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。
Study on Yield and Economic Effect of Rice Returning Paddy Field Not Suitable for Application by Field Test Method. The results showed that applying non-fresh tobacco leaves to the field could effectively increase soil organic matter and available nitrogen, improve soil environmental conditions and increase rice yield. Based on the optimized fertilization in this region, the optimum amount of fresh tobacco to soil was 13252 kg / hm2. By not applying fresh tobacco to the field measures not only can effectively solve the problem of not dealing with fresh tobacco leaves, but also effectively improve the soil environmental conditions and achieve the sustainable use of soil.
