为加速恢复黄土高原植被和建设牧业基地,丰富黄土丘陵半干旱地区优良牧草种类,我们于1980～1981年先后从盐池草原实验站、山西右玉水保试验站以及甘肃农业大学草原系牧草试验站等单位引入红豆草种子,分别在荒山、退耕地及场圃进行试种。利用雨季在荒山撒播的红豆草,第二年可开花结籽,在退耕地进行春播,当年就能开花结实,生长表现良好。现将三年来的试验研
In order to speed up the restoration of the vegetation on the Loess Plateau and the construction of animal husbandry bases and to enrich the excellent forage species in the loess hilly semi-arid areas, from 1980 to 1981, successively from Yanchi Grassland Experimental Station, Shanxi Youyu Water Conservation Experimental Station and Gansu Agricultural University Grassland Forage Experimental Station The introduction of red bean seeds and other units, respectively, in the barren hills, returning farmland and field nursery for planting. The use of savannah sowing in the barren hills during the rainy season can flowering and seedling the following year and can be sowed in the spring before sowing land for cultivation. Now three years of experimental research
