氮肥两种分次施用比例的效应（R1：6月13日施氮肥总量的一半，7月1日施氮肥总量的一半; R2：6月15日和7月1日各施两次等量氮肥，占总量的70%，8月1日施其余氮肥）和3个氮肥施用量研究了75、150和225 kg/ha对甜菜叶绿素含量、光合特性和根产量的影响。结果表明，与R1处理相比，施氮量为150和225 kg ha-1时，R2处理显著降低了光补偿点，但提高了光饱和点和实际光化学效率。与其他处理相比，氮肥施用量为150 kg ha-1的R2处理显著增加了5-29%的产糖量。
Effects of two split application ratios of nitrogen fertilizer (R1: half of the total nitrogen fertilizer was applied on 13 June, and the rest was applied on 1 July; R2: two equal amounts of N fertilizer accounting for 70% of total were applied on 15 June and 1 July, respectively, and the rest was applied on 1 August) and three N fertilizer application rates (75, 150, and 225 kg ha-1) on chlorophyll content, photosynthetic characteristics, and root yield of sugar beets were studied. The results showed that with N fertilizer application rates of 150 and 225 kg ha-1, R2 treatment significantly decreased light-compensation point, but increased light-saturation point and actual photochemical efficiency at the storage root development compared to R1 treatment. The R2 treatment with the N fertilizer application rate of 150 kg ha-1 significantly increased sugar yield by 5-29% compared to other treatments.
