The increase in yield and income of vegetables also depends on seedlings. For many years, the main reasons for the unsuccessful cultivation of vegetables in some localities or poor returns were mainly due to the poor quality of cultivated seedlings, strong seedlings with strong resistance, low incidence of disease, and early results and high yields. Therefore, we often say: "Half the seedlings are harvested, and the strong seedlings will receive more than half." It can be seen that the cultivation of age-appropriate seedlings is the most important aspect of current vegetable production.
First of all, the selection is the key should choose the formal units and reputable units and university research units to buy seeds. Before sowing, after opening the seed bag, the seed is further selected, the seeds are removed, and the seeds are sun-dried and sterilized. Then wash the seeds with clean water several times to further wash away the impurities on the seed surface and reduce the adsorbed bacteria, and finally soak the seeds.
Again, pay attention to good temperature and humidity when the night temperature can not be too high, so as to avoid the formation of leggy seedlings. The soil moisture before the emergence of seedlings can not be too large, otherwise it is not only bad permeability is not conducive to emergence, but after the emergence of pests and diseases heavier.
Again, seedlings are applied. Root seedlings are protective agents for vegetable seedlings. Mixing in the nutrient soil or in the colonization, transplanting, growth in the late stage of bed watering, rooting, foliar spray, can increase the temperature, germinate early, and promote weak seedlings into strong seedlings. When planting and transplanting, the seedlings are quickened and rooted, and they enter the high-yield period in advance. They can prevent leggy, prolong the harvest period, and resist disease and stress.
Finally, the density. In order to nurture strong seedlings, we must also pay attention to the density of seedlings and reduce the density to allow the seedlings to fully receive light and develop into strong seedlings.
