Colorful pepper
The growth of Capsicum annuum requires sufficient nutrition. The production of 1,000 kilograms of colorful pepper requires 4.2 kilograms of pure nitrogen, 1.1 kilograms of phosphorus pentoxide, and 6.5 kilograms of potassium oxide, and it also needs an appropriate amount of calcium fertilizer. Before planting, 4500 kg organic fertilizer per mu, 150 kg bio-organic compound fertilizer, 50 kg urea, 25 kg superphosphate, 50 kg potassium sulfate and 100 kg calcium fertilizer. When the seedlings are over and the first ear grows to the size of the walnut, the first topdressing is performed with 5 kg of pure nitrogen per acre and 6 kg of potassium oxide. When entering the first ear fruit (Jian pepper) is about to be harvested, the first layer fruit (for pepper) and the third layer of fruit continue to expand and the third layer of fruit is in the peak of the need fertilizer, should be reapplied the second time Top dressing, applying 6 kg of pure nitrogen per acre and 7-8 kg of potassium oxide. The third topdressing was performed about two weeks later and the amount of fertilizer was the same as the second. After 15 to 20 days, the fourth topdressing was performed with the same amount of fertilizer applied for the first time.
Dutch beans
During the seedling stage, nitrogen fertilizer was applied to supplement the phosphorus and potassium fertilizers during the growth period, and molybdenum and manganese fertilizers were added. The production of 1,000 kg of Dutch beans requires 2.4 kg of pure nitrogen, 0.8 kg of phosphorus pentoxide and 5.7 kg of potassium oxide. Before planting, 2500 kg of organic fertilizer, 100 kg of bio-organic compound fertilizer, 20 kg of urea, 25 to 30 kg of superphosphate, 40 kg of potassium sulfate and 0.5 to 1 kg of manganese sulfate were applied per acre before sowing. Into the extension of the cranberry period, the first topdressing, applied 3 kg of pure nitrogen per acre, potassium oxide 4 to 6 kg. During the flowering and poding stage, the second top dressing was applied, and 2~2.5 kg of pure nitrogen and 3.5 kg of potassium oxide were applied per acre. Spraying 0.02% to 0.05% ammonium molybdate during flowering.
Green cauliflower
In fertilizer nutrients, nitrogen and phosphorus are most needed in the whole growth period, especially in the bulbous expansion stage, and potassium fertilizer is required after flower bud differentiation. Among the trace elements, boron and molybdenum are most needed. The production of 1000 kilograms 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, 2500 kg of organic fertilizer was applied per mu, 100 kg of bioorganic compound fertilizer, 50 kg of urea, 20-25 kg of superphosphate and 30 kg of potassium sulfate. Into the rosette period, the first topdressing, applied 4 kg of pure nitrogen per mu, 6 kg of potassium oxide. The second time in the rosette was topdressing, 2.5 kg of pure nitrogen and 4 kg of potassium oxide were applied per 6 mu. In the early stage of flower bulb formation, 0.2~0.5% borax can be sprayed out of the root.
