Techniques for Preserving Fresh Cherry Tomatoes in Spring
The Saint tomato, native to Taiwan, is a type of cherry tomato, which is mainly eaten with fresh fruit. For early spring cultivation, a plastic greenhouse with a span of 6 meters can be used to raise the seedlings in mid-November and planted in February of the following year. Fresh fruit can be harvested in early May and 6000 kg of fresh fruit can be produced per mu. First, seed treatment. In order to prevent the dissemination of seed bacteria, the seed before sowing should be disinfected, soaked with warm soup, or soaked with chemicals. The soaking of warm soup is soaking the seeds of the soaked fruit in cold water for 10 minutes, and then putting it into hot water of 50-55°C to stir continuously so that the seeds will be evenly heated, and the hot water will be replenished at any time to make the water temperature stable. 15- After 20 minutes, remove and put heat in cold water, then soak in warm water at 25-30°C for 4-6 hours. Seed soaking with seeds is wrapped in gauze, soaked in 10% aqueous solution of trisodium phosphate for 20-30 minutes, then remove the seeds and wrap them in a wet towel at 25-28°C. During the germination, the seeds were rinsed with warm water of about 25° C. for 1-2 times a day, germination was initiated for 2-3 days, and sowing was possible when 50% of the seeds were dewy. Second, sowing nursery. Firstly, prepare the seedbed to be watered. After the water is soaked for 2-3 hours, sow the seeds evenly and cover 0.5-1 cm of nutritive soil. The amount of seedlings per square meter of nursery bed is 3-5 g. Need 8-10 square meters nursery bed. After sowing, the film is covered with heat and moisture, and the film is removed immediately after emergence. The management of unmarshalling fruits from seeding to cotyledons is mainly to create environmental conditions suitable for seed germination and emergence, and to achieve Miao Qi, Miao Quan and Miao Zhuang as soon as possible. Third, timely transfer seedlings. When cherry tomatoes 1 leaf 1 heart, grab the sunny day at noon and transplant them into the nutrition bowl. The nutrient soil is dominated by adequately decomposed organic fertilizers, and the amount of phosphate fertilizer and the appropriate amount of nitrate-applied nitrogen fertilizer are appropriately increased. To ensure sufficient nutritional area, it is best to use 9 cm 9 cm nutrition to protect the root system. The principle of nursery management during seedling seedlings is to have proper temperature, humidity and sufficient sunlight. This is achieved by covering the insulation, removing the light from the membrane, fertilizing the water, and expanding the nutritional spacing. Fourth, colonization. When the seedling grows 7-8 true leaves, it colonizes (can plant with buds). Each colony was colonized with two rows of plants, 60 cm in small rows, 40 cm in spacing, and 2,000 colonizations per acre. The depth of colonization is appropriate for the level of cotyledon and the planting water should be poured. Cover the mulch after colonization. Cut the membrane according to the length of the surface and the length of the buried soil at both ends. Then, cut the cut mulch between the two rows of seedlings, and then pull the mulch horizontally to the furrows on both sides. Finally, tighten and compact the membrane. Field management such as watering, topdressing, temperature management, and uncovering greenhouse films are equivalent to conventional early spring tomato cultivation. Diseases and pests are lighter and may not be controlled. Fifth, pruning. The cherry tomatoes grew rapidly in the greenhouse, and the plants were tall and erect. When the plants grew to 30-40 cm, they should be trussed with vines or hanging wires to prevent lodging. Strong collateral growth, can use multi-layer and continuous two-layer pruning, that is to retain the inflorescence on the trunk, leaving the side branches issued on the trunk, leaving two inflorescences on each side branch, and then leave two leaves in the inflorescence topping. It is necessary to fight in time and twist branches on the side branches so that the side branches do not shading each other. Twisting branches are generally performed on a sunny day. The old yellow leaves and diseased leaves that are yellowed are promptly removed to reduce nutrient consumption and enhance light transmission. Six, dip the flowers and fruits. Poor pollination in early spring when the temperature is low and easy to drop flowers, can be used 2,4-D freshly opened flower buds and flower stalks (marked with red advertising color), or the order of the opening more neat and then in the 2,4-D solution Touch it. VII. Harvesting. Due to the high fructose content of the Virgin, harvesting can only truly reflect the inherent flavor and quality when fully cooked. Therefore, it is appropriate to harvest. Keep sepals and a fruit handle when harvesting.
