通过我所几年试验研究,红松山地育苗平均亩产成苗可达148千株,产苗量比平地苗圃提高215%,苗木质量也优于平地苗。千株成本近4元,比平地苗成本下降76%。现将研究结果整理分析如下: 一、试验地自然概况本项研究先后在桓仁县八里甸子公社大南沟大队和本溪县草河口公社茳草大队进行。八里甸子公社总的特点是:山高林密气温低,位于东经124°43′～125°07′,北纬41°10′～41°20′,海拔高为500～1300米,年降水量904.1毫米,无霜期128.5天。草河口四周皆山,山
Through several years of experimental research, the average yield per mu of seedlings in Hongsong Mountain can reach 148 thousand. The yield of seedlings is 215% higher than that of the nursery in the plain. The quality of the seedlings is also better than that of the flat seedlings. One thousand costs nearly 4 yuan, 76% lower than the cost of flat seedlings. The results of the study are summarized as follows: First, the experimental nature of the study This study has Habitat in Huanren County Dalian ditch Brigade and Benxi County Caohekou grasshopper Brigade conducted. The general characteristics of the Belitung Sub-commune are as follows: The mountain high forest is characterized by its densely-brained tempera- ture and low temperature, located between 124 ° 43 ’~ 125 ° 07’ east longitude and 41 ° 10 ’~ 41 ° 20’ north latitude with an altitude of 500 ~ 1300 meters and an annual rainfall of 904.1 mm , Frost-free period 128.5 days.
