Standard Framework and Technology Evolution

Analysis of Key Observation Technologies

Development Period Determination Criteria

Taking the spring shoot growth period of wolfberry as an example, when the new shoot length is ≥2cm, it is judged to have entered this period. It is necessary to measure on the branches of the established plants (2 branches per tree), and the threshold for judging the beginning of the group is when 10% of the branches meet the standard.

Yield determination method

Disaster classification management system

Implementation suggestions

Data quality control

• Establish a special database for wolfberry observation, and enter data according to Appendix C
• Regularly calibrate measurement tools, and branch labels should use anti-fading materials

Service application scenarios

1. Flowering period forecast combined with aphid control window period
2. Maturity period accumulated temperature model guides picking schedule

Standard formulation background

For major production areas such as Ningxia In response to the refined needs of wolfberry planting, the National Agricultural Meteorological Standards Committee (SAC/TC539) organized and compiled the autumn fruit branch observation system for the first time, filling the gap in meteorological services during the post-summer dormancy growth stage.
