为节省红麻生产成本，提高种植效益，本试验以水稻-红麻轮作地为研究对象，研究免耕与翻耕对土壤理化性状和红麻生长的影响。结果表明：苗期时，免耕与翻耕的3级根数差异显著，免耕多，分别为737.80条和584.80条；免耕与翻耕的单株根、茎、叶的鲜重和干重同样存在显著性差异，均是免耕的重，免耕与翻耕的单株干生物产量差异极著性，分别为3.34 g和1.92 g。免耕与翻耕的土壤容重差异显著，其均值分别为1.3354 g/cm3和1.1888 g/cm3。免耕的土壤水分含量总体呈下降趋势，翻耕的土壤水分含量呈上升趋势，但免耕与翻耕的均值无显著性差异，分别为33.24％、32.43％。免耕与翻耕在不同时期、平均值的土壤孔隙度差异显著，其中它们均值分别为49.61％、55.14％。免耕与翻耕的小区干皮重差异极显著，分别为5.79 kg、5.29 kg。

To save the production cost and improve the planting efficiency of kenaf , a rice-kenaf rotation field was chosen as experimental field to study the different infuence of tillage and non -tillage on soil properties and crop growth.The results showed that the root number of grade 3 during seedling stage had a significant difference between non -tillage and tillage , the roots of non-tillage were 737.80 and of tillage were 584.80 respectively.Moreover, fresh weight and dry weight per plant root , stem, and leaf also existed significantly different between non -tillage and tillage.The dry weight of non -tillage was heavier.Furthermore, the dry biological yield per plant had a significant difference between non -tillage and tillage , and the weight was 3.34 g and 1.92 g respectively.Soil bulk density had a significant difference between non -tillage and tillage as well , the average values were 1.3354 g/cm3 and 1.1888 g/cm3 respectively.In general, non-tillage soil moisture content was on the decline , tillage soil moisture content was on the increase , but the average value of non -tillage and tillage had no significant differ-ence, they were 33.24%and 32.43% respectively.During different periods , the average value of soil porosity had a significant difference , the average values were 49.61% and 55.14% respectively.Dry bark of plots had a significant difference between non -tillage and tillage , the weights were 5.79 kg and 5.29 kg respectively.
