摘要
[目的]获得小桐子最佳的育苗密度。[方法]通过对在不同育苗密度下小桐子高生长、地径和分枝量的分析获得小桐子育苗的最佳密度。[结果]试验发现15cm×20cm为小桐子的最佳育苗密度,在最佳育苗密度下,小桐子平均每公顷出苗250005株,平均每公顷出优质苗160710株,出圃率为64.30%,平均育苗每株的成本为0.18元。
[Objective]The aim was to obtain the optimum seedling density of Jatropha curcas.[Method]The optimum seedling density was obtained by surveying the seedling height,ground diameter and shoot branching number of Jatropha curcas at different seedling densities.[Result]The optimum seedling density of Jatropha curcas was 15 cm×20 cm,at which 250 005 seedlings and 160 710 high quality seedlings emerged averagely every one hectare,emergence rate was 64.30% and average cost of was 0.18 yuan/seedling.
