The broccoli broccoli needs nitrogen and phosphorus fertilizers most during the expansion of the flower bulbs. Potassium fertilizer is required after flower bud differentiation. Among trace elements, boron and molybdenum are most needed. The production of 1,000 kilograms of broccoli requires 2.5 kg of pure nitrogen, 1.1 kg of phosphorus pentoxide, and 2.9 kg of potassium oxide. Before planting, 2500 kg of organic fertilizer, 100 kg of bio-organic compound fertilizer, 50 kg of urea, 20-25 kg of superphosphate and 30 kg of potassium sulfate were applied per acre. Into the rosette period, the first topdressing, applying 4 kg of pure nitrogen per mu, 6 kg of potassium oxide. The second time the rosette was top dressing, 2.5 kg of pure nitrogen and 4 kg of potassium oxide were applied per acre. In the initial stage of bulb formation, 0.2% to 0.5% borax solution can be sprayed out of roots.
Cherry tomatoes in addition to nitrogen, phosphorus and potassium, but also pay attention to increase calcium, boron fertilizer. The production of 1,000 kilograms of cherry tomatoes requires 3.85 kilograms of pure nitrogen, 1.15 kilograms of phosphorus pentoxide, and 4.44 kilograms of potassium oxide. Before planting, 5000 kg of organic fertilizer, 200 kg of biological organic 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 were applied per acre. Generally when the first fruit begins to swell, it can be topdressed for the first time, with 5 kg of pure nitrogen and 6 kg of potassium oxide per acre. The second time dressing is the first time the fruit is about to be harvested. When the second fruit is enlarged, 5 kg of pure nitrogen and 6 to 7 kg of potassium oxide are applied per mu. The third time dressing fertilizer is about to be harvested in the second ear, and when the third ear is enlarged, 4 kg of pure nitrogen and 5 to 6 kg of potassium oxide are applied per mu.
The production of 1,000 kilograms of colorful peppers for colorful peppers requires 4.2 kg of pure nitrogen, 1.1 kg of phosphorus pentoxide, and 6.5 kg of potassium oxide. It also requires adequate amounts of calcium fertilizer. Before planting, 4500 kg of organic fertilizer, 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 were applied per mu. When the seedlings are over and the first ear grows to the size of the walnut, the first topdressing is carried out with 5 kg of pure nitrogen and 6 kg of potassium oxide per acre. When the first fruit is about to be harvested, the second layer of fruit and the third layer of fruit continue to expand, and the third layer of fruit is falling and setting fruit, it is the peak of fertilizer application. The second fertilizer should be reapplied, and pure nitrogen is applied per acre. 6 Kg, potassium oxide 7 to 8 kg. The third round of topdressing was performed about two weeks later and the amount of fertilizer applied was the same for the second time. After 20 days, the fourth topdressing was performed with the same amount of fertilizer applied for the first time.
