摘要
以哈尔滨市具有代表性的3种土质:黏土(A)、粉质黏土(B)、砂土(C)为基质,分别种植紫花苜蓿、小冠花和无芒雀麦3种草本植物。通过现地观测的方法得到各植物的高度、颜色、均一度、抗病性、抗旱性、抗贫瘠性等指标,分析不同土质对草本植物生长状态的影响,结果表明,紫花苜蓿在砂土土质上生长状态最好,在黏土土质上最差;小冠花在黏土土质上无论是生长速度还是抗逆性都好于其他两个样方;无芒雀麦则是在粉质黏土土质上有最好的生长状态。
An experiment was conducted to plant Medicago sativa, Coronilla varia, and Bromus inermis in three representative soils （clay, silty clay and sandy soil） in Harbin. Height, color, evenness, disease resistance, drought resistance, and barren resistance of the three species of plants were observed. The influence of different soil textures on plant growth was analyzed. Results show that M. sativa plants grow best in sandy soil and worst in clay. C. varia plants grow best in clay, with higher growth rate and better resistances. B. inermis plants grow best in silty clay.
