NY/T 742-2003

Agricultural machinery inspectors, farmers, and agricultural management departments use this standard to evaluate the plowing quality of mouldboard ploughs. It provides unified testing methods and evaluation indicators to ensure that plowing meets agronomic requirements and improves agricultural productivity. This standard is important for standardizing plough operations and ensuring land cultivation quality.

农业机械检测人员、农机用户和农机管理部门使用该标准来评估铧式犁的耕地作业质量。该标准提供了统一的检测方法和评定指标，确保耕地作业达到农艺要求，提高农业生产效率。它对于规范铧式犁作业、保障耕地质量具有重要意义。

This standard specifies evaluation indicators, detection methods, and inspection rules for the operation quality of mouldboard ploughs, applicable to field operation quality assessment for general-purpose ploughs. It requires that after plowing, local agronomic technical requirements be met, and plowing be carried out within the suitable soil tillage period with soil moisture content of 10% to 25%. Key quality indicators include average plowing depth, depth stability variation coefficient, missed plowing rate, and repeated plowing rate. Detection methods involve soil moisture measurement and instrument calibration. This standard provides a unified basis for evaluating mouldboard plough plowing quality.

本标准规定了铧式犁作业质量的评定指标、检测方法和检验规则，适用于普通用途铧式犁的田间作业质量评定。标准要求作业后满足当地农艺技术要求，并在土壤含水率10%-25%的宜耕期内进行。主要质量指标包括平均耕深、耕深稳定性变异系数、漏耕率和重耕率等。检测方法涉及土壤含水率测定和仪器检定。该标准为铧式犁耕地作业提供了统一的质量评价依据。
