为进一步发展柞蚕生产,必须加强蚕场建设,开辟新的饲料来源.一方面把现有蚕场里的空隙地补植起来:另方面要在荒山大面积营造新蚕场.这里介绍几种简易措施.1.环山修等高梯田种柞树把荒山坡修成等高梯田,播种柞树种子,比按原来的坡形直接刨坑播种橡实出苗齐、生长快.具体作法是:根据山势,每隔1.5米宽,修一条环山等高梯田带,在水平面上播种橡实.作业顺序:先在计划修建等高梯田带的下线开一条深30～40厘米、宽40～50厘米的沟.把草皮和熟土填在沟内,并将上侧的土和砂石等扒到下侧,使下侧稍高点,以便起到兜水的作用.
In order to further develop the tussah production, we must strengthen the construction of the silkworm farms and open up new sources of feed, on the one hand, replant the gaps in the existing silkworms market: on the other hand, create new silkworm farms on a large area of barren hills. Measures 1. Huan Shan Xiu and other high terraces planted oak trees to the wasteland slopes into high terraces, oak seed sown than the original slope-shaped direct planing seedlings planted oak sprout Qi, grow faster. The specific approach is: According to the mountain, Every 1.5 meters wide, repair a high terraced mountain ring, seeding acacia in the horizontal plane.Operation order: first planned to build contour terraces in the open a depth of 30 to 40 cm, width 40 to 50 cm Ditch the turf and cooked soil fill in the ditch, and the top of the soil and gravel to the lower side, so that the lower side slightly higher in order to play the role of pocket.
