Abstract
Use strawberry cultivar‘Benihoppe’as test material.The purpose of this study was to investigate the relations of K-deficiency stress with continuous cropping obstacles of strawberry.The results showed that the growth of shoot and root was inhibited,when strawberry plants were replanted in first-crop substrates with K-deficiency(K+48.75 mg.L-1),1/2K(K+415.58 mg.L-1)and normal K(K+ 782.41 mg.L-1)treatments compared with control group.The plants with K-deficiency treatment had the worst growth,while the growth of plants with 1/2K treatment was better than that with 1K treatment.Root exudates of second-crop plants with K-deficiency treatment had a significant influence on growth of the tissue cultural plantlets.The low concentration(1%,2%)promoted laterals growth and shoot growth and high concentration(4%)inhibited root growth.When second-crop substrates were used to replant strawberry plants and inoculated by Fusarium oxysporum and Verticillium dahliae,the diseases of third-crop strawberry plants were worse at different periods than that of control group.The disease of plants with K-deficiency treatment was the most serious,resulting in a 75 disease index after 10 days.1/2K treatment had lower disease index than normal K treatment.In conclusion,continuous cropping obstacles of strawberry can be worse under the K-deficiency stress and appropriate K concentration had an important role in preventing continuous cropping obstacles.
