Abstract:: Under plastic tunnel，using ‘Jersey knight’ Asparagus officinalis L.seeds as material，the effect of yield and nutrient quality of Asparagus officinalis L.spear with different fertilizer combination application according the ‘3414’ experiment design were studied.The results showed that with the increase of nitrogen fertilizer used，the yield showed a trend of slow increase；and with the increment of potassium fertilizer application，the yield was reduced after the first increased trend.There was no significant interaction effect between nitrogen and potassium.Asparagus officinalis L.production was more sensitive to potassium fertilizer，which had the negative effect on Asparagus officinalis L.yield during the potassium reached certain amounts.The N1P2K1 treatment (Treatment 9) had the highest yield and best appearance quality than any other treatments.And N2P2K2 treatment (Treatment 6) showed the lowest crude fiber content and high content of rutin and saponin，which had the highest nutritional quality and the best taste rutin and ginsenoside content were 0.65 mg/g and 26.23 mg/g.After regression analysis by fertilizer model，the suitable fertilization combination could be calculated as following,nitrogen fertilizer for 33.98 kg urea，26.67 kg calcium superphosphate and 28.78 kg potassium sulphate per 667 m2.
