摘  要:
采用田间试验,研究了鼠茅草生草覆盖处理、大豆秸秆覆盖处理和花生秸秆覆盖处理的养分释放规律。结果表明,鼠茅草、大豆、花生秸秆的腐解大致可分为两个时期,养分快速释放期和缓慢释放期。腐解前20d为快速释放期,20d后为缓慢释放期。大豆、花生秸秆腐解的养分释放率均表现为K>P>C>N,鼠茅草腐解养分释放率表现为K>P>N>C。

摘  要:
Field experiments were carried out to study the nutrient releasing law intreatments covered by Vulpia myuros C. Gmelin,soybean stubble and peanut straw,respectively. The results showed that their decomposing process could be divided into two periods of rapid release and slow release period,and 20 days before decomposing for quick release period,and after that for slow release period. The nutrient releasing law of soybean stubble and peanut straw appeared K > P > C > N,but that of Vulpia myuros C. Gmelin was K > P > N > C.
