摘要
通过田间小区试验方法研究不适用烟叶还田对水稻产量及经济效应研究。结果表明:不适用鲜烟叶还田能有效提高土壤有机质、速效氮含量,改善土壤环境条件,提高水稻产量。基于本地区优化施肥基础上,鲜烟叶还田的最佳用量为13252 kg/hm2。通过不适用鲜烟叶还田措施不仅能有效解决不适用鲜烟叶处理处置问题,而且有效改善土壤环境条件,实现土壤的可持续利用。
The effect of unavailable fresh tobacco leaves on rice yield and economic benefit by field testing was studied. The result showed： the agronomic measures that unavailable fresh tobacco leaves returned field could available improve soil organic matter, available nitrogen, conditions of soil environmental and rice yield. The optimal level of fresh tobacco leaves returned field was 13252 kg/hm2 basin on optimal fertilize input in Malong regional. The agronomic measures that fresh tobacco leaves returned field not only available disposal unavailable fresh tobacco leaves, but also improved conditions of soil environmental and field soil sustainable utilization.
