建设人工草场,是科学治理“三化”(沙化、碱化、退化)草原的一项有效的生物措施。在种植牧草时,应按地块定品种,查墒情定播期,按品种定播种量,按地形定播种方法。一、抓住有利时机播种。根据松嫩草场春旱、多风的自然环境特点,不应过早整地,应接近播期整地为宜,以利保墒和防止风剥,播种应在6月15日后为妥。二、播种时期掌握风向。当地多西北风、故应采取西北——东南方向平播或南北方向播种为宜。 The construction of artificial grassland is an effective biological measure to scientifically manage the “three” (desertification, alkalization and degeneration) grasslands. In the cultivation of forage, should be determined by the land of varieties, soil moisture conditions seeding date, according to the species sowing, according to the terrain sowing methods. First, seize the opportunity to seeding. According to the characteristics of spring and windy natural environment in Songnen pasture, it should not be prematurely ground, and should be close to sowing site preparation to facilitate soil moisture and prevent wind stripping. Seeding should be done after June 15th. Second, grasp the wind direction during planting. Local multi-northwest wind, it should be taken northwest - southeast or flat sowing sowing is appropriate.
