我省在山地杉木造林中的整地方式,根据各地区的习惯,大体上多采用小穴、块状、水平带状和全垦等几种整地方式。这几种整地方式对杉木幼林生长有不同的影响,在生产实践中是明显存在的,也为大家所认识到的。但是,这几种整地方式对幼林生长影响的程度,对林地土壤营养状况的作用及其经济效果等等的综合影响,尚缺乏全面的评价。因此,在生产实践上往往容易产生片面地推广某种整地方式的倾向,带有一定的盲目性。为了克服这一倾向,并研究在山地条件下具有促进林木生长、改良土壤和节省整地用工的整地方式,我们于1975年春季在新干县城上公社江上大队林场进行了山地杉木造林整地方式试验。现将三年来的试验结果整理如下。
In our province, the site preparation method of afforestation in mountainous area is based on the habits of different regions. Generally, we use the method of site preparation such as small hole, block, horizontal strip and full planting. These kinds of land preparation methods have different effects on the growth of young Chinese fir plantations, which are obvious in production practice and are also recognized by everyone. However, there is no comprehensive evaluation of the impact of these land preparation methods on the growth of young forests, their effects on soil nutrient status and their economic effects. Therefore, in production practice tend to produce a one-sided promotion of certain types of land preparation tendencies, with a certain degree of blindness. In order to overcome this tendency and to study the land preparation methods for forest tree growth, soil improvement and land-saving work under mountainous conditions, we carried out the experiment of afforestation and site preparation for the afforestation of the mountainous area in the spring of 1975 in Xinjian County commune Jiangshang Daping Forest Farm. Now three years of test results are summarized below.
