We studied the effects of temperature and solar radiation on rice yield with the aim of understanding the temperature and solar radiation requirements for high yield rice production in the lower reaches of the Huai River,*** experiments were conducted with two medium-maturing japonica rice(MMJR)varieties and four late-maturing japonica rice(LMJR)varieties in 2017 and *** were sown on May 10(T1),May 17(T2),May 24(T3),May 31(T4),June 7(T5),June 14(T6),and June 21(T7).The whole growth duration(WGD)of rice was shortened when sowing date was delayed,especially for the duration from sowing to heading(S–H).The effective accumulated temperature(EAT),mean daily temperature(Tmean),cumulative solar radiation(CSR),and mean daily solar radiation(Rmean)over the WGD decreased when sowing date was *** with T1,yields in T2,T3,T4,T5,T6,and T7 decreased by 0.12–0.35,0.45–0.89,0.74–1.56,1.41–2.24,2.16–2.90,and 2.69–3.64 t ha^(-1),*** was a significant positive correlation between rice yield and EAT in different growth *** was the main factor that affected the yield of good eating-quality rice in the lower reaches of the Huai *** found that a relatively high yield can be obtained when the optimal Tmean for medium-maturing japonica rice(MMJR)and late-maturing japonica rice(LMJR)was 25.8–27.0℃and 26.6–27.1℃in the stages from sowing to heading(S–H),and 20.3–23.3℃and 20.3–22.1℃in the stages from heading to maturity(H–M),*** optimal sowing dates for MMJR and LMJR in the lower reaches of the Huai River were May 15–31 and May 15–18,respectively.

Combined effect of shading time and nitrogen level on grain filling and grain quality in japonica super rice

引用

Journal of Integrative Agriculture 2018年第11期17卷 2405-2417页

作者： WEI Hai-yan ZHU Ying QIU Shi HAN Chao HU Lei XU Dong zhou nian-bing XING Zhi-peng HU Ya-jie CUI Pei-yuan DAI Qi-gen ZHANG Hong-cheng Jiangsu Key Laboratory of Crop Genetics and Physiology/Jiangsu Co-Innovation Center for Modern Production Technology of Grain Crops/Agricultural College Yangzhou University

There is limited information about the combined effect of shading time and nitrogen （N） on grain filling and quality of rice. Therefore, two japonica super rice cultivars, Nanjing 44 and Ningjing 3, were used to study the effect of shading time and N level on the characteristics of rice panicle and grain filling as well as the corresponding yield and quality. At a low N level （150 kg N ha^-1, 150N）, grain yield decreased （by 21.07-26.07%） under the treatment of 20 days of shading before heading （BH） compared with the no shading （NS） treatment. These decreases occurred because of shortened panicle length, decreased number of primary and secondary branches, as well as the grain number and weight per panicle. At 150N, in the treatment of 20 days of shading after heading （AH）, grain yield also decreased （by 9.46-10.60%） due to the lower grain weight per panicle. The interaction of shading and N level had a significant effect on the number of primary and secondary branches. A high level of N （300 kg N ha^-1, 300N） could offset the negative effect of shading on the number of secondary branches and grain weight per panicle, and consequently increased the grain yield in both shading treatments. In superior grains, compared with 150N NS, the time to reach 99% of the grain weight （T99） was shortened by 1.6 to 1.7 days, and the grain weight was decreased by 4.18-5.91% in 150N BH. In 150N AH, the grain weight was 13.39-13.92% lower than that in 150N NS due to the slow mean and the maximum grain-filling rate （GRmean and GRmax）. In inferior grains, grain weight and GRmean had a tendency of 150N NS〉150N BH〉150N AH. Under shaded conditions, 300N decreased the grain weight due to lower GReen both in superior and inferior grains. Compared with 150N NS, the milling and appearance qualities as well as eating and cooking quality were all decreased in 150N BH and 150N AH. Shading with the high level of 300N improved the milling quality and decreased the number of chalky rice kernels, but

A double-layered protective film based on zinc-based coordination compound and ZnF2-rich solid electrolyte interphase layer has been successfully fabricated on the zinc metal anode via electrode/electrolyte synergistic *** double-layered architecture can effectively modulate Zn2+ flux and suppress the zinc dendrite growth, thus facilitating the uniform zinc *** as-developed zinc-(dual) halogen batteries based on double-layered protective film can present high areal capacity and satisfactory cycling stability. Aqueous zinc-halogen batteries are promising candidates for large-scale energy storage due to their abundant resources, intrinsic safety, and high theoretical capacity. Nevertheless, the uncontrollable zinc dendrite growth and spontaneous shuttle effect of active species have prohibited their practical implementation. Herein, a double-layered protective film based on zinc-ethylenediamine tetramethylene phosphonic acid (ZEA) artificial film and ZnF2-rich solid electrolyte interphase (SEI) layer has been successfully fabricated on the zinc metal anode via electrode/electrolyte synergistic optimization. The ZEA-based artificial film shows strong affinity for the ZnF2-rich SEI layer, therefore effectively suppressing the SEI breakage and facilitating the construction of double-layered protective film on the zinc metal anode. Such double-layered architecture not only modulates Zn2+ flux and suppresses the zinc dendrite growth, but also blocks the direct contact between the metal anode and electrolyte, thus mitigating the corrosion from the active species. When employing optimized metal anodes and electrolytes, the as-developed zinc-(dual) halogen batteries present high areal capacity and satisfactory cycling stability. This work provides a new avenue for developing aqueous zinc-(dual) halogen batteries.

当前"减氮"成为优质食味粳稻种植措施之一,但减氮后的氮肥科学运筹方案尚不够明确,需进一步研究。2018—2019年,选用优质食味粳稻品种‘南粳505’和‘南粳2728’为材料,前茬麦秸秆全量还田,采用机插方式,在总施氮量较当地常规施氮量减少20%条件下,设置基蘖肥和穗肥比例分别为5∶5、6∶4、7∶3和8∶2四种氮肥运筹比例,研究了淮北地区麦茬机插优质食味粳稻氮肥减量精确运筹。结果表明,随着基蘖肥占总施氮量比例增加,产量呈先增后降趋势,7∶3处理产量最高,2年达11,134.80~11,280.19 kg hm^(-2),较CK增产1.23%~2.54%,但差异不显著;7∶3处理群体高产,在于能获得充足的群体颖花量、较高的结实率和千粒重。随着基蘖肥比例增加,有效分蘖临界叶龄期、拔节期群体干物质积累量呈增加趋势;抽穗期、成熟期、抽穗至成熟期的干物质积累量、最终氮素积累量及氮素利用率,呈先增后降趋势,均以7∶3处理最高。与常规施氮处理相比,减氮处理通过增加前期施氮肥比例(7∶3),能确保群体后期获得较高的干物质积累量;成熟期氮素积累量较小,但显著提升了氮素吸收利用率,较CK高14.10%~15.48%,差异显著。减氮后增加基蘖肥比例使优质食味粳稻加工品质变劣,外观品质变优,蒸煮食味品质改善,RVA谱优化。在麦秸秆全量还田条件下,较常规施肥减氮20%,基蘖肥与穗肥运筹7∶3处理优质食味粳稻产量稳定,大幅提升氮素吸收利用率,改善稻米外观和食味品质,在一定程度上实现了优质食味粳稻的高产、优质、高效的综合种植目标。
