摘要:
为了展示节点式渗灌管的优良性能和较高的水分生产力，对其做了出水性能检验和不同灌溉方法水分生产力的比较试验，结果表明：节点式渗灌管的灌水均匀度达到90%以上，比普通渗灌管灌水均匀度提高了15%，其节水原理是将土壤通体湿润转化为作物根区灌溉；铺设防渗层有效地阻止了灌溉水的下渗，计划湿润层的变浅和单次灌水量的减少是节点式渗灌能够大量节水的根本所在，节点式渗灌的水分生产力最高，达到70.37 kg/m3，其次是普通渗灌54.55 kg/m3，再次为膜下滴灌53.96 kg/m3，最低为沟灌，仅为42.00 kg/m3。
Abstract:
In order to lay out the excellent capability of the sectional subirrigation and its higher water productivity, the subirrigation quality was checked out. The water productivity by 4 irrigation ways were compared. The study results showed that the soil moisture uniformity exceeded 90% and get higher 15% than ordinary subirrigation. The principles of saving water is translating whole profile wetness into root irrigation. The water seep can be effectively held back by paving impervious barrier. The irrigation water can be saved by shallow plan humid layer and little quantity watering once in a while. Comparing the water productivity with 4 kind of irrigation ways, the best way is sectional subirrigation (70.37 kg/m3), the second is ordinary subirrigation (54.55 kg/m3), the third is dripping irrigation under film (53.96 kg/m3) and the worst one is furrow irrigation (42.00 kg/m3).
