At present, the market for tomatoes is good, not only in the area of ​​planting, but also in scale. However, it is easy to grow tomatoes, and it is still necessary to learn to grow high-quality tomatoes. Let's take a look at the tomato cultivation method of 60,000 jin per mu. First, variety selection 1. Technical requirements. Tomatoes should be of infinite growth type and have the characteristics of low temperature tolerance, low light and disease resistance. 2. Reference varieties. Caruso, Zhongza No. 9, Zhongza No. 11, Jiafen No. 15, Pink Queen, etc. Second, nursery 1. Technical requirements The nursery environment is good, disinfected, insecticidal treatment, and isolated from the outside; seedling method using 72-hole tray for soilless seedlings, seeds should be disinfected; seedlings start from early to mid-July, the seedling age is controlled in about 25 days; The seedling height is less than 15cm, the stem is about 0.3cm thick, and the leaves are 3 leaves and 1 heart. 2. Operating procedures 1 seedling substrate preparation. Prepare the seedling substrate with 50% of each of the charcoal and vermiculite, and disinfect the dried chicken manure + 0.5kg special fertilizer (prepared by the company) according to the cubic meter Skg, mix the fertilizer evenly, and put it into the tray for use. 2 seed treatment. After soaking in 55 ° C water for 10 min, remove the drained water, soak it in 1% potassium permanganate solution for 10~15 min, and wash it with water. Soak in clean water for 6h. 3 germination. The treated seeds are taken out and placed under the conditions of 28-30 ° C °C to pay attention to moisturizing and washing the seeds every day during germination and germination. 4 sowing. The tray containing the substrate is poured into clear water, and the seed is germinated, and the seeding depth is about 1 cm. After sowing, pay attention to prevent high temperature and drought, keep the ambient temperature at 25~28°C during the day and 15~18°C during the night, and maintain the matrix relative humidity at 80%. Measures for cooling can be done by shading net shading, double-layer wet newspaper covering seedling trays, etc. 5 seedling management. After emergence, the temperature during the daytime is maintained at 22~25°C, and at night it is 12~15°CC; the light intensity is greater than 30000lx; the relative humidity of the substrate is maintained at about 80%. The cooling measures are shading net shading, leaf surface spraying, etc. ESU pencil,Monopolar cautery pencil,Diathermy pencil,Bovie pencil 2 MEDS TECHONOLOGY CO.,LTD , https://www.2-meds.com
