摘要
对麻疯树进行育苗试验，采用播种育苗、扦插育苗、埋杆育苗三种繁殖方式，以播种育苗较好。通过设置固定样方定株进行观察，分析麻疯树地上部分（苗高、地径）生长和地下部分生长（根系）。麻疯树苗期侧根不明显，地上部分高径比为埋杆〉扦插〉播种。探索三种留床密度，得出每平方米按30-35株留床密度最佳，苗木长势较好，均匀，分化较少。分析无性繁殖机理，麻疯树为愈伤组织生根。进行二个肥种初步试验，结果表明：灶灰施肥效果较好。
Three techniques （seed, cutting〉 burying） for the seedling cultivation of Jatropha curas L. were tested, and the result showed that the seed propagation has the best result. Based on the measurement and analysis of the above-ground and below-ground part of the seedlings in the fixed plots, it concluded that the lateral root of the seedlings is not well-developed and the height-diameter ratio of the seedlings has an order of burying 〉cutting〉 seed. The best seedling density is 30-35 plants /m^2 . The effect of the fertilization for the growth of the seedlings is also obvious.
