辽宁省西北部风沙区的科尔沁沙地边缘,分布有大面积的风沙土.本地区风沙干旱,土质瘠薄,耕作粗放,广种薄收,农作物产量低而不稳.试验和生产实践表明,种植牧草绿肥,实行粮草(油)轮作,是改良利用风沙土,用地养地相结合,促进农牧业发展的重要途径.但是由于土壤贫瘠,又常发生风剥沙压、干旱和草荒,因而影响了牧草绿肥,特别是草木樨的发展.根据我们在所内外进行的试验研究结果,在风沙土上种植草木樨,必须抓好以下几
In the northwestern part of Liaoning Province, there is a large area of wind-blown sand on the edge of Horqin Sandy Sandy Area in northwestern Liaoning Province.The wind-blown sand, poor soil quality, extensive cultivation, wide variety of thin harvesting, low and unstable crop yield in this area.Experimental and production practices show that planting green grass, The implementation of forage grass (oil) rotation is an important way to improve the combination of wind-blown soil and land-use and to promote the development of agriculture and animal husbandry.But due to poor soil, wind stripping and sand pressure, drought and grassland shortage often occur, , Especially the development of plants and trees.According to the results of the pilot study conducted both inside and outside of our country, we must pay close attention to the following
