摘要:

【目的】通过探究不同类型肥料对江淮稻茬弱筋小麦的田间性状、氮素吸收与利用、产量及构成因素、加工品质的影响,以期为江淮地区稻茬弱筋小麦量、质协优的肥料类型选择及施用量的调控提供理论依据。【方法】以弱筋小麦扬麦20和白湖麦1号两个品种为供试材料,试验设置3个氮素水平:150 kg·hm-2(N10)、180 kg·hm-2(N12)、210 kg·hm-2(N14),另设不施氮处理(N0)计算氮效率;4种不同类型肥料:复合肥+尿素(F1)、缓释掺混肥(F2)、控失肥(F3)、小麦配方肥(F4),分析不同处理对弱筋小麦群体动态、氮素利用、产量及品质的影响。【结果】随着氮素水平的升高,弱筋小麦的产量和各项品质指标均有改善。一次性基施缓释掺混肥、控失肥和小麦配方肥能够显著提高小麦花后旗叶SPAD值和成熟期穗数;与复合肥+尿素处理相比,地上部氮素积累量分别提高5.0%—12.8%、0.8%—6.2%和9.9%—17.2%;氮素利用率分别提高10.3%—26.9%、4.3%—16.5%和22.1%—39.8%;开花期旗叶硝酸还原酶(NR)活性分别提高2.6%—8.8%、-2.9%—1.5%、5.1%—12.8%;谷氨酰胺合成酶(GS)活性分别提高9.0%—23.8%、2.0%—8.9%、11.8%—28.7%;谷氨酸合成酶(GOGAT)活性分别提高3.9%—18.4%、0.8%—8.9%、7.7%—24.0%;产量分别提高5.0%—11.5%、1.8%—7.6%、9.7%—18.4%。在施氮水平为180和210 kg·hm-2时,缓释掺混肥、控失肥和小麦配方肥较复合肥+尿素处理产量均有不同程度提高,其中相同氮素水平下,缓释掺混肥和控失肥较复合肥+尿素处理显著降低籽粒蛋白质和湿面筋含量,降低籽粒硬度和溶剂保持力,同时减少面团的形成时间和稳定时间,降低吸水率和粉质质量指数,提高弱化度,改善弱筋小麦的加工品质及面团流变学特性。【结论】江淮地区稻茬弱筋小麦种植,适宜将氮素水平控制在180—210 kg·hm-2,一次性基施缓释掺混肥,能够在保证弱筋小麦品质的同时获得较高的产量。

Abstract:

【Objective】 This research investigated the effects of different types of fertilizers on the field traits, nitrogen absorption and utilization, yield, yield components, and processing quality of weak-gluten wheat following rice cultivation in the Jiang-Huai region. The goal was to provide a theoretical basis for the selection of optimal fertilizer types and regulation of application rates for achieving high yield and quality of weak-gluten wheat in this region. 【Method】 The two weak-gluten wheat varieties, including Yangmai 20 (YM20) and Baihumai 1 (BHM1), were used as experimental materials. The experiment was set three nitrogen levels: 150 kg·hm-2 (N10), 180 kg·hm-2 (N12), and 210 kg·hm-2 (N14), with an additional nitrogen-free treatment (N0) to calculate nitrogen efficiency. Four types of fertilizers were applied: compound fertilizer + urea (F1), slow-release mixed fertilizer (F2), controlled- release fertilizer (F3), and wheat formula fertilizer (F4). The effects of different treatments on wheat population dynamics, nitrogen utilization, yield, and quality were analyzed. 【Result】As nitrogen application levels increased, the yield and quality indicators of weak-gluten wheat improved. The one-time basal application of slow-release mixed fertilizer, controlled-release fertilizer, and wheat formula fertilizer significantly increased the SPAD value of the flag leaf after anthesis and the number of spikes at maturity. Compared with the compound fertilizer+urea treatment, the nitrogen accumulation in the above-ground parts under slow-release mixed fertilizer, controlled-release fertilizer, and wheat formula fertilizer was increased by 5.0%-12.8%, 0.8%-6.2%, and 9.9%-17.2%, respectively; the nitrogen utilization efficiency increased by 10.3%-26.9%, 4.3%-16.5%, and 22.1%-39.8%, respectively; during anthesis, the activities of nitrate reductase (NR) in the flag leaf increased by 2.6%-8.8%, -2.9%-1.5%, and 5.1%-12.8%; glutamine synthetase (GS) activity increased by 9.0%-23.8%, 2.0%-8.9%, and 11.8%-28.7%; and glutamate synthase (GOGAT) activity increased by 3.9%-18.4%, 0.8%-8.9%, and 7.7%-24.0%; yield increased by 5.0%-11.5%, 1.8%-7.6%, and 9.7%-18.4%, respectively. At nitrogen levels of 180 and 210 kg·hm-2, slow-release mixed fertilizer, controlled-release fertilizer, and wheat formula fertilizer all resulted in varying degrees of yield improvement compared with the compound fertilizer+urea treatment. At the same nitrogen levels, slow-release mixed fertilizer and controlled-release fertilizer significantly reduced grain protein content, wet gluten content, grain hardness, and solvent retention capacity compared with the compound fertilizer + urea treatment. They also reduced dough formation time and stability time, lowered water absorption rate, and the farinograph quality number. These treatments also enhanced the dough rheological properties and weakened the gluten strength. 【Conclusion】For weak-gluten wheat cultivation following rice in the Jiang-Huai region, it was recommended to control the nitrogen level at 180-210 kg·hm-2. A one-time basal application of slow-release mixed fertilizer could ensure both high quality and high yield of weak-gluten wheat.
