14、泵房設(shè)計(jì)圖、鎮(zhèn)墩示意圖以及滴管出水口的連接詳圖等。本設(shè)計(jì)灌溉方式使作物的灌溉周期進(jìn)一步縮短，增加了農(nóng)田的灌溉次數(shù)，提高灌溉保證率，保證了作物適時(shí)、適量灌溉，從而達(dá)到節(jié)水、省工、省肥和增產(chǎn)增收的效果。本項(xiàng)目實(shí)施后每年增加凈產(chǎn)值24.57萬(wàn)元。考慮0.5的水利效益分?jǐn)傁禂?shù)，年增灌溉效益12.258萬(wàn)元。年可增加效益為13.9658萬(wàn)元。關(guān)鍵詞：枸杞；滴管；節(jié)水；增收。GansuYumenwillowreachesmedlardripirri
