High-yield and High-quality New Maize Variety

"Three North No.6" is a new type of late-mature and large ear corn with good early-onset, drought-resistant early stage, late-tolerance and low-temperature tolerance, and comprehensive resistance. The variety has the advantages of high yield and stable yield, high yield potential, wide suitable area, high quality, mature live stalks, and dual use of grain and feed. Since its approval, the area has been promoted to more than 100 million mu. Experimental demonstrations in various regions have performed outstandingly with large scale promotion. Value and promotion prospects. The source of the variety "Sanbei VI" is a new corn variety cultivated by Sanbei Seed Industry Co., Ltd. in 1999. The variety has passed national examination and approval (certification number: Guo Juyu 2004012), which is one of the major new crop varieties introduced in our province this year (the introduction and approval number: Shaanxi Yinyu 2005012). The characteristic characteristics were 103 days in the summer sowing period in southern Shaanxi, which was comparable to the control Dandan 13. The spring corn area in northern Shaanxi is comparable to the control Nongda 108. The seedlings have purple sheaths, green leaves, and green leaves. The plant type is semi-compact, with a plant height of 277 cm, an ear position of 112 cm, and 21 adult plant leaves. Tassels developed, pollen volume large, yellow anthers, pale green shells, filaments green, ear tube type, ear length 20.2 cm, ear thickness 5.5 cm, ear rows 16-20 rows, red cob, orange-red seeds, grain The type is horse-shaped, closely arranged, deep, with a grain weight of 403 grams. Seedlings are resistant to low temperatures, strong seedlings, well-developed root systems, and lodging resistance. Two years of inoculation by Dandong Academy of Agricultural Sciences, Liaoning Province, resistance to large spot disease, gray spot disease, leaf spot disease, resistance to sheath blight, head smut, and corn borer. The quality test was determined by the Ministry of Agriculture's Cereal Quality Supervision, Inspection and Test Center (Beijing), with a bulk density of 726 g/L, a crude protein content of 8.77%, a crude fat content of 4.26%, a crude starch content of 73.25%, and a lysine content of 0.24%. According to the Ministry of Agriculture's Grain Quality Supervision, Inspection and Test Center (Harbin), the grain bulk density was 716 g/L, crude protein content was 9.92%, crude fat content was 4.94%, crude starch content was 70.86%, and lysine content was 0.28%. Yield performance Shaanxi Southern corn regional trial (Xiaoxing group) average yield 502.4 kg per mu, an increase of 5.6% over the control Dandan 13 production. In 2004, production was significantly increased in Yanan pilot station (spring broadcast) production test. Cultivation Techniques 1. About 3,000 plants per mu. 2, pay attention to the prevention and control of head smut, corn borer high-precision area, pay attention to the prevention and control of aphids during growth. 3. Apply 10-20 kg of ammonium diammonium phosphate to planting fertilizer, apply appropriate amount of potassium fertilizer or 20-30 kg of ternary compound fertilizer, and reapply nitrogen fertilizer once at the jointing stage. The fertility plots in the middle and top are planted to increase the yield. It is suitable for planting in the spring maize area in northern Shaanxi and the summer maize area in southern Shaanxi.

Sorfa syringe filters are disposable laboratory consumables for filtration of aqueous solutions in four types of membranes: PES, MCE, PVDF, PTEFand NYLON. Accordingly, four color housings mate with these membranes for easy identification. For pore diameter of membrane, two sizes are available of 0.22 um and 0.45 um. Housing diameter also is in two sizes of 15 mm and 30 mm.

Each Syringe Filter consists of a circular ring shell, a luer-lock connection with a piece of circular membrane inside. The net structure on luer lock connector is diversion groove which guide aqueous solutions to fill connector during the filtration process. This feature takes full advantage of membrane area for filtration of aqueous solutions. All Sorfa syringe filters are packaged in plastic boxes with sterilization, RNase-free, DNase-free and Non-pyrogenic.
