对稻茬麦旋耕散播的生育特点进行了具体研究,其生长发育概括为“营养体小、前慢后快、蘖多成穗低、粒少不轻”四大特点。提出了栽培指标和邯分87-2的“大密度中株型偏穗重型”的高产途径。确定了钾和锌的增产作用,并分析了氮磷钾锌四元素配合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。
The characteristics of reproductive development of rice stubble rotation were studied in detail. The growth and development of the stubble crop were summarized as four characteristics: “small body of nutrition, slow before and after fast, less tillers and fewer spikes, less grain and no less”. Proposed cultivation indicators and the Hanfen 87-2 “large density middle ear heavy panicle type” high-yielding ways. The effects of potassium, zinc and zinc on yield increase were analyzed. The results showed that the four elements NPK promoted the development of small and secondary roots. However, the tillering mutation did not aggravate the population. According to the dynamic water proposed irrigation technology.
