甘蔗(Saccharum officinarum)品种赣蔗14号,栽培在装有用蒸馏水和氮、磷、钾、铁、锰等试剂配成的多元素中性营养液的塑料盆中,施加不同量的多硅酸盐,试验在温室中进行。光合作用强度和叶绿素含量测定按华东师范大学生物系植物生理教研组主编的《植物生理学实验指导》(1980年,人民教育出版社)的方法进行。测定硅含量时,取蔗叶全叶,洗去表面沾污物,擦干后除去中脉,剪碎,置60～65℃下烘 Sugarcane (Saccharum officinarum) variety Gan sugarcane 14, cultivated In a plastic pot containing a multi-element neutral nutrient solution dubbed distilled water and nitrogen, phosphorus, potassium, iron, manganese and other reagents dubbed different amounts of polysilicate The experiment was carried out in a greenhouse. The photosynthesis intensity and chlorophyll content were measured by the method of “Plant Physiological Experiment Guide” (1980, People’s Education Press), edited by Plant Physiology Teaching and Research Group, Department of Biology, East China Normal University. Determination of silicon content, take the leaves of cane leaves, wash away the surface contaminants, remove the dry mouth, cut, set to 60 ~ 65 ℃ under the roasting
