Pengguang: This document was first published in:2009 and this is the first revision:IntroductionThe core content of conservation tillage is to implement no-tillage or minimum tillage, reduce the intensity and frequency of soil tillage as much as possible, and use crop straw and Stubble covering protects the ground surface, and at the same time, corresponding agronomic cultivation techniques are used to protect the output capacity of the natural functions of the soil: production methods, improve drought resistance, increase farmers' income, reduce straw burning, improve the ecological environment, promote sustainable agricultural development, and protect arable land The realization of conservation tillage is inseparable from the technical support of high-quality agricultural equipment: It requires agricultural equipment with different working conditions and working performance to complete the work: Therefore, conservation tillage standards are formed according to different types of operations: system: GB/T 24675 consists of the following parts: --- Part 1: Shallow tillage machine: The purpose is to give complete technical requirements and test evaluation methods for shallow tillage machines for conservation tillage: This method provides a standard basis for the manufacturing and product upgrading of shallow loosening machines: --- Part 2: Subsoilers: The purpose is to provide complete technical requirements and test evaluation methods for subsoilers for conservation tillage: The method provides a standard basis for the manufacturing and product upgrading of deep tillage machines: --- Part 3: Spring-tooth harrows: The purpose is to provide complete technical requirements and test evaluation methods for spring-tooth harrows for conservation tillage: This method provides a standard basis for the manufacturing and product upgrading of spring-tooth harrows: --- Part 4: Disc harrows: The purpose is to give complete technical requirements and test evaluation methods for disc harrows for conservation tillage: This method provides a standard basis for the manufacture and product upgrading of disc harrows: --- Part 5: Stubble crushing and returning machine: The purpose is to give a complete technical description of the stubble crushing and returning machine for conservation tillage: The sum test evaluation method provides a standard basis for the manufacturing and product upgrading of stubble crushing and returning machines: --- Part 6: Straw chopping and returning machine: The purpose is to give a complete technical description of the straw chopping and returning machine for conservation tillage: The sum test evaluation method provides a standard basis for the manufacturing and product upgrading of straw crushing and returning machines: This document is part 2 of GB/T 24675 and is aimed at the impact of large amounts of straw and stubble left on the land after conservation tillage harvest: Influenced by the characteristics of no-till seeding, the technical requirements and test evaluation methods of conservation tillage subsoilers are fully given, which provides a reference for the manufacture and production of subsoilers: Provide standard basis for product upgrades: Conservation tillage machinery: Part 2: Subsoilers1 ScopeThis document specifies the product model, technical requirements,
