【摘要】：QE制劑是一種含有微生物和礦物質(zhì)的新型復(fù)合材料。為研究該材料對畜禽糞便高溫堆肥進(jìn)程及品質(zhì)的影響,設(shè)置無添加劑(CK)、添加常規(guī)微生物菌劑(BJ)、添加QE制劑(QE)共3組處理,并以豬糞為原料,立式密閉發(fā)酵塔(容量50t)為反應(yīng)裝置,進(jìn)行了為期7d的堆肥實(shí)驗(yàn)。結(jié)果表明:QE組堆溫于第3天達(dá)到最大值72.7℃,比CK、BJ組分別提前2d、5d,且55℃以上持續(xù)天數(shù)為4d,高于其它兩組處理。QE制劑可以有效提高堆肥的養(yǎng)分含量,堆肥7d后總氮、總磷、總鉀含量分別達(dá)到2.62%、3.04%、2.29%,比BJ組高16.25%、2.36%、4.09%,比CK組高29.00%、14.72%、16.84%。同時,添加QE制劑的堆肥品質(zhì)符合國家《有機(jī)肥料》(NY525-2012)標(biāo)準(zhǔn),且優(yōu)于其它兩組處理。此外,QE、BJ組堆肥7d的種子發(fā)芽率指數(shù)分別為93.33%、90.00%,堆體已完全腐熟,而CK組為31.67%,未腐熟。研究表明,QE制劑在畜禽糞便高溫堆肥過程中具有促進(jìn)升溫、加強(qiáng)保溫、減少氮素?fù)p失、提高養(yǎng)分含量、改善堆肥品質(zhì)的作用。
[Abstract]:QE preparation is a new type of composite material containing microorganisms and minerals. In order to study the effect of the material on the process and quality of high temperature composting of livestock and poultry manure, it is set up without additive (CK), adding conventional microbial inoculant (BJ), adding QE preparation (QE), and using pig manure as raw material and vertical closed fermentation tower (capacity 50t) as a reaction device. The results of the 7d composting experiment showed that the maximum temperature of the QE group reached 72.7 degrees centigrade at third days, 2D and 5D ahead of CK and BJ, and the number of continuous days above 55 centigrade was 4D, higher than the other two groups of.QE preparation, which could effectively improve the nutrient content of the compost, and the total nitrogen, total phosphorus and total potassium content reached 2.62%, 3.04%, 2.29%, respectively, and 16. higher than the BJ group after 7d. 25%, 2.36%, 4.09%, 29%, 14.72%, and 16.84%. higher than the CK group, and the compost quality of adding QE conformed to the national standard of organic fertilizer > (NY525-2012), and was better than the other two groups. In addition, the seed germination index of QE and BJ group 7d was 93.33%, 90%, and the CK group was 31.67%, and not decayed. The study showed QE preparation. In the process of high temperature composting of livestock manure, it has the functions of promoting temperature rise, strengthening heat preservation, reducing nitrogen loss, raising nutrient content and improving compost quality.
