Study On Composting The Seeds And Leaves Of Camptotheca Acuminata Decaisne After The Cpt Extracted

ABSTRACTBy separating4 screening and mixed-culturing the microbes which are from seeds and leaves of Cwnptotheca acwninata Decaisne~ 40 high-effective microorganisms are gotten. Among of them there are 16 bacterium, 7 actinomyces and 17 fungi. Through the screening experiment, excellent mixed-ratio of fermentation substrate is gotten. That is following: waste solidof Camptotheca acwninata Decaisne(secds58. 5%+leavcs 19. 5%+bran22%), saccharose 1%, CaSO41%, carbainide 0. 5%~. According to the mixed-ratio of fermentation substrate and 40 high-effective micoorganisms, To compost the waste material into humus which can be utilized by plant And through the composting, fermentation and management process are searched. Rotted degree indexes of Xishu compost are fixed. The following are laboratory results:The spone douph parameters of Camptotheca aczontnata Decaisne compost are following: water content are 60 percent, ratio of element C and clement N is from 29 to 33, highest temperature retain from 50C to 601~, periodic time are from 7 to 14 days. Sccondaiy fermentation parameters are following: water content are below 60 percent, ratio of element C and element N is from 29 to 33, highest temperature is below 45C, periodic time are from 7 to 30 days.Rotted compost of Camptotheca acuminata Decaisne has much humic acid and microelement. Contents of C, N, P and K element in rotted compost of that are higher 4 times than those of livestock feces. PH of Camptotheca acwninata Decaisne rotted compost is from 6.8 to 7.5, ratio of element C and element N is 17.6, ratio of element C and organicNin water extract is 6.89.
