江苏省低山丘陵面积占全省总面积的15%,约2000余万亩。除现种植有林、竹、果、茶、桑之外,还有较大面积未开发利用,仍处于荒山草坡状态,估计有300—400万亩。植被中的野生草种主要有黄背茅、荩草、白茅、夏枯草、鸡眼革以及野蒿等。草质差,产量低,平均亩产鲜草仅450—550公斤。本试验的目的是通过种植牧草,筛选出适宜低山丘陵地区种植的优良牧草品种,建立人工草场,提高草质和产量,为发展草食
Hilly area in Jiangsu Province, accounting for 15% of the total area of the province, about more than 2000 acres. In addition to the current planting of forest, bamboo, fruit, tea, mulberry, there is a large area of undeveloped and still in use, still in the state of barren hills and slopes, an estimated 300-400 acres. The wild grasses in the vegetation are mainly yellow dorsal grass, ragweed, white grass, Prunella, coriander and Artemisia. Poor grass quality, low yield, the average yield of fresh grass only 450-550 kg. The purpose of this experiment is to screen the suitable forage varieties suitable for planting in the hilly area by planting forage grass, establish artificial grassland, improve the grass quality and yield,
