Effect of N、P、K balance fertilization on the seeds yield and yield components of Dactylis glomerata
The response of seeds components and yield of D. glomerata to fertilization treatments with differing N : P : K ratios in was studied at an experiment farm of Baoxing, in the Baoxing county of Sichuan, from 2001 - 2003. The results indicated that the optimum applied equilibrium fertilization was 3 : 1 : 2 (N 120 kg/hm2 + P 40 kg/hm2+K 80 kg/hm2). Further, the results showed their was an obvious correlation between seeds yield and yield components for the equilibrium fertilization. Seeds per flower was primarily correlated with the seeds yield. The major seeds yield components in order of decreasing importance were :Seeds per floweret> seeds per spikelet > fertile tillers> spikelets per fertile tillers.
