How to make reasonable fertilization for greenhouse cucumber and tomato
1. When fertilizing cucumbers and tomatoes at different growth stages, it's important to adjust the fertilizer amount and concentration accordingly. During the seedling stage, nutrient absorption should be maintained without over-fertilizing—use small amounts with low concentration. In contrast, during the fruiting stage, more fertilizer is needed, and the concentration can be higher. Some farmers mistakenly apply 200 kg of diammonium phosphate at once, which is not a scientific approach to achieve high yields. Relying solely on one type of fertilizer can lead to imbalances and poor results. 2. Fertilization should also be adjusted based on soil conditions. When applying top dressing through irrigation, the amount of fertilizer should match the soil's characteristics. If the soil is dry, use a lower concentration; if it's moist, you can increase the concentration but reduce the quantity. Sandy soils have poor water retention and fertility, so they require frequent but small applications. On the other hand, clay soils hold moisture well and have better fertility, so less frequent but larger doses are more effective. 3. Weather changes also play a key role in fertilization. High temperatures can reduce the root system’s tolerance to fertilizer concentration, so it’s better to use a diluted solution to avoid root burn. Conversely, when temperatures are low, the concentration can be increased slightly. Always adjust your fertilization strategy according to the weather conditions to ensure optimal plant health and growth. 4. Different types of fertilizers require different application methods. For chemical fertilizers, using furrows helps concentrate nutrients and improve efficiency. After topdressing, cover the soil promptly to prevent nutrient loss due to evaporation. When applying nitrogen-based fertilizers, keep them at least 10 cm away from the plant roots to avoid damage. Combining compost with irrigation can significantly enhance fertilizer effectiveness and promote better nutrient uptake. In general, the base fertilizer for cucumbers and tomatoes is similar. For one mu (approximately 667 square meters) of greenhouse land, you can use about 3,000 to 4,000 kg of well-decomposed manure or 520 to 640 kg of avermectin organic fertilizer. Note that chicken manure is no longer used in this type of organic fertilizer, and 40 to 50 kg of avermectin organic fertilizer can replace 500 to 800 kg of chicken manure. Additionally, include 40 kg of diammonium phosphate, 100 kg of potassium sulfate, 30 kg of urea, 4 kg of calcium nitrate, 3 kg of borax, 1.5 kg of zinc sulfate, and 40 kg of microbial agents. Spread these fertilizers deep into the soil. Microbial agents can be applied by trenching or injecting directly into the planting area. Based on our recent experiments in Shouguang and Liaocheng, using a balanced fertilizer formula can not only save costs but also significantly increase the yield of both cucumbers and tomatoes.
