不同植物生长调节剂对茄子产量和品质的影响

Effect of fulvic acid, DA-6,NAA and sodium nitrophenolate on the eggplant yield and quality

为研究不同植物生长调节剂对茄子产量和品质的影响,设6个处理随营养液灌根,温室生长100 d后测定植株地上部生长指标和光合指标,成熟后测定地下部生长指标、果实产量和品质。结果表明,5%黄腐酸、0.01%DA-6和0.02%复硝酚钠处理均不同程度地影响了茄子的产量和品质,黄腐酸分别与DA-6和复硝酚钠复配使用效果优于单独使用,且相对于对照和其他处理而言,5%黄腐酸与0.01%DA-6复配处理显著提高了植株的茎粗、叶面积、叶片数、根长、根系干重、根系活力、净光合速率、蒸腾速率、气孔导度、叶绿素、果实数量、茄子产量以及Vc、粗纤维、粗蛋白含量,且产量比对照提高30.7%。

In order to study the effect of plant growth regulator treatments on the yield and quality of eggplant six plant growth regulator treatments which irrigated with the nutrient solution to eggplant root were designed, and the photosynthetic, growth indicators, below-ground growth indicators, yield and quality when the plant had grow 100 days and grown maturity in the greenhouse. Results showed that 5% fulvic acid, 0.01%DA-6 and 0.02% sodium nitrophenolate had different effects on the eggplant yield and quality. The effect of fulvic acid compounded with DA-6 or sodium nitrophenolate was better than alone. The plant stem diameter, leaf area, eaf number, root length, root dry weight, root activity, net photosynthetic rate, transpiration rate and stomatal conductance, chlorophyll, fruit number, yield, Vc content, crude fiber and crude protein content improved significantly, especially the yield increased 30.7% compared to the control by using 5% fulvic acid compounded with 0.01% DA-6.
