The ethylene release rate was measured in shoot tip of different sex ramie in different time, the budof same node in female and hermaphrodite ramie in second crops and different sex singleinflorescence in hermaphrodite ramie. The result indicated there was closed relationship betweensexual different ramie and ethylene release rate. The female ramie could be induced by highethylene release rate. the ethylene content in ramie plant with female flower is higher than ramieplant with androgynary in stem apex, leaf and flower.

Flat-nosed people are "hard life even buy houses", they did not know what is "real estate bubble"; experts and scholars to understand the bubble, according to China's housing prices and people's income ratio is much higher than international standards, there are is the vacancy rate in international comparison; but officials know how to "bubble" What does it mean, it never recognized the bubble, one that the Chinese have different national conditions, strokes and win one hundred strokes, is the so-called "the nation is a basket, what can be fitted inside" and second that different statistical data, you have your vacancy rate, and I have mine vacancy rate, the three said that even if there is also a partial bubble bubble, should not in addition to all; the most optimistic real estate developers, think China's real estate is in a the rapid development stage, there is no bubble in the shadow, the most credible, because recognition of the bubble, not only means that the property market even if it does not collapse, will be handover to the purchaser rational, but also may lead to credit crunch, such drastic things themselves No one dry, unless he is stupid.
平头的人&硬生活甚至买房子&,他们不知道什么是&房地产泡沫&;专家和学者了解泡沫,根据中国的住房价格和居民收入的比例远远高于国际标准,有是的是空置率国际比较;但官员知道如何&泡沫&是什么意思,它从来不承认泡沫,一个是中国国情不同,中风和赢得100杆,是所谓的&国家是一个篮子里,有什么可安装在&第二,不同的统计数据,你有你的空置率,和我有我的空缺率,三说,即使有也是局部泡沫泡沫,不应除了所有;最乐观的房地产开发商,认为中国的房地产正处于快速发展阶段,没有泡沫的阴影中,最可信的,因为承认了泡沫,不仅意味着楼市即使不垮,将移交给买受人合理,而且还可能导致信贷紧缩,如此激烈的事情本身,没有人干的,除非他是愚蠢的。

The main contents are as follows:Firstly, starting with the general situation of soil erosion and the harms caused by it, the causes leading to the local soil erosion problem are analyzed comprehensively in the paper. And connecting with the measures taking place, sticking points towards the career of soil and water conservation are expatiated upon.Secondly, Back-Propagation Neural Network, One of Artificial Neural Network is used to set up a modal about the connection of the soil erosion modulus and seven factors impacts on it, such as, rainfall, rainfall largest intensity in 30 minutes, runoff coefficient, vegetation cover percent, rate of granule, rate of physical viscidity-clay, the rate of organic matter. Through the comparison with linear regression model, the second regression model, the Chinese Soil Loss Equation, it illustrated that BP Neural Network modal is more accurate than the other three modals in forecasting the mount of soil erosion, and the BP Neural Network will have some applicability in forecasting in soil erosion.
本文以霍山县作为皖西大别山区的典型区域,主要研究了以下内容:(1)从介绍霍山县土壤侵蚀状况以及所造成的危害入手,全面分析了导致当地土壤侵蚀发生的原因,并结合当地采取的水土保持相关措施,阐述了当地水土保持工作的症结所在;(2)结合上土市水土保持试验站多年实测资料和2005年实验资料,应用BP神经网络理论,建立了次降雨土壤侵蚀量与次降雨量、最大30min雨强、径流系数、植被覆盖度等因子之间关系的模型,并通过BP神经网络的预测模型与一次回归模型、二次回归模型、CSLE模型之间的对比分析,说明了建立的BP神经网络模型在土壤侵蚀预测可以取得较回归模型和CSLE模型更高的精度,也说明了BP神经网络理论在土壤侵蚀预报中具有一定的适用性。

Solani. The extract was further separated into two parts and one part separated by ethyl acetate while the other was separated by petroleum ether. Based on the inhibition experiment against R. solani, ethly acetate extract has a rather strong effect on R. solani with 89.70% inhibition rate and 15.52 mgmL^(-1) EC 50.The effect of petroleum ether extract on R. solani is relatively weak. The former was again divided into five parts in silica gel column, of which the second part significantly inhibits R. solani. During the periods of 24 and 48 hrs, the inhibition rate of the second part on R. solan is respectively 89.58% and 80.36%.
结果表明:鸭粪乙醇提取物对水稻纹枯病菌有抑制作用,24h内最高菌丝生长抑制率和EC50分别为88.64%、26.11mgmL^(-1);鸭粪乙醇提取物经萃取分离得到石油醚和乙酸乙酯两种组分,其中石油醚组分抑菌效果较弱,乙酸乙酯组分抑菌能力较强,其对水稻纹枯病菌抑制率为89.70%,EC50为15.52mgmL^(-1);对乙酸乙酯组分进行硅胶柱层析分离得到5种流份,其中第2流份有显著抑菌活性,在24h和48h内对水稻纹枯病菌的抑制率分别为89.58%和80.36%。
