【摘要】 2009年采用5个种植密度对安玉13产量经济性状的影响进行了研究,结果表明,(1)不同种植密度显著影响产量经济性状,密度间F值达极显著差异;(2)A3、A4、A5的株高、穗位高随密度的增加逐渐增加;茎粗、穗长、穗粗、穗粒数随密度的增加逐渐减少;病害、空株率、倒伏倒折逐渐加重;(3)A2是最适宜种植密度。更多还原

【Abstract】 A study on economic yield traits was conducted using Anyu13 planted at A1,A2,A3,A4 and A5 5 kinds of densities in the year 2009.The results showed that(1) The economic yield traits of AnYu13 were high significant by different planting densities. (2) The plant height and ear height were increased gradually with the increment of the plantting density,and that were reduced gradually with the increment of the plantting density on the ear length,ear diameter,kernel rate,stalk diameter,ear kernel nember,ear rows, 1000-kernel weight planted at A3、A4 and A5 3 kinds of densities,and that were More and more serious on the disease,No ear rate and The plant pours to break the rate.(3) The A2 is the most suitable planting density of AnYu13 properly.更多还原
