利用埋袋法模拟研究了二月兰、毛苕子两种绿肥的腐解及养分释放特征。结果表明,两种绿肥均在翻压后14 d 内腐解较快,随后腐解速率变慢,翻压80 d 时,二月兰、毛苕子的累积腐解率分别为66.92%和63.12%。两种绿肥不同养分的释放快慢不同,氮和钾在翻压7 d 内快速释放,磷在翻压80 d 内均稳步释放,养分累积释放率表现为钾>氮>磷。两种绿肥比较,二月兰的磷累积释放率显著高于毛苕子,其他养分的累积释放率也以二月兰较高。
利用埋袋法模擬研究瞭二月蘭、毛苕子兩種綠肥的腐解及養分釋放特徵。結果錶明,兩種綠肥均在翻壓後14 d 內腐解較快,隨後腐解速率變慢,翻壓80 d 時,二月蘭、毛苕子的纍積腐解率分彆為66.92%和63.12%。兩種綠肥不同養分的釋放快慢不同,氮和鉀在翻壓7 d 內快速釋放,燐在翻壓80 d 內均穩步釋放,養分纍積釋放率錶現為鉀>氮>燐。兩種綠肥比較,二月蘭的燐纍積釋放率顯著高于毛苕子,其他養分的纍積釋放率也以二月蘭較高。

The decomposition and nutrient release characteristics of two kinds of green manure crops, Orychophragmus violaceus and Vicia villosa L.,were studied by the nylon mesh bag method.The results showed that both the two green manure crops decomposed fast in the first 14 days after incubation,and then decomposed slowly.After 80 days of incubation,the accumulated decomposition rate of Orychophragmus viola-ceus and Vicia villosa L.were 66.92% and 63.12% respectively.The releasing rates of different nutrients in them were varied.Nitrogen (N)and potassium (K)were released rapidly in the initial 7 days,and phosphor-us (P)was released steadily in 80 days after incubation.The nutrient release rate was K >N >P.Orycho-phragmus violaceus had higher nutrients release rates compared with Vicia villosa L.,and had significantly higher phosphorus(P)release rate,specifically.
