1、內(nèi)鑲式扁平滴頭滴灌管(帶)
2、特點:是在圓柱滴頭流管基礎上發(fā)展的新一代節(jié)水灌溉產(chǎn)品,滴頭一次性注塑成型,具有新型的寬長流道,自帶過濾窗,寬大的過濾面積和流道斷面尺寸,抗堵塞性能強,水流呈全紊流,出水均勻度良好,滴頭直接焊接在管子內(nèi)壁,壓力損失小,灌水精度高等特點;工作壓力范圍40~120kpa,不同規(guī)格適合不同大田作物的灌溉用,價格低,安裝運輸、使用方便,是經(jīng)濟型節(jié)水產(chǎn)品,適應精準化農(nóng)業(yè)的發(fā)展要求。
3、性能:
1)重量輕,在田間易于布置和收取(Weight light, is easy in the field to arrange and to gather);
2)滴頭間距150mm~2000mm,可根據(jù)用戶需求調(diào)整(Drop spacing 150mm~2000mm, may act according to the user demand adjustment;)
3)抗機械強度好,便于機械化作業(yè)鋪設(The anti- mechanical strength is good, is advantageous for the mechanized work to lay down);
4)適用于大田作物,大棚蔬菜及花卉、果樹種植(Is suitable in the big field crops, the vegetables and the flowers and plants)
