摘  要：
对松嫩草地不同生长时期的6种牧草的可溶性糖、粗脂肪、纤维素含量及其相应生长地土壤理化因子进行了研究,结果表明土壤的有机质含量、全氮含量的提高有利于植物养分含量的积累,而 pH的提高和 Na~+和 HCO_3~-含量的增加则对植物养分含量的积累有抑制作用。但各种土壤理化因子对不同植物养分积累的作用是不同的,鹅茸萎菱菜的生长地土壤比较肥活,土壤理化因子对其养分积累影响不大;土壤 K~+含量对星星草可溶性糖的积累起主要作用;pH 是蔓萎菱菜养分积累的限制因子;针茅的纤维素含量受土壤理化因子的影响不大;羊草的粗脂肪含量与土壤 K~+含量呈正相关;碱蒿的养分含量受土壤理化因子的影响最明显,土壤中有机质、全氮和 K~+的下降,pH、Na~+和HCO_3~-含量的升高均可使碱蒿养分含量下降。

摘  要：
This paper studied the soluble sugar,raw fats and cellulosecontent of six herbage on Songnen grassland,and we also studied the physical and chemical factors o the soil which the herbage lived on.The results indicated that the increase of organic matter content,total nitrogen content of the soil contribute to the nutrient accumulation of plants,but the increase of pH and the content of Na~+ or HCO_3~- of the soil check the nutrient accumulation of plants.But the fuction of variors physical or chemical factors of the soil is different to the nutrient accumulation of each plant:Potentilla anserial lived on the rich soil,the physical or chemical factors of the soil have a little effect on its nutrient accumulation;the contentof K~+ of the soil is the main factor for the accumulation of soluble sugar of Puccinellia tenuiflora;the pH value is the restricted factor for the nutrient accumulation of Potentilla flagellaris;the physical and chemical factorsof the soil have a little effect on the content of cellulose of Stipa;raw fats of Aneurodepidum chinese is positive correlated to the content of K~+ of the soil;the physical and chemical factors have the distinct effect on the nutrient accumulation of Artemisia anethuiflia Weber,With the decrease of the content of organic matter,total nitrogen and K~+ and increase of pH,Na~+ and HCO_3~- content of the soil,the mutrient content of Artemisia anethuiflia Weber isdecreased.
