Soil selection. A good ecological environment is the primary condition for the development of pollution-free agricultural products. Non-pollution summer tomatoes should try to choose away from the road, no factories and mines, pollution-free rivers, fresh air, cool climate, sandy loam area with large temperature difference between day and night.
Land clearing and disinfection. Prior to planting, combined with deep-spotting, weeds and weeds were removed from the field to eliminate pest transmission media and hosts, and remove soil-based membranes, pesticide bottles and other wastes. Disinfect the soil, use 65% mancozeb manganese per mu, 21 kg mixed fine soil 15 kg spread on the surface, can effectively prevent a variety of seedling disease.
Variety selection. Use high-quality, disease-resistant, insect-resistant, and good-quality varieties that are adapted to local conditions.
Seed treatment. Before sowing, the seeds were soaked in warm water of 55°C for 10 minutes, washed with clean water, and then germinated under a condition of 25-30°C with a damp cloth to inactivate viruses to reduce the occurrence of viral diseases.
Reasonably manage fertilizer. Fertilization is mainly organic fertilizer and formula fertilization is applied. Each mu of quality manure mulching 5000 kg of anaerobic fertilizer, 30 kg of urea, 200 kg of plant ash or potassium sulfate 20 kg, 1.5 kg of zinc sulfate base fertilizer. Top-dressing method with light weight and chase after top dressing is adopted. During the first period of fruit enlargement, topdressing ternary compound fertilizer is 25 to 30 kilograms. After each harvest, one fruit is chased and one fertilizer is applied. Each application of urea is 10 kg. . Alternately spray potassium dihydrogen phosphate, borax, etc. from the first ear.
The soil temperature during summer tomato growing season is relatively high, and the virus develops quickly. The watering method should be based on the method of pouring water in small wells, that is, using clean deep well water and watering before 9:00 in the morning, which can play a role in moist soil and lower ground temperature. At the same time, keeping the soil moist at the same time can reduce the occurrence of split fruit and umbilical rot. Pay attention to timely drainage in the rainy season.
Cultivate the soil and cool the grass. After planting and rejuvenating the seedlings, timely cultivating and weeding, and ridge raising and soil-cultivation, after planting soil, 300-500 kg of wheat stalks are evenly spread on the rows, which can improve the microclimate in the field, reduce the temperature of the soil, preserve drought, inhibit weeds, and increase soil organic matter content. The application time is usually after watering or before rainfall.
Disease prevention and pest control, leaf protection and fruit protection. During the growth of tomatoes in summer, they are prone to high temperature and rain, and many kinds of diseases and insect pests are prone to occur. In the production, as far as possible, agronomic cultivation techniques, mechanical measures, and environmental regulation should be combined to implement comprehensive prevention and control. When pesticides are selected, they can not only comprehensively control the damage of pests and diseases, but also reduce the pollution and harm of pesticides. The pesticides that are “high in one high, two low in one short,†(high in lethality, low in toxicity, low in residue, and short in residue period) are selected. When applying pesticides, follow the principle of “one major, two minor, and three appropriate†(to prevent mainly, use fewer drugs, use less drugs, apply methods, timing, and rotation are appropriate). The main insect pests in summer tomato growing season are cotton bollworm, aphids, and planthoppers.
BT biological preparation (sprayed with 250 grams per acre). The main diseases are viral disease, late blight disease and umbilical rot disease. The main agents used are 0.3-0.5% potassium permanganate solution, 70% thiophanate-methyl wettable powder 1000 times solution, and sprayed once every 10 days. . 7 to 10 days before fruit picking is no longer applied. The harvested fruits are rinsed with water and then sold to achieve fresh, tender, and non-pollution purposes.
Food made from fresh fruits that are sun-dried or dried. The moisture content is less than 12%, which is easy to preserve. For direct consumption or reproduction of food. A food made from peach, apricot, plum, jujube or melon, ginger and other fruits and vegetables, and then processed with sugar or honey. In addition to being eaten directly as a snack or snack, candied fruit can also be used as a decoration on cakes, biscuits and other snacks.
