Greenhouse Tomato Cultivation Techniques
Growing tomatoes in a greenhouse is a great way for farmers to increase their income, and effective management during the growth period is crucial for achieving high yields and efficiency. Proper care ensures healthy plants, better fruit quality, and higher profitability.
1. **Optimize Reproductive Management**
This includes regular weeding, soil loosening, vine training, pruning, and removing old leaves to improve air circulation and light penetration. It also involves strict control of pests and diseases. Common tomato diseases include viral infections, bacterial wilt, early blight, and late blight. Insect pests such as aphids and bollworms can cause significant damage. Prevention is key—use disease-resistant varieties, disinfect seeds, control aphid populations, and avoid overwatering. Temperature control is also essential: during the day, maintain a temperature around 25°C by gradually opening vents, and keep night temperatures between 10–13°C. As the afternoon cools down, reduce or close the vents slowly to prevent sudden temperature drops.
2. **Effective Fertilizer Management**
During summer and autumn, when rainfall is frequent, watering is usually not needed. However, when the second or third set of fruits begins to ripen and the soil feels dry, moderate watering is necessary. Apply top dressing based on plant growth to support fruit development, protect flowers, and enhance fruit quality. Using microbial fertilizers like Golden Baby Microbial Fertilizer as a base fertilizer can improve fruit color and sweetness. For additional nutrients, products like Gold Seedling Root Strength or Seedling Strong can be applied. Spraying Golden Baby Sweetening Spirit can enhance the appearance and taste of the fruit. If any greenhouse shows signs of nutrient deficiency, applying Jinbao Supplements can help restore plant vitality and promote growth.
3. **Timely Harvesting**
Tomatoes go through four stages of ripening: green, discoloration, mature, and fully ripe. For storage, harvest when they are still green. For transport, pick them when about one-third of the fruit turns red. For local sale or personal use, harvest when more than one-third of the fruit is red. Always handle the fruits gently, and avoid tearing the stem to prevent bruising during transport. Before the first frost, any unripe green fruits should be picked and stored in the greenhouse until they ripen. This extends the harvest season and increases profits. Avoid using hormones to speed up ripening, as this can affect fruit quality and consumer safety. Select and pack the fruits carefully to ensure the best results.
