摘要
为探究复合微生物菌剂对华麦1028生长发育及产量结构的影响,通过田间试验,设置4种处理,探究不施加肥料仅单独使用复合微生物菌剂以及在常规施肥的基础上使用复合微生物菌剂,对华麦1028生育期、株高、越冬苗、高峰苗、成穗率、有效穗数、穗长、穗粒数、千粒质量等田间表型及产量结构的影响。结果表明:处理2产量较CK增加5.3%,处理3较处理4增产15.1%。同时,越冬苗、高峰苗、成穗率及有效穗数、穗粒数较对照显著增加;不施加常规肥料仅添加复合微生物菌剂,小麦生育期较CK晚1 d;正常施肥的情况下添加生物菌剂使生育期提前1 d。可见复合微生物菌剂能够提高小麦的产量结构、提升化肥的利用率并调节小麦生育期。
In order to explore the effect of compound microbial agents on growth and yield structure of Huamai 1028.In this paper,through field experiment,four treatments were set up to explore the effects of only the compound microbial agents alone and compound microbial agents on the basis of conventional fertilization on growth period,plant height,overwintering seedlings,peak seedlings,spike formation rate,effective spike number,spike length,grain number per spike,thousand-grain weight and other field phenotypes and yield structure of Huamai 1028.The results showed that the yield of treatment 2 increased by 5.3%compared with CK,and the yield of treatment 3 increased by 15.1%compared with treatment 4.At the same time,overwintering seedlings,peak seedlings,spike formation rate,effective spike number,grain number per spike were significantly increased compared with the control.Under the treatment of no the application of conventional fertilizer and only the addition of compound microbial agents,the growth period of wheat was one day later than that of CK.Under the condition of normal fertilization,the growth period of adding biological agent was one day earlier.It can be seen that the compound microbial agent can improve the yield structure of wheat,increase the utilization rate of chemical fertilizer,and regulate the growth period.
