为进一步探索乔木桑栽培技术,不断提高科学管理水平,近两年我们对乔木桑“定干”、“修剪”、“采叶”等项目作了培管试验,并取得一定成效,现整理简报如下:定干试验一、试验方法1.树龄选择:5年生集体渠道乔木桑.2.定干时间及高度:1979年冬,结合整枝修剪,按主干高度4米进行定干.3.试验株数:试验区和对照区各10株,其立地条件、肥培管理及采叶程度均相同.
In order to further explore the technology of arborvitae mulberry cultivation and continuously improve the scientific management level, we have carried out experiments on the cultivation of Arborvitae “dried root”, “pruning” and “picking the leaves” for the past two years and achieved some success. As follows: dry test First, the test method 1. Tree age selection: 5-year-old collective channel arborvitae Mori .2 dry set time and height: the winter of 1979, combined with pruning pruning, according to the trunk height of 4 m dry .3 test number : The experimental area and the control area of 10, the site conditions, fertilizer management and harvesting degree are the same.
