- 摘要:
- 为减少氮肥施用量,明确玉米施用聚脲甲醛缓释肥的最佳施肥配方。本研究以鑫鑫1号为材料,以聚脲甲醛的氮利用率相当于普通尿素的1.3、1.6、1.9倍,设置常规施肥、不施氮肥和几种不同聚脲甲醛施用量处理,研究聚脲甲醛对玉米产量、氮肥利用率及土壤氮素含量的影响。结果表明:MU50、MU70对玉米土壤全氮、碱解氮含量无显著影响。处理2(1.3倍利用率75%MU50+25%PU)、处理3(1.3倍利用率50%MU50+50%PU)的氮肥利用率高于常规施肥,其他各处理氮肥利用率均不同程度低于常规施肥。相同施肥量情况下,施用MU50氮肥利用率高于MU70。减施氮肥较常规施肥降低穗粗、百粒重,增加秃尖长度,产量降低,其中处理2、处理12(1.3倍利用率75%MU70+25%PU)与常规施肥产量差异不显著。相同施肥量情况下,施用MU50产量高于MU70。综上,处理2(1.3倍利用率75%MU50+25%PU)在保证产量不降低的同时,氮肥利用率较高,具有节肥增效的潜力。
- Abstract:
- In order to reduce the amount of nitrogen fertilizer,to define the optimum formula of slow-release polyurea formaldehyde fertilizer for maize.Xinxin No.1 was used as material.The nitrogen utilization rate of polyurea-based formaldehyde was 1.3,1.6 and 1.9 times that of common urea.The effects of conventional fertilization,no nitrogen fertilization and several different application rates of polyurea-based formaldehyde on maize yield,nitrogen use efficiency and soil nitrogen content were studied.The results showed that MU50 and MU70 had no significant effect on the content of total nitrogen and alkali-hydrolyzed nitrogen in Maize soil.Nitrogen use efficiency of treatment 2 (1.3 times utilization rate 75% MU50+25% PU)and treatment 3 (1.3 times utilization rate 50% MU50+50% PU) was higher than conventional fertilization,and nitrogen use efficiency of other treatments was lower than conventional fertilization in varying degrees.Under the same amount of fertilizer,the nitrogen use efficiency of MU50 was higher than MU70.Compared with conventional fertilization,reduced nitrogen fertilizer reduced ear diameter,100-grain weight,increased bald tip length,and reduced yield.There was no significant difference between treatment 2,treatment 12(1.3 times utilization rate 75% MU50+25% PU) and conventional fertilization.Under the same amount of fertilizer,the yield of MU50 was higher than MU70.In conclusion,Nitrogen fertilizer utilization efficiency of treatment 2 (1.3 times utilization rate 75% MU50+25% PU) was higher while ensuring yield.treatment 2 had the potential of saving fertilizer and increasing efficiency.
