甜菜块根的含糖率是甜菜最重要农艺性状和工艺品质。一百多年来人们为了从块根中获得更多的糖,想方设法提高含糖率,取得了很大成就。但是由于自然条件的限制和栽培措施的影响,甜菜的含糖率总是达不到理想的程度。河西走廊气候凉爽,日照充足,昼夜温差大,雨量稀少而靠人工灌溉。气候条件对甜菜生长有利,同时可以通过水、肥人为地控制其生长,所以含糖率是比较高的,是我国的甜菜高糖区之一。虽然如此,但也有一些不利因素妨碍甜菜的生长,加之栽培措施跟不上,低糖情况还是经常出现。
Sugar beet root tuber sugar content is the most important agronomic traits and process quality. For more than 100 years, people have made great achievements in finding ways to increase their sugar levels in order to get more sugar from roots. However, due to the restriction of natural conditions and cultivation measures, the sugar content of beet always fails to reach the desired level. Hexi Corridor cool climate, adequate sunshine, large temperature difference between day and night, scarce rainfall by artificial irrigation. Climate conditions on the growth of sugar beet beneficial, at the same time through water, fertilizer artificially control their growth, so the sugar content is relatively high, is one of the sugar beet high sugar areas. Nevertheless, there are some unfavorable factors that hinder the growth of sugar beet, combined with the cultivation measures can not keep up, the low sugar situation is often seen.
