喷施复合微生物肥料对小青菜生产的影响

目的]研究复合微生物肥料对小青菜的增产效果,为减少化肥施用提供依据。方法]以小青菜绿秀91-1为试验材料,采用田间试验分析复合微生物肥料a、复合微生物肥料a灭活基质对小青菜株高、产量的影响。结果]增施微生物肥料对小青菜株高的改善效果并不明显;增施微生物肥料能极显著增加小青菜产量,比对照处理增产74.6%~133.0%,且比灭活处理增产66.8%,微生物肥料处理比灭活处理对小青菜具有更好的增产效果。结论]微生物肥料对小青菜的增产效果明显,可在生产中推广应用。

Effect of Compound Microbial Fertilizer on the Production of Brassica chinensis

Objective]The yield-increasing effect of applying compound microbial fertilizer on Brassica chinensis was studied to provide evidence for reducing fertilizer application rate.Method]Taking Lüxiu 91-1 as test material, field experiment was carried out to analyze effect of compound microbial fertilizer a and inactivation matrix of compound microbial fertilizer a on plant height and yield of Brassica chinensis.Result] The results showed that increasing application of microbial fertilizer couldn't improve Brassica chinensis's plant height obviously;increasing application of microbial fertilizer could significantly increase the yield of Brassica chinensis, compared with the control treatment, yield increased by 74.6%-133.0%, and than inactivation treatment increased by 66.8%, microbial fertilizer had better effect of yield increasing than inactivation for Brassica chinensis.Conclusion]Yield-increasing effect of microbial fertilizer was significant.It could be applied in producing.
