云大-120对番茄生长发育及果实品质的影响

试验结果表明:日光温室番茄定植后,叶面喷施3次云大-1201500倍液效果最好。其中,株高和茎粗的净增长量分别比对照增加17.0%和35.0%;座果率、单果重和前期产量分别提高14.7%、23.2%和24.6%;叶片光合速率提高15.8%;果实可溶性固形物和Vc含量分别提高26.7%和24.7%;滴定酸含量降低13.9%。

Effect of Yunda-120 on Tomato Plant Growth and Fruit Quality

Yunda-120 solution was sprayed on the leaves of tomato planted permanently in greenhouse. The results showed that, among all of the treatments, 1500 times of Yunda-120 solution sprayed for three times was the best treatment. Compared with the contrast, the net increments of plant height and stem diameter were increased by 17.0 % and 35.0 % respectively, the ratio of fruit-setting, the weight of per fruit and yield at the earlier stage were raised by 14.7 %, 23.2 % and 24.6 % respectively, the photosynthetic rate was increased by 15.8 %, the content of soluble starch and vitamin C of fruit were raised by 26.7 % and 24.7 % respectively, and the content of titration acid was decreased by 13.9 %.
