【Abstract】 It was reviewed that the technology of nurserystock survival rate on Loess Plateau in the paper.Survival rate of artificial afforestation was able to increased by protecting water from drought condition include soil water deficit,atmosphere low humidity and strong wind.Soil water content was increased and shoot loss water decreased by soil preparation and suitable afforestation technology,which will be the basis of the increase of afforestation survival rate on Loess Plateau.更多还原
