滴灌属全管道输水和局部微量灌溉,使水分的渗漏和损失降低到最低限度。同时,又由于能做到适时地供应作物根区所需水分,不存在外围水的损失问题,又使水的利用效率大大提高。灌溉可方便地结合施肥,即把化肥溶解后灌注入灌溉系统,由于化肥同灌溉水结合在一起,肥料养分直接均匀地施到作物根系层,真正实现了水肥同步,大大提高了肥料的有效利用率,同时又因是小范围局部控制,微量灌溉,水肥渗漏较少,故可节省化肥施用量。 Drip irrigation is a kind of whole pipeline water conveyance and local micro-irrigation, which can minimize the leakage and loss of water. At the same time, due to the timely supply of water needed in crop root zone, there is no loss of peripheral water, and the water use efficiency is greatly improved. Irrigation can be combined with fertilization conveniently, that is, the chemical fertilizer is dissolved and poured into the irrigation system. Because the chemical fertilizer is combined with irrigation water, the fertilizer nutrients are applied directly and evenly to the root layer of crops, which realizes the synchronization of water and fertilizer and greatly improves the effective utilization rate of fertilizer. At the same time, because of small-scale local control and micro-irrigation, Water and fertilizer leakage is less, so the amount of chemical fertilizer application can be saved. 运用灌溉施肥技术,为作物及时补充价格昂贵的微量元素提供了方便,并可避免浪费。滴灌系统仅通过阀门人工或自动控制,又结合了施肥,故又可明显节省劳力投入,降低了生产成本,提高了资源利用率,保证了全覆盖灌溉。 The application of irrigation and fertilization technology provides convenience for timely replenishment of expensive trace elements for crops and avoids waste. Drip irrigation system can save labor input, reduce production cost, improve resource utilization and ensure full coverage irrigation by manual or automatic control of valve and combining fertilization. |
