Abstract:
Taking cucumber as experimental material,the effects of exogenous silicon application on the growth,fruit yield and quality of continuous cropping cucumber were studied by pot cultivation,in order to provide reference for exploring the application effect of exogenous silicon alleviating cucumber continuous cropping obstacle.The results showed that exogenous silicon application increased plant height,stem diameter,leaf number and biomass of continuous cropping cucumber,and promoted cucumber growth.100,200 mg·kg-1 and 300 mg·kg-1 silicon treatments increased root activity,chlorophyll and carotenoid contents in leaves,and increased net photosynthetic rate of cucumber leaves by 479%,1172% and 657%,respectively.Exogenous silicon treatment significantly increased cucumber yield,and total yield increased by 1109% under 200 mg·kg-1 silicon treatment.The contents of free amino acids,soluble sugar,soluble protein and vitamin C in continuous-cropped cucumber fruits increased under silicon application.Silicon had a positive effect on alleviating continuous cropping obstacle of cucumber.Under the experimental conditions,the growth,fruit yield and quality indexes of continuous-cropped cucumber were improved most significantly by applying 200 mg·kg-1 silicon,and the effect of alleviating continuous cropping obstacle was better.
