广西糖料蔗滴灌方式下不同灌溉定额效益成果分析

摘要

Experiments were conducted by two irrigation modes of buried drip irrigation and surface drip irrigation. Under the condition of natural rainfall being made full use,three kinds of irrigation quotas of 150m3/mu,250 m3/mu and 350 m3/mu (15mu=1hectare) were tested to study the influence of different quotas on yield and quality of sugar⁃cane. The results of tests demonstrate that buried drip irrigation at quota of 250 m3/mu is able to satisfy water re⁃quirements of sugarcane and increase yield to certain extent.%本试验通过采用地埋式滴灌、地面滴灌两种灌溉方式，在充分利用天然降雨的情况下，设置不同灌溉定额150 m3/亩、250 m3/亩、350 m3/亩，研究不同灌溉定额对糖料蔗产量、品质的影响。结果表明：地埋式滴灌在150 m3/亩的灌溉条件下能较好的满足甘蔗对水分的需求，产量有所提高。
