| 摘 要： | 砂姜黑土10年定位试验结果表明:施肥是砂姜黑土小麦增产的关键,N肥增产贡献率为69.4%,P肥增产贡献率为23.3%,K肥为7.3%。P、K肥的肥效随时间的推移逐渐提高。凡施肥处理土壤有机质含量都有所提高,施P处理土壤速效P含量提高幅度较大,每年每公顷施135kg K2O尚不能满足一年两季作物的高产需求,应适当提高K肥用量。

| Abstract: | The results of a 10-years located experiment showed that fertilization was the key measure to increase wheat yield.The contribution rates of N,P and K fertilizers to yield increase were 69.4,23.3 and 7.3%,respectively.All treatments of fertilization could enhance the content of organic matter.Applying P fertilizer could improve the content of available P,but applying 135kgK2O per hectare per year did not yet meet the high production need of two croppings in a season.It is therefore necessary to enlarge K fertilizer rate suitably. |
