甜菜是一种需肥较多的作物,同时对肥料比例要求较为严格。如果比例失调,将对产质量带来不利的影响。当前,我省种甜菜施肥比例失调现象较为严重,偏重氮肥,磷肥施的少,钾肥因没有供应来源也根本不施。这种状况必然使甜菜产质量,达不到我们的要求。为了解决这些问题,我们从1981—1982年开展了氮、磷、钾营养配比的研究,以便为甜菜科学施 Beet is a fertilizer that requires more fertilizer, while the proportion of fertilizer is more stringent. If the proportion of imbalances, will have a negative impact on production quality. At present, our province planted sugar beet fertilization imbalance is more serious, emphasis on nitrogen fertilizer, phosphorus fertilizer less, there is no source of potash fertilizer also simply not Shi. This situation is bound to make sugar beet quality, less than our requirements. In order to solve these problems, we conducted a study on the ratio of nitrogen, phosphorus and potassium nutrition from 1981 to 1982 in order to provide science for sugar beet
