papers with waste mulch or straw around the seedbed to enhance the water retention capacity around the tray and ensure that the seedlings are unearthed.
