[the text] technical guidelines for the export of frozen spinach cultivation and the spinach quality standard 1. The main content and the main content of the application criteria set out the environmental conditions for the construction of export spinach bases, the technical protocols to be followed for the export of spinach production and the quality standards for spinach. This applies to the non-hazardous production of frozen spinach raw materials and the acquisition of vegetable production. 2. A provision which, by reference to the criteria below, constitutes the standard by reference to them. At the time of publication, the versions indicated were valid. All the standards will be revised, and the parties using this standard should explore the possibility of using the latest versions of the following standards.

Vegetable is a spinach-free agricultural product that meets the requirements of a non-hazardous agricultural product. The export of spinach is the production of spinach agricultural products that meet export requirements or meet the requirements for the export of frozen spinach raw materials for processing. 4. Specific project concentration limits (average 1h daily) mg/m3 total suspended particulate matter (standard status) ≤ mg/m3 sulphur dioxide so2 (standard status) ≤ mg/m3 no2 (standard status)≤ mg/m3 fluoride f (standard status)()() control measures plant mines that are prone to pollution, such as fire-free power plants, furnaces, chemical plants, cement plants, etc., are located around the site, especially within 2 km of the prevailing wind. The land is at least 100 metres away from the main arteries. The project concentration limit (mg/l) ph of the standard for the quality of irrigated water (mg/l) is set at 150% of the total chemical oxygen demand of the total mercury glycium glycium glyceride (cycyanide) 6-priced chromium fluoride (cyclide) of the petroleum type chromium coliform 1000(s/l) control measures surface water sources and upstream tributaries do not have any plants that can cause pollution of water bodies, printing plants, pharmaceutical plants, tanneries, paper factories, fertilizer plants, chemical plants, etc. Irrigated by industrial wastewater, household sewage and excreta, which are treated and used after meeting standards.
