This is Giant Juncao grass, a variety of Juncao. 

Traditionally, mushrooms like shiitake and polypore require 15-20 years of tree growth. With Juncao, we can cultivate any mushroom artificially - with superior quality.

These Juncao-grown polypore resemble deer antlers (hence their Chinese name). Benefits are clear: no tree-cutting means less deforestation, plus higher medicinal content. Using Juncao for shiitake could save 8.3 million m³ of wood yearly. For boards, 75 million m³ annually.

Iris Wong: Do cows like Juncao? I'll feed them some now.

These calves are six months old. Our dairy cows eat three meals daily - just like humans.

Juncao feeds 5,000 dairy cows here. 

Juncao is our primary feed, cutting costs dramatically while enabling recycling.

Their large Juncao base uses smart irrigation.

With my phone, I can target specific areas for precise irrigation. 

Iris Wong: This farm's eco-cycle combines agriculture and livestock. Automated scrapers clean manure, separating it into solid bedding and liquid fertilizer. Biogas from fermentation is captured and reused - a complete sustainable cycle.

Livestock generates 15% of global emissions - over 60% from cattle. Their digestive gases and manure act like car exhaust, releasing greenhouse gases.

Juncao feed improves cows' gut health, boosts efficiency, and reduces methane. 

From mushrooms to livestock, Juncao's circular model benefits both environment and profits.
