Abstract:
The main strawberry varieties planted in facilities，‘Tian Chali’ and ‘Hongyan’，were used as test materials.Yellow sand ridge cultivation mode was used.Taking traditional soil ridge cultivation mode as a control，facility strawberry yellow sand substrate water and fertilizer integrated technical system was established，the effects of yellow sand substrate cultivation on plant growth，leaf photosynthetic characteristics，fruit yield and quality of facility strawberry were studied,in order to povide a reference for questions such as continuous cropping obstacles and decline in strawberry yield and quality caused by continuous planting of facility soil，soil-borne diseases occur frequently.The results showed that with yellow sand as cultivation substrate combined with water and fertilizer integrated equipment，strawberries grew well throughout the growing period.At maturity，the number of leaves，petiole length，dry weight and fresh weight of aboveground and underground of the two strawberry varieties under yellow sand cultivation conditions were significantly higher than that of soil cultivation；the SPAD values of ‘Tian Chali’ and ‘Hongyan’ strawberry leaves both peaked at the flowering and fruiting stage，and yellow sand cultivation was significantly higher than soil cultivation by 5.91% and 6.83%，during the flowering and fruit setting period，the net photosynthetic rate (Pn），stomatal conductance （Gs），intercellular CO2 concentration （Ci） and transpiration rate （Tr） of the strawberry leaves of ‘Tian Chali’ and ‘Hongyan’ cultivated by yellow sand cultivation were significantly higher than that of soil cultivation by 8.33%，56.52%，5.91%，17.50% and 8.49%，54.55%，5.35%，20.62%；from the perspective of yield and quality，compared with soil cultivation，the fruit diameter，yield and soluble solid content of the strawberry fruits of ‘Tian Chali’ and ‘Hongyan’ cultivated by yellow sand were significantly increased by 28.29%，26.69%，29.82% and 26.18%，20.79%，26.02%.It could be concluded that the ridged cultivation model of facility yellow sand could use yellow sand as the cultivation substrate to plant strawberries，it was a facility soilless cultivation model that could promote the growth of strawberry plants and increase yield of strawberry，it was suitable for popularization and application in facility high-yield cultivation of strawberry in the Gobi Desert of Hexi.
