摘要
研究了不同海拔高度、坡向、坡位、坡形等因素以及相同坡向、坡位与海拔高度对小油桐结实的影响情况,结果表明,当植株生长处在海拔500~550m时,居于同一坡位中部和中上部、非山洼地形条件且坡向为120~240°条件下,植株长势较好、结实早、果实饱满、结实量较稳定。
Study was conducted on effect of altitudes, slope aspect, site and slope shape on seeding of Jatropha curcas. Discussion was made on the relationship between slope aspect and site with altitudes. The result showed that it grows well with early seed bearing, stable seed yield at elevation of 500-550 m, in the same middle and upper slope site under terrain conditions and aspect of 120° - 240°
