Instead of plastic floppy disks or other spacers, special smashing trays are used to raise seedlings, which are called simmering trays. The tray is a seedling tray designed to adapt to seedling cultivation and is made of plastic plates. The seedlings bred from the seedlings have soils that are not easily disintegrated and separated from each other and are easily transported. There are basically four ways to sow seedlings:
Seed mixed sowing. Mix the seed buds with the nutrient soil in proportions and place them on a sampan plate. Scrape the plate with a wooden board, and then cover with a thin layer of cover soil after watering. There should not be too much earthwork, and there should be no soil between the holes to prevent the rooting of seedlings in later stages and affect the quality of casting. This method is relatively simple, labor-saving, sowing speed. However, the seed has different depths in the boring hole, and the emergence of the seedlings is less uniform, and at the same time it is easy to see blind holes in individual carcasses.
Sow after soiling. Put the soil first, water it, then spread the seeds evenly on the surface of the disk, use the board to put the seeds into the mud, and then cover the soil. This method has good sowing quality, consistent seeding depth, no blind hole phenomenon, but slower sowing speed.
Mud sowing method. This method is suitable for areas with heavy sand and soil. First, the prepared nutrient soil and paste into the borehole, and then evenly sow the seeds into the mud and then cover the soil. This method is conducive to sandy loam soil conservation and seedling cultivation.
Seeder method. The dislocation of the hole or the fixed seeding device is used to align the seeding disc, and the upper layer of the seeder is pulled. The rice can be dropped into the loquat. This method seeds no blind holes, the number of seedlings per hole is uniform, and the emergence is neat.
Seedlings nursery field management. Seedling nursery management and floppy seedlings are basically the same. The difference is that first of all, it is necessary to carry out the exfoliation treatment before the seeds are selected. The mango and branches of the mango are to be taken off to ensure that the seeds are not empty when sown, and the seeds are sown well. Second, we must pay attention to the control of physiological bacterial wilt in the management of Miaotian. The bottom water must be poured before sowing. Due to the small holes in the plate, the soil is less and it is easy to dry out and affect the emergence. The emergence of water after the emergence of seedlings is easy to get blight. Seedlings after seedlings have to be poured once with water, with the seedlings growing, the number of replenishment should be appropriately increased. Watered once every two days. After the removal of the membrane, the evaporation of the soil on the bed is increased, and groundwater is properly diluted to prevent dehydration and dryness. One day before throwing, water must be poured to facilitate lifting.
