“核桃是重要的木本油料和用材树种之一,在国民经济建设和人民生活中占有重要位置。目前,甘肃陇南市康县共有核桃树600多万株,其中结果树280多万株,平均单株产量只有1.5kg左右。除病虫害、气候等其它因素影响外,核桃树修剪技术不能全面的得到应用,亦是造成低产的重要原因之一。在示范性实践中我们通过加强对核桃树各个时期的修剪,有效解决了大树产低质差的问题,同时经过对幼树实施整形修剪,使其提早挂果增加产量,取得了显著成效。加之它投资小、见效快,易被广大群众所接受。基于此,根据甘肃陇南市康县核桃生长情况和当地雨量多(807mm),湿度大,日照时间较短(1715.7h日照率39%)等实际情况,结合多年来的实践操作经验,提出如下修剪意见供参考。
”Walnut is one of the important woody oilseeds and timber species, occupies an important position in the national economy and people’s lives.Currently, there are about 6,000,000 walnut trees in Kangxian County, Longnan City, Gansu Province, of which more than 2.8 million trees are the result trees, The average yield per plant is only about 1.5kg.In addition to pests and diseases, climate and other factors, the walnut tree pruning technology can not be fully applied, is also one of the important reasons for low yield.In the example of our practice by strengthening the walnut tree Pruning in various periods effectively solved the problem of low quality and poor quality of large tree production. At the same time, it achieved remarkable results through plastic pruning of sapling so as to increase its output ahead of time. In addition, with its small investment and quick returns, Based on the actual situation of walnut growth and local rainfall (807mm), humidity, shorter sunshine duration (39% sunshine rate at 1715.7h) in Kangxian County, Longnan City, Gansu Province, combined with many years of practical operating experience, Proposed the following pruning advice for reference.
