不同施肥时期对玉米产量和质量的影响
Effects of Fertilizer Application by Different Stages on Yield and Quality of Maize
摘要
Abstract
Field experiment was conducted to investigate effects of nitrogen (N), phosphorus (P) and potassium ( K) fertilizer applications at different stages on agronomic traits, yield and quality of maize. The results indicated that effect of N fertilizer application by different stages on maize was more than effect of P and K fertilizer applications by different stages on maize by the means of field survey and indoor analysis. The economic traits of maize with the treatment of mature, P and K fertilizers applied once as base fertilizer, and N fertilizer applied as 50% seedling fertilizer and 50% ear fertilizer, was better than those with other treatments. And yield with the treatment is 7 919. 5 kg/hm2 and is the highest in all treatments. Contents of protein, crude fat and lysine with the treatment are 14. 96% , 5. 00% and 0. 34% , and they are higher than these with other treatments. The contents of starch, soluble sugar and lysine in maize with the treatment of mature, K fertilizer applied once as base fertilizer, N fertilizer applied as 20% base fertilizer, 30% seedling fertilizer and 50% ear fertilizer, and P fertilizer applied as 50% base fertilizer and 50% seedling fertilizer, are 67. 23% , 2. 45% and 0. 34% andthe highest in all treatments.关键词
