蚕豆秸秆翻压还田对后作水稻化肥减施和产量的影响
Effect of Pressing and Returning Broad Bean Straw to Field on Fertilizer Application Reduction and Yield in Subsequent Rice Cultivation
摘要
Abstract
This article used a field plot experiment method,and took conventional fertilizer application treatment as the control to study the effects of three different fertilizer treatments including conventional fertilizer+broad bean straw tillage and returning to the field,80%conventional fertilizer application+broad bean straw tillage and returning to the field(T2),and 80%conventional fertilizer application+broad bean straw tillage and returning to the field+calcareous soil conditioner(80 kg/667 m2)on rice yield and soil basic fertility.The results showed that compared with the control CK,the dry matter yield of rice in T2 treatment reached 676.78 kg/667 m2,which increased by 36.46 kg/667 m2 and 5.69%.The cost of fertilizer investment decreased by 29.9 yuan/667 m2,resulting in an increase of 117.50 yuan/667 m2 in income and a 19.36%increase in economic benefits.The soil pH value,organic matter,alkali hydrolyzed nitrogen,available potassium,total nitrogen,and total phosphorus content significantly increased by 0.07,1.43 g/kg,21.82 mg/kg,17.64 mg/kg,0.17 g/kg,and 0.14 g/kg,respectively.The soil available phosphorus and total potassium content increased by 10.37 mg/kg and 0.79 g/kg,respectively.In conclusion,the optimal fertilization treatment was"80%conventional fertilizer application+returning broad bean straw",which can be popularized and applied in the"broad bean rice"rotation mode in Lianjiang County.关键词
