玉米品种密度试验研究

Experiment Study on Planting Densities in Maize

作物品种是影响作物产量的主要因素。通过研究在子洲的川地上,7个玉米品种在3000株·667m^(-2)、4000株·667m^(-2)、5000株·667m^(-2)和6000株·667m^(-2)这四个密度的农艺性状和产量等。研究表明:陕单8806在4000株·667m^(-2)下获得较高产,陕单636、陕单650、郑单958、陕单609在5000株·667m^(-2)的密度下产量最高,登海9号和东单60在6000株·667m^(-2)下产量最高。

Crop varieties are the main factor infecting crops yield.The agronomic traits and yield of the maize under four planting densities of 3000 plants·667m^(-2),4000 plants·667m^(-2),5000 plants·667m^(-2)7 and 6000 plants·667m^(-2)were studied in river valley areas of Zizhou county.The results showed that‘Shandan8006’had the highest yield under density of 4000 plants·667m^(-2),‘Shandan 636’,‘Shandan 650’,‘Zhengdan 636’and‘Shandan 609’had the highest yield under density of 5000 plants·667m^(-2),‘Denghai 9’and‘Dongdan 60’had the highest yield under density of 6000 plants·667m^(-2).
