The packaged vegetables include Chinese cabbage, cabbage, lettuce, broccoli, etc. The common feature is that the organs for feeding are mainly vegetative. These vegetables are shallow-rooted vegetables, and the roots are shallow and should be fertilized in shallow layers. The ratio of the three elements of NPK is about 1:0.4:1.1-1.3, the fertilizer is mainly organic fertilizer, supplemented by chemical fertilizer; the base fertilizer is the main, and the top dressing is supplemented.
1. The root system of Chinese cabbage is developed, and the planting requires the selection of deep, loose, fertile sandy loam or light clay loam. Chinese cabbage should be applied to the four fertilizers throughout the growth period. First, the base fertilizer is applied. Generally, no more than 3,000 kilograms of decomposed organic fertilizer is applied per mu. Bio-organic fertilizer should be applied in combination with organic fertilizer, and the dosage of 80-100 kg per mu. The second is to plant and apply the seedling fertilizer. 2 kg of microbial inoculum and 5 kg of ammonium sulfate were applied to the seeding point, the ditch and the soil were thoroughly mixed before the live broadcast, and then watered for sowing. The third is to supplement the application of the fertilizer at the beginning of the group. When there are a few plants in the field to start the group, the manure is 800-1500 kg, and the black plus white bio-fertilizer is 10-15 kg. Fertilizer is applied to the small ditch 8-10 cm on the edge of the plant and the soil is covered. The fourth is to chase the ball before the heart. Generally, 15 kg of urea is applied to the deep ditch, and 10 kg of superphosphate and potassium sulfate are used.
2, cabbage is easy to plant, choose soil fertile, convenient irrigation and drainage, not heavy land. 2 kg of bio-organic fertilizer was applied per square meter of seedbed, and the bio-organic fertilizer and the seedbed soil were evenly mixed, and the seedlings were seeded finely. Seedling age 30 days, seedlings 4-6 leaves can be colonized. Before the planting, the application of bio-organic fertilizer is 80-100 kg, and the organic fertilizer is 4000 kg. When planting, it can be transplanted with 2 kg of microbial inoculum after planting or planted after rooting. After planting the seedlings, watering, slowing down the seedlings, applying urea 5-10 kg, and applying the fertilizer 2 times before and after the lotus sitting period, combined with watering and applying black plus white biological fertilizer 15-20 kg. After the ball is finished, stop the management of fertilizer and water.
3, lettuce is also known as leaf lettuce, the root system is shallow, the roots are developed, and the root group is mainly distributed in the soil layer of 20-30 cm on the surface. Before sowing, apply 2 kg of bio-organic fertilizer per square meter, mix it with the seedbed soil and plant it. Before planting, fertilize the soil first, apply 60-80 kg of bio-organic fertilizer per mu, and then make a sorghum 1 m wide, which is 10-15 cm high. When planting, it can be transplanted with 2 kg of microbial inoculum after planting or planted after rooting. After transplanting the seedlings, you can topdress and water the plants. After 5-7 days of lettuce seedlings, 20 kg of bio-organic fertilizer is chased, and the soil is moistened with water. At the beginning of the heart leaf involution, the leaves were sprayed with 0.2% urea and 0.2% potassium dihydrogen phosphate solution.
4. The growth cycle of broccoli can be divided into five stages: germination stage, seedling stage, lotus sitting stage, flower bulb maturity stage and convulsion flowering result period. Cauliflower has a shallow root distribution and requires a large amount of fertilizer. It must be fertile, loose, rich in organic matter, loam or clay loam with good fertilizer and water retention properties, and must be applied to the base fertilizer. In the cultivation process of broccoli, we must first pay attention to the application ratio of nitrogen, phosphorus and potassium in the nutrient soil during the nursery period. Before the planting, the application of bio-organic fertilizer 80-100 kg and organic fertilizer 2500-5000 kg as the base fertilizer. Lotus leaf growth and flower bud development stage, with 8-8 kg of ammonium sulfate. During the ball-forming period, generally use about 15 kg of ammonium sulfate for irrigation, and apply fertilizer once every 8-10 days until the flower ball is fully grown.
