This voluntary code addresses issues such as reduced pesticide use, water and energy conservation, waste reduction and recycling, controlling of erosion, the use of “ good bugs ” in the vineyard to kill the “ bad bugs ”, creating and maintaining a habitat for raptors and other wildlife around the vineyards, planting cover crops such as mustard grass and clover to replenish the soil with nutrients, improved farm worker housing, and other measures for making high quality wines in a responsible manner
這個自主的規定公布了如減少殺蟲劑的使用，水和能量守恆，損耗的減少和再生，腐蝕的控制，利用葡萄園里有益蟲殺死有害蟲，創造和保護在葡萄園附近的鳥類和其他野生動物的生存環境，種植覆蓋地表的植被如芥菜和三葉草補充土壤的養份，改善農場工人的住房，和其他能提高葡萄酒質量的有效的方法。 -
Description : alfa - alfa integrated in the no - till system. as the crop remains in place during 3 - 4 years, various cover crops are intercropped o keep enough residue cover. epagri

The most environmentally benign form of agriculture appears to be “ no till ” farming, which involves little or no ploughing and relies on cover crops and carefully applied herbicides to control weeds
最環保的農業生產方式似乎是「免耕」播種，這一生產方式很少或不再耕作，依賴表層植被並謹慎使用除草劑。 -
Description : cover crops for conservation agriculture, diversification and biodiversity : radish ( iapar variety ), very effective for weed control, decompaction and good fodder ; lots of bees in the field

Aiming at the ecological environmental deterioration of bashang, from 2002years to3 ~ 5months of 2003 years. sand - transporting quantity of land cover types were on - the - spot moinitoring in gale seaon, comparing the productivity of the main crops. improving environment and developing economy are compositively considered for applying returning cultivated to woodland and grassland to supply the base of theory and technology. the main results as following : 1 observing the sand transporting quantity of artificial grassland, stubble land and cultivate land. indicates that when wind speed is higher ( 8. 0m / s ), the sand transporting quantity of artificial grassland of 200cm reduces 35. 5 % in average more than that of cultivate land, 34. 5 % sand - transporting quantity than that of stubble land. no distinct difference between stubble land and cultivate land. and when wind speed is lower ( = 5. 0m / s ), the sand - transporting quantity of coverage is no distinct difference according to the analysis of variance
從改善環境和發展經濟兩方面綜合考慮，為實施壩上地區「一退雙還」提供了理論與技術依據。主要研究結果如下： 1對人工草地、作物留茬地及耕翻地的輸沙量觀測表明：勁風（ 8 . 0m s ）下，人工草地比對照耕翻地輸沙量在200cm高度內平均降低了35 . 5 ，比作物留茬地平均降低了34 . 5 ；作物留茬地輸沙量與耕翻地差異不顯著；微風（ 5 . 0m s ）下，不同地表覆被類型對輸沙量的影響差異不顯著。 -
In abroad, the study of integration site used for transgenic detection had just begun. in this study, according to the collection of the global commercialized transgenic crops, select seven exogenous genes which basically cover the total commercialized crops, namely camv35s and fmv promoter, nos terminater, mark gene nptii, and aim genes pat, epsps and cryia ( b ). use endogenous 18srrna gene as collate, design a large pairs of specific primers, screen the optimum primers groups, optimized the test condition and parameters, establishing the qualitative pcr detection system
本研究根據收集的國內外已商品化的轉基因作物品種，選擇了能基本覆蓋商品化轉基因品種的7個外源基因，即： camv35s 、 fmv啟動子、 nos終止子、 npt標記基因和目的基因pat 、 epsps 、 cryia （ b ）作為篩選目標，以植物18srrna基因作為內源參照基因，設計了多對特異性引物，並篩選出最佳組合，優化了檢測條件和參數，建立了pcr定性檢測方法體系。 -
Obviously, these results underline the experience of numerous upland farmers : cultivation without safeguarding a fast and stable vegetative cover of crops inevitably leads to soil loss which means loss of productivity
顯然，這些結果與無數旱地農民的經驗相符合：沒有保證作物快速穩定的植被覆蓋層的耕作無疑會造成土壤損失，進而引起生產力損失。
