查询词典 biomass

According to the absolute value of the coefficient in 3 the principal components,Marmot habitat selection'main factors were elevation、slope gradient、longitude(the absolute value of the coefficient respective were:0.860、0.740、0.712)and so on geography factor.Vegetation height and aboveground biomass have synergistic effect with geography factor.Distance from human disturbance and distance from road(the absolute value of the coefficient respective were:0.814 and 0.820) human activity factor were secondary factor.Vegetation coverage would named vegetation factor (the absolute value of the coefficient was:0.816) have very important influence to Marmota habitat selection.

根据三个主成分中载荷系数绝对值的大小可以判断影响旱獭生境选择的主要生态因子是海拔、坡度、纬度(载荷系数绝对值分别为：0.860、0.740、0.712)等地理因子，草高、地上生物量与地理因子又具有协同效应；距人为干扰距离、距公路距离(载荷系数绝对值分别为：0.814和0.820)人类活动因素是次要因子；盖度(载荷系数绝对值为：0.816)将其命名为植被因子，对旱獭的生境选择也具有重要的影响作用。

The results showed that: biomass in the Melilotus suaveolens is the highest in four green manure; after pressed four green manure in the Green the cotton fields, soil organic matter,nutrients are available certain influence; after Melilotus suaveolens and soybean pressed in the soil,organic matter increased by 8.58% and 1.01%;four green manure pressed in the soil available nitrogen increased by0.30%-5.96%,except soybean, the soil available potassium of the other three dealt is 1.08 times that of the control; the role of rich potassium in Rape and Oil sun flowers are even more significant .

研究结果表明：四种绿肥中草木樨的生物量最高；四种绿肥翻压后对土壤有机质和速效养分含量均有一定的影响，其中草木樨、大豆翻压后土壤有机质分别提高了8.58%，1.01%；四种绿肥翻压后土壤速效氮提高了0.30%-5.96%，除大豆外，其它三个处理的土壤速效钾含量平均是对照的1.08倍；研究发现油菜、油葵的富钾作用较为突出。
