The field tomato cultivation technique, the field tomato cultivation technique, is known as the field tomato cultivation technique, known as sour soup and tomatoes, originating in south america and suitable for planting in most parts of our region. Tomatoes are temperamental, frost-free, light-free, heat-averse, growable at 20-25°c below 15°c, slow growth, fertilization, stunted development, stop growing at below 10°c, die at below 1-2°c, significantly reduce time co-operation at high temperature 30°c, stop growing at above 35°c, appropriate soil acid alkalinity ph value 5. 5~7. 1. Selection of healthy, disease-resistant species. In the early spring, a variety of types are chosen, including 16, ruby, summer autumn, ruby ii, kimyang, plateau and diamond ii. 2. Cultivate seedlings. (1) pre-selection as an unplanted eggplant crop, with a backwind to the sun, high soil fertility and plots adjacent to the field as seedbeds. It is also fine-tuned and fine-tuned, 1m wide, 0. 4m wide, 10-20 g per acre field, 15-20 square m. Per square m seedbed 4 kg + phosphorus 0. 2 kg + 25% mercuric humid powder 6 g + fine earth 6 or so in two thirds the soil is soaked with water, then seeded with disinfected seeds, a third of the medicine is planted on the seeds, a layer of coverings such as pine hair is covered, and light water is sprayed based on wetness, with the arch shed being used for seedling in the early spring. (2) sterilization of seeds: 30 minutes of warm water permeation to constant temperature, 6-8 hours of sowing; 5 minutes of 0. 2 per cent of methyl tobuzin leachation, and then wash with fresh water and mix with appropriate grasswood ash. (3) seeding
