内镶式扁平滴头地埋式滴灌管

2014年12月30日

  1、内镶式扁平滴头地埋式滴灌管 



  2、使用内镶式扁平滴头地埋式滴灌管做的大田棉花滴灌 

  3、特点:具有舌型滴孔,滴头过滤孔的数量、目数均比常规滴头多,可减少土壤中微小颗粒、细小毛状物进入滴头,提高滴头内部的堵塞性能;可在土层表面以下30~40cm埋地铺设,减少滴灌管光解和老化,一次性铺设可连续使用8年以上,并可实现对作物根系的直接给水、给肥、施药,使得水肥利用率较其他灌溉方式提高30~70%,扩大作物根系在土壤中的分布,增产效果显著,尤其在番茄种植的应用,可使亩产量平均达到13~15吨,可当年收回投资成本,大大减少劳动力和农业灌溉设施的投入,代表未来农业节水发展趋势。

  4、性能:

  1)在田间易于布置和深埋(Is easy in the field to arrange and to bury deeply); 

  2)滴头具有紊流消能作用,抗生物堵塞,滴水均匀(Drop has the affect to turbulent flow to disappear, the resistance stops up, the water drop is even);

  3)一次铺设多年使用(Time lays down,many years use);

  4)适用于水源和劳动力缺乏地区的大田作物,果园、葡萄园、树木绿化等(Is suitable in the water source and the labor shortage area big field crops, the orchard, the vineyard, the trees afforestation and so on);

English:

  has the tongue drop hole, drop filters the hole the quantity and an item number compared to conventional drip irrigation tube drop head increasing, reduces in the soil the molecule, tiny is hairy enters the drop head, enhances a drop interior to stop up the performance; Each kind of specification wall thickness 0.3~0.6mm, may 30~40cm lay down below the soil layer surface, after causes the drip irrigation tube to bury reduces the photolysis and the aging, disposable lays down may above the long-term usage 8 years, and may realize fat to the crops root system for the water, for, executes the medicine directly, causes the sludge fertilizer use factor to compare other irrigation ways to enhance 30~70%, the expanded root system in the soil distribution, the production increase effect is remarkable, in the tomato planter application, may enable the yield per mu especially to amount to the 13~15 ton equally, but the same year recouped the outlay of capital the cost, reduced the labor force and the agriculture greatly irrigates the facility the investment, will save water the development tendency on behalf of the future agriculture.。
