摘要: 为探究控释肥施用量对鲜食玉米(Zea mays L.)生长状况的影响,以仲甜5号和西星五彩鲜糯为材料,开展不同肥力的田间小区试验,比较不同生育时期玉米的生长指标,并筛选最佳的控释肥施用量。结果表明,控释肥施用量与鲜食玉米除糖度外的各指标的拟合模型决定系数均在0.8以上,均达极显著水平(P<0.01),说明施用控释肥能显著增加鲜食玉米各生长指标。600 kg/hm2为本试验条件下的最佳控释肥施用量;当过量施肥时,大部分指标呈下降趋势,肥料利用率降低。

Abstract: In order to explore the effect of controlled-release fertilizer application rate on the growth status of fresh corn(Zea mays L.), field plot experiments with different fertility were carried out with ‘Zhongtian No.5’ and ‘Xixing Wucai Xiannuo’ as materials, the growth indexes of maize in different growth periods were compared, and the best controlled-release fertilizer application rate was screened. The results showed that, the determination coefficient of the fitting model between the application amount of controlled-release fertilizer and each index of fresh corn except sugar content was above 0.8, which reached a very significant level (P<0.01), indicating that the application of controlled-release fertilizer could significantly increase the physiological indexes of fresh corn. The 600 kg/hm2 application rate was the best fertilization amount of controlled-release fertilizer under this experimental condition. When excessive fertilization occurred, most indexes showed a downward trend, and the fertilizer utilization rate decreased.

Key words: controlled-release fertilizer, fresh corn(Zea mays L.), agronomic trait, effect
