Effect Of Hydroponic On The Growth Of Strawberry Of Different Varieties

Effect of nutritional formula and concentration different concentrations and different cultivated methods on the growth of different varieties strawberry were studied. The results showed that:l.The experiment of formula and concentration selected and used three nutritional formulas that are Yamazaki nutrient solution formula of strawberry、Hoagland and arnon formula、improved formula,and three nutrient solution concentrations,and three varieties that are tongziyihao. saiwa、hongyan.The results were as follows:(1)In the three nutritional formulas,Yamazaki nutrient solution formula is best appropriate for the growth of strawberry,Hoagland and arnon formula is the worst.(2)in the three varieties,saiwa is the best,hongyan following,tongziyihao is the worst;in Yamazaki nutrient solution formula,1.5times concentration of nutrient solution is best for every index of tongziyihao except root length、root number、rootshoot ratio,1.0times concentration of nutrient solution is more suitable for the growth of saiwa,0.5times concentration of nutrient solution is more suitable for the growth of hongyan.2.The experiment of effect of different cultivated methods and different nutrional concentrations on the growth of different varieties selected and used two cultivated methods that are barrel type cultivation and tubular cultivation and three varieties that are tongziyihao、 saiwa and hongyan and three nutrient solution concentrations,and usedYamazaki nutrient solution formula. The results indicated that:(1)in two cultivated methods,barrel type cultivation is more appropriate for the growth of saiwa than tubular cultivation,but organic acid of it is contrary,and the contrary is hongyan;barrel type cultivation is more appropriate for the growth of tongziyihao than tubular cultivation,but leaf number of it is contrary.(2)in three varieties,the growth of saiwa is better than two others varieties,but quality of fruit of hongyan is better than two others varieties except VC.(3) in three nutrient solution concentrations, about vegetative growth index,effect of different nutrient solution concentrations on different vegetative growth index is different.0.5times concentration of nutrient solution is more suitable for the growth of root length、root number、petiole long of tongziyihao,1.0time concentration of nutrient solution is more suitable for the growth of stem diameter of it,1.5times concentration of nutrient solution is more suitable for the growth of others vegetative growth index of it.1.0times concentration of nutrient solution is more suitable for the growth of vegetative growth index of saiwa except stem diameter and petiole long.0.5times concentration of nutrient solution is more suitable for the growth of vegetative growth index of hongyan except stem diameter.②About reproductive growth、numbers of result、chlorophyll relative content、quality of fruit,1.5times concentration of nutrient solution is more suitable for the growth of tongziyihao,1.0times concentration of nutrient solution is more suitable for the growth of saiwa,1.0times concentration of nutrient solution is more suitable for the growth of thongyan.The growth of different varieties strawberry in different nutrional formula and concentration and cultivated methods showed tremendous difference.
