通过多年多点的高产攻关 ,对不同穗型高产冬小麦产量构成因素进行了研究。结果表明 :大穗型品种 ,栽培的主攻方向是穗重 ,但其分蘖成穗率低 ,应适当增加播种量 ,以获得理想穗数 ;多穗型品种 ,栽培的主攻方向是穗多 ,但其分蘖成穗率高 ,应适当减少播种量 ,既要获得足够穗数 ,又要防止倒伏 ;中穗型品种 ,栽培的主攻方向是在穗足的条件下 ,争取穗重。中穗型品种 ,取得高产的机率高 ,因此 ,超高产育种 ,应选育中穗型品种。 Through many years of high-yielding research, the yield components of high-yielding winter wheat with different panicle types were studied. The results showed that the major panicle cultivars were panicle weight, but their panicle tillers had a low panicle rate. The sowing rate should be increased properly to obtain the optimal panicle number. For the panicle type, The tillering into the ear, should be appropriate to reduce the amount of sowing, it is necessary to obtain enough spikes, but also to prevent lodging; medium-spike-type, cultivation of the main direction of the spike foot conditions for spike weight. Mid-spike varieties, high probability of obtaining high yield, therefore, super-high-yielding breeding, mid-spike varieties should be selected.
