High yield breeding combining with strong ecological adaptability and good quality should be largely based on later maturity, tumorous stem diameter, whole plant weight and higher ratio of stem and leaf.

瘤茎产量与营养生长期、瘤茎膨大期、瘤茎横径、茎/叶、株鲜重呈极显著遗传正相关,与菜形指数、菜皮百分率呈极显著遗传负相关,与其余性状相关均未达显著水平;与瘤茎产量显著相关的性状间关系密切,有很好的协同性,分析提出茎瘤芥育种选择熟性晚、瘤茎横径大、茎/叶高和植株个体较大的品种,可实现品种产量高、生态适应性强和瘤茎品质较佳等三者的协调统一。

The New Rice Variety Liaoxing 1,with high eurytopicity has higher photosynthesis rate,higher stoma conductance,higher SPAD,higher ingather quotiety than other largely planted varieties in Liaoning Province,when planted in the rice area from 39°N to 43°N.Different from other varieties,when planted in four spots in different latitudes,the yield components of Liaoxing 1 change little and so it keeps higher yield level.

It is the inoculable sludge, the peculiarity of wastewater and the framework configuration of the ABR that cause the predominant growth of acidogenic bacteria.(2) The complex containment was gradually removed by sort in the ABR, which showed the ABR has typical characteristics of the plug flow system. Along with the raising of the OLR, The gas yield and rate increase at the same time. The distribution of the gas yield and rate in the ABR is normal school along the way.

对ABR沿程的COD、VFA以及pH的变化规律进行分析,结果表明ABR对有机物的降解过程具有典型的推流系统特征,复杂污染物是以分类逐级的形式得以去除的;污染物的去除主要发生在1~3格室(COD去除贡献为50~80%),随有机负荷的提高,去除主体逐渐后移;系统产气量及沼气产率均随有机负荷的提高而增加;处理红霉素废水时,格室产气量及产气率沿程呈正态分布,分析认为,这是由ABR的特性及废水本身的特点综合作用的结果。
