Description
The irrational land utilization has resulted in destruction of original vegetation and serious soil erosion on the Loess Plateau in China. At present, 1600 million ton of sediment is discharged into the Yell ow River per year. In order to explore effective avenues to speed reestablishing vegetation for controlling soil erosion, we made an experiment in seeding forage and shrubs by airplane for four years, from 1976 to 1979, in semiarid region on the Loess Plateau. We selected suitable plant species for aerial seeding on semiarid region, determined fit aerial seeding time and seeding rate through manual broadcast and air-seeding. We have met with success on aerial seeding Astragalus adsurgens, Caragana microphylla and Hippophae rhamnoides. The air-seeding A. adsurgens and other forage has been popularizing in China since 1979. Growing luxuriantly from second to eighth year, A. adsurgens consumed a lot of water and made subsoil moisture between 0.6 and 5 or 8 metre reduced to 4-6 % . Some specialists paid closed attention to this problem, being afraid other plants can not grow after A. adsurgens declining. So we made researches on dynamics of soil moisture and vegetation structure of aerial sowed A. adsurgens pasture from 1980 to 1986, to evaluate the feasibility of aerial seeding A. adsurgens in large scale.
