During the cultivation season, green broccoli can be cultivated in spring and autumn. Spring cultivation is more than Yangshuo nursery in the middle and late January. It is 50 to 60 days for the seedling period, planting in the middle and late March, harvesting in the middle and late May, and planting seedlings in the autumn and mid-July in the autumn and planting in the middle and early August. Mid-to-late harvest.
Soil preparation, fertilization and planting Green cauliflower grows strong, requires large amounts of fertilizer, must be combined with site preparation to apply base fertilizer; general Mushi quality circle fertilizer 5000 kilograms, decomposed manure dry 500 to 1000 kilograms, superphosphate 30 to 40 kilograms, plant ash 50 kilograms . After applying basal fertiliser, plough deep and plow it, and then level it down to make it 1.3 to 1.5 meters wide. When the green cauliflower seedlings grow to 5 to 6 true leaves, they are planted. Generally, each row is planted with 2 rows and the plant spacing is 30 to 40 cm. The planting density is about 2500 plants per mu; the early-maturing varieties can be planted densely to about 3,000 plants per mu. .
Fertilizer management Green cauliflower like fertilizer, timely fertilizer and watering in phases is the key to good quality and high yield. The type of topdressing fertilizer is mainly nitrogen fertilizer, and it enters into the formation period of flower bulbs. Phosphorus and potassium fertilizers are added appropriately to promote the rapid growth of flower bulbs. The florets and corms of broccoli flowers are harvested several times and harvested in time after each harvest. To promote lateral flower bulb growth. The cauliflower needs a large amount of water, and it should be watered in a timely manner during the rosette stage and the formation of the flower bulb to keep the soil moist. In rainy areas or seasons, the drainage should be promptly prevented to prevent water from picking up roots.
The harvested green cauliflower at the top of the plant is fully swollen and harvested when the buds are not yet open; harvesting late can easily lead to scatter and flowering. When harvesting, cut off the flower bulb with a flower stem about 10 cm below. After the bulb was harvested, the axillary buds of the plants germinated, and the lateral branches quickly emerged. The flower buds were formed on the top of the lateral branches, that is, the lateral flower bulbs. When the lateral flower bulbs grew to a certain size and the buds were not yet open, they could be harvested again. . In this way, it can generally be harvested continuously 2 to 3 times.
The medical compressed air plant consists of the air compressor, general filter, aftercooler, precision filter, desiccant air dryer, air buffer tank, activated carbon filter, compressed air quality monitor, decompressor, valve, pipeline and terminal. The system generates compressed air through an air compressor, removes the impurities, oil mist and moisture in the compressed air through an adsorption dryer filter unit, delivers the air to the air storage tank and supplies it through a pipeline to the terminal equipment in the operating room, ICU and other inpatient wards after decompression.
