鄂皮5号大麦高产栽培配套技术的研究

Stuies on the Necessary Techniques of High-Yield Cultivation in E-pi No. 5 Barley

多年大面积栽培和专项试验研究表明，鄂皮５号高产基础的主效应来自有效穗数，在争总穗数的前提下，减小穗粒数和粒重的间接负效应，是取得高产的途径。由此，总结出了中群体，争足穗，争大穗的促－控－争高产栽培配套措施。

The studies of cultivation and spoific-objective experiments were conducted with large acreageover several-year peried. The results showed that the dominant effect of high-yield foundation lay in the avail-able ear quantity, provided striving for sufficicnt total ear quantity, the way to obtain high-yield was decrease theindirect adverse effect of seed number and seed weight of individual ear. A necessary high-yield cultivationmethod, promotion-control-striving,was developed which mainly included medium-sized population, suffi-cient ear quantityand larger spike.
