密度对织金3号产量的影响

Effects of Planting Density on Yield of Zhijin No.3

为探索适宜织金3号的种植密度,进行了5个不同密度的比较试验。结果表明:织金3号株高、穗长、茎粗、穗位高、穗行数、行粒数均随密度的增加而降低,秃尖长度随密度增加而变长。单产以密度为4000株/667m^2最高,达753.72kg/667m^2,密度增加或者降低单产均有所减少。

To explore appropriate planting density of Zhijin No. 3,5 different planting densities were studied. The results showed that with the increase of the planting density, the plant height, corncob, diameter of corncob, corncob height, rows of corncon, grains per row of corncon of Zhijin No. 3 increased, but the tip of corncon decreased. The yield of corn at 4000 plants/667m2 was greatest, it＇ s 753.72kg/667m2 ,with the increase and decrease the planting density, the yield trends decease down.
