In this paper authors expounded the functions of Astragalus adsurgens in making full use of land and water resources,controlling soil and water loss,improving soil and increasing land capability accord- ing to experiment result on product and soil moisture of A.adsurgens grassland in 13 years,from second year after seeding to third year declin- ing.The product of A.adsurgens grassland during third to seventh year was 8 times more than natural grassland,but the water consumption of the former just was 30% more than the latter.After A.adsurgens declining for 1~3 years,the yield of after reap crop or natural grasses and herbs increased by 100%~200%.Authors consider the mechanism is that the ineffective water loss,such as runoff and soil evaporation,isdecrea- sed in A.adsurgens grassland,so much more rain water and storage of deep subsoil layer become into effective water for dry matter production, and A.adsurgens improved soil physical property and fertility so water use efficiency is increased greatly.This study offers science festimony for establishing grassland—animal production—agriculture ecosystem with stable and high productivity on the semiarid loess plateau.

本研究通过对吴旗飞播沙打旺草地(由播种到衰败后,前后13年)产量动态和土壤水分变化的分析,论述了黄土高原半干旱区沙打旺充分利用土地、水分资源,控制水土流失,改良土壤,提高土地生产力的重要作用。沙打旺草地通过改善土壤物理性质和肥力状况,减少径流、土壤蒸发等水分无效损耗,使降水和土壤储水变为有效水,从而提高了水分利用率。在3~7年生沙打旺草地中产草量为荒山草地的8倍,而总耗水量仅为荒山草地的1.3倍。沙打旺衰败后,2~3年内,后茬作物或天然草类产量均较对照提高1~2倍。本研究为建立草—畜—农稳定高效农业系统提供了科学依据。同时就土壤水分平衡问题提出了提高水分利用率,在一个较长时间的周期中实现相对平衡的论点和实行草粮宽带间轮作的战略措施。

Among the common elements existed in earth's crust, fluoride is ranked thirteenth in total amount, and plant is the most sensitive bio-acceptor of atmospheric fluoride. In recent years, the relation between gaseous fluoride and eco-system has been quantitavely studied, through field investigation and artificial exposure experiment. There are a lot of literatures have reported the results of effects of atmospheric fluoride on agriculture ecosystem. These, results were comprehensively reviewed through the effects of fluoride on crops, livestock and mulberry-silkworm in this paper.
