本文通过对不同棚式和不同透光度的对比试验,结果表明:双畦单透光脊棚优于单畦单透斜棚,日均光强提高130%,单根鲜重、根长、根粗和侧根数都有明显增加,土地利用率提高11.11%;5%、10%、15%、及20%四种透光棚相比,以透光20%表现最好,西洋参生育健壮,光合速率高,参根增重快,比对照参根增产52%。 In this paper, the contrast test of different sheds and different light transmittance shows that: the double 畦 single translucent ridge is better than single 斜 single transversal slope, the daily average light intensity is increased by 130%, single root fresh weight, root length, Compared with the four kinds of light-permeable sheds of 5%, 10%, 15% and 20%, the light-harvesting performance of 20% was the best, and the growth of American ginseng was robust. High photosynthetic rate, root weight gain faster than the control root yield 52%.
