1. According to cucumber and tomato fertilization needs at different growth stages, tomato seedlings must ensure proper nutrient absorption, so fertilizers should be applied in small amounts with low concentration. During the fruiting stage, larger amounts of fertilizer are needed, and the concentration should be higher. However, some farmers mistakenly apply 200 kg of diammonium phosphate at once, which is not scientifically sound. Relying solely on diammonium phosphate to achieve high yields can lead to imbalanced nutrition and long-term soil degradation.
2. Fertilization should be adjusted based on soil conditions. When applying fertilizer through irrigation, the moisture level of the soil must be considered. If the soil is dry, use a lower concentration but apply more fertilizer. When the soil is moist, a higher concentration can be used with less quantity. Sandy soils have poor water and nutrient retention, so frequent but small applications are better. Clay soils retain water and nutrients well, so fertilization can be done less frequently but with larger quantities each time.
3. Adjust fertilization according to weather changes. Temperature affects the root's tolerance to fertilizer concentration. In high temperatures, it’s better to use lower concentrations to avoid root burn. In cooler conditions, higher concentrations can be used, as plants absorb nutrients more slowly. Therefore, fertilization practices should be flexible and responsive to changing weather conditions.
4. Different types of fertilizers require different application methods. For top-dressing, it’s best to apply fertilizer in trenches to concentrate its effect. After application, cover the soil promptly to prevent nutrient loss due to evaporation, which reduces efficiency. When applying nitrogen-based fertilizers, keep them at least 10 cm away from the plant roots to avoid root burn. Combining compost with irrigation can significantly improve fertilizer efficiency and promote healthy plant growth.
In general, the amount of base fertilizer for cucumbers and tomatoes is similar. For one mu (approximately 667 square meters) of greenhouse, about 3,000–4,000 kg of decomposed manure or 520–640 kg of avermectin organic fertilizer can be used. Note that if using organic fertilizer, chicken manure should no longer be applied. Typically, 40–50 kg of avermectin organic fertilizer can replace 500–800 kg of chicken manure, 40 kg of diammonium phosphate, 100 kg of pure potassium sulfate, 30 kg of urea, 4 kg of Indian calcium fertilizer, 3 kg of borax, 1.5 kg of zinc sulfate, and 40 kg of microbial agents. These materials should be deeply incorporated into the soil. Microbial agents can be applied through trenching or acupuncture, and they can also be concentrated during transplanting to enhance their effectiveness.
