摘要
本文分析土壤质地、表土层厚度、全氮、全磷、速效氮、速效钾、有机质含量对杉木种子败育的影响,根据数量化模型Ⅰ,建立败育种子(涩粒和空粒)的预测模型,并指出引起种子败育的主导因子。
In this paper, the relationships between chinese fir sterile seed and soil texture, thickness of surface soil overall nitrogen, overall phosphrous, available nitrogen(N),abailable potassium and organic material were analysed, at the same time, the forecasting model of quantity chinese fir sterile seed was pointed out through applying the quantatitive theory I.
