镁是叶绿素的构成元素,位于叶绿素分子结构的卟啉中间,叶绿素可以吸收光能,促进碳的同化。据资料介绍,各种作物对镁的需求不同,其增产效果也不一致,其中豆科作物增产效果较稳定。为了探索镁肥的有效施用条件与方法,1995～1996年,我们在大豆主产区的东宁镇,以当家品种8502为参试
Magnesium is a constituent element of chlorophyll, which is located in the middle of porphyrin with the molecular structure of chlorophyll. Chlorophyll can absorb light energy and promote carbon assimilation. According to the introduction of information, the demand of various crops for magnesium is different, and the yield increase effect is also inconsistent. Among them, the yield increase of leguminous crops is relatively stable. In order to explore the effective application of magnesium fertilizer conditions and methods, from 1995 to 1996, we are in the main producing areas of soybean in Dongning Town, with a variety of 8502 as the starter
