摘要
在自然、适宜、充足3种土壤水分和无肥、中肥、高肥3种施肥水平耦合作用条件下,研究水肥对春小麦拔节期、孕穗期、灌浆期有效叶面积和产量的影响。结果表明,春小麦有效叶面积与施肥水平呈正相关,产量以适宜水分高肥耦合最高,为3713kg/hm^2。
In the mutual actions of natural, adaptable,sufficient soil moisture and none,medium, high fertilizer application,the effects of soil water and fertilizer coupling on the efficient leaf area and grain yield of spring wheat are studied. The result shows that the efficient leaf area is positive correlation with fertilizer application level,the highest grain yield (3713kg/hm2) is obtained in ap-propriate soil water and high fertilizer application.
