连续施用不同量有机肥对土壤肥力及玉米产量的影响
Effects of Consecutive Application of Different Quantities of Manure on Soil Fertility and Maize Yield
摘要
Abstract
The different quantities of manure were applied to field in Changtu county of Liaoning province for consecutive six years. The effects of manure on soil nutrient contents,microbial quantities and maize yield were studied, so as to provide a scientific basis for improving farmland soil fertility and agricultural sustainable development. The results showed that compared with the control without manure,the contents of soil organic matter,total nitrogen,available nitrogen,available phosphorus and available potassium of the treatments with manure increased by 17. 4%—77. 4%, 10. 9%—55. 5%, 17. 8%—36. 4%, 503. 9%—1371. 8% and 29. 4%—203. 7%,respectively;moreover,the quantities of bacteria and acti-nomycete of the treatments with manure were enhanced by 7. 7—10. 7 times and 10. 6—9. 9 times the quantities of control. The orders of nutrients contents and microbial quantities in soils were 60000 kg/ha manure＞37500 kg/ha manure＞15000 kg/ha manure＞control. Compared with the control,the maize leaf spad,straw stiffness and root weight of the treatments with manure as well were improved;maize yield was increased by 23. 5%—33. 1%,and the treatment with 37500 kg/ha had the highest yield.关键词
