Title: The Effects of Sowing Date and Planting Density on the Panicle Traits and Yields of New Maize Variety Hengdan 6272
Abstract: Taking Hengdan 6272 as the test material,the tests of sowing date and planting density were designed using the single factor experiment design,the effects of 4 sowing dates(June 12,June 17,June 22 and June 27) and 5 planting densities(55 500,63 000,70 500,78 000 and 85 500 plants/hm2) on the panicle traits,resistance and yields of Hengdan 6272 were studied in the central and southern part of Hebei Province.The results showed that with the delay of sowing date,the ear length,ear diameter,grain number per row and 1000-grain weight were gradually declined,bald tip length was gradually increased,the resistance was decreased and the yield was significantly decreased.With the increasing of planting density,the ear length,ear diameter,grain number per row and 1000-grain weight were all generally decreased,bald tip length was increased,the resistance was decreased and the yield was increased first and then decreased.It recommended that the suitable sowing date of Hengdan 6272 was June 12-17,the suitable planting density was 63 000-70 500 plants/hm2 in the central and southern part of Hebei Province.
