摘  要:
本文以森林苗圃中常见的重壤土、轻壤土、沙壤土为研究对象,分析测定了与土壤水分有密切关系的土壤塑性限、塑性上限、粘点、塑性系数等物理机械性状,用塑性限作为土壤耕作的最高含水量指标。提出了合理耕作、休闲轮作、增施有机肥等土壤团粒结构管理技术措施。

摘  要:
The research into heavy loam,light loam and sandy loam(which taken from the forest nursery of Tahe(Forest) Bureau,Heilongjiang Province,China)analyzed some physical properties of the soil such as plasticity limit,the upper limit,viscosity number and plasticity coefficient,and regard plasticity limit as the highest index of moisture(content.) This paper gives an introduction on how to manage soil granular structure in reasonable farming,crop(rotating,) organic fertilizer application etc.It would provide a basis theory and practice for cultivating high-quality(seedlings.)
