Cold Shed Tomato-Tomato-Celery

In recent years, the three-crop continuous cultivation system of tomatoes and celery in Angezhuang Town, Yinan County, has shown remarkable economic returns after several years of successful implementation. By 2008, each greenhouse (with a net area of 0.6 to 0.7 mu) generated an average profit of over 12,000 yuan, with some reaching as high as 16,000 yuan. This innovative planting method has proven highly effective, and the key technical aspects are outlined below: **First Crop: Winter and Spring Tomatoes** 1. **Variety Selection**: Choose varieties such as "US No. 4" and "New Secret," which are well-suited for the local climate. 2. **Nursery Timing**: Start sowing in late November to early December, and transplant seedlings into the greenhouse in mid-February. 3. **Soil Preparation and Fertilization**: Apply 5,000–8,000 kg of organic manure per acre, along with 30 kg of diammonium phosphate, 20 kg of potassium sulfate, and 2 kg of micronutrients. Deep plow the soil to a depth of 30 cm, then level it to create raised beds 10 cm high, 100 cm wide, and cover them with plastic film. Plant two rows per bed with a spacing of 23 cm between plants. 4. **Planting Time**: Transplant in mid-February, ensuring a density of about 5,000 plants per mu on sunny days. 5. **Field Management**: Maintain high temperatures during the day (30–32°C) and slightly cooler at night (18–20°C). Water once after 7 days of planting, and gradually lower the temperature to increase the day-night temperature difference. Remove the mulch early to promote vigorous growth and avoid weak seedlings. When more than 50% of the plants start blooming, perform fruit thinning to improve yield. When the first fruit reaches 2 cm in diameter, apply 10 kg of urea as top dressing. A second application of 15 kg of urea is done after the second set of fruits develops. Regularly monitor and manage pests and diseases to ensure healthy growth. 6. **Harvesting**: Begin harvesting in mid-April of the following year and finish by mid-May. **Second Crop: Summer Tomatoes** 1. **Variety Selection**: Use varieties like "1857" and "Warm Beauty" that are suitable for summer conditions. 2. **Nursery Timing**: Sow seeds in early May and transplant seedlings in late June, with a seedling age of around 55 days. 3. **Soil Preparation and Fertilization**: Apply 3,000–5,000 kg of organic fertilizer, 25 kg of diammonium phosphate, 15 kg of potassium sulfate, and 2 kg of micronutrients. Plow the soil to 30 cm, create raised beds 10 cm high, 100 cm wide, and cover with plastic. Plant two rows per bed with a spacing of 25 cm. 4. **Planting Time**: Transplant in late June, with a density of about 4,500 plants per mu. 5. **Management Techniques**: During hot weather, open vents on sunny days and use shade nets when temperatures exceed 30°C. Lay 10 cm of straw in the furrows to reduce ground temperature. Close vents during rain to prevent water from entering. Keep daytime temperatures between 25–30°C and nighttime temperatures between 16–20°C, with humidity controlled at 50–65%. Spray a solution of 30–40 mg/kg Tomato Spirit Water to keep the stigma moist and increase fruit setting. Prune excess flowers, leaving 3–4 fruits per cluster on the first and second trusses, and remove dense or peripheral blooms to optimize fruit quality. 6. **Harvesting**: Begin harvesting in late August and complete by early September. **Third Crop: Autumn and Winter Celery** 1. **Variety Selection**: Choose "Ventura Celery," known for its strong growth and good yield. 2. **Sowing and Planting**: Sow seeds in mid-July, transplant seedlings in mid-September using flat cultivation methods. 3. **Soil Preparation and Fertilization**: Apply 5,000–8,000 kg of organic fertilizer, 20 g of diammonium phosphate or 100 g of superphosphate, and 20 g of urea per acre. Plow the soil to a depth of 30 cm, create raised beds 1 m wide, and plant according to the greenhouse span. Two days before planting, spray the seedlings to prepare them for transplanting. 4. **Planting Time**: Transplant in mid-September. Carefully dig up the seedlings with a spade, shake off the soil, do not cut the roots or leaves, and remove any diseased or weak plants. Sort seedlings by size and plant them in 6 rows per meter, with 8 cm spacing between plants, totaling 50,000 seedlings per mu. Ensure the roots are planted just below the soil surface without burying the heart or leaves. 5. **Field Management**: Due to high temperatures and strong sunlight, water thoroughly after planting and add two more irrigations within two days to encourage new root growth and maintain soil moisture. Loosen the soil promptly after rain or irrigation to promote root development and prevent leggy growth. 6. **Harvesting**: Harvest celery from mid-November to the end of January. Sell in batches as needed. Timely harvesting is crucial—harvesting too early reduces yield, while delaying harvest causes the petioles to become hollow and lose quality. Therefore, it's important to harvest at the right time to ensure optimal texture and market value.
