The roots are well developed, the lodging resistance is good, the live stalks are mature, the stable yield is good, and the yield potential is high. Anti-dwarf mosaic disease, anti-blotch disease, tumor smut and other diseases. Cultivation points are reasonably densely planted: 3500-4000 strains per mu. It is suitable for cultivation of above-ground fertility plots; field management: less Miaomiao fertilizer, heavy panicle fertilizer, late flood prevention and drainage. During the seedling stage, attention was paid to the prevention and control of insect pests such as thrips and cotton bollworm, and attention was paid to the control of corn borers during the big bell mouth period. Appropriate areas are suitable for planting in the Huanghe, Huai, Haixia and Maize areas. Slide 9 Characteristic characteristics The variety summer breeding period 99 days. Compact plant type, 19 to 20 leaves, 258 cm plant height, 116 cm ear height; first leaf tip ovoid, fourth leaf margin green, leaf sheath sheath purple; middle branch number of male, male Sliver glume green, anther yellow, filament purple; ear tube, ear length 17.3 centimeters, ear 5.1 centimeters thick, ear rows 15.4 rows, number of rows 34.7 grains; cob white, yellow grain, half dentition, grain weight 329.4 Grams, the seeding rate was 90..2%. The cultivation points are suitable for a density of 4000 plants/mu. Use 50% thiram for wettable powder dressing to reduce the occurrence of tumor smut; pay attention to control of pests such as thrips and cotton bollworm at the seedling stage; use less fertilization at the seedling stage, re-fertilize at the big bell-mouth stage, and lose heart at the same time with phoxim particles. , prevent corn borer. Appropriate areas are suitable to promote planting in Henan. Jade Jade 12 Characteristics The seedling sheath of this species is light purple. The plant type is semi-compact, about 280 cm in plant height, about 115 cm in ear height, and 22 leaves of the whole plant. Tassels branching 10, anthers green, filaments light pink. The ear is long and cylindrical, with a white cob, generally about 25 cm in length, up to 30 cm in length, and about 18 rows per ear. The grain is yellow, horse-toothed, and the grain weight is about 400 grams. The rate of seed production is 87%. The spring sowing period is about 128 days, and the summer sowing period is about 98 days. Anti-head smut, high resistance to small spot, large spot, middle Curvularia spp., high resistance to stem rot, tumor smut, dwarf mosaic disease, and resistance to corn borer. Cultivation points Planting density 3000 to 3500 plants/mu. Suitable for high-water fertilizer planting, adopt phased fertilization method, less to raise seedling fertilizer, heavy panicle fertilizer. Pay attention to drought prevention and drainage at a later stage. During the seedling stage, attention was paid to the prevention and control of insect pests such as thrips and cotton bollworm, and attention was paid to the control of corn borers during the big bell mouth period. Appropriate areas are suitable for planting in spring sowing maize areas in Hebei province and similar corn ecological areas. Medical protective masks are masks made of one or more fabrics that have isolation effects on viral aerosols, virus-containing liquids, and so on. Under the respiratory airflow, it still has a barrier effect on viral aerosols, virus-containing liquids, etc., and when removed, the outer surface of the mask does not contact the human body, can filter particulates in the air, and block droplets, blood, body fluids, secretions, etc. . The use of medical masks includes adhesion testing, training, model selection, medical treatment and maintenance. Medical Protective Mask Protective Mask,Medical Protective Mask,Disposable Medical Protective Mask,Disposable Medical Protective Face Mask Guangzhou Aikangli Medical Technology Co., Ltd. , https://www.aikanli.com
Function and composition: The Medical Protective Mask consists of a mask face and a tightening belt. The mask face is divided into three layers: inner, middle and outer. The inner layer is ordinary sanitary gauze or non-woven fabric. Propylene fiber melt-blown material layer, the outer layer is non-woven fabric or ultra-thin polypropylene melt-blown material layer. This high-efficiency medical Protective Mask is highly hydrophobic and breathable, and has a significant filtering effect on tiny virus-carrying aerosols or harmful fine dust, and the overall filtering effect is good.
The medical protective mask has a good fit with the wearer's face, can filter particles in the air, block pollutants such as droplets, blood, body fluids, secretions, etc., and can filter non-oily particles by more than 95% Personal protective equipment commonly used to deal with airborne diseases.
Scope of application: Medical protective masks are better protective products. It is recommended to wear when there is serious environmental pollution or sudden medical infectious diseases (such as respiratory tract infectious diseases), to prevent the spread of viruses from patients or the environment to users.
Product specifications: According to the national standard GB 19083-2003 "Technical Requirements for Medical Protective Masks", important performances of medical protective masks include filtration efficiency, adhesion, liquid barrier performance, comfort, hygiene, and biological safety tests.
Important technical indicators: including non-oily particle filtration efficiency and airflow resistance.
(1) Filtration efficiency: Under the condition of air flow (85 ± 2) L / min, the filtration efficiency of aerodynamic median diameter (0.24 ± 0.06) μm sodium chloride aerosol is not less than 95%.
(2) Tightness: The overall fit factor of the mask should not be less than 100.
How to use: How to wear a head mask
(1) Gently pinch the nose clip and place the mask on the face to ensure that it can cover the nose and mouth.
(2) The upper elastic band is fastened on the head to prevent air from entering.
(3) Tighten the lower elastic band around the neck.
(4) Be sure to fully open the mask to minimize the number of layers used during breathing.
How to wear earhook masks
(1) Pass the ear straps with both hands, place the nose clip on the upper part, and wear the mask on the nose and mouth
(2) The ear strap should be placed at the base of the ear and spread from head to toe, so that the folds of the mask are fully unfolded, which helps to cover the face to the greatest extent and minimize the number of layers required for breathing.
(3) Gently pinch the nose clip to prevent air from entering.
