Roots of greenhouse vegetable seedlings is a physiological disease, mostly caused by improper management. At the time of initial infection, rust appeared in the roots. In severe cases, the roots were rotted, and no new roots were found. The seedlings turned yellow and wilted, and all of them died later.
Keep the temperature of bed soil to be reasonable, and ensure sufficient soil temperature after seeding. In case of rainy days and insufficient light, warming and heat preservation measures should be taken. Autumn and winter nursery seedlings (rooms) in the best use of electric hotbed for nursery, in order to facilitate insulation.
Timely dehumidification in greenhouses or greenhouses and other places of protection when the seedlings, the general seedbed is not obvious drought (above the surface of the group does not scattered groups) when not watering, should be as little as possible watering or not watering; obvious drought when the amount of watering should not be too Big. Seedlings in the nursery are dry and not wet. If the seedbed is too dry, it can cover moist fine soil. This will not only relieve the seedlings' need for water, but also reduce the air humidity in the seedbed.
Before adding light to grow seedlings, choose a place with sufficient light to build a seedbed. This is conducive to the seedlings robust growth and development, enhance their resistance to disease, reduce the emergence or spread of roots in vegetable seedlings.
Prompt ventilation After the cotyledons are unfolded, select clear and warm weather to uncover the ventilation of the cover, and evenly spread a layer of fine dry soil to the seedbed, then cover the cover tightly. This will not only reduce the humidity of the bed soil, but also increase the temperature. effect.
Apply rooting agent to take 50 ml of rooting agent and dilute it 10 to 20 times. Mix 50 kg of nutrient soil or 4 to 5 square meters of seedbed and sow. It can promote seed germination, consistent emergence and no weak seedlings. Use at seedling stage: After seedling stage, ie after 2 leaves and 1 heart, the rooting agent per square meter will be sprayed or sprayed with 30 to 10 kg of 30 times liquid, which can obviously promote the elongation of the main root, increase the number of lateral roots, and strengthen the root system. Vitality and absorption intensity, to avoid rot and form strong seedlings.
