分析肥料运筹对小麦群体质量的影响表明，小麦一生氮肥适宜运筹比例为基蘖肥占一生总施肥量的６０％左右，拔节孕穗肥占４０％左右，磷、钾肥宜作基肥和返青拔节肥二次施用。前期施氮肥过多易使群体发育不协调，分蘖成穗率降低，粒叶比小，产量低；后期适量施氮并配合磷、钾肥施用，能有效地增加孕穗后光合物质生产，粒叶比大，产量高。
Analysis of the impact of fertilizer management on the quality of wheat population shows that the proportion of wheat nitrogen fertilizer in the whole life is about 60% of the total amount of fertilization on the basis of basal tillering fertilizer and about 40% of the total amount of spike fertilizer in jointing. Phosphorus and potassium fertilizers should be used as basal fertilizer, Application. In the early stage, too much nitrogen fertilizer easily led to uncoordinated population development, reduced panicle tillering rate, small grain-leaf ratio and low yield. After nitrogen application and phosphorus and potassium fertilizer application at the later stage, photosynthetic substance production could be effectively increased after booting, Large, high output.
