不同外源性植物激素混剂对水稻育秧进行应用研究,试验结果表明:(1)浸种育秧方式:水稻秧苗假茎宽和株平均根数比对照高3.2%～35.5%和2.1%～41.2%;喷苗池育秧:水稻秧苗假茎宽高于对照22.6%～48.4%;(2)浸种和喷苗池育秧:水稻秧苗叶片数比对照高1.4%～37.9%和13.6%～19.1%,剑叶宽度均高于对照;(3)浸种和喷苗池育秧;水稻秧苗株鲜重、干重分别比对照提高21.1%～86.7%、14.1%～101.6%和52.3%～63.9%、64.1%～98.4%;(4)提高了水稻秧苗内含物,浸种和喷苗池育秧,水稻秧苗中叶绿素、可溶性糖、游离脯氨酸含量分别高于对照15.4%～95.4%和36.4%～83.1%、6.1%～178.8%和18.2%～75.7%、7.9%～189.3%和77.1%～234.3%;外源性植物激素混剂能健壮水稻秧苗.
The results showed that: (1) Soaking seedling method: the average number of pseudostem width and average number of shoots of rice seedlings were 3.2% ~ 35.5% and 2.1% ~ 41.2% higher than that of the control, respectively. ; Seedling pond seedling raising: the pseudostem width of rice seedling was 22.6% -48.4% higher than that of the control; (2) soaking seedlings and spray seedling pond seedling: the number of rice seedling leaves was 1.4% -37.9% and 13.6% -19.1% Leaf width were higher than that of the control; (3) Seedling and seedling pool seedling raising; fresh weight and dry weight of rice seedling increased 21.1% ~ 86.7%, 14.1% ~ 101.6% and 52.3% ~ 63.9%, 64.1% 98.4%; (4) The contents of chlorophyll, soluble sugar and free proline in rice seedling seedlings were increased by 15.4% -95.4% and 36.4% -83.1% 6.1% -178.8% and 18.2% -75.7%, 7.9% -189.3% and 77.1% -234.3%, respectively. Exogenous phytohormones can strengthen rice seedlings.
