在精播高产栽培条件下,测定了不同品种茎秆高度、粗度、维管束数目、茎壁厚度、节间伸长动态,及其与栽培措施的关系。分析了第二节间长、粗与抗倒能力,穗下节间长度与穗重的关系。精播高产田小麦,茎秆中等高度,基部节间短,穗下节间较长有利于壮秆大穗。选用适宜品种,控制返青、起身肥水,适期播种,施足低肥,适时浇灌冬前水是控制茎秆的有效措施。
Under the conditions of high sowing and sowing, the dynamic changes of stem height, thickness, number of vascular bundles, stem wall thickness and internode elongation of different varieties were measured and their relationships with cultivation measures were determined. The relationship between the length of the second node, the ability of crude and lodging resistance, the length of internodes under panicles and panicle weight was analyzed. Fine sowing high-yielding field wheat, medium stem height, short basal internodes, spikelets internodes are conducive to long stalk. Selection of suitable varieties, control greening, get up fertilizer, sowing the appropriate period, Shi enough low-fat, timely watering before winter is an effective measure to control stalks.
