Zhongyan 958 Tomato Cultivation Technology Zhongyan 958 is a new generation of indeterminate growth hybrid tomato developed by the Vegetable Research Group of the Chinese Academy of Sciences. Both parent lines were imported from Israel and have been carefully selected through extensive greenhouse trials. This variety is considered a promising successor to popular types like Golden Shed and Bull, offering significant improvements in growth potential, fruit size, and resistance to environmental stress. It addresses common issues such as weak growth, small fruits, deformed fruit during winter cultivation, and early aging. With four generations of breakthroughs in breeding, this variety marks a new era in tomato cultivation, setting a new standard for quality and performance. Key Features
1. **Strong Growth Potential**: Indeterminate type with up to 8–10 fruit clusters. Thick stems, well-developed roots, large leaves, and high photosynthetic efficiency.
2. **Superior Fruit Quality**: The fruit has excellent firmness, color, smoothness, and shape, outperforming many domestic varieties currently on the market.
3. **Climate Resilience**: High fruit set under both low and high temperatures, with minimal deformation or cracking. Fruits grow well, with small umbilical areas and no large flower buds.
4. **Good Commercial Value**: Uniform size, bright pink color, no green shoulders, smooth surface, and shallow grooves. The fruit weighs about 300g, with thick skin and long shelf life. Ideal for greenhouse and open field cultivation, as well as long-distance transport.
5. **Disease Resistance**: Strong resistance to leaf mold, tobacco mosaic virus (TMV), early and late blight, root-knot nematodes, gray mold, and other common diseases. Cultivation Tips
Compared to other varieties, Zhongyan 958 requires special attention in several aspects:
1. **Seedling Management**: If dwarf seedlings appear, remove them at planting. If already planted, prune and double-prune the side branches. Dwarf plants still produce large fruits, around 250g per cluster.
2. **Nursery Soil Preparation**: Use well-decomposed organic fertilizer, along with appropriate amounts of compound fertilizer and fungicide.
3. **Winter Seedlings**: Soak seeds until 30% germinate, then sow. Maintain moderate temperature and moisture to avoid excessive growth. Daytime temperature: 20–25°C, nighttime: 12–15°C. Avoid temperatures below 12°C at night.
4. **Strong Seedlings**: Sturdy stems, large leaves, and 7–8 leaves with large buds are ideal.
5. **Planting Density**: Due to vigorous growth, plant at 2,800–3,500 plants per acre depending on the season.
6. **Fertilization and Watering**: Apply base fertilizer with organic matter and balanced nutrients. Control water before fruit set and apply top-dressing when the first fruit reaches 50g. Use compound fertilizer with calcium, boron, and magnesium for better fruit development.
7. **Temperature Control**: Optimal daytime temperature: 20–25°C, nighttime: 12–15°C. During flowering and fruiting, maintain 25–28°C during the day and 15–17°C at night. Keep floor temperature between 17–20°C. Ventilate when temperatures exceed 32°C.
8. **Fruit Thinning**: Remove excess fruits to ensure uniform size. Leave 3–4 fruits per cluster after the first ear.
9. **Harvest Timing**: Harvest when fruits turn from white to red to prevent cracking due to moisture fluctuations. By following these guidelines, farmers can maximize yield and quality, making Zhongyan 958 a reliable and profitable choice for modern tomato farming. Its combination of strong growth, disease resistance, and superior fruit characteristics makes it an excellent option for both commercial and small-scale growers.
