Effects of different treatments on soil physicochemical properties and fruit quality of strawberry continuous cropping in greenhouse
In order to investigate the effects of different treatments on soil and fruit quality of continuous cropping of strawberry in greenhouse,the effects of seven different remediation techniques,including sweetcorn rotation,cotton shoot disinfection,biochar utilization and fungus residue soil mixing,as controls to investigate the effects on soil physicochemical properties,plant growth,fruit quality and yield after treatment were studied.The results showed that sweetcorn rotation treatment(T1)had the highest soil moisture content and bulk density,and the lowest EC value.And the nutrient content was the lowest,except for total nitrogen,total potassium,alkali hydrolyzed nitrogen,and available zinc content.And all salt ion contents were lower than CK.Wheat straw charcoal treatment(T3)soil water content and bulk density were lower,EC value was the highest,and pH value was higher than CK.The contents of organic matter,total phosphorus,available phosphorus,copper and zinc were the highest.In addition,the content of salt ions was higher than CK,except F and Cl.The growth and development indicators of plants treated with T1 were higher than those of CK.T1 treatment had higher single fruit weight,single plant yield,higher fruit hardness,higher soluble solid content,and the highest sugar acid ratio and solid acid ratio.In conclusion,T3 treatment effectively improved soil compaction and acidification,reduced nutrient loss,and improved fruit quality.T1 treatment had the characteristics of good soil water retention and high soil nutrient utilization rate,which can consume some excess nutrients,thereby reducing soil eutrophication and slowing down secondary salinization of continuous cropping soil.T1 treatment was beneficial to promote the healthy growth of plants,improve fruit quality and yield.
