摘要: 复合微生物肥料既含速效氮、磷、钾,又含微生物和有机质,有望在碱土种植作物上发挥特殊作用,文章探讨了其对碱土种植玉米的增产效应。结果表明:施1 500 kg/hm2复合微生物肥料比习惯施肥显著提高了出苗率、株数和穗粒重,特别是对籽粒产量和地上部生物量的提高幅度达67.37%,29.66%;与不施肥相比,对籽粒产量和地上部生物量的提高幅度分别达201.36%,136.48%。施1 125 kg/hm2复合微生物肥料比习惯施肥显著提高了出苗率、苗高、株数和株高,但对籽粒产量和地上部生物量没有增产效应;与不施肥相比,对籽粒产量和地上部生物量的提高幅度分别达115.52%,83.02%。综上所述,施1 500 kg/hm2复合微生物肥料的增产作用明显好于当地习惯施肥。

Abstract: The compound microbial fertilizer contains fast-acting NPK,microbes and organic matter,and it is expected to play a special role in alkaline soil planting of many crops.This article discusses the effect on the yield increase through alkaline soil planting of corn.The application of 1 500 kg/hm2 compound microbial fertilizer significantly increased the emergence rate,the number of plants and the grain weight per spike compared with customary fertilization;especially notable was the increase of grain yield and aboveground biomass,which reached 67.37% and 29.66%.Compared with the control,the increase in grain yield and aboveground biomass reached 201.36% and 136.48% ,respectively.The application of 1 125 kg/hm2 compound microbial fertilizer significantly increased the seedling emergence rate,seedling height,plant number,plant height and stem diameter,but had no effect on either grain yield or aboveground biomass.Compared with the control,grain yield and the increase in aboveground biomass reached 115.52% and 83.02%,respectively.In this experiment,the stimulatory effect of applying 1 500 kg/hm2 compound microbial fertilizer was significantly better than that of local customary fertilization.
