研究了暖冬春寒严重冻害情况下，扬麦１５８稻田套播、稻后零耕撒播、稻后翻耕撒播３种栽培方式，认为：套播栽培虽主茎冻死率达１００％，Ⅰ、Ⅱ、Ⅲ低蘖位分蘖冻死７６％，但补偿性恢复能力特强，越冬期与春后分蘖占总分蘖的８４．３％，成穗率４３％，成穗占总穗数的９４％；零耕主茎亦冻死１００％，Ⅰ、Ⅱ、Ⅲ低蘖位分蘖冻死５１．９％，一次分蘖穗占总成穗的７２％；翻耕由主茎穗，Ⅰ、Ⅱ低蘖位穗组成
In the case of severe winter cold and freezing frost damage, the three cultivation methods of intercropping of Yangmai 158 in paddy field, zero-plowing in paddy field and transplanting in paddy field were considered. Although the mortality of main stem was 100%, the mortality of Ⅰ, Ⅱ , Ⅲ low tillering tiller tilted 76%, but the compensatory recovery ability is extremely strong, the winter tillering and spring tillering accounted for 84.3% of the total tillering rate of 43%, forming ear accounted for 94% of the total number of spikes; Zero-tillage stem also freeze-dried 100%, Ⅰ, Ⅱ, Ⅲ tillering freeze-dead 51.9%, a tillering panicle accounted for 72% of the total panicle; tillage by the main stem ear, Ⅰ, Ⅱ low tillering position Spike composition
