Scope

Scope: This standard specifies the environmental requirements for the production area and management techniques of Linjiang ercai, as well as testing methods, inspection rules, labeling, packaging, transportation, and storage. This standard applies to the production, management, and storage of Linjiang ercai in Chongqing and similar ecological regions. Main technical content: - Locate away from sources of pollution such as factories, hospitals, and garbage dumps. The site should be relatively flat, with convenient transportation, a pH value between 6.0 and 7.0, and deep, loose soil rich in organic matter, preferably sandy loam or loam with good water and fertilizer retention. Avoid successive planting of cruciferous vegetables and implement a 2-3-year crop rotation. Environmental conditions must meet the requirements of DB50/T39-2001. 4 Production Management 4.1 Pre-planting Preparation 4.1.1 Variety Selection: Select high-yield, high-quality, disease-resistant, and marketable varieties based on sowing time, sales markets, and soil conditions. 4.1.2 Seed Quality: The seeds must meet the requirements of GB 8079 for Class II or higher quality. 4.1.3 Bed Site Selection and Preparation: Choose a fertile, loose, sunny, and well-drained plot with minimal pests and diseases from previous crops. Before sowing, deeply loosen the soil and apply 1,000 kg of composted human and animal manure, 15 kg of superphosphate, and 50 kg of ash per mu as base fertilizer. For soils with a pH value below 6.0, mix 100-150 kg of quicklime with the soil to adjust the acidity. Dig furrows and form beds with a width of 1.3-1.5 m and a depth of 15 cm. Level the beds and create a turtleback shape. Install drainage ditches around the beds. 4.2 Sowing and Seedling Cultivation 4.2.1 Sowing Period: Linjiang ercai has strict requirements for sowing periods. Sowing too early may result in pre-flowering and small axillary buds, while sowing too late may lead to only stem growth withou
