１９９３～１９９５年，通过在郑州地区试种朝鲜碱茅和星星草，对其在中原地区的适应性及其对土壤的改良效果进行了试验观察。结果表明，二种碱茅能很好适应黄淮海平原的气候及土壤条件，生产性能及生物学性状良好，耐盐能力强，能有效改善土壤肥力。混播此二种牧草，既可为畜牧业提供优质高产饲料，又能改良大面积的盐碱地。 In 1993-1995, we experimented on the adaptability of the soil and its adaptability to the soil in the Central Plains through the experiment of planting Alhummis sagittana and Prunella vulgaris in Zhengzhou area. The results showed that both of them could adapt well to the climate and soil conditions in the Huang-Huai-Hai Plain, with good production performance and biological characters, strong salt tolerance ability and effective improvement of soil fertility. Mixed with these two pastures, both for livestock husbandry to provide high-quality high-yield feed, but also to improve large-scale saline land.
