摘要: 通过多年的调查和监测,认为白于山山区仁用杏生产中存在的主要问题是花期、幼果期霜冻频繁;主栽品种为龙王帽,开花早,花期短,不抗霜冻;园址以南坡为主,开花较其它坡向早,易遭霜冻,不易坐果。由于仁用杏的产量不稳定,经济产值低,造成仁用杏园遭到砍伐或荒芜。提出该区应积极选育、引进抗霜冻品种和晚开花品种,加强仁用杏园的管理、改造,积极发展山杏、山桃,弥补仁用杏生产中的不足。

Abstract: On the basis of many years investigations and observations, the main problems of almond-apricot production in Baiyushan mountainous area of northern Shaanxi have been unveiled. Almond-apricot florescence and fruiting phase encounters strong and much frost. Chief variety of almond-apricot is Longwangmao, but Longwangmao florescence is shorter and earlier than other varieties, and resists frost weakly. Most almond-apricot have been planted on southern slope land, the tree on southern slope land blossoms earlier than other direction slope land, so has more chance of encounter frost, this not benefit for fruiting. On account of low yield and low production value, many almond-apricot trees have been cut down or have been desolated. Baiyushan mountainous area need select and introduce resistant frost varieties and late blossom varieties, strengthen administration and alteration almond-apricot production, develop wild apricot and wild peach, and offset the damnification of almond-apricot.
