The drought continued, experts warned: As the seedlings resist drought and promote seedling growth

At present, droughts of varying degrees have occurred throughout the province and have been increasing. Among them, drought conditions in some areas of Huaibei and Jianghuai are serious, affecting the emergence and growth of wheat. According to the medium-term weather forecast released by the Central Meteorological Observatory on November 29, the meteorological drought in Huanghuai and other places will continue to develop in the next 10 days.

Researcher Ma Hongxiang, the director of the national wheat industry technical system at the Suzhong Experimental Station, reminded that at present, the management of wheat fields with drought as the center must be well managed. Wheat seeds along many fields in Nanmai District of Jiangsu Province are in the germination stage and have not even germinated yet. Water should be applied to these fields as soon as possible to promote seedling emergence. If the ground water level in the field is high for rice and wheat fields with high soil viscous weight, horse water can be fed and rapid irrigation can be conducted to avoid bad seeds caused by long time in the field. The wheat seedlings were watered along Huai Mai District and Huaibei District. For poorly emerged wheat fields, watering should be done as soon as possible. For late-seeding wheat fields with poor moisture and seedling difficulties, we must pay close attention to pouring the headwaters. The emerging field should also be filled with water as soon as possible to promote root growth and tillering. .

According to Ma Hongxiang, it is easy for drought to cause the emergence of wheat seedlings. After the emergence of wheat, it must be checked universally. For the poor quality of the sowing, the seedlings must be soaked with the same variety of wheat seeds, and the seeds should be replanted soon after germination. Wheat seedlings have 2 to 3 leaves, small groups, weak seedlings, or wheat fields where the leaves are clearly yellow, can be combined with 5 kg of watered urea per acre. Large amount of straw returned, poor quality of soil preparation, or fields that have not been repressed after sowing and cultivating, and the soil in the cultivating layer is suspended. The wheat fields planted prematurely, with large sowing rates, large groups, and overgrown plants should also take repressive measures to control their growth and protect their seedlings for safe wintering.

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.
