松花江母亲河岁月·梦想与现实(上)

沿着松花江母亲河一路走访,望着她的涛涌流奔的雄浑与美丽,我愿用心底的声音呐喊:松花江,我们北方民族的母亲河,我们热爱你!这种热爱不是空泛的,而是实实在在的,有七千万母亲河流域的儿女们作证,更有她周遭的青山、绿树、草原和湿地作证。儿女们的繁衍剧增,过多地消耗着母亲河的资源,以至于让今天的母亲河不时发出伤痛与叹息。可历史上的松花江,却以其无比的美丽、优渥而令人神往啊!现在让我剪取松花江母亲河历史上的几个镜头,用散点透视的方法,来看一看松花江历史上的容颜与魅力吧……与中原大地神脉相通的松花江上古时,帝舜有虞氏二十五年…     

松花江母亲河岁月·梦想与现实(下)

牵动人心的松花江松花江水系哺育了四大片森林:长白山森林、小兴安岭森林、大兴安岭森林和张广才岭森林。这四大片森林是中国东北疆的肺叶,也是松花江流域水量均衡、水土保护向优良方向转化的天然调节水库。全东北的地形宛若一个浅簸箕,由大、小兴安岭、完达山、长白山镶边,张广才岭与吉林哈达岭及其森林犹如簸箕底上的两条横向的凸起,而江川河溪,就是它横亘的筋络。这种特定的地形,造成了辽河向南注入渤海,以及松花江干流最后朝东北流,同黑龙江相会,再同乌苏里江相会而北流注入鞑靼海峡——鄂霍次克海的流向。从日本海吹来的风和从西伯利亚…

The Swedish matsutake (Tricholoma nauseosum syn. T. matsutake): Distribution,Abundance and Ecology

The commercially important mushroom matsutake has been considered uncommon in Sweden by most mycologists and has been unknown to the Swedish public. Between 1849 and 1997, 81 matsutake reports were registered in Sweden. A field study in 1998 resulted in 121 matsutake localities, of which at least 30% were prolific, producing 30-200 fruit bodies ha^-1 in the far north of Sweden. Using DNA sequencing of rDNA internal transcribed spacer (ITS) it was shown that Japanese and Swedish matsutake (Tricholoma matsutake and T. nauseosum) should be treated as the same species. The oldest name is T. nauseosum, but it is suggested that the name T. matsutake should be conserved. This study has stimulated private companies to investigate possibilities for commercial export to Japan.     

Dieback Disease of Pines with Special Reference to Corsican Pine Pinus nigra var. Calabrica Schn.: II. The Relationship between Frost Resistance, Microclimate, and.Disease

The winter frost hardiness level of Corsican Pine buds in northernEngland is found to range from –16° C to –20C (+3° F to –4° F). Buds in the lower parts ofthe tree are more susceptible to frost damage than those nearerthe leader, and buds at a given position in the canopy on anorth-facing slope are less hardy than those in a correspondingposition on a tree in a south aspect. The symptoms produced by artificial freezing are distinct fromthose found in dieback disease, and temperature measurementsin diseased and healthy stands suggest that frosts are not severeenough to account for the disease. The lower hardiness levelsin disease susceptible areas are therefore considered to beof secondary importance and are probably a result of a weakenedphysiological condition in the tree. Diseased slopes are chiefly characterized by high humidities,low light intensities, and only slightly reduced air and soiltemperatures when compared with nearby healthy areas.
