摘要: 为有效改善多年生人工栽培甘草地表生长环境,降低成本投入,提高甘草产量和经济效益,分别以播种机地表耖土、推土机地表耖土、刀具地表耖土等机械中耕为试验处理,以大田未挠动处理为对照,对比分析不同处理对甘草农田土壤水分、紧实度、地表根系呼吸、植株光合能力,以及机械中耕后对甘草株高、产量等主要特征的影响。结果表明,播种机地表耖土和刀具地表耖土均可适度改善甘草农田土壤环境、增加产量,特别是播种机地表耖土处理增产7.43%,应结合早春田间追肥、机械除草等在5月中下旬进行,推土机地表松土作业对田间甘草苗破坏严重,不提倡应用。

Abstract: To effectively improve the perennial artificial cultivation of Glycyrrhiza uralensis farmland surface growth environment, reduce the cost and increase the yield and economic benefits, planter surface tillage, bulldozer cut root tillage and knife surface tillage were studied and compared with no tillage. The effects on main biological characteristics of soil moisture, compaction, surface root respiration, plant photosynthetic capacity, and G. uralensis height and yield were investigated. Comprehensive analysis showed that planter soil surface tillage and knife soil surface tillage were suitable mechanical tillage treatments which could improve soil environment of G. uralensis, increase production; planter soil surface tillage treatment could increase the yield by 7.43% and should be combined with early spring field fertilizers and mechanical weeding before middle or late May. Bulldozers surface tillage operation could cause serious damage to G. uralensis field, and was not recommended in application.
