京农86—6554小麦是北京农科院作物所继丰抗号品种之后,于1989年育成的又一个综合性状好、晚播、早熟、高产的冬小麦新品种。其组合为京农79—1/代177—143。该品种优点之一是耐晚播而早熟。为了筛选耐晚播品种,我们于1989——1990年进行了晚播品种对比试验。10月13日播种,亩基本苗35万。该品种折合亩产419公斤,比对照品种丰抗8号增产15.2％,且早熟2天,差异极显著。该品种优点之二是晚播高产。在耐晚播品种(系)筛选试验中,该品种折合亩产510公斤,比对照丰抗8号增产20.7％,居18个品种之首。栽培要点:京农86——6554小麦属中上高水肥品种,栽培管理上要适当增加肥料投入。特别是底肥
Jingnong 86-6554 Wheat is a new winter wheat variety with good comprehensive characters, late sowing date, early maturity and high yield, which was bred in 1989 after being cultivated by Beijing Academy of Agricultural Sciences. The combination of Beijing agricultural 79-1 / on behalf of 177-143. One of the advantages of the variety is late maturity and early maturity. In order to screen late-sowing varieties, we carried out the late-sowing variety comparison test in 1989-1990. October 13 planting, basic seedlings 350,000 mu. The variety yield 419 kg per mu, compared with the control varieties Fengkao 8 15.2% yield increase, and precocious 2 days, the difference was significant. The second advantage of the variety is late sowing high yield. In the screening of late-sowing varieties (lines), the yield was 510 kg per mu, 20.7% more than the control Feng-8, ranking first in 18 varieties. Cultivation points: Jingnong 86--6554 Triticum is a high water and fertilizer varieties, cultivation and management should be appropriate to increase fertilizer inputs. Especially the base fertilizer
