适合沙地种植的牧草有沙打旺、红豆草、草木樨、小冠花等。 1.沙打旺 是豆科黄芪属多年生草本植物,适应性很强,产草量高,是饲用、绿肥、防风固沙、水土保持的优良牧草。 沙打旺喜温暖气候,在20℃~25℃的温度下生长最快,适宜在年平均气温8℃~15℃的地区生长。沙打旺种子很小,千粒重1.7~2.2克。在播种前结合翻耕施用一定量的农家肥和磷肥,以提高产草量和种子产量。沙打旺在河南以秋播为主,可条播、撒播、点播,大面积的沙滩、荒山可采取飞机播种。由于种子小,播种深度以1.0~1.5厘米为宜,播种量每667平方米0.25~0.50公斤,种子田0.10~0.15公
Suitable for the cultivation of sand pasture Astragalus, safflower grass, vegetation, such as small crown. 1. Astragalus is Astragalus Leguminosae perennial herb, strong adaptability, high yield, is forage, green manure, wind and sand, soil and water conservation excellent forage. Sands Wang hi warm climate, the fastest growth in the temperature of 20 ℃ ~ 25 ℃, suitable for the annual average temperature of 8 ℃ ~ 15 ℃ in the area of growth. Sow Wong seed is small, grain weight 1.7 ~ 2.2 grams. Before sowing combined with tillage application of a certain amount of manure and phosphate fertilizer to increase the amount of grass production and seed yield. Sandy Wang in autumn in Henan based, can be broadcast, broadcast broadcast, on-demand, a large area of the beach, barren mountains can be sown by plane. Due to the small seeds, sowing depth of 1.0 to 1.5 cm is appropriate, sowing rate of 0.25 ~ 0.50 kg per 667 square meters, seed fields 0.10 ~ 0.15
