In the middle ages of 1970’s

Northwestern institute of soil and water conservation carried out scientific inves-tigation and started long term field experiement and demonstration in arid hilly area of the south Ningxia under thesupport of Chinese goverment. Based on deep and systematic studies

from the policy of production construction topractical technology of efficient agriculture

followsnig comprehensive development strategies and technologicalmeasures have been proposed:″planting grass and shrub at first″

″fundmental way out lyiny in fertilizer

″to opti-maze agricultural structure″

″systems increasing crop yield of arid areas

″techniques of orchard establishrnentwhich produce. abundant yeild and preduce fruitearlier with water saving in the production.″The factors of waterscience and technology and material input shortage have been three great inhabitors to develope efficient agriculturein this area

especially the lack of qualified scientixts and technicians andfunds. Therefore

to take developingstrategies such as considering overall situatio

making overall plans and considering all factors

solving key prob-lems

promoting gradually and so on

to pursue techniques increasing yield efficiently and practically to developemain industrial and to cultivate market economy will be significant to develope economy rapidly.
