为了在多雨山地环境中实现果园大面积丰产,从1983年起,我们在四川省凉山州荞窝农场云盘山中队,对400亩苹果幼树园进行了早结、丰产栽培技术的研究,并初步摸索出一些可行的技术措施。一、土、肥、水的管理: 1、土壤的熟化改造。试验园大部分苗木是1980年直接定植在刚推出的台土上,土层瘠薄,有机质含量低,加之缺肥缺人,管理粗放,苗木生长差,呈现出明
In order to achieve large-scale orchards yielding in rainy and mountainous environments, starting from 1983, we conducted a research on early-maturing and high-yielding cultivation techniques for 400 mu of apple tree saplings at Yunpan Mountain Squash Farm in Liangshan Prefecture, Sichuan Province, Explore some feasible technical measures. First, soil, fertilizer, water management: 1, soil aging transformation. Most of the seedlings in the test garden were planted directly on the terrace soil just launched in 1980. The soil layer is infertile with low organic matter content. In addition, the shortage of manure, extensive management, poor seedling growth,
