土壤强还原处理对连作辣椒产量、品质和土壤养分的影响
The Effect of Soil Strong Reduction Treatment on the Yield,Quality,and Soil Nutrients of Continuous Cropping Peppers
摘要
Abstract
[Objective]The reduced soil disinformation(RSD)treatment technology has been shown to effectively restore degraded soil,but its field effects when using pepper straw remain unclear.This study aim to investigate the effects of various organic material-based strong reduction treatments on the yield,quality,and soil nutrients of continuously cultivated chili peppers.[Method]A field plot experiment was conducted on continuous cropping soil of peppers with four treatments:① CK(no organic materi-als);② RSD1(pepper straw);③ RSD2(rice straw);④ RSD3(equal mass of pepper and rice straw).A comprehensive evaluation of the pepper continuous cropping system under RSD treatment was per-formed.[Result]Compared to the CK treatment,the RSD treatments significantly increased both the root and shoot dry weight of the peppers,while substantially reducing the field-wide incidence rate of dis-eases in continuously cropped peppers.Among the treatments,RSD3 exhibited the highest shoot dry weight and the lowest disease incidence rate(29.51%).Additionally,the RSD treatments significantly enhanced the photosynthesis rate of peppers,thereby improving photosynthetic efficiency.The RSD treat-ments also had a positive impact on both yield and quality.Notably,the soil's available potassium con-tent was highest under the RSD3 treatment,increasing by 17.67%compared to the CK treatment.A com-prehensive evaluation of the pepper continuous cropping system under different RSD treatments revealed that,compared to CK,RSD treatments effectively promoted growth,increased yield,improved quality,and reduced disease incidence.However,the performance of different organic material treatments var-ied.[Conclusion]Considering growth,yield,quality,and soil fertility,the RSD3 treatment,which uti-lized a mixture of pepper straw and rice straw as raw materials,demonstrated the most balanced perfor-mance in promoting pepper growth,increasing yield and quality,and improving soil fertility under the ex-perimental conditions.关键词
