The "The Technical Specifications of the Quality Evaluation of Greenhouse Plant Freight" by the National Agricultural Rural Ministry has been officially implemented on November 1, 2020, and the agricultural rural ministry is approved as an agricultural industry standard for the People's Republic of China.
This standard is led by the Agricultural Rural Department Planning and Design Institute. A number of representative plant fill light R & D production units in the industry participate in drafting.
The standards are clearly defined on the terms, basic requirements, quality requirements, detection methods and rules of greenhouse plant fill light. The quality assessment of high pressure sodium lamps and LED lamps for plant growth, other light source plant fill lights can also be used, guided and promoted the facility horticultural industry towards high quality, high-efficiency, low energy.

Plant fill light performance requirements
This standard has made a clear requirement for the three major performance indicators of plant fetch products - electrical characteristics, optical characteristics and life.
In terms of electrical characteristics, this specification specifies the initial power value to be 90% to 100% of the rated power; the specified power factor is ≥0.90. In terms of optical characteristics, the specification is a photon flux of photosynthetic photon flux (referred to as PPF, which can use the wavelength of 280 nm ~ 800 nm in photon flux), photon flux performance (referred to as PPE, plant fill light unit power unit time The performance requirements of the selected photons are required, requiring the PPF initial value of the plant fill light to not below 90% of the nominal value, and the PPE of the high-pressure sodium lamp is not less than 1.0μmol / (s · w), LED light The PPE is not less than 1.5 μmol / (s · w). Life life is also one of the performance of key products. Standard requires that plant fill lights should be at least 90% of the lifetime of photon flux, and 90% of the life of the rated (nominal), and specifying high pressure sodium lamp estimate or measured 20000H photon flux maintenance rate is not less than 70%. , LED lamps are calculated or measured at 30000h optimal width maintenance rate of less than 70%. In addition, standards specify corresponding detection methods for different performance indicators. This standard also requires at least labeled source markers, rated voltages (V), rated power (W), IP digital marks, product models, CCC markers, etc.
Plant fill light is an important component of greenhouse light environment regulation. With the gradual promotion of greenhouse plant fill light applications, there are more and more applications in flowers, autumn and winter season, melons, strawberries and other facilities. However, compared with some countries in Europe and the United States, domestic lack of greenhouse plant fill light quality evaluation standards, in addition to the variety of filling, the quality is uneven, leading to the blindness of user procurement, poor filling effect, energy waste, etc. Cause plant fill light market chaos, industry health development is blocked.
The formulation of this standard will regulate the greenhouse plant fill market to some extent, which is conducive to the healthy development of the two major industries of plant fill light and facilities.
