| 摘 要： | 固氮蓝藻(cyanobacteria)能将空气中的游离氮(N2)转化为氮素化合物。为探讨固氮蓝藻在稻田中作为肥料的应用效果,进行了稻田施用固氮蓝藻及常用化肥(尿素)的对比试验研究。结果表明,虽然施用固氮蓝藻的水稻前期长势不如施用化肥见效快,但其具有持续稳定的作用,可协调产量因子,起到显著增产效果,且鲜藻的效果比干藻尤为明显。

| Abstract: | Cyanobacteria can easily take use of the nitrogen by transforming the dissociable nitrogen into nitrogenous combination. If we fertilized the rice field via nitrogen-fixing blue-green algae, it would be a bonanza of benefits for us. We compared the different effects when the different fertilizers were applied. The result indicated that the effect of nitrogen-fixing blue-green algae wasn't as fast as the fertilizer at the beginning of the rice, but it had the advantage durative to increase the yield by adjusting the yield components of rice, and effect of fresh algae was better than dry algae. Therefore, nitrogen-fixing blue-green algae will be able to become the important biological nitrogenous fertilizer in rice areas. |
