Abstract:
Field experiments have been conducted on soil conditioning agents,effect of the facility vegetable rotations irrigated with salty water on facility vegetable was studied in Tianjin Binhai New Area.Grey relational analysis and the single factor correlation analysis were adopted to analyze soil；crop and other indicators data of facility vegetable irrigated with salty water and applied soil conditioners.The results showed that regarding vegetable cropping systems irrigated salty water，for the cucumber-celery rotation with fresh water and salty water irrigation frequency ratio of 1∶4，the application of soil conditioner and soil conditioner Ⅲ could reduce accumulation of soil salts；for tomatoescelery rotation with fresh water and salty water irrigation frequency ratio of 1∶2，the application of soil conditioner Ⅲ could reduce the accumulation of soil salts.Application of soil conditioner Ⅰ and soil conditioner Ⅲ was able to improve the output value of vegetables irrigated saltwater.Application of soil conditioner Ⅰ and soil conditioner Ⅱ were able to improve vegetables vitamin C content，vegetables soluble sugar content，and also help to improve the relative chlorophyll content of vegetables.The results of grey correlation analysis also showed that the cucumber-celery rotation irrigated with salty water under soil conditionerⅠ，and soil conditioner Ⅲ，the weighted correlations were 0.69 and 0.63，arithmetic correlations were 0.73 and 0.63；the tomatoes-celery rotation irrigated with salty water under soil conditioner and soil conditioner Ⅲ，the weighted correlations were 0.55 and 0.60，arithmetic correlations were 0.59 and 0.59.On the whole，soil conditioners were able to improve production of facility vegetables，improve quality of facility vegetables，and also reduced the accumulation of salts in the soil.
