3 Terms and definitions

The following terms and definitions apply to this document.

Early bamboo Phyllosachysviolascens Also known as Lei Zhu. It is native to Zhejiang and Anhui, and is located in the hilly plains of northwest Zhejiang, Lin'an, Yuhang and Deqing. Introduction the regions are mainly in Jiangsu, Shanghai, Fujian, Hunan, Jiangxi, Guizhou and other places.

Covering mulch

Use bamboo leaves, alfalfa, straw and other materials to cover the bamboo shoots in the bamboo garden after 5a~6a.

Covering bamboo shoots mulchingshoots Bamboo shoots that were unearthed early by covering measures.

Shooting point fertilization fertilizationinthebambooshoothole Apply a small amount of fertilizer to the bamboo shoots after the bamboo shoots, and then cover the soil.

4 Bamboo shoot production indicators

4.1 The yield index of high-yielding forest shoots is >=22.5t/hm2.

4.2 The yield index of uncovered high-yield forest shoots is >=15t/hm2.
