应用稀土可使果树增产稀土参与植物生理代谢，能够增加叶绿素的含量，增强光合同比作用，可促进植物生长，增加营养物质积累，促进花芽分化，从而增加经济产量。提高品质，提早成熟。这是包头园林研究所、包头果树研究所等科研单位对稀土应用研究的结果。一、稀土应用技术... Application of rare earth can increase the yield of fruit trees Rare earth participate in plant physiological metabolism, can increase the content of chlorophyll and enhance the role of photosynthesis, can promote plant growth, increase nutrient accumulation, promote flower bud differentiation, thereby increasing economic yield. Improve quality, mature earlier. This is Baotou Institute of Landscape Architecture, Baotou Institute of fruit and other research institutes on the application of rare earth results. First, the application of rare earth technology ...
