Sowing density should not be too large to avoid seedling crowding after seedling emergence: For example, solanaceous vegetables are generally 667 square meters. Daejeon requires seeding beds of 2 to 3 square meters and seeds of 15 to 25 grams. At the same time, ground cover was removed in time after about 30% emergence. Timely seedlings, planting and planting: Solanaceous fruit should be seeded after the emergence of seedlings, generally should be 2 to 3 times; in the seedlings, "two leaves and one heart" should be carried out when the planting, the density of the implant is controlled at 120 ~ 130 Strain / square meter. Strengthen ventilation and light transmission, and control temperature and humidity: After exhumation of the seedlings, pre-implantation, post-implantation and post-planting, all ventilation and light transmission should be carried out, temperature and humidity should be reduced, exercise at low temperature should be strengthened, and excessive growth of seedlings should be controlled. Rational management of fertilizer and water: In the preparation of nutritious soil, attention should be paid to the amount of phosphorus and potash fertilizer and the amount of nitrogen fertilizer should be controlled. Strict control of moisture and topdressing in the seedbed requires topdressing nitrogen fertilizer when dressing is required. Timely sparse seedlings: eggplant, melons, about 20 days before planting, seedlings often appear overcrowding phenomenon, this time should be appropriate to move the seedlings to separate the size of the seedlings, and expand the living space of the individual. Pharmacy control leggy: In addition to taking the above-mentioned measures, once the emergence of seedlings grows, it can be sprayed with 0.2% Bordeaux mixture (equal volume) or sprayed with 50% chlorcholine 2000 to 2500 times.
