High-yield Cultivation of Hongmai Beer No. 2 Barley
Hong Kong Beer No. 2 is a new variety of beer and barley selected by the Lianyungang Agricultural Division. In January 2007, it was approved by the Lianyungang City Crop Variety Approval Team. This species is a weak winter pre-spring two-leaf barley, suitable for the whole period of 208 days sowing; the average plant height 89.5 cm, compact plant shape, strong branching force, spike rate, spike length 5.7 cm, per acre 50-55 thousand ear, 21-23 grains per panicle, 1000-grain weight 40-43 grams, long awn, white shell, thin seed coat; the average yield per mu is over 460 kg, and the yield per mu is 520 kg; Good cold resistance, strong moisture resistance, late high temperature and dry hot wind, high resistance to rust, powdery mildew and barley yellow mosaic disease, light stripe disease. The demonstration plantation in Yancheng City during 2006-2007 performed well. The yield per mu in the two years was 469.6 kg and 509.8 kg respectively. The fine soil preparation is suitable for plowing the land, and the plowing depth is more than 20 cm to ensure that the plowing surface is flat and loose. Heavy hydraulic shovels are used, with a depth of 15 to 18 centimeters. Rotary cultivators are used for high-power locomotives with rotary tillage depths of 12-14 cm. Seed treatment Sowing before sowing to increase seed vigor and germination rate. 100 grams of wheat seed each with Xiufeng (2% tebuconazole wet seed dressing agent) 75 grams plus 100 grams (25% prochloraz emulsifiable concentrate) 20 milliliters of water and 8 kilograms of seed dressing, mix and boring after 6-8 hours , Prevention of barley smut and streak disease. It is appropriate to sow the coastal areas of northern Jiangsu for sowing from the end of October to the beginning of November. Other areas can appropriately adjust the sowing date based on the principle that the wheat seedlings can reach 5 leaves and 1 heart during wintering. It is advisable to plant seedlings at the rate of 140,000 to 200,000 per acre under moderate fertility conditions. If sowing is delayed, 4000 seedlings per acre will be added for each postponement of 1 day. Under the fertility conditions of middle and top grade, fertilisers should be replanted with basal fertilization, early application of strong fertilizer, and skillful production of jointing and panicle-fertilizer. Apply 14 kg of pure nitrogen per acre, 8 kg of phosphorus pentoxide and 6 kg of potassium oxide. Phosphorus and potassium fertilizers were used as base fertilizers, 7% of nitrogen fertilizer was used as base fertilizer, 20%-25% was used as fertilizer, and 5%-10% was used as jointing and panicle-fertilizer. In order to increase fertilization uniformity and fertilizer use efficiency, in addition to manual application of jointing panicle-fertilizer, the remaining fertilizers were mechanically applied. Chemically controlled anti-barley bark returning to the jointing stage and the flag leaf blade normal time, respectively, per mu with 50 mg of corn Jianxin spray, can effectively shorten the length of the internode base, inhibit internode elongation under the ear, reduce the risk of lodging. At the same time, clean up the trenches in the field to make the three-ditch support, ensure smooth drainage and prevent rain. Prevention and control of worms before and after the winter of the diseased weeds and weeds, prevention of hoppers and armyworms in the end of March and early April. After planting, 50 ml of Garrett (50% pretilachlor) in 70 ml of wheat suspension (50% isoproturon suspension) per acre was used for soil closure. Residual weeds can be sprayed with 50% isopropenol 80g and 50% acetochlor EC 60ml per acre before or during the spring. Timely harvested barley should be harvested before the wax ripening and ripening period. If the harvest is too early, the germination rate will decrease; if the harvest is too late, the grain protein content will increase and the yield will decrease. 20%-25% of tassels in the field are harvested and sun-dried, and the water content drops to 12.5% ​​or less. After cooling, they are put into storage for quality. Power Driven Harrow,Tractor Drived Power,Power Disc Harrow,Power Roller Harrow Shandong Dahua Machinery Co.,Ltd , https://www.agrodahua.com
