Resistance to disease and high-yield beer malt --- Yangnong beer 2
I. Sources and types of varieties Yangnong Brewery No.2 (Su B9607) is a weak spring, early-maturing Erlang barley variety developed in 1997 by the Department of Agronomy, Yangnong Agricultural College. In November 2000, it passed the Jiangsu Provincial Variety Approval Committee. Confirmed name. Second, the level of production and adaptation range in the two years of 1997-1999 to participate in the barley region, respectively, compared with the control Su Yin Mai 2 production 18.59%, 17.92%, reached a very significant level, ranked first in the test varieties. From 1999 to 2000, the average production per mu was 404.5kg, which ranked first in comparison with the control Su Yinmai No. 2 with an increase of 10.38%. The results of experiments and demonstrations show that the variety can be planted in Jiangsu, Anhui, Henan, Hubei and other provinces. Characteristics: The seedlings of this variety are erect, dark green, compact plant type, strong tiller power, high spike-forming rate, multiple mussels, and total number of main leaves is 11. Two-edge long awns, the number of grains per panicle 20-22, the appearance of grain color is good, more than one thousand grain weight 42g, under normal conditions than Su cited Mai 5 high about 5g. Plant height 75-85cm, stems with good elasticity, strong lodging resistance, the whole growth period of about 200 days, similar to Su Yin Mai 2. The ear layer is neat, the cooked phase is good, high resistance to barley yellow mosaic disease, barley stripe resistance, powdery mildew. According to the National Beer Malt Quality Testing Center, it detected 11.6-12% of protein, 79.3% of micropowder leaching rate, 332wk of saccharification power, and 38% of Culbaha, reaching the national standard of high-quality beer and wheat. Fourth, cultivation points 1, suitable for sowing, Huainan wheat district from October 25 to November in early Taiwan, Huaibei wheat area from October 20 to 11 sowing. 2, to take adequate foot basic seedlings, high-yielding cultivation conditions can accommodate 60-70,000 spikes, so get enough foot basic seedlings is a key to high yield. Generally suitable for basic seedlings 16-20 million / acre, late seeding should be appropriate to increase the basic seedlings. 3. Rational fertilizer maneuvering to increase yield and quality. The grain protein content of this variety is about 12%, and it is a panicle type variety. Commodity grain production in the fertilizer operation is based on basic fertilizer, seedling fertilizer, dial-up fertilizer 7:2:1, seed production can be 5:2:3. The total amount of nitrogen applied in a lifetime is 15-18kg, and N:P:K is 1:0.4:0.3. As a commercial grain production, the joint fertilizer should be applied as early as possible, and it is not appropriate to re-inject fertilizer afterwards, otherwise it will affect the quality of beer. 4. Pay attention to the prevention and control of pests and diseases before sowing to prevent seeds from spreading diseases. During heading and flowering seasons, attention should be paid to the management of head blight (Huainan) and armyworm, and attention should be paid to aphid control after heading.
