DGT增效剂对滴灌甜菜产质量效应研究

Effects of DGT Synergist on Sugarbeet Yield and Quality under Drip Irrigation Cultivation Model

在甜菜营养生长阶段通过生物或营养调控调节甜菜的生长发育是甜菜生产中实现原料甜菜优质高产高效的一项重要农艺措施.为在滴灌条件下寻求稳产提糖的成熟技术产品,稳定原料产区面积、降低制糖企业吨糖成本,提高企业可持续发展能力,在新疆喀什和甘肃张掖地区通过两年六个点大区对比法进行了DGT增效剂的示范试验.结果表明,DGT增效剂适应性广,效果稳定,在两年两个地区六个示范点上的表现一致,在甜菜营养生长期内通过水肥一体化方式施用可极显著地增加甜菜块根产量(P<0.01)、含糖(P<0.01)和单位面积上的产糖量(P<0.01).

It is an important agronomic measure to adjust the growth and development of sugar beet through bio-logical or nutritional regulation in the vegetative growth stage of sugar beet to achieve high quality,high yield and high efficiency in sugar beet production.In order to seek mature technology products with stable yield and sugar extraction under drip irrigation,stabilize the producing area of raw beet,reduce the sugar cost per ton of sugar production enterprises,and improve the sustainable development ability of enterprises,the demonstration test of DGT synergist was carried out in Kashgar of Xinjiang Province and Zhangye of Gansu Province by six sites large area comparison method in two years.The results showed that DGT synergist had wide adaptability and stable effect,and showed consistent performance in six demonstration sites in two regions during two years.During the vegetative growth period of beet,the integrated application of water and DGT synergist could significantly in-crease the root yield(P<0.01),root sugar content(P<0.01)and sugar yield per unit area(P<0.01).
