近年来，平菇生产发展很快，多以棉籽壳为培养料，这样，棉籽壳就十分紧缺，于是，许多人研究以玉米芯（秸），稻草、甘蔗渣乃至野草为培养料栽培平菇。本试验以豆秸秕谷为培养料栽培平菇，获得成功，具体单位、个人可按此法栽培。 相似文献

以醋糟为培养料,进行了平菇栽培试验并筛选出合适的平菇菌种。试验结果表明:利用醋糟代替棉籽壳栽培平菇是可行的,其适宜的平菇菌种为 F3、PL-31和 R-378,相应的生物学效率为91.6％、88.6％和76.6％。 相似文献

近二年来,生料袋栽平菇在承德市郊区及承德县发展很快,其中有些农户栽培失败,损失很大。1992年秋末冬初,笔者对承德市郊区的双滦区一带及红石砬沟一带的平菇生产做了初步调查,结果是:双滦区1992年5月购进棉籽壳30吨,有13户采用棉籽壳为原料进行生料袋栽平菇生产,其中6户属于自己家庭自制菌种用于栽培,结果全部失败,这6户共用棉籽壳17.5吨,初步统计各种原材料费用损失达13000元以上;红石砬沟有10户以高粱壳为原料进行生料袋栽平菇生产,这10户属于外购菌种进行栽培,也全部失败,初步统计这10户的各种原材料费用损失达12000元以上。试以两户为例进行剖析,分析其失败原因。 相似文献

栗蒲壳营养丰富,吸水性强,透气性好,粉碎后可以作为平菇生产的培养料,按栗蒲壳50％、棉籽壳25％、锯木屑25％混合成培养料生产平菇,则平菇的生产成本低、效益高。 相似文献

笔用蔬菜老茎叶、瓜果皮、中药渣等培养平菇，生物学效率达80．17％，采收的平菇实体肥厚，其中可溶性蛋白含量333．585mg/g干重；SOD活力单位17521U／g干重，均高于棉籽壳培养的平菇，为确保所产平菇的食用安全，决不能用霉变的植物性垃圾，同时应配适量玉米粉、米糠等辅料，以补充营养基的氮素营养。 相似文献

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity. 相似文献

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F. 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

Different nations have different social cultures, and the social culture of every nation is developing with the development of the nation, language is greatly influenced by social culture, which enables language to possess national and historical characteristics. Word is the smallest, independent, meaningful linguistic unit of language. It can well reflect the national and historical characteristics. From synchronic aspect, the social and cultural influence on word meaning is mainly embodied in conceptual and associative meanings of word. The incorrespondence of word meaning is a phenomenon that exists in both conceptual and associative meanings of word among different languages. From diachronic aspect, the development of social culture causes some changes of word meaning to some extent. Therefore, social culture plays a key role in vocabulary learning and mastery of a language. 相似文献

汉字的六书,《说文》对“转注”一类,语焉不详。后世学者提及转注,也仅限于许慎所举出的例字。《汉字例说》一文,作者从转注的角度综合考虑,对部分现代常用字作了分析,跟传统的解释有所不同。希望能抛砖引玉,互相切磋,以推进学术研究。 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献
