摘  要：
文章对不同种植年限的蔬菜保护地0~60 cm土层土壤有机质各组分进行研究,对比分析黑土型保护地有机质含量、活性有机质、缓性有机质和惰性有机质含量。结果表明,哈尔滨市蔬菜保护地土壤有机质总体上处于不稳定状态,其中活性有机质、惰性有机质和缓性有机质在0~20 cm土层积累较多,随土层深度的增加各形态有机质的含量逐渐降低;在各个层次土壤中各形态有机质随着种植年限增加呈现阶段性变化,在一时间段内受施肥种类、用量、种植方式的影响表现出随着年份增加而先增加后减少趋势,一定年限后有机质含量有减少趋势,种植多年后含量会低于大田土壤;蔬菜保护地土壤有机质的积累以缓性有机质的含量最多,其次为惰性有机质,活性有机质最少,其中活性有机质与有机质的变化趋势基本一致。

摘  要：
In this paper, different vegetables planted years 0-60 cm soil protected the various components of soil organic matter has been studied, Comparative analysis of black- type protection to the organic matter content, active organic matter, slow and inert organic matter content of organic matter, The results showed that:Harbin vegetables to protect soil organic matter in general increasing trend in an unstable state, One active organic matter, organic matter inert organic gentle nature of the accumulation of soil in 0-20 cm more, Increased with soil depth and the form of organic matter decreased gradually; At all levels of soil organic matter in the form of plant life increases with the stage show changes,Fertilization in a period of time by type, dosage, method of planting is shown to increase with the years the trend was first increased and then decreased, Organic matter content after a certain number of years a decreasing trend, after years of planting the soil level is lower than the field; Protected vegetables to slow the accumulation of soil organic matter content of organic matter most, Followed by inert organic matter, reactive organic matter at least, one active organic matter and organic matter are basically the same trends.
