摘要
根据草地生态学和生物学原理，利用系统工程研究方法，在水土流失区、红壤山地和丘陵地筛选利用１８种优质高产牧草，园果雀稗、卡松古鲁狗尾草、拟高粱、宽叶雀稗、马唐、多花木兰等建植人工草地和草果（林）结合植被达１４００ｈｍ２。保持了水土，改善了土壤肥力和果树（林木）的生长环境，提高了果树（林木）的生长速度，增加了果树的产量（＋１０％）和果实品质（糖度提高３°），获得了高产优质的饲料，每公顷草料可生产４５０个畜产品单位的牧业产品。通过草粉代替鼓皮等精料（代替率为５％～２６．２％），可降低饲养成本１３．５１％。利用牧草作菌基栽培食用菌，节省了大量林木，投入产出比提高到１：１０以上，从而大幅度地提高了牧草的经济效益、社会效益和生态效益。
Based on principle of grassland ecology and using engineering research methods,1400hm2 of sown pas-tures on their own or with fruit or other trees has been established between 1981 and 1991.Eighteen foragespecies have been utillzed,including Paspalum orbiculare,Setaria sphacelata cv. Kazungula,ect.As a result ofestablishing these improved pastures on hillyland reclaimed for growing fruit trees,water erosion has beendecreased and the low-feeding value native grasses have been replaced.Reduced runoff has improvedwater avallability to fruit trees and improved Soil fertility,improved the growth of trees,thus yield oforanges and sugar degree are increased by 10%and 3°espectively.At the same time,lot of fine forage isgained and 4 5 0 livestock unit can be produced on 1 hm2 grassland.Through replacing bran with grasspowder(replacing rate is 5%～26.2%),feeding cost can be cutten by 13.54%. Lots of woed can besaved by using grass to produce eolible fungus,at the same time,the ratio of input to output of grass is ashigh as 1:10.Therefore,grass economic,social,ecologieal benefit are greatly developed.
