农家肥对改良土壤结构,培肥地力,全面供给作物养分,提高土壤生物活性,提高土壤养分有效性,维持农业生态系统良性循环和实现农业可持续发展具有化学肥料不可替代的作用。但发酵的农家肥,因存放时间长,发酵温度底,施入烟田时农家肥中含有较多未腐熟的秸秆、病毒、病菌和杂草种子等因素,施入烟田后,造成烟叶不能适时落黄,影响烤烟质量。使用促腐剂可有效解决此问题,但不同厂家生产的腐熟菌剂使用效果不一样,基于此,针对这个问题展开讨论。
Manure fertilizer has an irreplaceable role of chemical fertilizers in improving soil structure, fertilizing fertility, supplying crop nutrients in an all-round way, improving soil biological activity, improving soil nutrient availability, maintaining a virtuous circle of agro-ecosystems and achieving sustainable agricultural development. However, the fermentation of manure, due to the long storage time, the fermentation temperature at the end, when applied to tobacco fields farmer fat contains more non-decomposed straw, viruses, germs and weed seeds and other factors, into tobacco fields, resulting in tobacco can not Timely yellow, affecting the quality of flue-cured tobacco. The use of preservatives can effectively solve this problem, but different manufacturers use the effect of rotting agents is not the same, based on this, in order to discuss this issue.
