Eggplant planting is delayed, and it is not easy to get out of the seedlings but it is uneven. Is this what happened? The following small series will tell you about the common problems and control measures of eggplant seedlings. Eggplant does not sprout First, the maturity of the eggplant is not neat: the seed with good maturity first emerges, and the seed with poor maturity emerges. Second, the seedbed temperature is low: the normal germination temperature of eggplant seeds is 25 ° C ~ 32 ° C, the bed soil temperature is lower than 15 ° C, the seed will emerge slowly. Third, the sowing is too shallow or too deep: the thickness of the suitable covering of the eggplant is about 1 cm, the thickness of the covering soil is less than 0.5 cm, the seeding is too shallow, the seed is delayed due to insufficient water absorption; the thickness of the covering soil is more than 1 cm, the seeding is too deep, and the seedlings are unearthed. Also relatively extended or out of stock. 4. Excessive fertilization in the seedbed: Excessive fertilization causes the seed buds to be burned, reducing the growth potential of the embryos, resulting in slow emergence or emergence of seedlings. 5. Seedbed knot: The seedbed knot will cause insufficient oxygen content in the soil, resulting in slow growth of the embryo, delaying germination; prevention of seedbed compaction, 50 grams of turpentine per cubic soil, pouring foot water, no watering or less at the emergence stage Watering. Hat seedling The main measures to prevent the occurrence of "wearing caps": 1. Use a full fresh seed with strong germination power; 2. Pour enough water to keep the seedbed in sufficient water; 3. Master the correct seeding depth of the seeds; 4. Keep the topsoil of the seedbed moist after sowing, especially in the high temperature period; 5. In the early stage of seed emergence, “wearing cap seedlings†is found. If it is caused by shallow sowing, a layer of 0.5 cm thick sieved wet fine soil can be evenly distributed to the nursery; 6. If it is caused by seed, when the seedlings are just unearthed in the morning, remove the seed shell by hand; 7. Spraying plant conditioner 1000 times at the same time to increase the disease resistance of eggplant seedlings. Malformed seedling Malformed seedlings mainly refer to leaf malformed seedlings and heartless seedlings. The reason for the occurrence of malformed seedlings is mainly seeding with Chen seeds or damaged seeds; the temperature inside the seedbed is high, the water loss is fast, the bed soil is easy to dry, and the seed bud injury is prone to deformed seedlings. Prevention: Seeds are selected before sowing; seedlings are found to be dry after sowing, and watering can be appropriately applied; foliar spray application of plant conditioners improves resilience. High seedling It is caused by high temperature and humidity in the seedbed, insufficient light, excessive seeding density in the seedbed, and crowded seedlings. Prevention: 1. Extend the natural light time of the seedbed as much as possible to inhibit the growth of seedlings; 2. Appropriately reduce the temperature of the seedbed. When half of the seedlings in the seedbed are unearthed, the temperature of the seedbed should be reduced to about 25 °C during the day, and the night temperature should not exceed 15 °C, and appropriate ventilation and cooling measures should be taken; 3. If the density of the seedlings in the seedbed is too large, the seedlings will be crowded, and the seedlings should be opened early; 4. Strengthen seedbed management and timely fertilize and supplement nutrients. The above is a small series of analysis on the reasons for the emergence of eggplant and the solution to common problems in eggplant seedlings. Have you learned it?
