Introduction
The core content of conservation tillage is to implement no-till or less tillage, to reduce the intensity and frequency of soil tillage as much as possible, and to use crop straw:
Cover the surface with stubble to protect the surface, and support the corresponding agronomic cultivation techniques to protect the output capacity of the natural function of the soil: for reforming traditional
industrial production methods, improve drought resistance, increase farmers' income, improve the ecological environment, promote sustainable agricultural development, and protect cultivated land resources:
Important strategic significance and far-reaching historical significance: It has been widely popularized in my country, and the realization of conservation tillage is inseparable from agronomic farming:
The technical support of industrial equipment requires the cooperation of agricultural equipment with different operating conditions and performance: Therefore, the protection is composed of different types of operations:
Sexual farming standard system:
GB/T 24675 "Conservation tillage machinery" consists of the following parts:
--- Part 1: Shallow loosening machine;
--- Part 2: Subsoilers;
--- Part 3: Spring tines;
--- Part 4: Disc harrows;
--- Part 5: Stubble crushing and returning machine;
--- Part 6: Straw crushing and returning machines:
This document is part 5 of GB/T 24675, which is aimed at the special characteristics of the conservation tillage that leave a large amount of stubble on the land after harvest and affect no-tillage sowing:
The technical requirements and test evaluation methods of the stubble crushing and returning machine for conservation tillage are completely given, which is helpful for the manufacture and application of the stubble crushing and returning machine for conservation tillage:
Product upgrades provide a standard basis:
