摘要
为了明确膜下滴灌甜菜的需水规律,指导生产科学灌溉,开展灌水量对滴灌甜菜生长发育及产质量的影响研究。结果表明灌水量对甜菜的叶片数影响不大但对甜菜的叶丛高度有明显影响,随着灌水量的增加叶丛高度也增高,在灌水量为360m3/667m2时甜菜叶丛最高。甜菜块根膨大和产质量受灌水量影响显著,在灌水量为120m3/667m2时甜菜的块根直径、根体长度、产量、含糖率及产糖量都处于较低水平,随着灌水量的增加,甜菜的块根大小、产量和含糖率都呈现出上升趋势,但当灌水量大于360m3/667m2时甜菜的产量略有减少,含糖率急剧下降。因此,在玛纳斯产区膜下滴灌甜菜灌水量控制在360m3/667m2左右较为合理。
The experiment of drip irrigation was carried out to study influence of drip irrigation amount on growth and development, yield and quality of sugarbeet. The results showed little effect of irrigation amount on beet leaf number, but obvious influence on beet foliage height. Foliage height was increased with increasing irrigation quantity. Beet leaves was the highest when the irrigation amount was up 5400m^3/ha. The enlargement, yield and quality of beet root were significantly affected by irrigation amount. The diameter, length, yield, sugar content and sugar yield of beet root were low when the irrigation amount was up 1800m^3/ha. The size, yield and sugar content of sugarbeet root were shown a rising trend with increasing irrigation amount. But beet yield was decreased slightly and sugar content was sharply declined when the irrigation amount was more than 5400m^3/ha. Therefore, 5400m^3/ha as the reasonable irrigation amount was suggested in Manasi areas of Xinjiang.
