摘要
Abstract
Returning corn straw to the field not only enables the efficient resource utilization of agricultural waste,but also effectively improves the soil fertility decline and functional degradation caused by unreasonable field management during tobacco cultivation.This experiment set four treatments(straw deep burial,subsoiling,Fenlong depth of 30 cm,and Fenlong depth of 50 cm)to investigate the effects of different corn straw returning methods on soil chemical properties and tobacco yield.The results showed that the soil organic matter,nitrate nitrogen,ammonium nitrogen,available potassium,and soil carbon nitrogen ratio were most effectively improved in the treatment of Fenlong depth of 50 cm;there was no significant difference in the contents of nitrogen and phosphorus in tobacco leaves among different treatments,while the tobacco yield was higher in treatments of subsoiling and Fenlong depth of 50 cm;the proportion of upper grade tobacco was the highest in Fenlong depth of 50 cm treatment,while the production value of tobacco was higher in treatments of subsoiling and Fenlong depth of 50 cm.Therefore,the method of corn straw returning to the field with Fenlong depth of 50 cm could effectively increase the soil nutrient content,improve the tobacco leaf quality,and significantly increase tobacco production value.关键词
