微量元素在农作物生育活动过程中起着重要作用。近年来,已(做为一种新型肥料)应用于农业生产的实践中,对提高农作物产量起到很重要的作用。我县是全国甜菜生产重点县份之一。随着栽培技术的改进和化肥施用量的增加,甜菜产量有所提高,但其幅度不大。为了探索提高甜菜产质量简而易行的途径,以期进一步发展我县甜菜生产,我们于一九七八年至一九八一年进行了微量元素对甜菜增产增糖的试验研究。从而明确了不同微量元素对甜菜的效果,以及适宜的施用量、时期和方法,为我县甜菜生产提供了合理施用微肥的依据。
Trace elements play an important role in the process of crop growth and reproduction. In recent years, application of (as a new type of fertilizer) to agricultural production practices has played an important role in increasing crop yields. My county is one of the key counties in the country’s beet production. With the improvement of cultivation techniques and the increase of chemical fertilizer application, the yield of beet has been increased, but its range is not big. In order to explore a simple and easy way to improve the yield and quality of sugar beet, with a view to further developing the sugar beet production in our county, we carried out experimental studies on the sugar content increase of sugar beet with trace elements from 1978 to 1981. Thus the effect of different trace elements on beet was clarified, and the suitable application amount, period and method provided the basis for the rational application of trace fertilizer for the production of beet in our county.
