摘要
对黑龙江省东部淀粉加工企业常用的4个高淀粉中早熟玉米品种在4种不同密度下的淀粉产量进行分析。结果表明,密度直接影响淀粉产量,而不同的品种在不同的密度下有不同的淀粉产量潜力。要获得单位面积上高淀粉产量,建议在我省东部第二、三积温带之间应适当增加密度,最佳密度为5.5万～6.2万株/hm2。
Four high starch and middle-early mature corn cultivars, which wer e used commonly by the starch enterprises in the East of Heilongjiang province, were tested in 4 diffierent densities to analyze starch yields. The result showe d: densities directly effect starch yields of the experimental plots. Increase d ensity adaptly was suggested both in second and third accumulated temperature zo ne in the East of Heilongjiang province, optimum density is 5.5 - 6.2×104 plant s/ha.
