生物菌肥对辣椒和土壤肥力影响初探

为了探索生物菌肥的效应和合理施用,在保护地施用生物菌肥后栽植辣椒,分析测定施用纯化肥、未发酵型生物菌肥和发酵型生物菌肥下的辣椒产量、经济效益、品质和土壤养分含量。结果表明,在增产增收效果方面,发酵型生物菌肥明显优于未发酵型生物菌肥。生物菌肥还对抑制辣椒亚硝酸盐积累、提升辣椒Vc含量、调节土壤pH值、增加土壤放线菌数量、提高土壤速效磷含量有一定作用。发酵型生物菌肥能提升土壤速效钾、碱解氮含量。

Effects of Bacterial Manure on Capsicum and Soil Fertility

In order to research effects of bacterial manure and guide reasonable application, the yield, economic benefit, quality of capsicum and content of soil nutrient in protected field applied with fertilizer, unfermented and fermented bacterial manure were measured. Results showed that fermented bacterial manure was better than unfermented bacterial manure on increasing production and benefit. Bacterial manure restrained nitrite accumulation, increased Vc content of capsicum and soil pH, raised soil actinomycetes number and soil available phosphorus. Fermented bacterial manure increased the contents of available potassium and alkali-hydrolyzable nitrogen.
