【摘要】 为筛选出适合冀东地区冬小麦后茬夏谷的减肥增效施肥水平，在前茬小麦季设置12个微生物菌剂与复合肥配施处理，研究前茬冬小麦施肥的肥料后效对后茬谷子(冀谷42号)农艺性状和产量的影响。结果表明：后茬谷子在前茬小麦300 kg/hm~2微生物菌剂+675 kg/hm~2复合肥处理下产量达到最大值，为5971.38 kg/hm~2,与150 kg/hm~2微生物菌剂+675 kg/hm~2复合肥处理下差异不显著，显著高于其他处理。300 kg/hm~2微生物菌剂+675 kg/hm~2复合肥处理下相比0 kg/hm~2微生物菌剂+0 kg/hm~2复合肥、0 kg/hm~2微生物菌剂+675 kg/hm~2复合肥、150 kg/hm~2微生物菌剂+675 kg/hm~2复合肥处理下产量分别提高30.88%,20.10%,5.41%。冀东地区前茬冬小麦施用常规复合肥水平675 kg/hm~2配施300 kg/hm~2微生物菌剂可获得最高的冬小麦-夏谷产量(7 502.73 kg/hm~2-5 971.38kg/hm~2)。更多还原

【Abstract】 Twelve microbial inoculants and compound fertilizer treatments were set to study the aftereffects of winter wheat fertilization on agronomic traits and yield of Jigu42, a late crop of foxtail millet, and select the fertilizer level suitable for reducing fertilizer application and increasing efficiency of summer foxtail millet in Eastern Hebei Province. The results showed that the yield of foxtail millet under 300 kg/hm~2 microbial inoculants and 675 kg/hm~2 compound fertilizer treatment reached the maximum value of 5 971.38 kg/hm~2, which was not significantly different from that under 150 kg/hm~2 microbial inoculants and 675 kg/hm~2 compound fertilizer treatment, but greatly higher than that under other treatments. The yield under 300 kg/hm~2 microbial inoculants and 675 kg/hm~2 compound fertilizer treatment was 30.88%, 20.10% and 5.41% higher than that under 0 kg/hm~2 microbial inoculants and 0 kg/hm~2 compound fertilizer, 300 kg/hm~2 microbial inoculants and 675 kg/hm~2 compound fertilizer and 150 kg/hm~2 microbial inoculants and 675 kg/hm~2 compound fertilizer treatments, respectively. The highest yield of winter wheat-summer foxtail millet(7 502.73 kg/hm~2-5 971.38 kg/hm~2) can be obtained by applying 675 kg/hm~2 conventional compound fertilizer and 300 kg/hm~2 microbial inoculants to the previous crop winter wheat in the Eastern Hebei Province.更多还原
