为比较不同腐殖酸量对水稻(Oryza sativa L.)生长生理的影响,在随机组合的盆栽和大田土壤中分别施入0,0.1,1,10 g/m~2的腐殖酸进行试验。结果表明:在盆栽条件下,腐殖酸增加水稻抽穗期剑叶的净光合速率、胞间CO_2浓度、气孔导度、蒸腾速率和SPAD值,也增加稻米Cu,Fe,Mn,Zn,S,K,P,Mg和Ca含量。剑叶净光合速率既与稻米Mn,Zn,Ca,P和(Cu+Fe+Mn+Zn)含量呈多项式正相关,又与稻米S含量呈线性正相关。在大田条件下,腐殖酸显著增加水稻产量(P

In order to compare the effects of humic acid contents on the growth and physiology of rice （ Oryza sativa L. ）, four treatments of 0, 0. 1, 1 and 10 g/m2 humic acid were respectively applied into the pot and field experiments. The results showed that humic acid could increase net photosynthetic rate, intercellular CO2 concentration, stomatal conductance, transpiration rate and SPAD value in flag leaf at heading stage, and increase the contents of essential elements （Cu, Fe, Mn, Zn, S, K, P, Mgand Ca） in rice in the pot experiment. The net ...
