1. Green cauliflower is in fertilizer nutrients. During the whole growth period, nitrogen and phosphorus are most needed in the flower expansion period, and potassium fertilizer is needed after flower bud differentiation. Among the trace elements, boron and molybdenum are most needed. The production of 1000 kg of green cauliflower requires 2.5 kg of pure nitrogen, 1.1 kg of phosphorus pentoxide, and 2.9 kg of potassium oxide. Before planting, apply 2,500 kg of organic fertilizer per mu, 100 kg of bio-organic compound fertilizer, 50 kg of urea, 20 to 25 kg of superphosphate, and 30 kg of potassium sulfate.

In the late stage of the rosette, the second top dressing was applied, and 2.5 kg of pure nitrogen and 4 kg of potassium oxide were applied per 6 mu. At the beginning of flower bulb formation, 0.2 to 0.5% borax can be sprayed outside.
2, cherry tomatoes in addition to nitrogen, phosphorus, potassium fertilizer, pay attention to increase the application of calcium, boron fertilizer. The production of 1000 kg of cherry tomatoes requires 3.85 kg of pure nitrogen, 1.15 kg of phosphorus pentoxide, and 4.44 kg of potassium oxide. Before planting, apply 5000 kg of organic fertilizer per mu, 200 kg of bio-organic compound fertilizer, 50 kg of urea, 30-50 kg of superphosphate, 40 kg of potassium sulfate, 100 kg of calcium fertilizer and 1.5 kg of borax. Generally, when the first ear fruit begins to expand, the first top dressing can be carried out, and 5 kg of pure nitrogen and 6 kg of potassium oxide per acre are applied. The second top dressing is to harvest the first ear of fruit, and when the second ear is swollen, apply 5 kg of pure nitrogen per acre and 6 to 7 kg of potassium oxide. The third top dressing is about to be harvested in the second ear, and when the third ear is swollen, 4 kg of pure nitrogen per acre and 5 to 6 kg of potassium oxide are applied.
3, colorful peppers and colorful peppers need sufficient nutrient conditions, the production of 1000 kg of colorful peppers requires 4.2 kg of pure nitrogen, 1.5 kg of phosphorus pentoxide, 6.5 kg of potassium oxide, and also need the right amount of calcium fertilizer. Before planting, apply 4,500 kg of organic fertilizer per mu, 150 kg of bio-organic compound fertilizer, 50 kg of urea, 25 kg of superphosphate, 50 kg of potassium sulfate, and 100 kg of calcium fertilizer. When the seedlings are over and the first ear is grown to the size of the walnut, the first top dressing is carried out, applying 5 kg of pure nitrogen per acre and 6 kg of potassium oxide. When entering the first ear fruit (men pepper) is about to be harvested, the second layer of fruit (for pepper) and the third layer of fruit continue to expand and the third layer of fruit is falling and fruit set, for the peak of fertilizer demand, should be reapplied 2 The second top dressing, applying 6 kg of pure nitrogen per mu and 7-8 kg of potassium oxide. The third top dressing was carried out about half a month later, and the amount of fertilizer applied was the same as the second time. After 15 to 20 days, the fourth top dressing was carried out, and the amount of fertilizer applied was the same as the first time.
4, thorn-free cucumber, thorn-free cucumber, hi-fertilizer, while applying organic fertilizer, with the application of NPK fertilizer. The addition of molybdenum fertilizer can increase the vitamin content of the fruit and reduce the nitrate and nitrite content. The production of 1000 kg of thorn-free cucumber requires 2.6 kg of pure nitrogen, 1.4 kg of phosphorus pentoxide, and 3.5 kg of potassium oxide. Among them, the amount of fertilizer required for the period accounts for more than 80% of the total fertilizer requirement. Before planting, apply 5,000 kg of organic fertilizer per acre, 250 kg of bio-organic compound fertilizer, 60 kg of urea, 30-40 kg of superphosphate, and 50 kg of potassium sulfate. The first top dressing was carried out at the beginning of the melon, and the pure nitrogen was applied 3 to 4 kg per mu and the potassium oxide was 4 to 6 kg. In the early stage of the melon, the second topdressing was carried out, and 3 to 4 kg of pure nitrogen per acre and 5 to 6 kg of potassium oxide were applied. In the middle of the melon, the third top dressing is carried out, and each of the acres is applied with 3 to 4 kg of pure nitrogen and 5 to 6 kg of potassium oxide. Spray 0.02-0.05% ammonium molybdate during the fruiting period.
5, the Netherlands bean seedlings supplemented with nitrogen fertilizer, the application of phosphorus and potassium fertilizer in the prosperous period, pay attention to the application of molybdenum fertilizer and manganese fertilizer. The production of 1000 kg of peas requires 2.4 kg of pure nitrogen, 0.8 kg of phosphorus pentoxide and 5.7 kg of potassium oxide. Before planting, apply 2500 kg of organic fertilizer per mu, 100 kg of bio-organic compound fertilizer, 20 kg of urea, 25-30 kg of superphosphate, 40 kg of potassium sulfate, and 0.5-1 kg of manganese sulfate. Into the extension of the vines, the first top dressing, 3 kg of pure nitrogen per mu, 4 to 6 kg of potassium oxide. In the flowering and pod-forming stage, the second top dressing was carried out, applying 2 to 2.5 kg of pure nitrogen per acre and 3.5 kg of potassium oxide. Spraying 0.02-0.05% ammonium molybdate at the flowering stage.
6. In addition to nitrogen, phosphorus and potassium in American celery, the demand for boron in celery is relatively large. Adding zinc fertilizer can reduce the content of nitrate and nitrite in fresh vegetables. The production of 1000 kg of celery requires 2.0 kg of pure nitrogen, 0.93 kg of phosphorus pentoxide, and 3.9 kg of potassium oxide. Before planting, apply 4000~5000 kg of organic fertilizer per acre, 150 kg of bio-organic compound fertilizer, 40 kg of urea, 25-35 kg of superphosphate, 40 kg of potassium sulfate, and 1~1.5 kg of zinc sulfate. The plant enters the vigorous growth period and carries out the first top dressing. The application of pure nitrogen is 3 kg per mu and the potassium oxide is 5-6 kg. After half a month into the second top dressing, apply 2 to 2.5 kg of pure nitrogen per mu and 4 to 5 kg of potassium oxide. In the vigorous growth period, 0.2 to 0.5% borax can be sprayed outside.
