甘蔗叶不同还田方式对土壤养分的影响
Effects of Different Returning Field Methods on Soil Nutrient of Sugarcane Leaf
摘要
Abstract
In order to make full use of the sugarcane leaf resources and mitigate environmental problems brought by the straw burning, effects of three different sugarcane leaf returning field methods on soil nutrient were dynamically monitored. The results showed that it was helpful for the slow releasing of organic carbon, nitrogen, phosphorus, potassium with the methods of sugarcane leaf crushing returning and deeply burning to field. The method of sugarcane leaf burning and returning to the field increased the content of soil available potassium in the range of 12.3-18.3 mg/kg at the early state, improved the content of alkali-hydrolyzed nitrogen and available phosphorous in the range of 5.6-20.9 mg/kg and 0.8-4.0 mg/kg, respectively, and promoted the transformation of nitrogen and phosphorus in the soil to the effective state. However, sugarcane leaf burning and returning to the field caused the loss of carbon and nitrogen elements of sugarcane leaf and brought pollution to the environment. Comprehensive analysis showed that the leaf crushing and returning to field was the most labor saving and convenient method.关键词
