摘要: 以超级杂交稻“Y两优1号”为供试材料,保持总施氮量不变(180 kg·hm-2)条件下,研究不同比例有机无机肥配施对超级杂交稻产量构成及植株重金属含量的影响。结果表明,由施肥量-产量模型进行模拟,得到有机肥与尿素的施入量分别为606.75和288.18 kg·hm-2时,水稻产量最高(10084.37 kg·hm-2);有机肥与尿素施用量分别为202.32和353.17 kg·hm-2时,经济效益最佳(产量为9968.42 kg·hm-2)。不同比例有机无机肥配施对植株镉含量无显著影响。在6个梯度处理中,有机肥和尿素施肥量分别为600和289.27 kg·hm-2处理产量最高,且植株铬含量最低。

Abstract: Super hybrid rice “Y Liangyou No.1” was employed in a field experiment to investigate effects of combined application of organic and inorganic fertilizers (180 kg·hm-2)on yield composition and heavy metal content of the crop.Results show that based on the simulation using a fertilization rate-yield model,yield of the crop was the highest,reaching 10084.37 kg·hm-2,when 606.75 kg·hm-2 organic fertilizer and 288.18 kg·hm-2 urea were applied together,and the crop could yield an optimal economic benefit(grain yield:9968.42 kg·hm-2)when 202.32 kg·hm-2 organic fertilizer and 353.17 kg·hm-2 urea were applied together.No significant difference was observed in Cd content of the plant between treatments different in ratio of the organic and inorganic fertilizer combination.However,among the six treatments,the one(600 kg·hm-2 organic fertilizer and 289.27 kg·hm-2 urea)was the highest in crop yield and the lowest in plant Cr content.
