5种叶面肥对大棚草莓光合特性及品质的影响
Effects of five foliar fertilizers on photosynthetic characteristics and fruit quality of Fragaria ananassa in greenhouse
摘要
Abstract
[Objective]The study aims to explore the effects of different foliar fertilizers on the photosyn-thetic characteristics,fruit quality,and yield of greenhouse strawberries,and to screen suitable foliar fer-tilizers.[Methods]The strawberry variety"Monterey"planted in the greenhouse of Moujiatai Strawberry in Xigu District of Lanzhou City,Gansu Province was used as test materials.Under sufficient fertilization,five types of foliar fertilizers,including classic 750 × liquid(T1),Huapu 1 500 × liquid(T2),and Runliang 750×liquid(T3),500 × Adela fruit(T4),and 1500 × potassium dihydrogen phosphate(T5),were ap-plied topdressing at four growth stages,with water as control.The photosynthetic parameters,fruit qual-ity,biomass,and yield were measured.[Results](1)After spraying different foliar fertilizers,the bio-mass and chlorophyll content of strawberry plants were significantly increased,and the net photosynthetic rate and transpiration rate of leaves were significantly increased,while the intercellular carbon dioxide con-centration was higher than that of CK.(2)For fruit quality,T2 and T3 treatments significantly improved the strawberry fruit shape index,while T1 and T5 treatments significantly increased fruit volume and weight.Among them,the average single fruit mass of T1 was increased by 35.04％compared with CK,while the transverse and longitudinal diameters of T5 fruits were increased by 49.39％and 40.64％,re-spectively.(3)The quality of strawberry fruits was effectively improved by various foliar fertilizer treat-ments,and T1 treatment was the best.The content of vitamin C,soluble solids,soluble proteins,reduc-ing sugars,and soluble sugars were increased by 30.84％,33.5％,38.5％,27.9％,and 36.2％,respec-tively,compared with CK.The content of titratable acid was the lowest,and the sugar acid ratio was the highest,with significant difference compared with CK.(4)Spraying appropriate fertilizer significantly in-creased plant biomass,max single fruit weight,and fruit yield;treatment T1 had the highest yield,an in-crease of 13.65％compared with CK.[Conclusion]The application of appropriate foliar fertilizer effective-ly improves the nutritional growth status of strawberries,enhances the quality of strawberry fruits,and significantly increases yield.The comprehensive effect is best when applying classic 750 × liquid.关键词
