Relationships between soil and vegetation characteristics of tundra ecosystems and their use to assess soil resilience, degradation, and rehabilitation potentials     

V. D. Vasil’evskaya  V. Ya. Grigor’ev  E. A. Pogozheva 《Eurasian Soil Science》2006,39(3):314-323

Definitions of the notions of soil resilience and degradation of the soil-vegetation cover are suggested. These problems are considered with respect to vulnerable tundra ecosystems. The analysis of available experimental data made it possible to obtain empirical equations characterizing the relationships between the plant productivity and the soil properties. These equations can be used to predict the degree of soil degradation under particular types of technogenic loads and the soil and vegetation potential for the natural restoration or artificial rehabilitation of the soil-vegetation cover in tundra ecosystems. The results obtained can be applied for the development of optimal nature management strategies in the areas of oil and gas fields in the north.  相似文献   

饲粮粗蛋白质、能量水平对3岁梅花公鹿鹿茸生长和体增重的影响   总被引：3，自引：0，他引：3  

高秀华  金顺丹  王峰  张学文  王晓伟  李忠宽 《经济动物学报》2002,6(1):5-8

为探讨 3岁梅花鹿生茸期饲粮适宜营养水平 ,本研究采用 2 (CP∶2 1%和 19% )× 2 (GE∶16 74MJ/kg和 15 90MJ/kg)二因子交叉设计 ,选用 3岁 (二锯 )梅花公鹿 6 7头 ,分为 4个试验组 ,进行了饲养试验和消化试验。试验结果表明 ,饲粮蛋白质水平对鹿体增重有显著影响 (P <0 0 5 ) ,在本试验所设能量浓度范围内 ,饲粮蛋白质水平为 19%处理组鹿体增重显著高于 2 1%蛋白组 ;鹿茸产量组间差异不显著 (P >0 0 5 ) ;饲粮粗蛋白质水平对蛋白质消化率和能量消化率均有显著影响 (P <0 0 5 ) ;3岁梅花鹿生茸期饲粮中能量、蛋白质适宜水平分别为 15 9～ 16 7MJ/kg (GE)和 19% (CP) ;平均每头鹿每天对消化能和可消化蛋白质的需要量分别为 2 9 9～ 31 3MJ和 388～ 394 g。  相似文献   

产房内仔猪腹泻的原因及防治措施     

李成  单瑛琦  李东 《饲料广角》2009,(12)

仔猪腹泻是目前规模化养猪生产中最严重的仔猪疾病之一.产房内仔猪发生腹泻后,轻者可使患病仔猪体质下降和免疫功能减退从而导致其对其他疾病的抵抗力减弱,严重者可引起仔猪死亡,给养猪生产造成严重经济损失.  相似文献

Diurnal and seasonal occurrence,feeding habits and mating behavior ofMaladera matrida adults in Israel     

Alla M. Gol’Berg  Shoshana Yathom  Ahuva ALmogi-Labin  G. Fridland-Wunder 《Phytoparasitica》1989,17(2):81-89

Adult populations ofMaladera matrida Argaman (Coleoptera: Scarabaeidae), a beetle highly injurious to agricultural crops, were studied in the coastal plain of Israel from 1985 to 1988. There were two generations annually. Adults emerged in March, April or May and disappeared in October or November. The beetles are on the wing, mate, and feed at twilight and in the dark. Feeding and mating behavior, sex ratio, and preferred food plants were studied.  相似文献
