套餐施肥对莲花白生长、品质及产量的影响

Package Fertilization on the Growth,Quality,and Yield of Cabbage

探讨了黄腐酸套餐施肥A、不含黄腐酸套餐施肥B和常规施肥C对莲花白(Brassica oleracea L.var.capitata)生长,品质及产量的影响,旨在为蔬菜作物套餐施肥提供理论依据和可行性方案。结果表明:莲花白莲座期,套餐施肥A与常规施肥C相比,叶宽、茎粗、鲜重、地上部鲜重,分别增宽12.59%、增粗6.77%、增重34.23%、增重42.44%;套餐施肥B与常规施肥C相比SPAD有显著差异,SPAD值提高6.83%。莲花白结球期,套餐施肥A与常规施肥C相比,地上鲜重、包心鲜重,分别增重71.25%、73.66%;套餐施肥B与常规施肥C相比,地上鲜重、包心鲜重分别增重67.25%、56.42%。莲花白成熟期,套餐施肥A Vc、可溶性糖、地上鲜重、包心鲜重比常规施肥C分别增多8.28 mg/kg、2.21 mg/kg,分别增重28.97%、54.90%;套餐施肥B Vc、可溶性糖、地上鲜重、包心鲜重比常规施肥C分别增多2.41 mg/kg、0.98 mg/kg,分别增重20.56%、39.22%。

The effects of different fulvic acid package fertilizations on the growth,quality and yield of cabbage(Brassica oleracea L.var.capitata)were studied to provide feasible scheme for vegetable crop package fertilization.The results showed that during the cabbage rosette stage,compared with conventional fertilization C,the combination fertilization A increased leaf width,stem diameter,fresh weight,and aboveground fresh weight by 12.59%,6.77%,34.23%,and 42.44%,respectively.Compared with conventional fertilizer C,the SPAD value of combination fertilization B was significantly different,was increased by 6.83%.During the cabbage heading stage,combination fertilization A increased the aboveground fresh weight and pericardial fresh weight by 71.25%and 73.66%,respectively.Compared with conventional fertilization C,the aboveground fresh weight and pericardial fresh weight of combination fertilization B increased by 67.25%and 56.42%,respectively.During the cabbage maturation stage,compared with conventional fertilization C,the combination fertilization A increased Vc,soluble sugar,aboveground fresh weight,and pericardial fresh weight by 8.28 mg/kg and 2.21 mg/kg,28.97%and 54.90%,respectively;The combination fertilization B increased Vc,soluble sugar,aboveground fresh weight,pericardial fresh weight by 2.41 mg/kg and 0.98 mg/kg,20.56%and 39.22%,respectively.
