【摘要】：【目的】為了解海南省商品有機(jī)肥質(zhì)量狀況,分析海南省商品有機(jī)肥的理化性質(zhì)以及元素組成�！痉椒ā繉⒉杉挠袡C(jī)肥樣品經(jīng)過預(yù)處理測定了有機(jī)肥的鮮樣含水量、有機(jī)質(zhì)含量、pH值、氮、磷以及鉀的含量。同時(shí)還測定了有機(jī)肥的灰分、腐殖酸含量以及中微量元素的含量�！窘Y(jié)果】商品有機(jī)肥的合格率為7.84%,按照有機(jī)肥原料來源將合格率從大到小排序:植物性有機(jī)肥(合格率=33.33%)海藻類有機(jī)肥(合格率=25.00%)不明來源商品有機(jī)肥(合格率=11.11%);魚蝦有機(jī)肥、羊糞有機(jī)肥、牛骨粉有機(jī)肥以及黃腐酸有機(jī)肥中沒有合格產(chǎn)品。有機(jī)肥理化性狀與營養(yǎng)元素含量的分布范圍較大,理化性質(zhì)中的鮮樣含水量、pH、有機(jī)質(zhì)含量、灰分以及腐殖酸含量的范圍分別為1.4%~67.9%、3.41~9.49、8.36%~83.01%、22.81%~85.67%、85.24~871.49 mg/kg;N、P_2O_5、K_2O、Ca、Mg、S、Fe以及Mn的含量的變化范圍分別是:0.24%~10.16%、0.21%~7.10%、0.19%~8.48%、0.02~3.37 g/kg、0.03~0.78 g/kg、0.60~2.48 g/kg、0.34~17.65 g/kg、0.01~0.27 g/kg。測定指標(biāo)中除鮮樣含水量和Ca含量之外,其余指標(biāo)的分布特征均符合正態(tài)分布�！窘Y(jié)論】海南省商品有機(jī)肥質(zhì)量狀況總體較差,不同有機(jī)肥之間營養(yǎng)元素以及理化性質(zhì)等指標(biāo)的差異較大。
[Abstract]:[objective] to understand the quality of commercial organic fertilizer in Hainan Province, analyze the physical and chemical properties and elemental composition of commercial organic fertilizer in Hainan Province. [methods] the fresh water content of organic fertilizer samples was determined by pretreatment. The content of organic matter is pH value, nitrogen, phosphorus and potassium content. At the same time, the ash content of organic fertilizer was also determined. [results] the qualified rate of commercial organic fertilizer was 7.84. According to the source of organic fertilizer, the qualified rate was ranked from large to small: vegetable organic fertilizer (qualified rate: 33.33%) Organic fertilizer of unknown origin (11.11%), organic fertilizer of fish and shrimp (11.11%), organic fertilizer of fish and shrimp (11.11%), organic fertilizer of fish and shrimp (11.11%), There are no qualified products in sheep manure, bovine bone powder and fulvic acid organic fertilizer. 鏈夋満鑲ョ悊鍖栨，
