| Abstract: |
| Study was made on the effect of potassium nutrition on yield and photosynthesis and economic benefit of edible lily.The result showed that net photosynthetic rate (Pn) and stomatal conductance (Gs) in leaves of edible lily increased notably and transpiration rate (Tr) and intercellular CO2 concentration (Ci) in leaves of edible lily decreased with application of potassium fertilizer within the range of 0～81 kg·hm-2.The stem width and height were significantly increased.The anthesis was ahead of time.The edible lily bulb's yield and economic benefit were increased,too.Compared with CK,when the application rate of K2O reached 81.0 kg·hm-2,the net photosynthetic rate,fresh weight,dry weight,yield and economic benefit of edible lily increased by 19.3%,14.2%,25.0%,14.2%,and 4 times respectively.And under this application rate,both the yield and net photosynthetic rate and economic benefit of edible lily were the highest.The optimum fertilizer potassium level was 81 kg·hm-2 in this study. |
