為達成農地水土保持植生的任務，必需在有效生育期之短短半年內完成全面覆蓋，使山坡地資源保育利用，達到零缺點，零災害。將更積極以噴灌，微噴等方式兼顧安全排水系統，做好密集之植生管理工作，據觀察有灌溉之植生，第一年新植之增殖率可達600~700倍，而暗渠排水可避免地滑之災，又果園山邊溝處理配合植生覆蓋，每公頃年土壤沖刷流失量近於零，又有植生之涇流量亦有減低之趨勢。綜觀上述此仍將過去看天之機會灌溉法，演進為更科技的措施，以求達到事半功倍之效，呈現富麗農村之新面貌。

For enhancing the conservation effect of vegetation on farmlands, it is necessary to cover the grass completely within six months after grass-planting, and to conduct proper irrigation and drainage practices for management of the vegetation established. Here first, we are pleased to introduce the irrigation methods for farmlands and for environmental greening and beautification. Second, we will discuss methods of drainage. For irrigation of farmlands: l.The rainy season is the main water supply for newlyplanted vegetation. 2.Grass planted on sideslopes of the road are usually irrigated manually with a hose. 3.1nstall several rows of sprinklers combined with the computer system to irrigate. For environmental greening and beautification: l.pop up type sprinkler, 2.spraying head against the perimeter, 3.under tree type micro spraying head. Secondly for the drainage of on ground: l.hillside ditch, 2.prefabricated ditch or flume, 3.parabolic shaped water way, 4L-shaped ditch. For underground drainpipe. Many observations on vegetation management have given significant results. The reproduction rate of the newly planted grasses in the first year increased about six hundred to nine hundred times under irrigation. The treatment of the orchard hillside ditching in combination with the practice of grass-covering reduced the annual soil loss to approximately zero. The runoff rate on the grass- covered land decreased greatly. With improved technology, several irrigation and drainage practices have showed their merits in maintaining and conserving vegetation on farmlands .
