长期定位施肥对不同专用型小麦产量及其构成因素的影响
Effects of Long-term Fertilization on Yield and its Components of Wheat with Different End Uses
摘要
Abstract
Objective] In order to understand the effects of long-term fertilization on yield and its components of wheat,provde scientific basis for reasonable fertilization,optimizatim of cultivation measure.and improving wheat yield in yellow fluvo-aquic soils.[Method] Xumai 32and Ningmai 13 with different end uses were used to study the characteristics of wheat yield and its components based on the 33-year fertilization ex-periment.[Result] The results showed that organic fertilizer,inorganic fertilizer,varieties and interactions between them had significant or very significant effect on yield and its components.In Xumai32 and Ningmai13 background,the effects on ear number per unit,grain number per ear, 1 000-grain weight and yield were consistent .Ear number per unit ,grain number per ear and yield of organic fertilizer were significantly higher than that of the corresponding inorganic fertilizer treatments,except for M treatment.The inorganic fertilizer could significantly increase Ear num-ber per unit,grain number per ear and yield on the basis of organic fertilizer ,but not for 1 000-grain weight,and the effect was equivalent to that of N,NP or NPK fertilizer.In all inorganic fertilizer treatments,ear number per unit,grain number per ear,1 000-grain weight and yield of NPK and NP treatment was significantly higher than that of N and CK treatment ,the yield could not be increased by long term application of N fertiliz-er,it needs to be cooperated with the use of P or PK fertilizer.Correlation analysis showed that the correlation between yield and its components under the main treatment of organic fertilizer was weakened ,which suggested that the long-term use of organic fertilizer made up the effect of the deficiency of inorganic fertilizer.[Conclusion] It’s needed for us to use inorganic fertilizer with the use of organic fertilizer for wheat production in the yellow fluvo-aquic soils,and avoid the yield loss caused by the long-term single fertilizer application.关键词
