甜菜在我中部地区栽培由于便利作物茬口安排,多采用夏季播种。可是夏播甜菜往往出现高青顶的现象,影响甜菜块根的制糖工艺品质。根据各地的报导,各年高青顶的发生率视当年当地的气候环境条件不同而有较大的差异。因此分析到研究甜菜高青顶发生的原因以及针对其我国提出控制的方法,在生产上有一定的重要意义。我们分析夏播甜菜所处的特点气候条件,认为以下几种因素(或者各因素间的交互作用)可能是形成高青顶的原因,值得加以研究,即①高温,②长日照,③高强光,④过多的土壤水分,⑤一定的苗令。
Beets are cultivated in the central part of my country Thanks to the convenient arrangement of crops and stubble crops, summer planting is the common method. However, summer beet often appear high green top phenomenon, affecting sugar beet root sugar quality. According to reports from all over the world, the prevalence of high peak in each year varies greatly depending on the local climatic and environmental conditions in that year. Therefore, it is of great importance to study the causes of the high beet and the methods of controlling it proposed in China. We analyze the summer weather beet where the characteristics of climatic conditions, that the following factors (or the interaction between the factors) may form a high green top reason, it is worth to be studied, namely ① high temperature, ② long sunshine, ③ high light, ④ excessive soil moisture, ⑤ certain Miao Ling.
