硼在一些高度分化的沙土上发生缺硼。在美国缺硼一般并不降低产量而使作物品质有所下降。缺硼种子并没有专门的形状。子叶内面凹陷而失色,这就是所谓“空心”的内部受害状。关于这问题早先的工作是由Harris及其同事在佛罗里达开展的。 Boron deficiency occurs on some well-differentiated sand. The lack of boron in the United States generally does not reduce the yield of crops and the quality is somewhat reduced. The lack of boron seed does not have a special shape. Cotyledons inside the depression and pale, which is the so-called “hollow” internal victim. Earlier work on this issue was conducted in Florida by Harris and colleagues.
