近年来,随着科学技术的发展,国内外对微量元素的研究普遍受到重视,并做为一种肥料(即微量元素化肥)应用于作物生产,收到一定的增产效果。为了明确在甜菜上的增产增糖作用,以及与我区出现的低产低糖的关系,我们曾对硼、锰、锌、钼和铜等元素的作用,进行了初步研究,现将历年(1972——1978)试验研究的结果综合如下,供参考。
In recent years, along with the development of science and technology, the research of trace elements both at home and abroad has been paid more attention and applied to crop production as a kind of fertilizer (ie, trace element fertilizer), which has received a certain stimulation effect. In order to clarify the effect of increasing sugar gain on sugar beet and its relationship with low yield and low sugar in our region, we have carried out preliminary studies on the effects of elements such as boron, manganese, zinc, molybdenum and copper. -1978) The results of the pilot study are summarized below for reference.
