【摘要】：試驗(yàn)研究了長(zhǎng)期不同施肥下剖面(0~100 cm)土壤有機(jī)碳、全氮、硝態(tài)氮、微生物碳氮以及土壤pH的空間變化。結(jié)果表明:與單施化肥相比,長(zhǎng)期有機(jī)肥和化肥配施顯著提高了0~20 cm表層土壤有機(jī)碳、全氮、硝態(tài)氮和微生物碳氮含量,并且土壤有機(jī)碳和微生物碳氮的增加主要集中在0~40 cm土層。在0~20 cm和20~40 cm土層,等氮量有機(jī)無機(jī)肥配施(M1NPK和SNPK)處理土壤有機(jī)碳含量顯著高于化肥NPK處理(P0.05),同時(shí)二處理土壤全氮含量沒有由于化肥氮施用量減少而下降。與不施肥ck相比,單施化肥顯著降低了土壤微生物量碳氮含量。在40 cm土層以下,與NPK處理相比,M2NPK、NP和N處理硝態(tài)氮累積量明顯增加,而M1NPK和SNPK處理硝態(tài)氮累積量明顯減少。長(zhǎng)期不同施肥對(duì)土壤酸化的影響主要集中在0~40 cm土層,單施化肥處理土壤pH顯著低于不施肥(ck)和有機(jī)無機(jī)肥配施處理(P0.05),其中2012年秸稈還田(SNPK)處理0~20 cm土壤pH比NPK處理高2.17。表明有機(jī)無機(jī)肥配施不僅能提高和維持土壤碳氮水平,還能防止土壤酸化的發(fā)生,尤其施用有機(jī)肥氮替代部分化肥氮的有機(jī)無機(jī)肥配施模式是東北黑土區(qū)最有效的施肥措施之一。
[Abstract]:The spatial changes of soil organic carbon, total nitrogen, nitrate nitrogen, microbial carbon and nitrogen and soil pH were studied in the long term different fertilization (0~100 cm) profiles. The results showed that compared with the single fertilizer, the long-term organic fertilizer and fertilizer application significantly improved the soil organic carbon, total nitrogen, nitrate nitrogen and microbial carbon and nitrogen content in the surface soil of 0~20 cm, and the soil organic matter. The increase of carbon and microbial carbon and nitrogen was mainly concentrated in the 0~40 cm soil layer. In 0~20 cm and 20~40 cm soil layer, the content of soil organic carbon with equal nitrogen content organic and inorganic fertilizer (M1NPK and SNPK) was significantly higher than that of the fertilizer NPK treatment (P0.05), while the total nitrogen content in the two soil treatment was not reduced by the reduced fertilizer nitrogen application. Compared with the non fertilization CK, Dan Shi The soil microbial biomass carbon and nitrogen content was significantly reduced. Under the 40 cm soil layer, the accumulation of nitrate nitrogen in the treatment of M2NPK, NP and N increased significantly compared with the NPK treatment. The accumulation of nitrate nitrogen in the treatment of M1NPK and SNPK was significantly reduced. The effect of long-term fertilization on Soil acidification was mainly concentrated in the cm soil layer of 0~40, and the pH of the soil treated by a single fertilizer application was significantly lower. In the treatment of CK and organic and inorganic fertilizer (P0.05), in 2012 straw returning (SNPK) treatment of 0~20 cm soil pH higher than NPK processing high 2.17. showed that organic and inorganic fertilizer can not only improve and maintain soil carbon and nitrogen levels, but also prevent soil acidification, especially organic manure nitrogen instead of partial fertilizer nitrogen organic manure application The pattern is one of the most effective fertilization measures in the black soil region of Northeast China.
