针对盐城市的气候特点,通过对 啤麦生产与气象条件的关系及其在实际 生产中的应用进 行的试 验研究,认 为:①在目 前气候 变暖 的情况 下,以 10 月 下旬 末到 11 月 初播种 适宜;② 基本 苗控制 在200 万 /h m 2 左右为宜。氮肥用量约 200~260 k g/hm 2 之间为 宜。对提高单产而言,穗 肥比例约 20% ~30% 适中。但为了兼顾品质,穗肥比例在此基础上可适当降低。需磷肥约 100~120 k g/hm 2 ;③主 要生产对策是:适 当降低基本苗,适 期播种,以培育壮苗 越冬,促进冬 前分蘖成 大穗为目 标,主要措 施是早施 苗肥。冬季控制群体,对个别生长明显过旺,生育期明显提前的田块进行 镇压或割青处理。冬后严控 无效分蘖的增加,适期追施返青拔节肥和穗肥 ,加强 对病、虫、草害的防治和防止涝、渍害的发生。后期要 以防早衰为重点,加强田间管理,通过肥控措施促进 大穗的形成和粒重的提高。成熟后要特别注意 天气变化,掌握在蜡熟末期到完熟初期收获。 According to the climate characteristics of Yancheng City, through the relationship between beer production and meteorological conditions and its application in the actual production of the pilot study, that: ① in the current climate warming, late October to early November Sowing appropriate; ② basic seedling control at 2000000 / h m 2 is appropriate. Nitrogen dosage of about 200 ~ 260 kg / hm 2 is appropriate. To improve the yield, the ratio of about 20% to 30% of spike moderate. However, in order to take both quality into account, the proportion of spike and fertilizer can be appropriately reduced on this basis. The main production measures are: appropriate to reduce the basic seedlings, suitable for sowing, in order to cultivate strong seedlings overwinter, and promote the tillering into large ears as the goal, the main measure is to apply early seedling fertilizer . Winter control groups, individual growth was significantly over-Wang, significantly earlier period of growth of plots to suppress or cut green treatment. After winter to strictly control the increase of tillering, the appropriate topdressing fertilizers and spike fertilizer, to strengthen the disease, insects, grass damage prevention and prevention of waterlogging, waterlogging occurs. The latter should focus on preventing premature aging, strengthen field management, and promote the formation of large ears and grain weight through fertilizer control measures. After maturity to pay special attention to changes in the weather, in the mature end of the wax to mature early harvest.
