我场位于安远县城郊北面,丘陵地区。自一九六三年办场以来,营造杉树四万六千余亩。为了摸索杉树幼林的抚育方法,我们进行了一些试验和调查,初步看出杉树全垦,深挖厚培表土是一种较好的抚育方法。全垦:坡度在十五度以下.全垦深挖五至六寸,大块翻转不打碎,效果很好。中坑五里排大路坎上一九七一年冬造林,原每年铲草一次,至一九七三年,平均树高仅1.96米,地经2.25厘米;年生长量高0.56米,地经0.76厘米。一九七三年采用全垦抚育一次,一九七四年
My field is located in the far north of Anyuan County, hilly areas. Since its establishment in 1963, it has built more than 46,000 Chinese fir trees. In order to explore the fir tree nurturing methods, we conducted a number of tests and surveys, initially see the cedar tree planting, dig thick thick topsoil is a better method of tending. Reclamation: the slope of fifteen degrees below the whole Ken deep dig five to six inches, large flip does not break, the effect is very good. In mid-pit Wuli platoon road ridge winter in 1971 reforestation, the original shovel once a year, to 1973, the average tree height of only 1.96 meters, 2.25 centimeters by; annual growth of 0.56 meters high, 0.76 cm. In 1973, it was nurtured once and for all in 1974
