1. cucumber. Cucumber is a kind of high-yield vegetable. It has a long period of time, and it needs long-term nutrition to meet the needs of growth and development. The production of 1000 kg of cucumber requires 2.6 kg of pure nitrogen, 1.5 kg of phosphorus pentoxide, and 3.5 kg of potassium oxide. Before the cucumber is planted, the high-quality organic fertilizer is 5,000 kg--7500 kg, and the phosphate fertilizer is 25 kg--30 kg. When the cucumber enters the early stage of the melon, the first top dressing is carried out. The mu fertilizer is applied with 10 kg--15 kg of nitrogen fertilizer and 15 kg--20 kg of phosphorus and potassium fertilizer. Afterwards, the fertilizer is chased once every 7 days to -10 days, and combined with watering. The whole cucumber was topdressed 8 times -10 times during the growth period. Foliar spray can also be carried out according to the concentration of 0.3% chemical fertilizer and the growth hormones such as pesticide or spray Shibao, Zengjialing and Fengguo.
2. tomato. The production of 1000 kilograms of tomatoes requires 3.85 kilograms of pure nitrogen, 1.2 kilograms of phosphorus pentoxide, and 4.4 kilograms of potassium chloride. According to the calculation of 5000 kilograms per mu, 5,000 kilograms of high-quality farmyard manure and 50 kilograms of phosphate fertilizer are applied before the planting. When the first ear is expanded to the size of egg yolk, the first top dressing should be carried out, and the application of pure nitrogen 18 kg - 20 kg, phosphate fertilizer 15 kg - 16 kg, potassium fertilizer 16 kg - -17 kg, second, third, When the four spikes are swollen to the size of the egg yolk, the fertilizer should be topdressed in time. In this case, the amount of fertilizer needs to be large, and the amount of topdressing should be increased appropriately. Each time you apply fertilizer, you should combine watering. It is also possible to use a 0.35% chemical fertilizer combined with a disease-preventing drug for foliar application, or a mixture of sitting fruit and fruit.
3. Chili. The production of 1000 kg 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 first top dressing is started at the beginning of the pepper expansion to promote fruit enlargement. The application of pure nitrogen is 15 kg--18 kg, phosphate fertilizer 18 kg--20 kg, and potassium fertilizer 15 kg--17 kg. The amount of fertilizer needed for the second layer of fruit, the third layer of fruit, the fourth layer of fruit, and the star of the sky increased gradually, and the amount of topdressing should be increased appropriately to meet the nutrients required for the vigorous period. Each time the top dressing should be combined with soil and watering. Foliar spray can also be carried out by mixing 0.3% of Fengguo and Capsicum.
4. celery. The production of 1000 kg of celery requires 2 kg of nitrogen, 1 kg of phosphorus pentoxide, and 4 kg of potassium chloride. Before planting, the application of high-quality farmyard manure 5000 kg and phosphate fertilizer 40 kg. When the height is 10 cm, the first top dressing is started, and the nitrogen fertilizer is 7 kg -10 kg and the potassium fertilizer is 10 kg - 15 kg. Celery enters the vigorous growth period, chasing fertilizer once every 7 days -10 days, a total of 3 times -4 times, 15 kg - 20 kg per mu, 10 kg - 20 kg of phosphate, 20 fertilizers Kilogram - 25 kg. Each time the top dressing should be combined with watering. It can also be combined with disease prevention with 0.3% concentration of spray Shibao for foliar application.
5. spinach. Spinach needs to be dormant for a long time in winter, so pay attention to fertilization. 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 planting, 5,000 kg of high-quality organic fertilizer and 40 kg of phosphate fertilizer were applied. Adequate base fertilizer and strong seedling growth are the key to safe wintering of vegetables. Before wintering, the spinach seedlings are about 10 cm high. According to the growth situation, the wintering fertilizer should be applied once, and 10 kg--15 kg of nitrogen fertilizer and 10 kg of phosphate fertilizer should be applied. -15 kg. 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 with 20 kg -25 kg, phosphorus and potassium fertilizer 15 kg - 20 kg, and the third fat is chased every 10 days - 15 days. Spinach top dressing should not spread the fertilizer in the heart leaves, so as not to cause burning seedlings, each time the top dressing should be combined with watering. Foliar application can also be carried out with 0.3% foliar fertilizer. The fertilization techniques of spring spinach and autumn spinach are basically the same as winter spinach.
2. tomato. The production of 1000 kilograms of tomatoes requires 3.85 kilograms of pure nitrogen, 1.2 kilograms of phosphorus pentoxide, and 4.4 kilograms of potassium chloride.
