济南南山核桃栽培现状及发展对策

Current Situation and Development Countermeasures of Walnut Cultivation in the Southern Mountain Area of Jinan

山东省济南市南部山区幅员广阔,地形复杂,核桃种植历史悠久,是山东核桃主产区之一。本研究通过实地调查发现南山核桃种质资源丰富,产业优势明显,但普遍存在结果晚、产量低、品质差、效益低等问题;分析其原因主要是实生栽培比重过大、栽植密度过大、管理技术相对落后等。根据南山核桃实际生产情况,提出了合理间伐、高接改优、加强管理等增产增效的技术措施,以期提升南山核桃产业发展潜力与空间,进一步促进南山核桃产业发展。

The southern mountain area of Jinan City,Shandong Province is one of the main production areas of walnut with rich land resources and long cultivation history.Through field investigation,we found abundant walnut germplasm resources endowed it with distinct walnut industry development advantage in the southern mountain area of Jinan.However,the problems of late fruiting,low yield,poor quality and low benefit were still existed commonly.These were mainly due to the large proportion of seedling cultivation,the high planting density,the relative backward management technology,and etc.According to the actual walnut production situation of the southern mountain area,we put forward some measures to improve the yield and benefit of walnut,including reasonable thinning,high grafting and strengthening management.It was expected to enhance the development potential and space and then further promote the development of walnut industry in the southern mountain area of Jinan City,Shandong Province.
