不同播种密度与播种质量对红葱生长及产量的影响

Effects of Different Sowing Densities and Qualities on Growth and Yield of Shallot

以红葱为试材,采用2因素3水平正交实验设计,在不同播种密度(15、25、35粒·穴^(-1))和播种质量(0.5、1.5、2.5g·粒^(-1))处理条件下对红葱出苗率、株高、假茎粗、叶片数及分蘖数进行分析,研究了不同播种密度和播种质量对红葱生长及产量的影响。结果表明:不同播种密度和播种质量对红葱出苗率、株高、假茎粗、叶片数、分蘖数及产量均有显著影响。当播种密度为25粒·穴-1时,播种质量为2.5g·粒^(-1)时,红葱生长较好,红葱单位面积产量最高,适宜在宁夏地区推广种植。

Shallot was used as material,the experiment was conducted with 2 factors and 3 levels orthogonal design.The seedling emergence rate,plant height,stem diameter,leaf number and tiller number were analyzed under different sowing densities（every hole of 15,25,35grain）and sowing qualities（every grain of 0.5,1.5,2.5g）.The effects of sowing density and quality on the growth and yield of shallot were studied.The results showed that the sowing rate,plant height,stem diameter,leaf number,tiller number and yield were significantly affected by different densities and qualities.When sowing density was every hole of 25 grain,when sowing quality was 2.5g per grain,shallots growed better,shallot yield per unit area was the highest and suitable for planting in the local of Ningxia.
