In recent years, farmers in Shangzhuang Town, Yandu District, Yancheng City have explored and developed a new efficient planting model for tomato and rice rotation in greenhouses. By 2005, 9600 acres will be popularized and applied. Generally, 5000 to 6,000 kilograms of tomatoes and 600 kilograms of rice are produced per mu.
Tomato breeding strong seedlings selected high quality and high yield, early disease resistance of Zhongza No. 9, Queen of Powder, gold powder 402, Kyoho crown and other varieties. The nursery consists of two stages: the first stage is the use of Yangshuo cold bed breeding seedlings from late November to early December. The amount of seed used per mu is 50-75 grams, and the seedbed is 5-6 grams per square meter. 10 to 15 days before sowing, adequate basal fertilization, film heating. Seal the positive osmotic film, moisturizing and warming seedlings. In the second stage, the sheds were planted and planted as seedlings. At the beginning of February, when there were 3 to 4 true leaves, they were planted on sunny days. Each mu of Daejeon's artificial bed was 45 meters long and 1.3 meters wide. 10 to 15 days before planting per acre applied 45% of ternary compound fertilizer 3 to 4 kg, 2 kg of urea, 250 to 300 kg of diluted feces water as basal, spacing is 13 cm. Fasten the small shed film and cover the straw curtain. Add two sheds and a shed. Seedlings at the seedling stage should be protected against freezing, dehumidification, and dampness. Apply appropriate amounts of 0.1% to 0.2% potassium dihydrogen phosphate solution to improve cold resistance. Strong seedling standard: seedling age 75 to 85 days, seedling height 18 to 20 cm, stem 0.5 to 0.6 cm thick, true leaves 8 to 9 buds.
Timely planting 10 to 15 days before planting per acre, apply 5000–6000 kg per acre, 45% 40 kg of compound fertilizer, do a ridge after applying a ditch, width 50 cm, spray fluocin, weeding, mulching, Warming up. In the middle and late March, the cold tail warmer was selected for sunny day planting, with 4,500 to 5,000 plants per acre. The plants were transplanted on the mulching film. The row spacing was 45 to 50 cm, and the spacing was 30 cm. Side sheds were planted and sheds were added. Grass cover, cover the night cover.
The pre-scientific management focuses on cold insulation and scaffolding. Flowering and fruitful application of fertilizer, flowering and fruiting, prevention and ventilation. Pay attention to the pruning of the old leaves in the later period, adhere to mixed spray of fertilizers to prevent premature aging. The film was peeled off in the middle and late March and early April. In the middle and late May, the film was removed. Pay attention to pest control.
Timely picking in the white mature period with ethylene elixirs ripening. The tomato can also be plucked, placed in a dip of 1000-2000 mg/kg ethephon, and allowed to mature at 25-28°C. It is listed at the end of April and early May.
Rice cultivation of age-appropriate cultivars selected Xudao No. 3, Yandao No. 8 and Yangdao No. 6 and other resistant and lodging-resistant varieties with moderate growth periods. Multi-seedlings and seedlings were cultivated using the dry bed breeding method, sowed in mid-May and transplanted in late June.
A reasonable group of starting points is expanded to reduce the density and establish high-quality groups. Plant spacing 13 cm, spacing 27 cm, 18,000 to 20,000 holes per mu, 80,000 to 100,000 basic seedlings per mu.
Scientific management of fertilizer and water to appropriately reduce the amount of base fertilizer, depending on the seedling growth situation may be depending on the seedlings, re-applied Baohuafei. When the number of seedlings per acre reached 70% to 80% of the ear sprouts, the seedlings were controlled.
Comprehensive prevention of pests and diseases before sowing with pesticide soaking, pay attention to the prevention and control of planthoppers, aphids, rice leaf roller, stripe leaf blight, rice blast and sheath blight.
