| 摘 要： | 以豫麦13、郑太育1号、临汾7203、郑州941、豫麦47、郑州8998、郑麦9023、郑麦9694、郑麦9962等9个小麦品种为试验材料,通过17年6个不同施肥方式的长期定位试验,研究了不同施肥处理对小麦产量及构成因素的影响。结果表明:氮素和磷素是限制小麦产量和生长的两个重要因素。钾素不是限制小麦生长及产量的主要因素。NPK和NP处理的产量、穗数、穗粒数都要极显著高于其他处理,而千粒重则为PK处理最高。NPK处理不但高产,而且产量较稳定。从产量的稳定性上来说,NPKPKNPCKNNK。NPK和NP处理的产量与穗数和千粒重达到极显著正相关,而与穗粒数相关不显著。NK和N处理的产量与3个构成因素都成显著正相关。CK和PK处理的产量只与穗粒数成显著正相关。

| Abstract: | 17-year-long-term fertilization experiments with 9 wheat varieties(Yumai 13,Zhengtaiyu1,Linfen7203,Zhengzhou 941,Yumai 47,Zhengzhou 8998,Zhengmai 9023,Zhengmai 9694,Zheangmai9962)in Fluvo-aquic soil were conducted in research farm in Henan Academy of Agricultural Sciences.The effects of different fertilization treatments on grain yield and yield components were studied.The results showed follows:N and P were two crucial limited factors to grain yields and growth of wheat,however,K was not.The grain yields,e... |
