对陇南市栽植的“清香”、“香玲”、“强特勒”3个主栽品种不同采收期含油率进行测定与分析。结果表明,含油率的变化随果实成熟呈现出由低到高的趋势,果实成熟时最高,过熟后有降低趋势,因此可以确定在最佳采收期核桃的含油率最高。3个品种含油率比较可得“强特勒”>“清香”>“香玲”。据此提出了陇南核桃优质丰产栽培技术的几点建议。 The oil recovery rates of three main cultivars cultivated in Longnan, such as “sweet fragrance”, “Hong Ling” and “Strongler”, were measured and analyzed. The results showed that the change of oil content showed a trend from low to high with the ripening of fruit, the highest when ripening and the decreasing trend after ripening. Therefore, it was concluded that the walnut with the best oil recovery rate had the highest oil content. 3 varieties of oil content is more available “Strongler ”> “fragrance ”> “Hong Ling ”. Based on this, some suggestions on the cultivation techniques of high quality and high yield of walnut in Longnan were put forward.
