摘  要：
为草甸白浆土水稻科学施氮提供可靠的技术支撑,在三江平原草甸白浆土上开展了氮肥用量研究的多点试验,根据施肥量—水稻产量对应关系提出草甸白浆土水稻优化施肥技术,并在大面积生产上进行验证。研究结果得出:草甸白浆土上水稻产量与施氮量呈2次曲线关系,随施氮量增加而提高,施氮量为101.50kg·hm~(-2),可得到最高理论产量为8 279.70 kg·hm~(-2);施氮量超过101.50 kg·hm~(-2)后产量则下降;施肥量为97.56 kg·hm~(-2),水稻理论产量7 909.43 kg·hm~(-2),水稻可取得最大的经济效益;水稻产量与氮素累积量呈2次函数关系,随施氮量增加,植株氮素含量增加,但氮素累积量降低,水稻产量降低与水稻生物产量降低有关。大面积示范证明,草甸白浆土氮素最佳推荐氮肥用量符合农业生产实际,施氮量为100 kg·hm~(-2)可以达到高产兼高效的生产目标。

摘  要：
In order to provide reliable technical support for the scientific application of nitrogen to rice in meadow albic soil,this paper carrys out a multi-point experiment on the study of the amount of nitrogen fertilizer on meadow albic soil in Sanjiang Plain,and put forward an optimized fertilization technology for rice in meadow albic soil according to the corresponding relationship between fertilizer amount and rice yield,and verify it in large-scale production.The results show that there is a quadratic curve relationship between rice yield and nitrogen application rate on meadow albic soil,which increases with the increase of nitrogen application rate.When the nitrogen application amount is 101.50 kg·hm~(-2),the maximum theoretical yield can be 8 279.70 kg·hm~(-2).The yield will decrease when the amount of nitrogen applied exceeds 101.50 kg·hm~(-2).When the amount of fertilizer applied is 97.56 kg·hm~(-2) and the theoretical yield of rice was 7 909.43 kg·hm~(-2),rice could obtain the greatest economic benefit.The yield of rice has a quadratic function relationship with the amount of nitrogen,and the nitrogen content of the plant increases with the increase of nitrogen application rate.However,the decrease of nitrogen quantity and rice yield is related to the decrease of rice biological yield.Large-scale demonstration shows that the best recommended nitrogen fertilizer amount for meadow albic soil is in line with the actual agricultural production,and the production target of high yield and high efficiency can be achieved when the nitrogen fertilizer amount is 100 kg·hm~(-2).
