植物源药肥对花生生长、害虫防效及土壤微生物活性的影响

试验以池栽方式,利用植物源实物及提取物与有机无机营养成分合理组配研制成的植物源药肥,以相同投入成本的有机无机肥与化学农药组配使用为对比,研究比较了各处理对花生生长、产质、防效和土壤微生物活性的作用。结果表明,与常规施肥用药相比,施用植物源药肥降低花生植株高度,显著增加茎粗、侧枝长度和果针数量,增强花生抗倒伏能力,增产9.4%～11.5%,产量差异达到0.01显著水平,害虫防治效果相当,不同程度的增加土壤细菌、真菌及放线菌数量,使用该肥料对土壤生态环境具有更高的安全性。

Effects of Plant-sourced Officinal-fertilizer on Earthnut Growth, Anti-pest Efficiency and Soil Microbial Activity

In order to study the effects of plant-sourced officinal-fertilizer on earthnut growth, anti-pest efficiency and soil microbial activity, a plant-sourced officinal-fertilizer, distilled matters from them, was used. The experiment results indicated that earthnut anti-pest efficiency was increased after the application of the plant-sourced officinal-fertilizer. Earthnut height was reduced, but caulis wideness, branch length and nut numbers were increased. The output of earthnut was increased by 9.4-11.5%. Soil bacteria, epiphyte and actionmyees numbers were increased in different degree after the application of the plant-sourced officinal-fertilizer. Soil environment Security were evaluated.
