培植大支头高档人参的关键技术

本文对培植大支头高档人参的几点关键技术进行了阐述,认为掌握人参的几个重要生物学特性,抓住“温、光、水、肥”四个因子的人为管理,是可行的。

培育大支头人参技术要点

通过对吉林省集安、抚松、长白、靖宇等主产参区的调查,现提出培育大支头人参的技术要点。1 使用“隔年土”在栽种人参前一年翻耕晾晒的栽参备用土称为“隔年土”。用“隔年土”栽参是确保人参优质高产的先决条件。因为经过冬春的冻融交替和风吹日晒雨淋,能充分熟化。

今日(10月16日)安国药市行情点评

安国药市,天高云淡,阳光明媚,金风飒飒,市场平静,仿佛狂欢夜之后宁静的清晨。安国药商,心态如秋景,少一点浮躁多一分沉稳,少一点盲从多一分理智,少一点消沉多一分大决战前的运筹帷幄。 中药材大品种多数处于市价的低谷期。三七、当归、川芎、麦冬、元胡、白术、玄参、生地、牛膝、黄芪、红花、云木香、桔梗、丹皮、黄柏、杜仲、厚朴大致可以归为一类。有人说它们进入了寒风刺骨的冬季,有人说,冬天来了春天还远吗? 涨跌的龙头品种白术,以及元胡、玄参,仿佛是困于陷井中的猛虎,不管如何咆哮也难于跃上山岭,估计两年左右市价在低谷中跳动。

今日11月16日广州清平药市行情

步入11月,广州药材市场不冷也不热,成交多是零星或小批量。居多药材经营者叫苦不迭,生意难做。近期生草药类及子仁类药材上市量有增无减,价格降多升少,动物类药材多走畅,价格升多降少。山萸肉新货陆续登场,每公斤(下同)

西洋参“空气整根”育苗试验的初报

“空气整根”技术是种植业的一项增产新措施,用于西洋参的育苗中,可培育出大支头、短主根的栽苗,为大批量生产大支头、短主根优质西洋参创造了先决条件。

Changes of macromolecular organizations in nonjunctional sarcolemmas after cross-innervation──a study offast-and slow-twitch muscle fibres in rats

The purpose of the present study was to analyse the changes of macromolecular organizations in nonjunctional sarcolemmas of different types of skeletal muscle fibres after cross-innervation. In normal rats the mean density of square arrays (6 nm particles organized in orthogonal arrays) was 9.02/μm2 for the nonjunctional sarcolemmas of fast-twitch extensor digitorum longus (control EDL,CE) nuscle fibres and 0.34/μm2 for the nonjunctional sarcolemmas of slow-twitch soleus (control SOL, CS) muscle fibres. After cross-innervation between the fast-twitch EDL and slow-twitch SOL muscle fibres by slow and fast muscle merves respectively for three months, the mean density was 0.45/μm2 for the nonjunetional sarcolemmas of the operated-EDL (OE) and 8.3/μm2 for the nonjunctional sarcolemmas of the operated SOL (OS). This indicates that the cross-innervation causes a reciprocal transformation of the number and distribution of such macromolecular organizations in the electrically excitable nonjunctional sarcolemmas.
