麻疯树丰产栽培关键技术研究

Study on High Yield Cultivation Key Technique of Jatropha curcas L.

[目的]研究麻疯树丰产栽培关键技术,推动麻疯树产业的健康发展。[方法]以2年生麻疯树为试材,通过改变麻疯树种植密度,进行整形修剪,施用外源激素处理的方法研究其丰产栽培关键技术。[结果]种植密度为2.0 m×3.0 m的处理,产量、含油量有大幅度提高;整形修剪能够提高1倍的产量;多效唑能够提高其结果数、果实饱满度、出籽率以及产量。[结论]麻疯树种植密度2.0 m×3.0 m较好,整形修剪时保留14-16个强壮的分枝为最佳,外源激素处理以多效唑处理效果最好。

[Objective] The aim was to study high yield cultivation key technique of Jatropha curcas L..[Methods] 2-year-old Jatropha curcas L.were used as testing materials,through changing planting density of Jatropha curcas L.and pruning were carried out,exogenous hormone treatment were applied to study high yield cultivation key technique of Jatropha curcas L..[Result] The treatment of planting density with 2 m × 3 m can improve the output and oil content;pruning can be improve the output double;paclobutrazol can improve fruit number,plumpness of fruits,seed ratio and output.[Conclusion] Planting density with 2 m × 3 m was better,retaining 14-16 stronger branches when pruning were best,the effect of paclobutrazol dispose among exogenous hormone dispose was better.
