磷细菌肥料是一种微生物制剂,借助于微生物的生命活动,可将土壤中不易被植物吸收利用的磷转变成易被植物吸收利用的磷,改善植物的磷素营养状况,促进植物体内的新陈代谢作用,提高产量,改进品质,并能缩短植物的生长发育周期,提早成熟。目前,磷细菌肥料的生产(工业生产或土法生产),多采用三级液体培养方法,即斜面菌种→液体种子(或固体种子)→液体培养。培养的菌液再用吸附剂如草炭土、炉灰、肥土、有机肥料等吸附。
Phosphorus Bacterial Fertilizer is a kind of microbial agent. With the help of life activity of microorganisms, phosphorus in the soil that can not be easily absorbed by plants can be transformed into phosphorus that is easily absorbed and utilized by plants. Phosphorus can improve plant nutrition status and promote metabolism in plants Role, improve yield, improve quality, and can shorten the plant growth and development cycle, early maturity. At present, the production of phosphorus bacteria and fertilizers (industrial production or indigenous production), the use of three liquid culture methods, namely bevel bacteria → liquid seed (or solid seed) → liquid culture. Cultivation of bacteria and then adsorbent such as peat soil, ash, fat soil, organic fertilizer adsorption.
