| 摘 要： | 为评价小麦养分专家系统(Nutrient Expert,NE)推荐施肥对冬小麦产量效应、养分利用率和农田环境效应的影响,对2010~2014年期间在河北省开展的83个小麦试验进行了分析。结果发现:小麦养分专家系统推荐施肥量较农民习惯施肥量氮、磷肥分别降低了47.0%和10.4%,钾肥增加了102.0%;小麦养分专家系统推荐施肥较农户施肥增产在2.6%~13.0%之间,氮、磷、钾肥利用率分别为31.7%、10.9%和31.0%,氮肥偏生产力为47.9kg/kg,显著高于农民习惯施肥处理24.7 kg/kg;小麦养分专家系统推荐施肥的农田温室气体排放总量和排放强度分别为2 211 kg CO_2 eq/hm~2和332 kg CO_2 eq/t,显著低于农民习惯处理的3 720 kg CO_2 eq/hm~2和589 kg CO_2 eq/t。小麦养分专家系统推荐施肥提高了养分利用率、降低了农田温室气体排放,可以在河北省小麦主产区推广应用。

| Abstract: | This research evaluated the wheat yield effect, nutrient use efficiency and environmental effects of fertilizer rec-ommendation method of nutrient expert system ( NE) in Hebei province. Totally 83 wheat experiments were conducted dur-ing 2010 to 2014 wheat seasons. The results showed the NE recommendation significantly reduced N and P2O5 application rate by 47. 0% and 10. 4%, respectively, than farmer' s practice, but significantly increased K2O input by 102. 0%. The NE recommendation increased wheat yield by 2. 6% ~13. 0%, and the N, P2O5 and K2O fertilizer use efficiencies were 31. 7%, 10. 9% and 31. 0%, respectively. The PFP-N for NE recommendation was 47. 9 kg/kg, which was significantly higher than that of farmers' practice, which was 24. 7 kg/kg. The total greenhouse gas ( GHG) emission and GHG emis-sion intensity for NE recommendation was 2211 kg CO2 eq/hm2 and 332 kg CO2 eq/t, respectively, which were significant-ly lower than those of farmers' practice, which were 3720 kg CO2 eq/hm2 and 589 kg CO2 eq/t. The NE recommendation for winter wheat should be popularized and applied in Hebei. |
