补充资料：碱茅
| 碱茅 禾本科碱茅属中的一个种，学名Puccinellia tenuiflora (Turcz) Scribn & Merr,多年生草本植物，为牧草作物。又名星星草。在中国东北、西北、华北有野生分布。 株型较小，高30-60cm，茎直立或基部略膝曲；叶片长3-7cm，通常内卷，叶面微粗糙，叶背光滑，灰绿色；圆锥花序，开展，小穗含3-4朵小花，颖与外稃质地薄，颖果纺锤形，成熟后紫褐色。种子千粒重0.7g左右。 适应性强，喜湿润和盐渍性土壤，耐碱、抗寒、抗旱，土壤pH为8.8时，仍能生长发育良好。以雨季播种为宜。一般采用机械或人工条播，行距15-30cm，每公顷播种量7.5kg左右，在碱性很强的碱斑草原上，宜灌水后播种，以降低出苗前后地表的盐碱度。干物质中含粗蛋白质16.17%，粗脂肪2.52%，粗纤维30.72%，无氮浸出物44.08%，灰分6.51%。 |
