Development and testing of in-situ combined operation machine for subsoiling,fertilization and soil preparation
摘要
Abstract
To address the current challenge of failing to break through deep soil resistance layers during saline-alkali land reclamation,a specialized reclamation device was developed.Equipped with multiple spiral deep-loosening shafts,the device employs counter-rotating adjacent shafts to break through saline-alkali soil resistance layers without disrupting soil structure.Powered by a wheeled tractor via a three-point hitch,the device drives the deep-loosening,fertilizing,and rolling units through the tractor's power take-off shaft.This enables integrated in-situ deep loose-ning,fertilization,and land preparation operations on saline-alkali soils.Driven by the tractor's power take-off shaft,it operates the deep loosening,fertilizing,and rolling units,enabling integrated in-situ deep loosening,fertiliza-tion,and land preparation on saline-alkali soils.Test results indicate the device achieves a subsoiling depth of 68.49 cm,with subsoiling stability at 98.09%,soil fragmentation rate at 99.17%,vertical soil displacement of 8.6 cm,post-tillage surface levelness of 1.42%,coefficient of variation for fertilizer application uniformity across rows at 1.485%,and reliability assessment at 94.4%.The in-situ deep loosening,fertilization,and land preparation com-bined machine features a compact structure.Relevant test data meet design requirements,demonstrating significant po-tential for further promotion.关键词
