T/JXTSS 001-2026 Technical Regulation for Annual Green Manure Intercropping Combinations in Tea Plantations to Enrich Soil and Cultivate Land

Scope

This document applies to all types of tea gardens in Jiangxi Province with the main objectives of improving soil quality and enhancing land fertility, especially those with poor soil quality, low organic matter content, and high risk of water and soil erosion. This document specifies the terms and definitions, green manure varieties selection, green manure combination configuration, and key technical points of the annual intercropping green manure combination and soil fertility improvement technology for tea gardens. The main technical content includes: 1. Green manure variety selection and combination is the core. The selection of green manure varieties should meet the "Five No" principles, namely: (1) The natural growth cycle of green manure should not be higher than the height of the tea tree canopy (≤60cm). (2) The stems and vines of green manure should not climb or wrap around the tea rows. (3) The fresh grass yield of each green manure crop should not be less than 500 kg/667m2. (4) Green manure should not induce tea tree pests and diseases during its growth cycle. (5) Green manure has shallow root systems and does not compete intensely with tea trees for water and nutrients. Legume green manure is preferred. According to the above principles, the recommended winter green manure varieties include: purple clover (Leguminosae), white clover (Leguminosae), golden flower (Leguminosae), rat grass (Poaceae), early oat (Poaceae), February blue (Cruciferae), motherwort (Plantaginaceae), and cornflower (Asteraceae); summer green manure includes: peanut (Leguminosae), Fujian-bred round-leaved cassia (Leguminosae), ground-cover indigo (Leguminosae), baume root (Leguminosae), Baixi grass (Poaceae), and peacock grass (Asteraceae). The recommended combination schemes include: "Leguminosae + Leguminosae" for soil fertility improvement, "Leguminosae + Poaceae" for functional complementation, and "Leguminosae + Asteraceae" for ecological tourism. 2.
