不同有机物料对设施番茄生长、产量和品质的影响OA

To clarify the application effects of different organic materials in facility tomato cultivation,this study used the cultivar'Jingcai No.8'as the test material and set up four treatments:control(CK),straw(SC),compost(CC),and humic acid fertilizer(HC),to explore the effects of different organic materials on the growth,yield,and quality of facility tomatoes.The results showed that the SC treatment increased tomato plant height,leaf number,and maximum leaf area,as well as improved root length and root surface area.The CC treatment increased root volume and root surface area.All three organic materials enhanced the biomass of tomato plants(roots,stems,fruits,aboveground parts,and total biomass),with the SC treatment performing the best.Compared with the CK,the yields of the SC and HC treatments were significantly increased by 49.25%and 24.62%,respectively.Compared with the CK,the SC treatment significantly increased the soluble sugar content and sugar-acid ratio of tomato fruits,and the CC treatment significantly increased the organic acid content,while the HC treatment significantly increased the soluble sugar content.Compared with the CK,the tomato quality index of the SC and HC treatments were significantly increased by 340.29%and 123.47%,respectively.In conclusion,the application of straw can effectively promote the growth of facility tomatoes,and has the best effect on improving yield and quality.
