1. Timely Top-dressing Chinese Cabbage The use of leaf as a product is very sensitive to the requirements of nitrogen, phosphorus, and potassium. In production, it is necessary not only to apply base fertilizer, but also to top-dress according to different growth periods. During the growing season, most of the topdressing fertilizers are mainly available nitrogen fertilizers, such as ammonium sulfate, ammonium bicarbonate, ammonium phosphate, and urea. During the top-dressing period, it is necessary to master it. Generally, it is applied in four stages at the seedling stage, the rosette stage, the ball-initiating stage, and the mid-ballooning stage. The seedling period of 5 to 10 kilograms of ammonium sulfate per acre is applied. In the rosette stage, 1,000 to 1,250 kilograms of farmyard manure per acre, 15 kilograms of ammonium bicarbonate, or 10 kilograms of ammonium sulfate are applied. Ammonium sulphate 15 ~ 20 kg, the middle of the ball ball topdressing leech slurry 1000 ~ 1250 kg per acre, ammonium carbonate 10 ~ 15 kg or 1% of urea solution.
2. Diseases and Insects should be Treated by Both the Vegetable Farmers and the Three Major Diseases of Chinese Cabbage, but they often ignore the prevention and control of pests. In fact, the spread of many diseases has a close relationship with pests. Locusts are the main culprit in the spread of viral diseases, which can cause the Chinese cabbage to shrink and die. Soft-rot pathogens mainly infect insects, rain, and irrigation water, and dip Chinese cabbage from wounds. Pests cause wounds after damage, which is conducive to invading pathogens. Prevention and control of cabbage caterpillars, flea beetles and underground pests, and reduction of pest wounds can effectively reduce the occurrence of soft rot in Chinese cabbage. Therefore, the control of pests is also an important measure to prevent diseases.
3, bundling to postpone the binding can prevent the cabbage from suffering from frost, promote the strong heart, but also easy to harvest. However, the binding cannot be premature because the binding is too early and the photosynthetic efficiency of the outer leaves is greatly reduced, which hinders the normal growth of Chinese cabbage and is not conducive to the enrichment of leafballs. Usually 10 to 15 days before harvest, stop watering, lift the rosette leaves, hold the leaf ball, and then use soaked sweet potato pods or cereal grass to tie the leaves 3 to 5 centimeters from the top of the ball to make the core more secure. Solid and continue to grow.
Anesthesia ventilator disposable breathing bags are elastic and are available as disposable and reusable variants. Disposable bags, in comparison to reusable variants, are usually thinner and lighter, yet they provide reasonable durability. Generally, the reservoir bags are made of natural rubber (latex); however non-latex versions are also available for subjects with latex allergies. To improve the grip, they are usually textured. However, hourglass-shaped breathing bags are also available to allow better grip.
