使用劣质滴灌带原来有这么多的坏处啊!
一费工：拉伸强度不够，播种铺设过程中滴灌带断裂，影响播种速度，增加铺设安装费用。
It takes a lot of work: the tensile strength is not enough, the drip irrigation belt breaks in the process of planting and laying, which affects the planting speed and increases the installation cost.
两不匀：灌水不均匀，施肥不均匀;劣质滴灌带在应用过程中，产生老化破裂或爆管，有的地方滴灌变淹灌，有的地方迷宫吸死或堵塞不出水，靠近支管的地方过量灌溉，两个支管中间的地方灌水不够，田间庄稼一片高、一片低，造成水肥浪费，平均亩用水量增加20-30立方米，长势不匀又会对对机械打顶、机械采收等造成影响，成本增加。
Two uneven: uneven irrigation, uneven fertilization; poor quality drip irrigation belt in the application process, resulting in aging rupture or pipe burst, some places drip irrigation into flooding, some places maze suction or blockage water, near the branch of the place of excessive irrigation, two branches in the middle of the place of insufficient irrigation, field crops a high, a low, resulting in waste of water and fertilizer, the average water consumption per mu increased by 20- 30 cubic meters, uneven growth will also have an impact on mechanical roofing, mechanical harvesting and other costs.
三降低：产量低，以棉花为例，因水肥不匀一般每亩减产在20kg籽棉以上;运行压力低，劣质滴灌带往往承压能力差，容易爆管漏水，流道结构不优，滴头流量大，采用原有轮灌方案将造成低压运行，而低压运行直接后果就是整个系统的灌水均匀性大幅降低，不能充分发挥滴灌灌水均匀的优点;水泵运行效率低，低压运行还会造成水泵不在高效区运行，同样水量的电费会增加，同时，容易烧毁电机，增加维修费用。
Three decreases: low yield, take cotton as an example, because of uneven water and fertilizer, the yield of seed cotton is generally reduced by more than 20 kg per mu; low operating pressure, poor quality drip irrigation belt often has poor pressure-bearing capacity, easy to burst pipe leakage, poor www.china-pipe.com.cnwww.chenyei2009.cnzhixuedai.71ix.compesuomo.37ix.com.cnrunner structure, www.lhsilicone.cnwww.gzcucaoduyi.cnlarge dripper flow rate, the original rotation irrigation scheme will cause low-pressure operation, and the direct consequence of low-pressure operation is that the irrigation uniformity of the whole system will be greatly reduced and can not be filled. Give full play to the advantages of uniform drip irrigation; low efficiency of pump operation, low-pressure operation will also cause the pump not to operate in the high-efficiency area, the same amount of water will increase electricity costs, at the same time, it is easy to burn down the motor, increase maintenance costs.
