缺硼土壤使用硼肥,可显著提高红三叶草地上部植株蛋白氮和非蛋白氮以及根中非蛋白氮含量;叶片中游离氨基酸和水解氨基酸也因种类不同而对硼的反应有较大差异;施硼还能促进结瘤、固氮和萌发种子中蛋白酶、肽酶的活性。
The use of boron fertilizer in boron-deficient soil could significantly increase the contents of protein nitrogen, non-protein nitrogen and non-protein nitrogen in the roots of red clover, but the differences of free amino acids and hydrolyzed amino acids in leaves were also different for boron. Boron can also promote nodulation, nitrogen fixation and germination of protease, peptidase activity.
