我们在取得丘陵撩壕种杉,6—8年成材的初步成果后,反骄破满,继续前进。近几年又在向阳、干旱瘠薄光秃的丘陵岗上栽植102亩杉树,幼树茁壮,长势喜人。其中2亩是1972年2月撩壕栽植,加罩抚育的幼林,现树高已达188厘米,根径5.1厘米,比单撩壕不加罩抚育的对照树,高、径生长快1倍。另有100亩是在1973年1月撩壕种植,加罩抚育的,现树高95厘米,根径1.4厘米,也比对照树高径生长快0.5—1倍(见表1)。
After we achieved the first results of the hilly fir plantation and the successful harvest of 6-8 years, we continued to move forward with anti-arrogance. In recent years, it has also planted 102 acres of cedar trees in sunny and arid barren bare hills and hills, and the young trees are thriving and growing favorably. 2 acres of which were planted in February 1972 and covered with tending young trees. The tree height now stands at 188 centimeters and the root diameter is 5.1 centimeters, which is twice as high as that of the control tree with single trenches and no hood tending . Another 100 mu was planted in trenches in January 1973 and covered with tents. The height of the tree is 95 cm and the root diameter is 1.4 cm. It is also 0.5-1 times faster than that of the control tree (Table 1).
