T/NJ 1201-2020 Total mechanization of lettuce production in the open field: Technical regulations
Basic Information
Scope
Scope: This document specifies the general requirements for the mechanized production of open-field lettuce, including tillage and leveling, sowing and seedling cultivation, transplanting, field management, harvesting, and major mechanized operation techniques for clearing the field. This document is applicable to open-field loose-leaf lettuce, ball-shaped lettuce in ridges, and mechanized production with film mulching. Other planting methods, such as flat-bed planting and mechanized planting without film mulching, can be referenced for implementation.
