| 摘 要： | 本研究的目的是为了取得有关施肥参数,建立吉林省开原地区超级稻施肥模型。应用"3414"设计方案对超级稻进行田间肥效试验,研究不同施肥配方对其产量的影响。结果表明,在一定范围内,氮肥对水稻生长有显著的影响,而磷、钾肥的影响较小。建议开原地区超级稻的氮、磷、钾施用量分别为N240.0kg/hm2、P2O5150.0kg/hm2、K2O150.0kg/hm2,并在做好配方施肥的同时,掌握好施肥时期和比例,氮肥要分期施入,保证超级稻各个生长期所需氮素。

| Abstract: | The purpose of this study are in order to obtain the relevant application parameters,and to set up the fertilization model of super high-yield rice in Kaiyuan prefecture.The "3414"design is used to do research yield impact of super high-yield rice under different fertilizer formula.The results show that,nitrogen fertilizer had the highest effect on rice growth when the N、P and K is at a certain level,compared to potassium and phosphorus fertilizers.The proposal of nitrogen,potassium and phosphorus are N 240.0kg/hm2,K2O 255.0 kg/hm2 and P2O5 90.0 kg/hm2.We should do different fertilizer formula well at the same time,should master the application period and the proportion of nitrogen fertilizer should be applied in phases to ensure that all super high-yield rice growing season nitrogen requirements. |
