施用复合微生物菌剂对几种农作物产量品质及土壤养分状况影响的研究

通过在常规施肥和减量施肥基础上施用复合微生物菌剂，研究了其对花椰菜、茶叶、葡萄、翠冠梨4 种作物产量、产值、品质及土壤养分状况的影响。结果表明：在常规施肥基础施用复合微生物菌剂对4 种作物都有较好增产增收效果，其中花耶菜增产3704 kg/hm2，增幅16.6%；茶叶增产54 kg/hm2，增幅4.0%；葡萄增产1334 kg/hm2，增幅6.6%；翠冠梨增产1050 kg/hm2，增幅4.8%。这些作物对应的产值分别增收4089、8124、8535、5400 元/hm2。此外，试验结束后土壤有机质及碱解氮、有效磷、速效钾、pH值都有一定程度的提升。

Effect of Composite Microbial Agents on Crop Yield, Quality and Soil Nutrients

A field experiment was conducted to evaluate the effect of conventional and reduced fertilization with a composite microbial agent on soil nutrients, crop nutrient status, and yield. The crops included broccoli, tea, grape, and‘Cuiguan’pear. The results indicated that integrated use of conventional fertilization with the composite microbial agent significantly increased broccoli yield by 16.6% (3704 kg/hm2), tea yield by 4.0% (54 kg/hm2), grape yield by 6.6% (1334 kg/hm2) and pear yield by 4.8% (1050 kg/hm2), respectively compared with that of control. Meanwhile, the output value of the above crops increased by 4089, 8124, 8535 and 5400 yuan/hm2 correspondingly. Additionally, organic matter, available nitrogen, available phosphorus, available potassium and pH value in soil increased to some extent.
