Scallion colonization should pay attention to problems

Scallion colonization is generally planted in the middle and late June after wheat harvest. During the planting period, 5000-6000 kg of decomposed organic fertilizer is applied per acre. In combination with ploughing, the soil fertilizer is fully mixed with a row spacing of 70-80 cm and a spacing of 5-6 cm. The depth of the ditch is 25-30 cm.

If the seedlings are graded and ready for transplanting before transplanting, if the seedling shoots are too dry, they should be poured with water once in advance to facilitate seedling raising. When raising seedlings, remove diseased seedlings, weak seedlings, residual seedlings, large seedlings should be slightly thin, seedlings slightly dense, onion seedlings avoid long stacking or exposure, should be placed in the shade.

Put onions, put onion before the soil treatment should be done, with 10% phytochemical plus 70% thiophanate-methyl 2 bags per acre, evenly thrown into the soil, to prevent the underground tigers and other pests harm. In front of the ditch, dig a large ditch with shallow ditch and put green scallions on one side. Press 5 to 6 cm of plant spacing. Place the green onions close to the ditch. Drain the scallions into a planed shallow ditch. Try to keep the onion stalks upright and cover the roots. Fine soil 5 to 6 cm, gently step on. Immediately after slipping, the amount of water should be small to prevent the onion from being washed down. General acres planted 18000 ~ 23000 strains, large seedlings appropriate sparse planting, seedlings suitable close planting.

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.
