摘要:

【目的】研究化肥减量配施腐殖酸肥对北疆超晚播冬小麦产量、氮磷养分吸收利用及土壤肥力的影响,为新疆超晚播冬小麦化肥减量增效、提升麦田土壤肥力和调整小麦施肥结构提供科学依据和参考。【方法】设7个处理,分别为(1)常规施氮处理,NF;(2)优化施氮处理,OPT(80%常规施氮);(3)无氮处理,N0;(4)无磷处理,P0;(5)有机无机配施处理1,NM1(OPT配施腐殖酸肥1.80 kg/hm2);(6)有机无机配施处理2,NM2(OPT配施腐殖酸肥3.60 kg/hm2);(7)有机无机配施处理3,NM3(OPT配施腐殖酸肥5.40 kg/hm2)。【结果】与常规施氮相比,80%常规施氮配施不同剂量腐殖酸肥超晚播冬小麦穗数提高了16.42%~24.16%,穗粒数提高了4.35%~12.42%,产量提高了13.93%~32.48%,地上部植株氮素积累量提高了2.08%~9.83%,磷素积累量提高了16.08%~30.62%,REN34.92%~71.68%,AEN提高了164.49%~350.28%,PFPN提高了42.41%~65.61%,REP提高了87.23%~166.09%,AEP提高了166.67%~388.30%,PFPP提高了13.92%~32.49%。0~20 cm土壤全氮含量提高7.59%~46.84%,有机质含量提高了31.79%~50.76%,有效磷含量提高63.31%~78.92%,速效钾含量提高12.63%~17.20%。【结论】选择氮肥减量20%配施腐殖酸肥5.40 kg/hm2对提高新疆北疆超晚播冬小麦产量、氮磷吸收利用和土壤肥力的效果最佳。

Abstract:

【Objective】 This study aims to investigate the effects of chemical fertilizer reduction combined with humic acid organic fertilizer on yield, nitrogen, phosphorus uptake and utilization, and soil fertility of the extremely-late winter sown wheat in Northern Xinjiang in the hope of providing scientific basis and reference for fertilizer reduction and efficiency increase, soil fertility improvement and adjustment of wheat fertilizer structure in Xinjiang.【Methods】 Seven treatments were designed, including (1) conventional N fertilization, NF; (2) optimized fertilization (80% conventional N fertilization), OPT; (3) no N fertilizer, N0; (4) no P fertilizer, P0; (5) OPT application combined with humic acid fertilizer 1.80 kg/hm2, NM1; (6) OPT application combined with humic acid fertilizer 3.60 kg/hm2, NM2; (7) OPT application combined with humic acid fertilizer 5.40 kg/hm2, NM3. 【Results】 Compared with NF, application of 80 % conventional N fertilization combined with different doses of humic acid fertilizer in extremely-late winter sown wheat, the spike number increased by 16.42%-24.16%, grain number increased by 4.35%-12.42%, the yield increased by 13.93%-32.48 %, the total nitrogen uptake increased by 2.08%-9.83%, the total nitrogen uptake increased by 16.08%-30.62%, REN increased by 34.92%-71.68%, AEN increased by 164.49%-350.28%, PFPN increased by 42.41%-65.61%, R E P increased by 87.23%-166.09%. AEP increased by 166.67%-388.30%, PFPP increased by 13.92%-32.49%. and in 0-20 cm soil, the total nitrogen content increased by 7.59%-46.84%, the organic matter content increased by 31.79%-50.76%, the available phosphorus content increased by 63.31%-78.92%, the available potassium content increased by 12.63%-17.20%. 【Conclusion】 80% conventional N fertilization application combined with humic acid fertilizer 5.40 kg/hm2 has best effect on improving the yield nitrogen, phosphorus uptake and utilization and soil fertility of extremely-late winter sown wheat in northern Xinjiang.
