麻疯树采穗圃营建技术试验研究

通过正交试验设计研究麻疯树采穗母株不同定植株行距、截干高度和基肥施用对母株产穗量的影响;研究了麻疯树不同种源对母株产穗量的影响。结果表明,母树定植株行距A3（2.5 m×2.5 m）＋施用基肥B3（渣肥15kg和农家肥3 kg）＋母株截干高度C1（距根茎部位以上30 cm处）组合A3B3C1产穗量最高;麻疯树11个不同种源最优单株中,以05号种源产穗量最高。

Experimental Research on Establishment Technique for the Cuttings Orchard of Jatropha curcas

The orthogonal experiments were conducted on the row spacing of mother trees,different trunk-cutting heights and effects of different base fertilizers on the production of Jatropha curcas cuttings.The results showed that the combination of row spacing of mother trees at 2.5 m×2.5 m plus application of 15 kg of dregs and 3 kg of farmyard manure compound fertilizer plus the trunk-cutting height at 60 cm from the rootstock of the mother tree could yield best result,which could maximize the cutting production.No.05 provenance had the largest yield among 11 provenances of Jatropha curcas L.
