厂家直销 贴片式滴灌带#节水灌溉材料%喷灌&滴管 品质保证


贴片式滴灌带特点:
1、内镶扁平滴头滴灌带是把扁平形状的滴头镶在管带内壁上的一体化滴灌带，广泛应用于温室大棚，大田经济作物的灌溉。
2、滴头与管带一体化，安装使用方便，成本低，投资少。
3、滴头有自过滤窗，抗堵塞性能好。   
4、采用迷宫式流道，具有一定的压力补偿作用。
5、滴头间距可根据用户要求而定。
6、工作压力：0.02－0.25mpa
7、流量：2-3 l/h
适用条件: 
  （1）用于温室、大棚作物的种植，减少病虫害，节省化肥，提高经济效益。     
（2）用于果园灌溉，可有效提高产量，改善果实品质，有效控制杂草生长。  
  （3）适用于棉花、中草药、西瓜、大田蔬菜等多种大田作物，提高机械化种植力度。    
适用作物： 
  甘蔗，棉花，辣椒，土豆，地面坚果，洋葱，蔬菜，香蕉，草莓，花卉等作物灌溉,适合地表和地下灌溉
注：1盘起邮 壁厚 0.2每盘2000米
                       0.3每盘1500米 
                       0.4每盘1000米
滴灌是利用塑料管道将水通过直径约10mm毛管上的孔口或滴头送到作物根部进行局部灌溉。它是目前干旱缺水地区最有效的一种节水灌溉方式，其水的利用率可达95%。滴灌较喷灌具有更高的节水增产效果，同时可以结合施肥，提高肥效一倍以上。可适用于果树、蔬菜、经济作物以及温室大棚灌溉，在干旱缺水的地方也可用于大田作物灌溉。其不足之处是滴头易结垢和堵塞，因此应对水源进行严格的过滤处理。目前，国产设备已基本过关，有条件的地区应积极发展滴灌。
接管道的固定程度， 滴灌可分固定式、半固定式和移动式三种类型。固定式滴灌，其各级管道和滴头的位置在灌溉季节是固定的。其优点是操作简便、省工、省时， 灌水效果好。国产设备亩投资约为700元（果树）-1400元（大棚蔬菜）。半固定式滴灌， 其干、支管固定， 毛管由人工移动。亩投资为500元-700元。移动式滴灌，其干、支、毛管均由人工移动，设备简单，较半固定式滴灌节省投资，但用工较多。亩投资为2元一500元。
结合中国劳动力多、资金缺乏的具体情况而研究开发的半固定式、移动式滴灌系统，大大降低了工程造价，为滴灌在大田作物和经济欠发达地区推广应用创造了条件。
水窖滴灌， 是通过雨水集流或引用其它地表径流到水窖（或其它微型蓄水工程）内， 再配上滴灌以解决干旱缺水地区的农田灌溉问题。它具有结构简单、造价低、家家户户都能采用的特点。对于旱贫困山区实现每人有半亩到一亩旱涝保收农田，解决温饱问题和发展庭院经济有重要作用，应在干旱和缺水山区大力推广。
地下滴灌，是把滴灌管埋入地下作物根系活动层内，灌溉水通过微孔渗入土壤供作物吸收。有的地方在塑料管上隔一定距离钻一个小孔，埋入地下植物根部附近进行灌溉，群众俗称“渗灌”。
地下滴灌具有蒸发损失少、省水、省电、省肥、省工和增产效益显著等优点，果树、棉花、粮食作物等均可采用。其缺点是2，当管道间距较大时灌水不够均匀，在土壤渗透性很大或地面坡度较陡的地方不宜使用。亩投资为400元-1000元。其效益为：节水50%-60%；省电40%-50%；增产30%左右。
