As the saying goes, "miao seedlings are good and a half." Cultivation of age-appropriate seedlings is one of the most crucial technical measures to achieve early quality, high yield and high efficiency of eggplant. First, the determination of the sowing date In order to obtain better economic benefits, can be sown in late July-September, to catch up in late November and December. Second, the choice of seedbed 1, cultivation of eggplant seedlings must choose a higher ground, drainage well, close to Datian, convenient management, and in the last two years did not plant eggplant vegetables fields. 2. In general, bed soil for cultivation of eggplant seedlings must be fertile, rich in all kinds of essential nutrients, suitable pH (6.8-7.3), good granule structure, strong water holding capacity and good ventilation conditions. . Third, the establishment of a seedbed, eggplant standard seedbed, generally 10 meters long and 1.2 meters wide. Should be made as early as possible after the harvest to deepen as early as possible in order to facilitate the baking soil, soaking soil and sun; before the seedbed, but also lime or use soil disinfectant disinfection. 2, commonly used methods of disinfection are: (1) formalin (40% formaldehyde) disinfection. The bed soil was sprayed with a 100-fold dilution of formalin. The dilution of 1 kg of formalin was used to treat 4000-5000 kg of bed soil. The bed soil should be mixed well after spraying, and the covered plastic film should be tightly closed for 1-2 days. After the film is removed, it can be used after 6-7 days until the medicine gas is dispersed. The law is mainly to prevent damping-off. (2) Disinfection of pentachloronitrobenzene. Mix 70% pentachloronitrobenzene powder with 50% thiram or 65% zeocin wettable powder. Mix 1 cubic meter of soil with 0.12 kg to 0.15 kg of this mixture. First mix 15 kg of dry fine soil into the soil and mix it evenly in the culture soil. This type of culture soil is best used as a paddy soil and cover seed soil to prevent damping-off and blight. Fourth, seed treatment and sowing 1. Seed treatment in order to promote emergence and prevent diseases, eggplant must be seeded before sowing. The main measures are to break the dormancy, soak in warm soup, and sterilize pharmaceuticals. (1) Break the dormancy: In order to timely sowing and promote the emergence of seedlings, we must break the dormancy. The commonly used method is to use gibberellic acid (90% O2) before soaking. The concentration is 200-500ppm and the treatment time is 8 12 hours. (2) Soaking seeds in warm soup: Use 55°C warm water to soak seeds, and keep stirring. After keeping the water temperature for 15 minutes, transfer to 30°C normal temperature water for 8-10 hours. Soaking seeds with warm soup can kill germs attached to the seed surface and a part of the seeds that are lurking inside the seeds. (3) Disinfection and soaking of pesticides: carbendazim soaking. Soak the seeds in fresh water for 1 hour, then soak in 50% carbendazim 500 times for 7 hours. Rinse with water afterwards. This method can prevent verticillium wilt and blight of eggplant. Can also be used formalin, mercury or water (permanganate) and other liquid soaking disinfection. 2. The seedbed should be poured into the bottom water the day before sowing and sowing, and if it is planted in the afternoon, it can also be watered in the morning. The watering standard requires that the soil layer within 8-10 cm is moist, so that it can be maintained until the emergence. Do not have to water. Sowing should be adopted sowing method, in order to make the seeds broadcast evenly, the wet seeds can be mixed with some fine soil, fine coal ash or charring chaff and then sowing. When planting, first loosen the top soil and spread it evenly back and forth. After sowing, it is necessary to timely cover 1 cm thick high-quality culture soil, cover the straw, and build a simple scaffold to cover the shade net. Fifth, seedling management (1) fertilizer and water management. Fertilizers were applied 2-3 times throughout the seedling stage, mainly phosphorus and potash fertilizers, followed by nitrogen fertilizers to prevent leggy growth. Cow urine has a good promoting effect on eggplant, and 15%-25% cow urine can be poured into water. The seedling stage is in a period of July-September with high temperatures and typhoons and rainy seasons. Attention should be paid to watering and drainage work. Watering should be done at dusk to keep the soil moist and drain well when it rains. (2) and time seedlings. When the seedling grows 1-2 true leaves, the seedlings should be planted to keep the seedlings 6-8 cm square. Sub-seedlings should be selected on sunny days, so that transplanting with soil, reducing root damage, watering in time after transplanting. For seedlings of nutrition, fill the gaps between the days with fine soil. (3) Pest control. During the seedling stage, it is prone to damping-off, blight, and wilt disease. It can be used as a 450-fold solution of 15% hymexazol, 5% formic acid, 800-fold solution of Mn-Zn wettable powder, 750-fold of fungicide, and 36% Bacterial enemy 500 times and other liquid control. Insect pests include red spiders, tea aphids, aphids, and 28-spot ladybugs. They can be used for 1500-times, 2,000-times for killing cockroaches, 1500 times for 10% nets, 1500 times for 6% biks, and 3% for acetamiprid. 1500 times, 1500 times more than 10% of worms, 2.5% of 2.5% Kung Fu EC, liquid exchange control.
