摘要
为了推广应用毛细节水灌溉技术,通过室内试验分析相关技术参数,并依托广西崇左市陇铎片高效节水灌溉工程,建立试验示范区,开展糖料蔗毛细节水灌溉技术试验研究,试验结果表明:糖料蔗在毛细节水灌溉条件下,生育期各生长指标均优于滴灌和无灌溉,其中:株高比滴灌增加1.2 cm,比无灌溉增加30 cm;株茎比滴灌增加0.06cm,比无灌溉增加0.23 cm;每亩有效茎比滴灌增加17株,比无灌溉增加630株;每亩理论产量比滴灌增加0.3 t,比无灌溉增加2.5 t。另外,毛细节水灌溉比滴灌节水5%左右。由此可见,毛细节水灌溉是一种防堵性能好、灌溉均匀度高、具有节水增产的灌溉技术,适合在山丘区糖料蔗节水灌溉。
For spread and application of capillary water-saving irrigation technology,indoor tests were conductedfor analysis of relevant technical parameters; a demonstration zone was set up within the Longze irrigation zone inChongzuo City of Guangxi for test and research of sugarcane capillary water-saving irrigation technology. The re-sults of test show that compared with drip irrigation and non-irrigation,capillary water-saving irrigation of sugar-cane renders better growth indexes such as plant height increasing by 1.2cm and 30 cm,stem diameter increasingby 0.06 cm and 0.23 cm,effective stems per mu（15mu=1hectare） increasing by 17 and 630,theoretical yield permu increasing by 0.3t and 2.5t. Furthermore,water consumption of capillary irrigation decreases by 5% comparedwith drip irrigation. Therefore,capillary water-saving irrigation has superior anti-blocking performance and high irri-gation uniformity,permits less water consumption and renders higher yield,suits to sugarcane irrigation in hilly areas.
