Celery is the edible vegetable for the petiole, and if the cultivation and management are not fine, the fiber will increase and the food value will be lost. The use of softening cultivation of celery can reduce the content of cellulose, decompose the chlorophyll in the petiole, and form lutein, thereby increasing the value of food and increasing yield. Softening cultivation methods are:
Soil softening method Pile softening requirements celery spacing 33 to 40 cm. When the seedling height is 35-50 cm, apply a heavy fertilizer first and then pour it three times. After 5 to 7 days, use a straw to bind the bases of each cluster of plants and loosen the soil once to make the soil a little dry. Then, bury the soil on both sides of the plants and tap the soil to make the soil surface smooth. The first time the earth is about 4 cm thick, and once every 2 to 3 days, it will be earthed once again. This way, the earth will be continuously cultivated for 5-6 times, and the height will be about 20-25 cm. The leaves of the plants will be exposed and the buds will not be damaged. The time for earth-cultivation is preferably on sunny days and the soil is not wet in the afternoon. It will be harvested after about 30 days.
The softening of the hoarding softening panels also requires that the celery spacing be 33 to 40 cm. When the height of the seedlings is about 35 cm, the plants are first raised and erected upwards to expose the soil between the rows. Then use 1.7-3.5 meters long, 13- 17 centimeters wide, 2 to 3 centimeters thick wood or plastic board, etc., on both sides of the celery plant, the two ends of the board are fixed with wooden stakes. In the middle of the two plates, the soil is 13 to 17 cm thick, so that the plants are free from trauma. The soil does not fall into the heart of the cabbage to prevent the plants from rotting. Precocious celery only need to cultivate soil 1 or 2 times, about 30 days after harvest.
The bamboo raft softening method spacing and height requirements are the same as above. With slender bamboo poles, the plant petioles were clamped along the planting line. Both ends of the bamboo were tied with grass or nylon ropes, and then soil was subdivided according to the soil softening method. Usually about 30 days can be harvested.
The natural softening method is a soft, half-shadow planting. In the autumn, celery is planted in 7 cm 7 cm lines and rows, each 3-4 lines. About 20 to 28 centimeters around the edge of the soil, with straw or reeds, thatched grass made around the perimeter. Before plant closure, cultivating 2 or 3 times, combined with cultivating nitrogen fertilizer 3-5 times, to promote plant tillering, leaf growth and flourishing, covering the top seal line as soon as possible, so that the petiole grows in a dark environment, to achieve petiole softening purposes .
The urine bag set consists of A drainage bag and A suction device. Qhy-a is the single drainage bag, and qhy-b is the drainage bag + suction device. The drainage bag consists of the bag body, Catheter , lifting lug, joint, guard cap, drainage port, drainage bottom plug, anti-reflux device, and current limiting clip.The suction device is composed of negative pressure bottle, drainage tube joint, suction tube joint, suction connection pipe, automatic drainage device, drainage port and bag body.Should be sterile.
It is used for the collection of body fluids (blood, gastric juice, etc.), secretions (sputum, flushing fluid, etc.) and human excreta (urine, etc.) in hospital, clinical departments and during surgery or after surgery.
