为探究叶面施硒（se）对燕麦籽粒硒积累和营养品质的强化作用，以坝莜6号，坝莜12号，白燕2号3个燕麦品种为研究对象设置田间试验，于扬花期叶面喷施不同浓度(12 g/hm2，se1；36 g/hm2，se2)的硒营养液(seO32-)，同时以不喷硒的处理作为对照，通过测定灌浆期籽粒硒含量以及成熟期营养品质（氨基酸和脂肪酸），分析叶面施硒对燕麦灌浆期籽粒硒积累及成熟期营养品质的强化作用。结果表明，随灌浆时间延长，燕麦籽粒硒含量呈先升高后降低的趋势。其中，成熟期施硒各处理籽粒硒含量均在0.10～0.30 mg/kg的国家标准范围内，显著高于不施硒的对照，且在se2处理下籽粒硒含量最高为0.16 mg/kg。与不施加硒肥的对照相较，施硒明显提高了3个品种燕麦籽粒中总氨基酸的含量：低氨基酸品种坝莜6号的总氨基酸含量增加了2.13%～10.53%，高氨基酸品种白燕2号的总氨基酸含量增加了7.44%～9.37%。与不施硒的对照相比，施硒促进了3个燕麦品种籽粒中不同脂肪酸的含量，且品种类型、硒肥浓度及二者的互作效应的影响均达到极显著水平（P＜0.01）。说明叶面喷施硒肥能显著促进燕麦籽粒硒积累，强化籽粒氨基酸和不饱和脂肪酸的含量，其中以se2处理的效果更好。

Strip deep rotary tillage combined with controlled-release urea improves the grain yield and nitrogen use efficiency of maize in the North China Plain

引用

Journal of Integrative Agriculture 2022年第9期21卷 2559-2576页

作者： han Yu-ling GUO Dong MA Wei GE Jun-zhu LI Xiang-ling ali Noor MEHMOOD ZHAO Ming ZHou Bao-yuan Institute of Crop Sciences Chinese Academy of Agricultural Sciences/Key Laboratory of Crop Physiology and EcologyMinistry of Agriculture and Rural AffairsBeijing 100081P.R.China College of Agriculture Northeast Agricultural UniversityHarbin 150030P.R.China College of Agronomy&Resource and Environment Tianjin Agricultural UniversityTianjin 300384P.R.China College of Agronomy and Biotechnology Hebei Normal University of Science&TechnologyQinhuangdao 066004P.R.China

Inappropriate tillage practices and nitrogen(N) management have become seriously limitations for maize(Zea mays L.) yield and N use efficiency(NUE) in the North China Plain(NCP). In the current study, we examined the effects of strip deep rotary tillage(ST) combined with controlled-release(CR) urea on maize yield and NUE, and determined the physiological factors involved in yield formation and N accumulation during a 2-year field experiment. Compared with conventional rotary tillage(RT) and no-tillage(NT), ST increased the soil water content and soil mineral N content(Nmin) in the 20–40 cm soil layer due to reduction by 10.5 and 13.7% in the soil bulk density in the 0–40 cm soil layer, respectively. Compared with the values obtained by common urea(CU) fertilization, CR increased the Nmin in the 0–40 cm soil layers by 12.4 and 10.3% at the silking and maturity stages, respectively. As a result, root length and total N accumulation were enhanced under ST and CR urea, which promoted greater leaf area and dry matter(particularly at post-silking), eventually increasing the1 000-kernel weight of maize. Thus, ST increased the maize yield by 8.3 and 11.0% compared with RT and NT, respectively, whereas CR urea increased maize yield by 8.9% above the values obtained under CU. Because of greater grain yield and N accumulation, ST combined with CR urea improved the NUE substantially. These results show that ST coupled with CR urea is an effective practice to further increase maize yield and NUE by improving soil properties and N supply, so it should be considered for sustainable maize production in the NCP(and other similar areas worldwide).

*** Zirconium(Zr)and its alloys show great applications in nuclear and chemical industry thanks to their appropriate mechanical properties,low thermal neutron absorption cross-section and excellent corrosion resistance[1–3].Zr displays three different crystal structures on the temperature-pressure phase diagram:the hexagonal close-packed structure(HCP,α-Zr),the body centered cubic structure(BCC,β-Zr)and the simple hexagonal structure(ω-Zr).
