樟子松固沙疏林农林牧循环立体经营技术的研究

STUDY ON TECHNIQUES OF ROTATION MANAGEMENT OF CROPS, FOREST AND PASTURE IN THE DUNE FIXING SPARSE FOREST OF PINUS SYLVESTRIS VAR.MONGOLICA

１９９７年雨季在泰来县江桥镇、街基乡分别营建了半固定沙丘、沙地樟子松固沙疏林，在疏林行间播种培育了沙打旺、锦鸡儿、沙棘、黄芪、黄芩、防风、甘草、大豆、红小豆、绿豆、荞麦等，形成农林牧循环（轮作）立体经营樟子松固沙疏林体系。经对苗木进行生化处理以及采用雨季造林技术，樟子松、沙棘成活率保存率高。中草药、牧草、农作物产量和质量达到当地先进水平。通过调查，植被盖度迅速提高，有效地控制了风蚀。系统运行 ４年来，稳定良好。

Dune-fixing sparse forests of Pinus sylvestri s var.mongolica were afforested on unstable dunes and sandy lands in Tailai County in the spring of 1997,Between rows of the forests were sowed sand-binder, peatree, sea buckthorn, milk vetch, licorice, soybean ,red bean, mung bean and buckweat, etc. Formed a system of dune fixing sparse woods was managed in tegratedly. Survival rates of P. sylvestvis var. mongolica and sea buckthorn were higher by treating seedlings and Planting during rainy season. Production and quality of the Chinese medicines, grasses and crops have come up to advanced level in local area. Cover-degree of vegetation raised and controlled wind erosion. The system has run stably for 4 years.
