山杏人工林丰产技术研究

本项研究，选择分布集中连片，立地条件典型、长势中等，具有广泛代表性并已开始进入结实期的人工山杏林为对象，以定位试验研究（随机区组试验和正交试验）为主，辅以区内外广泛深入的调查，应用先进的丰产技术措施达到提高结实量的目的。研究结果表明，山杏虽然耐干旱瘠薄，但对水、肥的反映相当敏感；尤其在半干旱地区，对水的依赖性更强。然而从目前的实际出发，本着立足于可能，欲实现丰产，应加强土壤管理和树体管理，采用封育

Study on High yielding Technology of Prunus armeniaca var. ansu Maxim Plantation

Prunus armeniaca var. ansu Maxim Plantation, which have typical site condition, medium growth vigor, close distribution, extensive representation, are selected as an object of study. This study put location test first while making extensive and thorough investigation. And the purpose to increase fruiting amount has been gained while applying advanced method of high yielding technology. The results show that Prunus armeniaca var. ansu Maxim make fairly sensitive reflection to water and fertilizer although they are able to bear drought and barrenness. It relies strongly on water especially in semi arid area. In order to achieve high yield, soil and tree management should be strengthened. And some comprehensive measures are adopted such as closing of forest area, enlarging hole and loosening soil, pruning, foliage spray, giving much chemicals, pest and insect control.
