在毛主席“绿化祖国”的伟大号召下,怀集县林科所广大革命职工,对杉木速生丰产技术进行了研究,经过反复地实践,总结出了“撩壕”整地培育杉木速生丰产林的好方法。一、“撩壕”造林的方法按等高线挖长坑,去心土后填入表土的造林方法叫做“撩壕”造林。坑沟宽0.67米,深0.5米,长数丈的叫做“大撩壕”;坑沟宽0.5米,深0.33米,长数丈的叫“小撩壕”。挖坑先从山下挖起,把黄泥放在沟下边,按规格挖好后,将沟上边的表土产入沟内填满。完工后按一定距离再挖一条,方法同上。挖壕过程中,将清除的石头黄泥放在沟间,防止杂草蔓生,
Under the great call of Chairman Mao’s “greening the motherland,” the vast number of revolutionary workers in the Forestry Branch of Huaiji County studied the fast-growing and high-yielding techniques of Chinese fir plant. After repeated practice, they concluded that the cultivation of fast-growing and high-yield fir plantation good idea. First, the “trench” method of afforestation Digging according to contour pit, to heart soil after the topsoil afforestation method called “pull trench” afforestation. Hang ditch width 0.67 meters, 0.5 meters deep, Zhang Shu long husband called “big trenches”; pit ditch 0.5 meters wide, 0.33 meters deep, long husband called “small trenches.” Dug digging from the foot of the mountain, put the yellow mud under the ditch, digging according to specifications, the ditch above the topsoil into the ditch to fill. Completed by digging a certain distance, the method Ibid. Digging process, the yellow mud will be placed in the ditch to prevent the weeds from spreading,
