Dongkan High-efficiency Agricultural Demonstration Garden in Binhai City, Jiangsu Province, has been used to cultivate tomatoes in high-yield one-year, three-year-old cultivation techniques in sunlight greenhouses in recent years, and has achieved ideal output and economic benefits. The annual output of tomatoes is more than 15,000 kilograms per mu, including 5,600 kilograms per mu after the fall, 5,000 kilograms per mu in the winter, 4,500 kilogrammes per mu in the spring, and a total of 28,000 yuan per mu. Its high yield cultivation techniques mainly include the following points:
First, the mouth arrangement. The first quail is the tomato in winter and spring, sowing time is in early November, colonization time is mid-January, and harvest ends in late April. The second is the summer tomato, sowing time in mid-April, planting time in late May, the end of August harvest. The third crop is the late autumn tomato, sowing time in late July, planting in late August, and harvesting in late November.
Second, the choice of species. The first tomato selected cold and disease-resistant high-yielding species of the United States No. 4, Dongsheng, Xinguan F2, etc.; the second choice of tomato selection 1857, rich, good powder, etc.; the third choice of tomato selection L402.
Third, germination sowing. Soaking with warm soup before sowing, and then germination under the environment of 25 ~ 26 °C. When the shoots grow to the size of the needle tip, seedlings are sown and the germinated seeds are sown uniformly on a bed of irrigated nursery, covered with 0.8 cm thick nutritious soil. After sowing, 2 leaves and 1 heart are seedlings. At this time, the temperature is required to be 25 to 30°C during the day and not less than 20°C during the night. When the seedlings grow 5 to 6 leaves, they can be planted. The seedlings are cultivated for 5 to 7 days, during the period of hardening, 20 to 25°C during the day and 15 to 18°C ​​at night.
Fourth, soil fertigation. Before planting, 7500 kg organic fertilizer was applied per mu, and 100 kg of active calcium fertilizer was used. Two-thirds of them were used for combined deep-turning with 30 cm of Pusch, another one-third with 25 kg of diammonium, 70 kg of potassium sulfate, and zinc sulfate2. Kilograms and borax 1.5 to 2 kilograms were mixed and applied into the planting ditch.
Fifth, rational close planting. The suitable row spacing should be 0.3 meters and 0.6 meters in row size, and 3,700 rows per 667 rows.
Six, fertilizer and water management. Planting water after planting. 4 to 5 days after planting, depending on the soil moisture, the seedling water was poured, and the watering amount was suitable for small water. After easing the seedlings, the seedlings are planted, controlled, promoted flowering and fruit setting, keeping the stems and leaves strong and not prosperous, and the root system developed. When the stems and leaves grow slowly, the leaves are thin and dark, and the first ear grows to the size of the table tennis, the end of the seedlings begins to top-dressing and watering, applying 20 kg of compound fertilizer and 10 kg of potassium sulfate per mu. From then on until the fruit was harvested, the soil was kept moist and wet. To prevent cracking, the amount of watering must not be changed.
Seven, hormones protect fruit. When more than 2 flowers per panicle were sprayed with anti-droplet, concentration was used as reference, and 0.1% sucrose was added to prevent gray mold. It is better to spray the flowers before 10 o'clock in the winter and spring. Xia Yun and Qiu Yan later decided to spray flowers after 4 pm on a sunny day.
Eight, timely pruning. Use a single rod technique. In spring and spring, 3 spikes are reserved, and 3 leaves have 3 leaves topping. After the summer and autumn leaves, 2 spikes were reserved and 3 leaves were picked on the 2nd ear, and the side branches were removed timely. Leave 3 to 4 fruit per panicle. In order to prevent prosperous growth, it is appropriate to use appropriate doses of herbs according to seedling growth during the growth period. When the seedlings grow to 12 leaves, and the spacing between the top and bottom ears is more than 7 cm, Dwarkathing Spray 250 g of the drug per 667 g of soil around the rhizosphere.
Nine, temperature and humidity. Colonization to a mild seedling stage, 28 to 30°C during the day and 18 to 20°C at night. Slow seedlings to flowering period, during the day 20 ~ 25 °C, 14 °C at night. Flowering to fruit setting, during the day 23 ~ 28 °C, 15 °C or more at night. Set fruit to coloring period, during the day 20 ~ 25 °C, 15 °C or more at night. Coloring to fruit harvest, 25 °C during the day, 18 °C at night. The relative humidity of the air is required to be about 60% throughout the growth period. Pay attention to ventilation and humidity to control the occurrence of diseases.
Ten, timely pest control.
