甜菜的产量、产糖量高低受多种因素影响,而且各种因素间的作用互相制约,错综复杂。据科学实验证明,获得糖产量的关键是生长中叶片截取幅射能总量的多少,其前提条件是在水分和养分充足的情况下。而目前土壤中含有的自然养分是满足不了甜菜生育需要的,因此人工补偿施肥对甜菜的高产、稳产,含糖率的提高和工艺品质的改善等起着重要的作用,但施肥多少,即可达到高产、高糖,又能降低成本,也就是经济效益最佳,这是值得研究的,本文试从以产定肥法谈谈甜菜经济合理施肥方法的运用。
Sugar beet production, the level of sugar content by a variety of factors, but also the role of various factors between each other, complex. According to scientific experiments, the key to obtaining sugar yield is the amount of radiant energy intercepted by growing leaves, provided that the water and nutrients are sufficient. At present, the natural nutrients contained in the soil can not meet the needs of the growth of sugar beet, so artificial compensatory fertilization plays an important role on the high yield and stable yield of sugar beet, the improvement of sugar content and the improvement of process quality. However, To achieve high yield, high sugar, but also reduce costs, that is, the best economic benefits, it is worth studying, this article try to talk about the production of fertilizers to talk about the economic and rational fertilization of sugar beet methods.
