锰铁氧体纳米材料(MnFe2O4 NMs)的制备及其叶面喷施对番茄品质和产量的影响
Preparation of Manganese Ferrite Nanomaterials(MnFe2O4 NMs)and Effect of Foliar Spraying on Tomato Quality and Yield
摘要
Abstract
Nanomaterials have multiple potentials and applications,with special properties due to their size of less than 100 nm,and have a greater potential for agricultural applications in recent years.In this study,the effect of 1、10、20、30、40 mg·L-1 5 different concentrations of manganese ferrite nanomaterials(MnFe2O4 NMs)on the quality and yield of tomato fruits was investigated by foliar spraying using a small-fruited tomato inbred line'6648'as test material.MnFe2O4 NMs were sprayed for four consecutive days 30 days after tomato planting(one week before flowering),and an equal amount of deionized water was sprayed as a control.The results showed that foliar spraying of MnFe2O4 NMs had a significant effect on improving the growth potential of tomato plants,and also induced a significant effect on the accumulation of biomass;at the same time,it could increase the content of soluble sugar,lycopene,VC,and the sugar-acid ratio content of tomato fruits,which further improved the quality of tomato fruits;and it also had a significant effect on the increase of the yield of tomato fruits.The results of the study also showed that at low concentrations of MnFe2O4 NMs(1-10 mg·L-1),the growth of tomato plants was significantly promoted,and the effect was not significant or even negative at higher concentrations.The total tomato yield increased by 12.7％with the application of 1 mg·L-1 MnFe2O4 NMs.Also analyzed by polynomial fitting,the concentration of MnFe2O4 NMs in the range of 4.01-7.25 mg·L-1 was found to be more effective in improving the growth and quality of tomato.This study provides some reference for the application of nanomaterials on tomato.关键词
