Effect of different mixed substrates on root restricted cultivation of sweet cherry
This experiment mainly studied the effects of four mixed substrates on the growth po-tential,leaf morphology,photosynthetic characteristics,fruit quality,yield,and soil environment of Brooks sweet cherry trees in root restricted containers,in order to select the suitable substrate formu-la for root restricted cultivation of sweet cherries in southern regions.The results showed that among the four mixed substrates,treatment 3(loess∶organic fertilizer∶pindstrup∶perlite=4∶2∶4∶2)and treatment 4(loess∶organic fertilizer∶pindstrup∶perlite=4∶1∶6∶1)performed better;treatment 1(loess∶organic fertiliser∶pindstrup∶perlite=4∶1∶4∶1)and treatment 2(loess∶organic fertiliser∶pindstrup∶perlite=4∶2∶4∶1)was average.In the mixed substrate required for root limited cultivation of sweet cherries in southern China,the proportion of organic fertilizer should be around 10％,and should not be too high.Pindstrup accounts for 33.33％to 50.00％,and perlite accounts for about 16.67％,which can retain water,fertilizer,and air permeability,and promote the healthy growth and development of sweet cherries.
