过去,国内外曾有过一些喷施腐植酸钠提高旱土作物产量的报道。我们也曾观察到它能促进小麦提早成熟的现象。但腐植酸钠对提高水稻产量作用的报道甚少。1975—1978年,我们对水稻生育后期喷施腐植酸钠的增产效果及生理作用机制,进行了一些研究,现将研究结果报告于后。 试验材料和
In the past, there have been reports of spraying sodium humate at home and abroad to increase the yield of dry land crops. We have also observed that it can promote the premature ripening of wheat. However, there are few reports on the effect of sodium humate on improving the yield of rice. From 1975 to 1978, we conducted some researches on the effects of spraying sodium humate on the growth and physiological mechanism of rice in the late growth stage, and the results are reported hereafter.
