Introduction

Interpretation of the core content of the standard

GB/T 45691-2025 standard system specifies the full-chain technical requirements of Majiang blueberry geographical indication products, mainly including:

  • Origin limitation: 16 county-level administrative regions (107°17′20″~109°35′24″ east longitude, 25°19′20″~27°31′40″ north latitude)
  • Environmental requirements: 350-850m above sea level, acidic soil with a pH of 4.5-5.6, and annual precipitation of 1000-1600mm
  • Variety range: 4 main cultivated varieties, including powder blue, brilliant, garden blue, and blue rain

Comparison of key technical indicators

Variety Anthocyanin(mg/100g) Soluble solids(%) Single fruit weight(g) Harvest period
Brilliant ≥150 ≥10 ≥1.2 Mid-June-Late July
Powder blue ≥210 ≥9 ≥0.8 Early July-Mid-August
园蓝 ≥300 ≥12 ≥0.6 Early July-Mid-August
蓝雨 ≥150 ≥10 ≥0.6 Early June-Late June

Standardized planting points

Cultivation management specifications

  1. Land preparation standards: Horizontal strip land preparation around the slope, depth ≥40cm, ridge height 20-30cm
  2. Planting density: ≤4500 plants/hectare, plant spacing 120-150cm, row spacing 200-250cm
  3. Fertilization requirements: Annual application of decomposed organic fertilizer ≥45t/hectare, mainly acidic fertilizer

Key to quality control

  • The fruit skin must turn dark blue when harvested
  • The refrigerated transportation temperature is strictly controlled at 1-3℃
  • The packaging must be marked with a special geographical indication mark

Suggestions for the implementation of the standard

It is recommended that production companies focus on the following:

  • Establish a variety traceability system to ensure that the seedlings meet the 2-4 year age requirement
  • Regularly test soil pH and organic matter content (≥5%)
  • Implement differentiated harvesting management according to the characteristics of different varieties
  • Equipped with professional testing equipment (such as high performance liquid chromatography) to test anthocyanins
