稻纵卷叶螟实验种群模拟模型     

张润杰  古德祥 《中山大学学报论丛》1989,(1)

通过5种温度处理(19℃,22℃,25℃,28℃和31℃),探讨稻.卷叶螟实验种群的数量动态.25℃度温度处理组的世代存活率最高(19.7%),种群增长指数最大(14.9倍)。上述两项指标最低的是19℃温度处理组,分别为3.59b和1.18.根据实验结果,组建了该虫实验种群生命表,并建立了模拟种群数量变化的连续模型和等龄期结构的矩阵模型。  相似文献

浅析张爱玲《秧歌》的真实性     

章秀完 《三明学院学报》2012,29(3):40-44

历史真实和艺术真实两方面是对张爱玲的《秧歌》进行探讨一个视角。在历史不可复制的情况下,《秧歌》与四五十年代的土改小说进行对比中发现,《秧歌》思想倾向性上的"反共"是其被指责陷入虚假的主要原因;但思想的倾向性有别于艺术的真实性,《秧歌》通过对谭大娘、金根、月香、王同志、顾刚等人物形象的塑造,表现了时代历史的大格局下凡常个体的生存境遇与真实的人情人性,做到了艺术的真实。  相似文献

陈华  梅承英  李厚岩 《安徽科技学院学报》2000,(3)

用粉渣代替部分粮食喂肥育猪。试验用 30千克左右的长白杂交猪 2 0头 ,分成试验和对照组 ,每组 1 0头 ,公母各半 ,试验组饲喂用粉渣代替部分粮食的自配饲料 ,而对照组饲喂常规配合饲料。结果表明试验组与对照组净增重、日增重和日耗料无显著差异 ,而试验组的日支出低于对照组的 ,日增收高于对照组的。暗示粉渣可代替部分粮食喂猪  相似文献   

Production of bacterial blight resistant lines from somatic hybridization between Oryza sativa L.and Oryza meyeriana L.     

严成其  钱凯先  薛刚平  吴忠长  陈跃磊  颜秋生  张雪琴  吴平 《浙江大学学报(A卷英文版)》2004,5(10)

Novel bacterial blight (BB) resistance gene(s) for rice was (were) introduced into a cultivated japonica rice variety Oryza sativa (cv. 8411), via somatic hybridization using the wild rice Oryza meyeriana as the donor of the resistance gene(s). Twenty-nine progenies of somatically hybridized plants were obtained. Seven somatically hybridized plants and their parents were used for AFLP (amplified fragment length polymorphism) analysis using 8 primer pairs. Results confirmed that these plants were somatic hybrids containing the characteristic bands of both parents. The morphology of the regenerated rice showed characters of both O. sativa and O. meyeriana. Two somatic hybrids showed highest BB resistance and the other 8 plants showed moderate resistance. The new germplasms with highest resistance have been used in the rice bfeeding program for the improvement of bacterial blight resistance.  相似文献   

Effects of nitrogen fertilization strategies on nitrogen use efficiency in physiology,recovery, and agronomy and redistribution of dry matter accumulation and nitrogen accumulation in two typical rice cultivars in Zhejiang,China     

Xie WX  Wang GH  Zhang QC  Guo HC 《Journal of Zhejiang University. Science. B》2007,8(3):208-216

Field experiments were conducted in farmers’ rice fields in 2001 and 2002 to study the effects of nitrogen (N) management strategies on N use efficiency in recovery (RE), agronomy (AE) and physiology (PE) and redistribution of dry matter accumulation (DMA) and nitrogen accumulation (NA) in two typical rice cultivars in Jinhua, Zhejiang Province. This study aimed mainly at identifying the possible causes of poor fertilizer N use efficiency (NUE) of rice in Zhejiang by comparing farmers’ fertilizer practice (FFP) with advanced site-specific nutrient management (SSNM) and real-time N management (RTNM). The results showed that compared to FFP, SSNM and RTNM reduced DMA and NA before panicle initiation and increased DMA and NA at post-flowering. There is no significant difference between SSNM and FFP in post-flowering dry matter redistribution (post-DMR) and post-flowering nitrogen redistribution (post-NR). These results suggest that high input rate of fertilizer N and improper fertilizer N timing are the main factors causing low NUE of irrigated rice in the farmer’s routine practice of Zhejiang. With SSNM, about 15% of the current total N input in direct-seeding early rice and 45% in single rice could be reduced without yield loss in Zhejiang, China.

Discrimination of rice panicles by hyperspectral reflectance data based on principal component analysis and support vector classification     

Zhan-yu Liu  Jing-jing Shi  Li-wen Zhang  Jing-feng Huang 《Journal of Zhejiang University. Science. B》2010,11(1):71-78

Detection of crop health conditions plays an important role in making control strategies of crop disease and insect damage and gaining high-quality production at late growth stages. In this study, hyperspectral reflectance of rice panicles was measured at the visible and near-infrared regions. The panicles were divided into three groups according to health conditions: healthy panicles, empty panicles caused by Nilaparvata lugens Stul, and panicles infected with Ustilaginoidea virens. Low order derivative sp...  相似文献   

城市文化——罪恶的渊薮——苏童小说《米》的再解读     

侯敏 《丹东师专学报》2010,(1):87-90,101

苏童摆脱了对创作短篇小说的一度迷恋,写作了长篇＂新写实小说＂《米》。《米》已经被人们做了诸多的归纳与阐释,但最根本的还是要借一个逃亡与回归的故事母题,去写一个在城市文化中人性被扭曲的、孤独无依的人的具有悲剧意义的一生。于是逃亡与回归、人性的扭曲、生命的孤独便构成了苏童小说《米》叙述的基本元素。本文就试图通过这些跳荡在作品中的元素,来透视这些元素背后的城市的淫靡文化是如何摧毁了一个乡村青年的生命的。  相似文献
