2. Handle the seeds. Before sowing, open the seed bag, remove the seeds and sterilize. Wash the seeds several times with clean water, wash the seeds off the surface of the debris and germs, and then soaked.
3. Control temperature and humidity. The night temperature at nursery is 10, -, and 15 degrees Celsius, so as not to form leggy seedlings. The soil moisture before seedling excavation is not too large. The water content of bed soil suitable for vegetable seedlings is 60%-80% of the soil water holding capacity. Otherwise, not only poor air permeability is not conducive to emergence, but after the emergence of pests and diseases is more serious. '
4. Apply seedlings. Jinbao root Miao Zhuang is a protective agent for vegetable seedlings. It can be mixed in nutritious soil or in the colonization, transplanting, mid-to-late growth stage, watering, rooting and foliar spraying to increase ground temperature, early germination, and promote weak seedlings. Strong seedlings. When planting and transplanting, the seedlings are quickened and rooted, and they enter the high-yield farmland in advance, and can prevent leggy, prolong the harvest period, and resist disease and stress.
5. Reduce the density. Appropriately reducing the density allows the seedlings to fully receive light and develop into strong seedlings.
