星星草、朝鲜碱茅在内蒙古河套灌区盐碱地栽培技术
CULTIVATION TECHNOLOGY OF ALKALIGRASSES IN SALINO-ALKALI SOILS, HETAO IRRIGATIONAL AREA
【摘要】 在内蒙古河套灌区以硫酸盐、氯化物为主的中度和重度盐碱地秋季深翻灌溉,第二年春季耕翻撒播或条播星星草、朝鲜碱茅,覆土1厘米,灌溉,间隔七天后再灌二次水,可保证出苗率达90%。以后在不同生育期各灌水一次,施些化肥,亩产鲜草达1500公斤左右。在巴盟河套灌区中度和重度盐碱地上可大面积种植。
【Abstract】 In hetao plain,we seeded two cultivars of salino-alkali hardiness alkaligrasses (Puccinellia tenuiflora / P. chinampoensis) in the heavy/less heavy-salinoalkali soils which include sulphates and chlorides for years. The technology of cultivation we adopted consisting of deep ploughing and enough irrigation in autumn. In the next spring,we plowed and seeded these two grasses by broadcast seeding or sowing in drills,and covered with soil by centimetre and then irrigated. Seven days later we irrigated the field twice again. From then on,irrigations in different plant growth periods were carried out,and fertilizers were dressed, too. The seed energing rates were proved above 90% and the fresh matter yields recorded 1500 kg/mu. We are eonfident that adopt this method of eultivation salino-alkali tolerant forage grasses could be extended in hetao irrigations areas.
