THE WAYS FOR IMPROVING INDOOR ENVIRONMENT AND AIR-CONDITIONING SYSTEMS IN DANCLING HALLS     

Dong Qiang 《保鲜与加工》1993,(1)

Since 1988, air temperature, humidity, air quality, noise level and intensity of illumination in lots of dancing halls in China have been investigated and tested. This paper introduces the present situation of indoor environment and air conditioning systems in dancing halls of China. The design indexes of cooling load for room and ontside air are recommended. The reasons for indoor environment deterioration have been found out. From the actual situation of China, the ways for imoroving indoor environment and approach of energy conservation in air conditioning systems are explored.  相似文献

Identification and mapping of a novel Turnip mosaic virus resistance gene TuRBCS01 in Chinese cabbage (Brassica rapa L.)          下载免费PDF全文

We aimed to identify Turnip mosaic virus (TuMV) resistance genes in Chinese cabbage by analysing the TuMV resistance of 43 P₁ (resistant), 88 P₂ (susceptible), 26 F₁, 104 B₁ (F₁ × P₁), 108 B₂ (F₁ × P₂) and 509 F₂ individuals. All parents and progeny populations were mechanically inoculated with TuMV‐C4. Both F₁ and B₁ populations showed TuMV resistance. Resistant: susceptible ratios in the B₂ and F₂ populations were 1 : 1 and 3 : 1, respectively. TuMV resistance in P₁ was controlled by a dominant gene, TuRBCS01. Bulked segregation analysis was performed to identify simple sequence repeat or insertion or deletion markers linked to TuRBCS01. Data from 108 B₂ individuals with resistant or susceptible phenotypes were analysed using mapmake r/exp 3.0. Polymorphic marker sequences were blast searched on http://brassicadb.org/brad/ . TuRBCS01 was found to be linked to eight markers: SAAS_mDN192117a_159 (3.3 cM), SAAS_mDN192117b_196 (4.0 cM), SAAS_mDN192403_148 (13.0 cM), SAAS_mGT084561_233 (6.8 cM), BrID10723 (3.3 cM), mBr4041 (3.3 cM), SAAS_mBr4055_194 (2.6 cM) and mBr4068 (4.0 cM). Further, TuRBCS01 was mapped to a 1.98‐Mb region on chromosome A04 between markers BrID10723 and SAAS_mBr4055_194.  相似文献

秸秆还田后少耕对小麦/玉米间作系统中种间竞争和互补的影响   总被引：8，自引：0，他引：8

保护性耕作具有提高作物水分利用效率、减少能耗等优点,但能否将该技术集成应用于间作套种,尚需理论研究和具体实验依据。本研究通过2011至2012年度的田间定位试验,探讨不同耕作和秸秆还田方式对小麦间作玉米作物群体竞争、互补作用及产量的影响。试验设3种秸秆还田处理,分别是小麦带25 cm高茬收割立茬免耕(NTSS)、小麦带25 cm高茬等量秸秆覆盖免耕(NTS)及小麦带高茬等量秸秆还田翻压(TIS),以传统耕作(CT)为对照。秸秆还田后少耕间作的土地当量比高于传统耕作间作,且大于1,说明少耕小麦秸秆还田有利于提高间作优势;少耕秸秆还田降低了共生期小麦相对于玉米的竞争力,以NTS处理对小麦竞争力的影响最大,NTSS、NTS和TIS的小麦全生育期相对竞争力分别降低37%~54%、109%~141%和22%~24%。与单作玉米相比,NTSS、NTS、TIS和CT处理间作玉米的相对生长率分别高54%~59%、66%~71%、61%~63%和71%~78%,其中小麦秸秆还田间作处理中NTS更有利于发挥玉米的恢复效应。间作条件下,3种秸秆还田处理的产量较对照高6%~10%(2011年度)和4%~12%(2012年度),其中NTS增产显著。总体来看,间作群体籽粒产量与小麦相对于玉米全生育期的平均竞争力呈二次相关关系,当该竞争力在0.24~0.27时利于获得间作高产。本研究表明,秸秆还田配合少耕是调控种间竞争力的可行途径,其中小麦等量秸秆(小麦留茬25 cm)还田覆盖是优化小麦玉米竞争力的理想耕作措施。  相似文献
