摘要
【目的】研究各施肥处理对基质栽培樱桃番茄生长、产量、品质以及植株叶片光合和植株养分积累的作用.【方法】以‘千禧’樱桃小番茄为试材,采用基质栽培方式,以试验当地无机肥料施肥量为对照,在对照基础上配合施用生物有机复合肥料T_1(N-P-K=1-7-2)、T_2(N-P-K=1-3-3)和磷矿粉T_3、钾矿粉T_4.【结果】1)T_2处理显著增加植株株高、茎粗、节位数和根冠比;2)T_2处理可显著增大气孔导度、增加胞间CO_2浓度,较CK显著提高植株叶片净光合速率19.2%;3)T_2处理显著影响植株N、P、K积累量;4)T_2、T_3、T_4处理产量分别为80.7、72.3和75.5t/hm^2,分别较CK显著增产16.1%、4.0%和8.6%;5)4组处理均能提高果实Vc和可溶性固形物含量,降低有机酸含量;T_2处理下显著提高番茄可溶性糖含量.【结论】生物有机肥T_2处理能显著影响植株生长、提高樱桃番茄产量和果实品质,另外,钾矿粉T_4作用优于磷矿粉T_3.
【Objective】To research the effect of fertilization treatments on growth,yield,quality and photosynthesis and nutrient accumulation in different plant organs of cherry-tomato.【Method】Taking cherry-tomato‘Qianxi＇cultivated in substrate as the material,fertilized two kinds of bio-organic fertilizer T1（N-P-K=1-7-2）and T2（N-P-K=1-3-3）and other two kinds of mineral powder T3（PP）and T4（PBMB）with local fertilization quantity of inorganic fertilizer as the control（CK）.【Result】Plant height,stem diameter,number of nodes and root-shoot ratio of T2 significantly increased compared to CK.T2 enlarged stomatal conductance and increased intercellular CO2 concentration significantly,improved net photosynthesis rate of plant leaves by 19.2% than that of CK and significantly affected N,P and K accumulation.The yield of T2,T3 and T4treatment was 80.7t/hm^2,72.3t/hm^2 and 75.5t/hm^2,respectively,and significantlyincreasing the yield by 16.1%,4.0%and 8.6%than CK.Four treatments all increased Vc and soluble solids content of fruit and decreased organic acid content.The content of soluble sugar increased significantly under T2 treatment.【Conclusion】Bio-organic fertilizer T2 had significant effect on the growth of cherry tomato and increased production and fruit quality and T4（PBMB）had better effect than T3（PP）.
