研究评价不同用量微生物菌剂与种肥配施对夏玉米根茎性状及产量的影响。结果表明,在试验条件下,种肥(15-15-15硫酸钾复合肥)15kg配施微生物菌剂7.5kg、5kg、2.5kg,产量较对照分别提高15.2%、14.5%和8.4%,玉米根茎性状与常规施肥差异均达到显著或极显著水平。综合成本因素考虑,在生产中以种肥(15-15-15硫酸钾复合肥)15kg配施微生物菌剂5kg、2.5kg为宜,节本增效作用明显。
The effects of different amount of microbial inoculants and fertilizer on rhizome traits and yield of summer maize were studied. The results showed that under the experimental conditions, 15kg of compound fertilizer (15-15-15 potassium sulfate compound fertilizer) was added with 7.5kg, 5kg and 2.5kg of microbial inoculant, the yield was 15.2%, 14.5% and 8.4% higher than the control respectively. The difference of rhizome characters and conventional fertilization reached significant or extremely significant level. Comprehensive cost considerations, in the production of fertilizer (15-15-15 potassium sulfate compound fertilizer) 15kg with microbial agents 5kg, 2.5kg is appropriate, the effect of this section synergy.
