摘 要：
通过复垦区大田试验,研究了煤基复混肥对土壤养分、酶活性及玉米产量的影响,目的是为了探究煤基复混肥培肥复垦土壤的最佳施用量。结果表明,煤基复混肥施用量为中肥时,土壤有机质含量在玉米拔节期、灌浆期和成熟期分别比施用量为高肥和低肥时提高了12.83%~48.72%,10.42%~15.80%,13.95%~32.08%;土壤碱解氮含量在玉米拔节期、灌浆期和成熟期分别比施用量为高肥和低肥时提高了42.86%~150.00%,58.36%~216.71%,38.43%~100.00%;土壤有效磷含量在玉米拔节期、灌浆期和成熟期分别比施用量为高肥和低肥时提高了7.47%~309.35%,5.19%~225.13%,1.68%~292.21%;土壤速效钾含量在玉米拔节期和灌浆期分别比施用量为高肥和低肥时提高了74.84%~239.30%,149.65%~383.09%;在玉米拔节期,土壤脲酶活性比施用量为高肥和低肥时提高了49.20%~398.61%,玉米产量比施用量为高肥和低肥时提高了6.96%~218.90%。施用量为中肥时煤基复混肥对复垦土壤肥力提升效果最好。

摘 要：
To explore the best application of coal-derived compound fertilize fostering fertility in reclaimed soil,the effects of coal-derived compound fertilize on soil nutrients,enzyme activities and corn yield were studied,based on field experiment in reclamation area.The results showed that the coal-derived compound fertilize was middle fertilizer,soil organic matter content in shooting period,pustulation period and mature period were compared for high and low dosage of fertilizer increased by 12.83%-48.72%,10.42%-15.80% and 13.95%-32.08%,respectively.The content of soil available nitrogen in shooting period,pustulation period and mature period were compared for the amount of high fertility and low fertility increased by 42.86%-150%,58.36%-216.71%,38.43%-100%,respectively.The soil available phosphorus content in shooting period,pustulation period and mature period were compared for high and low dosage of fertilizer increased by 7.47%-309.35%,5.19%-225.13% and 1.68%-292.21%,respectively.The content of available potassium in soil of high fertility and low fertilizer for corn in jointing and filling stage respectively than the amount increased by 74.84%-239.30%,149.65%-383.09%,respectively.Soil urease activity increased by 49.20%-398.61% at the jointing stage of corn.The yield of corn increased by 6.96%-218.90% when compared with the application of high fertilizer and low fertilizer.When the application amount is middle fertilizer,the coal-derived compound fertilize has the best effect on the soil fertility improvement.
