基肥种类与施肥方式对冬小麦生长发育及产量的影响

Effects of basal fertilizer types and fertilization methods on the growth and yield of winter wheat

  • 摘要: 【目的】 研究不同基肥及施肥方式对冬小麦生长发育和产量的影响,为新疆冬小麦基肥合理施用提供理论。 【方法】 2019~2020年度,在大田条件下,以新冬60号为材料,采用双因素裂区试验设计,设置2种施肥方式:种肥分离(S1)、种肥同播(S2)和2种基肥种类:磷酸二铵(F1)、美可辛(F2)共计4个处理,研究不同处理对冬小麦植株性状、叶片SPAD值、LAI、干物质积累及产量和产量构成的影响。 【结果】 美可辛种肥分离处理(F2S1)相较于其它处理,冬小麦株高、SPAD值、叶面积指数(LAI)、干物质积累及有效穗数和籽粒产量和生物量均表现较好;与磷酸二铵种肥同播(F1S2)相比,美可辛种肥同播(F2S2)下冬小麦的株高表现为降低、茎粗表现为增加、穗长表现为增长,且有效穗数、籽粒产量、生物量均表现较高。 【结论】 美可辛采用种肥同播方式有利于促进冬小麦增产。

     

    Abstract: 【Objective】 The purpose of this study is to explore the effects of different basal fertilizers and fertilization methods on the growth and yield of winter wheat in southern Xinjiang. 【Methods】 A two-factor split zone experiment design was adopted in the field of Xindong 60 from 2019 to 2020.Two fertilization methods were set: basal application (S1), seed application (S2) and two basal fertilizer types: diammonium phosphate (F1) and methoxin (F2).The effects of different treatments on plant traits, chlorophyll content (SPAD value), leaf area index (LAI), dry matter accumulation and yield of winter wheat were studied. 【Results】 The results showed that compared with other treatments, plant height, SPAD value, leaf area index (LAI), dry matter accumulation, effective panicle number, grain yield and biomass of winter wheat were all better under F2S1 treatment.Compared with diammonium phosphate seed fertilizer (F1S2), plant height decreased, stem diameter increased, panicle length increased, and effective panicle number, grain yield and biomass of winter wheat were higher under mekoxin seed fertilizer (F2S2). 【Conclusion】 It can be seen that methoxin is a kind of fertilizer that can promote high yield of wheat.If winter wheat is planted with seed and fertilizer, methoxin can be used as a reference for production.
