The fertilization method of celery: the production of 1000 kg of celery requires 2 kg of pure nitrogen, 1 kg of phosphorus pentoxide, and 4 kg of potassium chloride. Before planting, 5,000 kg of high-quality farmyard manure and 40 kg of phosphate fertilizer were applied. When the celery plant height is 10 cm, the first topdressing is started. The cultivating nitrogen fertilizer is 7-10 kg and the potassium fertilizer is 10-15 kg. Celery enters a prosperous growth period, chasing fat every 7 to 10 days, even chasing 3 to 4 times, applying 15-20 kg of nitrogen fertilizer per acre, 10-20 kg of phosphate fertilizer, and 20-25 kg of potassium fertilizer. Each top dressing should be combined with watering.
Fertilization method of pepper: The production of 1000 kg of pepper requires 5.2 kg of pure nitrogen, 1.2 kg of phosphorus pentoxide, and 6.5 kg of potassium chloride. Before planting, 5,000 kg of high-quality farmyard manure and 50 kg of phosphate fertilizer were used as base fertilizer. The pepper is inflated at the beginning of the expansion to promote fruit enlargement. After each fruit picking, combined with soil and watering for topdressing, the application of pure nitrogen 15-18 kg, phosphate fertilizer 18-20 kg, potassium fertilizer 15-17 kg.
Spinach fertilization method: The production of 1000 kg of spinach requires 1.6 kg of pure nitrogen, 0.83 kg of phosphorus pentoxide, and 1.8 kg of potassium oxide. Before sowing, 5,000 kg of high-quality organic fertilizer and 40 kg of phosphate fertilizer were used as base fertilizer. Before wintering, when the spinach seedlings are about 10 cm high, according to the growth situation, the wintering fertilizer should be applied once, and 10 to 15 kg of nitrogen fertilizer and 10 to 15 kg of phosphate fertilizer should be applied. Be sure to pour frozen water one time before wintering to prevent dead seedlings in winter. In the spring of the next year, the fertilizer should be applied in time. The nitrogen fertilizer should be applied 20-20 kg, the phosphorus and potassium fertilizers should be 15-20 kg each, and the third fat should be chased every 10-20 days. Spinach topdressing should not spread the fertilizer in the heart leaves, so as not to cause burning seedlings, each time the topdressing should be combined with watering. Foliar application can also be carried out with 0.3% foliar fertilizer.
