The planting time of Chinese cabbage varies greatly by region and season. Now we introduce the efficient cultivation techniques of Chinese cabbage in autumn in the north. Seed and vegetable sales agencies in all counties and cities have sales.
First, choose a good variety
There are many varieties of Chinese cabbage, which can be divided into three basic ecological types: straight-barreled, raw-headed, and oval-shaped. However, because of the growing season, mid-late-maturing varieties that are disease-resistant, cold-resistant, high-yield, and shelf-resistant must be used for selection.
Second, sowing time
Under normal circumstances, it is appropriate to sow 3–5 days before and after the start of autumn, and the high temperature years can be postponed until mid-August. Disease-resistant, long-lasting late-maturing varieties can be properly sown early, and medium-maturing varieties with short growing periods can be properly sown several days later.
Third, preparations before sowing.
Chinese cabbage cannot be used continuously, and it cannot be rotated with other cruciferous vegetables. This is one of the important measures to prevent pests and diseases. 5 to 10 cm deep ditch, first water along the ditch, water penetration, the seeds evenly sprinkled in the ditch, and cover 0.8-1 cm thick fine soil, about 0.5 kg per acre seed amount, live cabbage After the shoots are unearthed, groundwater is used to keep the floor wet and reduce the surface temperature. In the absence of rain, watering is usually done on the day of sowing or the next day, so that the ridge surface is soaked. The second day of sowing is used to pour the second water and most of the sprouts are unearthed.
Removable Oxygen Generator
Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure.
With a cabinet for small capacity or container for big capacity, all the parts can be involved in, and removable with a vehicle.
