通过对超高茬麦套稻的产量结构、源库参数等性状的测定分析,结果表明,超高茬麦套稻高产栽培应依据不同穗型,确定适宜的基本苗和N肥运筹措施,在大穗型品种单株成穗5个左右,穗粒并重型品种单株成穗4个以上,每公顷有效穗330万~360万时,群体综合性状最优。同时提出降低基本苗、调节肥水运筹等具体高产栽培技术措施。
Through the analysis on the yield structure and the parameters of the source and sink of super high stubble rice, the results showed that the high yielding cultivation of super high stubble rice should be based on different types of spikes, There were about 5 spikelets per plant and 4 spikelets per panicle in the large spike cultivar, with an effective spike of 3.3-3.6 million spikes per hectare, with the best comprehensive population traits. At the same time to reduce the basic seedlings, fertilizer and water regulation and other specific high-yield cultivation techniques and measures.
