长期施肥对黑垆土冬小麦、玉米产量和磷素利用效率的影响
Influences of Long-term Fertilizations on Phosphorus Use Efficiencies and Yield of Winter Wheat and Corn in Black Loessial Soil
摘要
Abstract
Based on long-term fertilization experiment during 28 years (1979—2007)in Pingliang,different fertilization treatments including fertilizers,manure,corn straw on phosphorus use efficiencies and yield for winter wheat and corn in wheat-corn rotation system are studied in black loessial soil. The result shows that under Long-term phosphorus fertilizer (NP,SNP,M, MNP)of winter wheat production for 3 519~4 621 kg/hm2,corn is 5 303~6 332 kg/hm2,and its increased 2~4 times compared with CK and N treatments. The different P application treatments had no statistical significant for yeild of winter wheat and corn. And all P treatments of corn uptake are higher than winter wheat. After 28 years of P application,the agronomic efficiency of P fertilizer for corn is 12.42~77.10 kg/kg,and winter wheat is 9.13 ~73.41 kg/kg;the recovery efficiency of P fertilizer for corn about 5.18%~30.15%,and winter wheat is 2.93%~20.07%. The average agronomic efficiency of P fertilizer and recovery efficiency of P fertilizer for corn are higher than winter wheat.关键词
