【摘要】 孙全德,白有善,韩俊杰。稻茬麦旋耕撒播生育特点、栽培指标和肥水技术研究。生态农业研究,1996,4(3):74~76。 对稻茬麦旋耕撒播的生育特点进行了具体研究,其生长发育具有营养体小、前慢后快、蘖多成穗低、粒少不轻4个特点。提出了栽培指标和邯分87-2小麦“大密度中株型偏穗重型”的高产途径。确定了K和Zn的增产作用,并分析了N、P、K、Zn配合施用促进小蘖和次生根的发生、但分蘖骤变型两极分化而不恶化群体的效应。据水分动态提出灌水技术。

【Abstract】 Extensive researches have been carried out to study the growth features of wheat planted after rice by rotary tillage and broadcast sowing.The growth and development of the-wheat can be generalizied into four obivious features as following:small nutritive organ,slowly development at earlier stages while quickly at later stages.abundant tillers with lower percentage of productive tillers,less number of grains but heavy grain weight.Cultivation indexes and high yield measures for heavy panicle weight and medium height wheat variety such as Hanfen 87-2 planted at high density are put forward.The yield increase effects of potassium and zinc are confirmed.The combining dressing of nitrogen,phosphorus,potassium and zinc can generate productive young tillers and secondary roots.Furthly the irrigation technicals are presented in related to the dynamics of soil water.
