Abstract
Through effect experiment of different planting patterns,planting density and fertilization modes on yield and quality of Bingdan 669,the results showed that the yield,fertilizer benefit and net income of new maize variety Bingdan 669 are the highest on72 000 plants/hm2wide-narrow row and N2P2K2(350-100-80 kg/hm2)fertilization level;the fertilizer use efficiency is the highest on72 000 plants/hm2wide-narrow row and N1P1K1(280-72-75 kg/hm2)fertilization level.The absorption of nitrogen,phosphorus and potassium content is the lowest to yield 100 kg seeds.Base on different planting patterns,planting density and fertilization level,the maize grain abtains is the highest starch content on the N2P2K(2350-100-80 kg/hm2)fertilization level.It shows that the most appropriate planting pattern of the maize variety Bingdan 669 is wide-narrow row planting;the best planting density is 72 000 plants/hm2 and the most appropriate fertilization level is N22P2K(2350-100-80 kg/hm).This will provide the theoretical basis and guidance for reasonable utilization and extension of new varieties Bingdan 669.
