Astragalus adsurgenspall is a perennial herb of Astragalus and is an excellent grass species for sand fixation, soil conservation, forage and green manure. Suitable for soil and water loss areas, sandstorm area planting, the former in the introduction of cultivation of the main problems is the low seed yield, affecting the expansion of planting. In order to improve the planting technology and provide the basis for increasing the yield of seeds, we observed the growth and development of Astragalus Mongol from 1973 to 1977 in our country. The data are summarized as follows. First, the methods and results (a) the relationship between vegetative growth and sowing date. In 1974 Ansai County Riverside Commune Chafang brigade cited Jiangsu
