黔西北山区小麦产量与施肥量的关系研究
Research on the Relationship Between Wheat Yield and Fertilization Rate in Northwest of Guizhou Mountain Area
摘要
Abstract
In order to guide scientific fertilization in wheat field in the northwest of Guizhou Mountain ,the rela‐tionship of fertilization rate and wheat yield were studied ,based on“3414”fertilizer experiment at Hongyan vil‐lage in Haizijie town of Bijie city .The results showed that wheat yield was improved after application of N ,P and K fertilizers ,and it reached 6 193 kg·hm‐2 and increased 55 .49% compared with unfertilized treatment ;wheat yield improved significantly with increasing N fertilizer rates .Though the increasing of P and K fertilizer application rate could increase wheat yield ,but the increasing was not significant ;the maximum fertilizer amounts of wheat yield were N 107 .38 kg·hm‐2 ,P2O598 .70 kg·hm‐2 and K2O 85 .11 kg·hm‐2 .关键词
