T/AHLB 010-2024 The cultivation environment quality requirements for Mugo pennisetum

Scope

Scope: This document specifies the definition of willow production sites and environmental conditions, the requirements for site selection, ambient air quality, irrigation water quality, and soil environmental quality, as well as their concentration (content) limits and test methods. This document applies to willow production sites. Main technical content: 5. Requirements? 5.1 Site selection? Willow production sites should be selected in agricultural production areas with good ecological conditions, far from pollution sources, and with sustainable production capabilities. 5.2 Ambient air quality of production sites? The ambient air quality of willow production sites should comply with the requirements specified in Table 1. **Table 1: Concentration limits of various pollutants in the air** **Item** **Concentration limit (mg/m³)** **Total suspended particulate matter (TSP)** ≤ 0.3 **Sulfur dioxide (SO2)** ≤ 0.15–0.50 **Nitrogen dioxide (NO2)** ≤ 0.12–0.24 **Fluoride (F)** ≤ 20 **ug/m³** 5.3 Quality of irrigation water for willow production sites? The quality of irrigation water for willow production sites should comply with the requirements specified in Table 2. **Table 2: Concentration limits of various pollutants in irrigation water for willow production sites** **Item** **Concentration limit (mg/L)** **pH** 5.5–8.5 **Total mercury** ≤ 0.001 **Total cadmium** ≤ 0.005 **Total arsenic** ≤ 0.10 **Total lead** ≤ 0.10 **Hexavalent chromium** ≤ 0.10 **Fluoride** ≤ 3.00 **Cyanide** ≤ 0.50 **Petroleum hydrocarbons** ≤ 10 5.4 Soil environmental quality of willow production sites? The soil quality of willow production sites should comply with the requirements specified in Table 3. **Table 3: Concentration limits of various pollutants in soil for willow production sites** **Item** **Concentration limit (mg/kg)** **pH** 6.5–7.5 **Total mercury** ≤ 0.50 **Cadmium** ≤ 0.30
