地木耳对环境因子的响应研究

Response of Nostoc Commune to Environmental Factors

指出了环境因子是生命活动的重要限制因子,对生物有机体的生长发育和生理代谢具有明显的影响。对地木耳生长的环境和其分布区土壤pH值、有机质、全氮、全磷、速效磷和速效钾含量进行了研究,结果表明:地木耳适宜生存于温度和湿度较高、通气性较差的微环境中,其生长需要充足的水分,但不宜水渍;地木耳对土壤质地无特殊要求,适宜在中性至酸性和有机质含量较高的土壤中生长,而对土壤全氮、全磷、速效磷和速效钾的含量则无特殊要求。

The environmental factors are the vital limiting factors for life activities, and have obvious influences on the growth of biological organism and physiological metabolic of living organisms. This article studies the growth environment of Nostoc commune and the soil pH value, the organic matter, the entire nitrogen, the entire phosphorous, the available phosphorus and the available potassium of Nostoc commune＇s distribution area. The results show that Nostoe commune is suitable to survive in the micro environment with high temperature and humidity and poor ventilation, and its growth needs sufficient moisture content but cannot be waterlogged. The Nostoc commune adapts to growing in the neutrality to the acidity and the high organic soil content and has no special requirements on the soil texture and the entire nitrogen, entire phosphorus, available phosphorus and potassium content of the soil.
