T/CMBN 0055-2026 Technical specification for Integrated water and fertilizer application of liquid manure in shallow-buried drip irrigation under conservation tillage for maize

Scope

This document specifies the terms and definitions, pre-operation preparations, straw mulching and tillage, shallow drip irrigation system layout, liquid manure treatment and application, integrated water and fertilizer control, field management, harvest and follow-up treatment, quality inspection, and precautions for the integrated technology of shallow drip irrigation with liquid manure application in corn protective tillage. The core objectives are to achieve soil protection, water and fertilizer conservation, quality improvement, and efficiency enhancement through technology integration, while promoting the resource utilization of livestock and poultry manure, reducing agricultural non-point source pollution, and promoting the green and sustainable development of the corn industry. This document is applicable to regions that need to implement protective tillage and have stable liquid manure resources (such as processed products of livestock and poultry manure like pigs, cattle, and sheep). Suitable soil types include loam, sandy loam, and light clay, with a soil cultivation layer thickness of ≥20cm, a pH value of 6.0 to 8.5, and good drainage conditions. It is not suitable for plots with heavy and compacted soils, poor drainage, or high groundwater levels.
