杉木全光育苗,在土壤板结、透水性差、日照时间长、水源不足的情况下,干旱季节往往造成生长不良或大量死亡。如用荫棚遮荫,投资大,花工多。在毛主席“绿化祖国”的伟大指示指引下,自1974年以来,我们采用苗床侧方间种柽麻遮荫育苗,效果良好。当年生苗平均高29.04厘米,根茎0.57厘米,亩产苗7万株。其间种方法是:为增强遮荫效果,苗床作成南北向。4月上、中旬,在苗床的西、南两侧(床高1/3 Fir seedling nursery, in the soil compaction, poor water permeability, long sunshine, lack of water, the dry season often result in poor growth or a large number of deaths. Shade shade shade, such as investment, large and more workers. Guided by the great instructions of Chairman Mao’s “greening the motherland,” since 1974, we have used shady seeding and nursery plants on the lateral sides of the seedbed to achieve good results. The average annual height of 29.04 cm seedlings, rhizome 0.57 cm, 70,000 mu of seedlings. The method is: In order to enhance the shade effect, the seedbed made north-south. In April, middle and late, on the west and south sides of the seedbed (bed height 1/3
