Effects Of Different Plant Growth Regulators On The Flowering And Flourishing Control Of Cherry Tomato

In this experiment,different plant growth regulators were used to spray on tomato plants to study their effects on promoting flowering and controlling flourishing of tomato,and to explore their effects on growth index,yield and quality of tomato,so as to provide theoretical basisi for future production practice.The test results are as follows:1.The effects of different plant growth regulators on cherry tomato flower growth were studied:there were five treatments for flower promotion:cytokinin(A1),95%Paclobutrazol(A2),yuhualing(A3),2,3,5-Triiodobenzoic acid(A4),flowering essence(A5),and CK.The results showed that five plant growth regulators had obvious inhibitory effect on the growth of tomato seedlings,but the inhibitory effect gradually weakened after planting,and the growth of each treatment was stronger than that of the control at 63d after planting.From the aspect of yield,the yield of fA5(lowering sperm)is higher.From the aspect of quality index,A1(cytokinin)and A5(flowering sperm)have better promoting effect on quality.The content of soluble sugar and soluble solid is higher,the content of organic acid is lower than that of the control,the content of VC is higher from the first ear to the second ear,and the ratio of sugar and acid of A5(flowering sperm)is significantly different from that of the control,which is suitable for popularization and application.2.The effects of different plant growth regulators on the control of cherry tomato:there were five treatments for the control of cherry tomato:chlorophyll(T1),Yangcai(T2),huaguoan(T3),aizhuang(T4),propiconazole(T5)and CK.The results showed that in the current tomato production,all treatments had significant inhibition on the growth of tomato seedlings,but the most obvious effects were T1(chlorophyll)and T4(chlorpromazine).In terms of tomato quality,T1(chlorophyll),T2(Yangcai)VC,soluble sugar and soluble solids are relatively high,which can be used to improve the quality of tomato,and is suitable for popularization and application in tomato seedling production.In terms of yield,the yield of chlorophyll(T1)and huaguoan(T3)is higher,which is suitable for popularization and application.
