摘要
为明确不同类型脲醛缓释肥料在小麦上的应用效果,加快该类肥料的推广应用,选取4种不同脲醛缓释肥料作底肥,测定对比不同脲醛缓释肥料对济麦44不同生育期生长发育指标和产量的影响。结果表明,施用添加了黄腐酸和有益微生物菌群的脲醛缓释复合肥料24-16-6[w(N)≥24%,w(P2O5)≥16%,w(K_(2)O)≥6%],小麦灌浆期旗叶叶面积、叶绿素含量、千粒质量和产量均较高,产量达到8904.6 kg/hm^(2);施用普通脲醛复合肥料25-14-6[w(N)≥25%,w(P_(2)O_(5))≥14%,w(K2O)≥6%],小麦拔节后单株分蘖数、单株干物质质量和株高较高,产量为8858.6 kg/hm^(2);添加了黄腐酸和海藻酸的脲醛复合肥料24-16-6[w(N)≥24%,w(P_(2)O_(5))≥16%,w(K_(2)O)≥6%],越冬期小麦单株分蘖数、次生根条数、单株干物质质量均较高,但后期生长减缓,产量为8739.3 kg/hm^(2);施用掺混肥料18-20-5[w(N)≥18%,w(P_(2)O_(5))≥20%,w(K_(2)O)≥5%]的小麦不同生育期生长发育指标和产量均最低,产量为8418.9 kg/hm^(2)。因此,脲醛缓释肥料添加部分黄腐酸和有益活菌,对小麦施用效果较好。
In order to explore the application effect of different types of urea-formaldehyde slow-release fertilizers on wheat and accelerate the application and promotion,four different urea-formaldehyde fertilizers were selected as base fertilizers to compare the effects on the growth and yield of‘Jimai 44’.The results showed that under the application of urea-formaldehyde compound fertilizer(24-16-6)[w(N)≥24%,w(P_(2)O_(5))≥16%and w(K_(2)O)≥6%]with fulvic acid and beneficial living bacteria,the flag leaf area,chlorophyll content,1000-grain weight and yield of wheat at filling stage were higher,and the yield was 8904.6 kg/hm^(2).Under the application of common urea-formaldehyde compound fertilizer(25-14-6)[w(N)≥25%,w(P_(2)O_(5))≥14%and w(K2O)≥6%],the tiller number per plant,dry matter weight per plant and plant height of wheat after jointing were higher,and the yield was 8858.6 kg/hm^(2).Under the application of urea-formaldehyde compound fertilizer 24-16-6 with fulvic acid and alginate,the number of tillers per plant,the number of secondary roots and the dry matter weight per plant of winter wheat were higher,but the growth slowed down in the later stage,and the yield was 8739.3 kg/hm^(2).Under the application of mixed fertilizers(18-20-5)[w(N)≥18%,w(P_(2)O_(5))≥20% and w(K_(2)O)≥5%],the growth and development indexes and yield of wheat at different growth stages were the lowest,and the yield was 8418.9 kg/hm^(2).In conclusion,the effect of urea-formaldehyde slow-release fertilizer added with fulvic acid and beneficial living bacteria on wheat is better.
