摘　　要：采用离子束对哈茨木霉进行注入并筛选出H-13菌株,该菌株发酵液含有对水稻生长有显著促进作用的物质;经对喷施该菌株发酵液后的水稻硝酸还原酶(NR)活力及其N、P和K含量的测定,发现该菌株发酵液促进水稻生长与提高NR活力、增强对N、P和K的吸收有关。The muttagenic H-13 strain which was injected by ionic beam and screened from Trichoderma hamzlaiarum, can promote the growth of rice remarkably. In the experiment, we use zymolytic liquid of H-13 strain sprinkle on the seedling of rice, and determine nitrate reductase activity and N, P, K content. The results suggest that the effect of promoting plant growth of the strain has a relation to the enhance of nitrate reductase activity and the increase of N, P and K absorption.
