摘要
通过实地调查,研究了立地条件对油茶病情指数的影响。结果表明:坡向对油茶病情指数有明显影响,其中阳坡最小为15,阴坡最大为29,半阴半阳坡介于二者之间;随着坡度的增大,油茶病害加重;山洼的油茶病情指数显著小于山脊和山坡。研究结果说明油茶适合栽培在坡度和缓、侵蚀作用弱的地方。
The influences of site conditions on disease index of Camellia oleifera Abel.have been studied by field investigation.The results show that slope direction has obviously influenced the disease index of Camellia oleifera Abel.,with the minimum value of 15 at sunny slope,the maximum value of 29 at shady slope,and the middle value at half-sunny-half-shady slope.The disease of Camellia oleifera Abel.becomes seriously with the increase of slope.The disease index of Camellia oleifera Abel.in gap is smaller than the one in ridge and slope.Camellia oleifera Abel.is suitable to be planted in gentle slope with weak erosion.
