植物的正常生长需要一定量的硼,缺少了硼就会对植物的生长、光合作用、糖的运输和蛋白质合成、核酸代谢等产生一系列影响。但是,植物对硼素的要求不是无限的。如果硼的供应超过了植物正常生长需要量,不但无益,反而有害。农作物对过量硼的反应西安浐河地区某处受工厂排放含硼废物的严重污染,浅层地下水含硼量一般在1.0—37.4毫克/升之间,耕层土壤中可溶性硼含量在3.6 The normal growth of plants need a certain amount of boron, the lack of boron will have a series of effects on plant growth, photosynthesis, sugar transport and protein synthesis, nucleic acid metabolism. However, plant requirements for boron are not unlimited. If the supply of boron exceeds the normal growth needs of plants, not only useless, but harmful. Responses of Crops to Excess Boron The Xi’an Bohe River area is seriously polluted by boron-containing wastes discharged by factories. The content of boron in shallow groundwater is generally between 1.0-37.4 mg / l. The content of soluble boron in the topsoil is 3.6
