　　Introduction

　　Suizhou Bubble Green, also called black-oil Chinese cabbage, is a unique local variety from Zengdu District in Suizhou. It is a low-growing plant with leaves that are dark green to nearly black, bubble-shaped, uniformly dark, thick and tender in texture, and highly resistant to cold. Its quality improves significantly after exposure to frost and snow, and it is one of the most beloved vegetables for residents during the Spring Festival season, typically available around that time. Due to its cold resistance, it is generally grown as an overwintering crop in open fields, with staggered sowing beginning in mid to late September, and harvesting and marketing from November through February or March of the following year. It begins to bolt and flower after the beginning of spring. Thanks to its unique quality and rich nutrition, Bubble Green is widely cultivated in the Suizhou area, with an annual planting area of about 50,000 mu, yielding approximately 1,000 kilograms of fresh vegetables per mu, totaling around 50,000 tons of fresh produce annually, with a total output value of about 50 million yuan. In the past, Bubble Green was mainly sold within the region. In recent years, with increased population mobility, it has gradually gained fame both within and outside the province, even becoming a gift that Suizhou locals offer to honored guests or friends and relatives from other regions. Suizhou “Bubble Green” is the region’s leading cultivated variety, boasting a long history of cultivation. It is a winter-hardy herbaceous plant of the non-heading Chinese cabbage type in the Brassica family, primarily consumed for its tender leaves, though the young stems can also be eaten later in the growth cycle. It is rich in protein, fat, carbohydrates, carotene, vitamins, and minerals. Suizhou “Bubble Green” has obtained green food certification issued by the National Ministry of Agriculture. Inspection reports from the Wuhan-based Food Quality Supervision and Testing Center of the Ministry of Agriculture show that this product is rich in nutrients and qualifies as pollution-free green food.
