3“Our fertilizer is the result of the fermented (发 酵) mixture of livestock waste and crop straws,”said Zhang Jian,deputy general manager（副总经理）of Yunling Organic Agriculture Development Co., Ltd.“After several years of trial planting, it is proved that the development of organic agriculture in sensitive water source areas plays a positive role in soil improvement and ecological restoration.”

4Now,more than 50 tons of vegetables of more than 20 varieties from the field are sent to places across China every day.Although the price is three to five times higher than that of ordinary vegetables,they are popular in the middle and high-end retail markets in East, Central and South China.In Tonghai County, one of the main producing areas,organic vegetables have begun to enter the Southeast Asian market.

5At present,Yunnan produces 32 million tons of vegetables per year.With the promotion of organic farming,the vegetable industry is facing a major transformation.

6“A revolutionary change should be made to the traditional growing mode or cultivation technology. If the zero emission of chemical residues（残留物）is realized, our problems of environmental pollution will be solved,”said He Jiangming, a researcher at the Institute of Horticulture,Yunnan Academy of Agricultural Sciences.
