Recently, the Cotton Wisdom Cultivation Innovation Team of the Cotton Research Institute of the Chinese Academy of Agricultural Sciences has carried out research on intercropping green manure in cotton fields
.

They found that cotton - February orchid with reduced nitrogen fertilizer can promote carbon sequestration cotton production system, emission reduction, low nitrogen and sustainable development, will help our country in cotton production "carbon neutral"

Single-cropping cotton is the main cotton planting system in the Yellow River Basin in China, but it will cause waste of land and natural resources, high greenhouse gas emissions, and serious loss of active nitrogen
.

Using February orchid as a green manure crop to replace winter fallow in cotton production is a new planting system, but its sustainability has not yet been verified

The study conducted a life cycle assessment of two cropping systems under different nitrogen application rates to estimate carbon footprint, nitrogen footprint, and net ecosystem economic benefits
.

The results show that the February orchid coverage reduces the carbon footprint per unit area of the system

—

The study proposes that in the Yellow River Basin and other areas with similar ecological conditions, adopting a comprehensive strategy combining February orchid as a cotton field winter green manure and reducing nitrogen fertilizer application can promote the green, low-carbon, low-nitrogen and sustainable cotton production system.

The research was funded by the National Natural Science Foundation of China and other projects
