不同密度和施肥量对糯玉米郑黑糯1号鲜穗产量的影响

Effect of the Different Rates of Fertilizer Application and Densities on Fresh-ear Yield of Waxy Corn-Zhengheinuo No.1

2006年在郑州进行了糯玉米新品种郑黑糯1号肥料密度双因子裂区试验,通过对鲜穗产量、鲜果穗性状和种植效益进行分析比较,结果表明,若以收获鲜穗为种植目的,最佳处理组合为A2B2:种植密度60000株/hm2,施肥量为尿素450 kg/hm2,过磷酸钙450 kg/hm2,氯化钾240 kg/hm2。

The manure-density split plot experiments of new waxy corn variety Zhengheinuo No.1 were done at Zhengzhou city in 2006.Comparison analysis by output of fresh ear,the trait of fresh ear,benefits of planting were conducted.The result showed that if the planting object was harvesting fresh ear,the optimally treatment combination of manure-density was planting density should 60 000 plants/hm^2 and the rate of fertilizer application should urea 450 kg/hm^2,acid phosphate 450 kg/hm^2,potassium chloride 240 kg/hm^2.The result gave some scientic basis for the popularizing of this variety.
