近廿年来美国北卡罗里纳州阿配克斯市研究发展了一种称为“镁碳酸合剂”(MagCarPIus)的产品,可用来提高田间烟草的产量和质量。所根据的原理如下:大部份的镁是以不可溶的氧化镁形式存在于土壤团粒中,通常一株迅速生长的植物需要在叶子内产生一种物质以提供根部去转化氧化镁,使之成为可溶的碳酸盐形式,20年来的研究表明:只有在植株的叶子有力地生长并进行细胞分裂时,根系才能扩展。因此,当植株达到由遗传性和环境条件确定的充分体积时,它从土壤中吸收的镁仅限于小量有效的
In the last 20 years, in the United States, North Carolina, Alexis has developed a product called “MagCarPIus” that can be used to increase the yield and quality of tobacco in the field. The rationale is based on the following: Most of the magnesium is present in soil aggregates in the form of insoluble magnesium oxide, and usually a rapidly growing plant needs to produce a substance in the leaves to provide the root to convert the magnesium oxide Become a soluble form of carbonate, 20 years of research have shown that the root system can only grow when leaves of the plant vigorously grow and divide into cells. Therefore, when the plant reaches a sufficient volume as determined by hereditary and environmental conditions, the magnesium it absorbs from the soil is limited to a small amount of effective
