Aqueous extract of cotton has allelopathic effect on Raphanus sativus, Brassica campestris, Lactuca indica, Brassica campestris, Echinochloa crusgall, Setaria viridis and Abutilon theophrasti and its inhibition effect gradually strengthens with increasing concentration. Aqueous extracts from stems, leaves and roots of cotton inhibit or accelerate seed germination and seedling growth, and activity of enzyme of seedling root of cotton. While aqueous extracts from stems and leaves of cotton are 0.02 gmL^(-1), root length, shoot length, lateral root number and dry weight of cotton respectively increase by 10.3%, 3.1%, 22.9% and 2.4% over the control. The above mentioned indexes are lower than the control by 34.4%, 39.2%, 40.6% and 19.0% respectively as the aqueous extracts are 0.1 gmL^(-1). At the same time, root activity and SOD activity decrease by 38.2% and 36.7%, while POD activity and MDA content increase by 52.3% and 36.5%. Growth indexes of plant receptors increase at low concentrations but decrease at high concentrations of aqueous extracts. The allelopathic effect of aqueous extract of stems and leaves is stronger than that of root.
结果表明:棉花植株水浸提液对萝卜、白菜、莴苣、油菜、稗草、狗尾草、苘麻均具有化感效应,随着作用浓度增加,抑制效应逐渐加强;棉花茎叶和根系水浸提液对棉花种子萌发、幼苗生长、幼苗根系活力、根系酶活性有抑制或促进作用,当茎叶浸提液浓度为0.02 gmL^(-1)时,棉花根长、苗高、侧根数、干重分别比对照增加10.3%、3.1%、22.9%和2.4%,当浓度为0.1 gmL^(-1)时,上述指标与对照相比分别降低34.4%、39.2%、40.6%和19.0%,而根系活力、SOD活性比对照降低38.2%、36.7%,POD活性、MDA含量较对照增加52.3%和36.5%,不同浓度棉花植株水浸提液对棉花生长呈现"低促高抑"的规律,且茎叶浸提液作用效应大于根系浸提液。

This paper chooses residual income model to measure the cost of equity capital, and construct some index to represent the total disclosure quality and earnings disclosure quality of Chinese listed companies. Our analysis shows that for the whole sample of listed companies which conduct seasoned equity offerings in the stock market, controlling 6, company scale, B/M, leverage and asset turnover, there is positive relationship between the total disclosure quality and marginal cost equity capital; there is negative relationship between the earnings radical and marginal cost equity capita; there is no remarkable relationship between the earnings smoothness and marginal cost equity capital.
本文采用剩余收益模型计算公司的股权融资成本,分别以披露总体质量和盈余披露质量作为反映我国上市公司信息披露质量的指标,研究发现在控制β系数、公司规模、账面价值比、盈利水平等因素的条件下,总体来看,信息披露总体质量越高的样本公司的边际股权融资成本越高;盈余激进度与边际股权融资成本负相关;而盈余平滑度与边际股权融资成本的关系并不显著。

DI is the most ideal irrigation indicator as it is very much influenced by soil water potential and less affected by meteorological factors. DI value of zero is probably the best irrigation threshold. MDS is strongly affected by meteorological factors and requires reference MDS under well-irrigated conditions. RT on the other hand is not significantly related with soil water potential. Therefore neither of these variables is suitable as irrigation index.
DI 受土壤水势影响产生变化的趋势明显并受气象因子影响较小,是最理想的灌溉控制指标,可将 DI =0作为灌溉控制临界值; MDS 受气象因子影响强烈,变异性较大,且需要充分灌溉条件下的 DI 作为参考, RT 与土壤水势的相关性不高,因此均不适合单独作为灌溉控制指标。
