Abstract:
Abstract:Taking Datong daylily (Hemerocallis citrina Baroni) as the test material,field experiments were conducted to investigate the effects of different N levels of P and K fertilizers on the growth，photosynthetic characteristics，and yield of yellow cauliflower compared to farmers′ customary fertilization，in order to obtain the optimal N application amount during the bolting period，provide reference for scientific and reasonable fertilization of yellow cauliflower.The results showed that the yield increase effect of applying P and K fertilizer in bolting stage was better than that of applying N fertilizer alone.From the perspective of photosynthetic characteristics，the application of N 7.5 kg per 667 m2,P2O5 4.5 kg per 667 m2,K2O 14 kg per 667 m2 was the best.From the perspective of agronomic indicators of daylily，fertilization in bolting stage was mainly to increase the yield of daylily by increasing the number of bolting，the number of flower buds per bolt and the weight of bud.When the amount of N fertilizer was 15 kg per 667 m2，the yield of fresh and dry vegetables of daylily reached the highest，with an average yield of 1 760.26 kg per 667 m2 and 228.74 kg per 667 m2 dried vegetables increased by 45.43% and 42.81% respectively compared with the blank.The amount of N fertilizer recommended by the unitary quadratic fertilizer efficiency equation was similar to the optimal amount
