本文系统总结了花椰菜套种南瓜的绿色高效栽培技术。该模式应选择pH 6～7、土层深厚、排灌方便的砂质壤土，且前茬为非十字花科作物的地块。花椰菜选用宝岛青梗等抗逆性强的品种，于11月下旬至12月育苗，翌年2月初定植；南瓜选用墨宝南瓜等品种，于2月上旬育苗；二者于3月上旬开始套种，采用“两畦花椰菜、一畦南瓜”的套种方式，以提高土地利用率，并充分利用光热资源。花椰菜采用穴盘育苗，5～6片真叶时选阴天或晴天下午定植，行株距50 cm×25 cm；基肥以硫酸钾型复合肥（750 kg/hm²）、有机肥（7 500 kg/hm²）及硼砂（7.5 kg/hm²）为主，移栽后7 d追施硝酸铵钙（225 kg/hm²），莲座期追施复合肥（150 kg/hm²）；定植后勤浇水促缓苗，生长期保持土壤湿润，雨季注意排水；病虫害防治以农业、物理及生物措施为主，化学防治为辅，具体包括适时中耕除草、清洁田园，悬挂诱虫板等诱杀虫害以及喷施68%精甲霜·锰锌、苏云金杆菌等药剂防治霜霉病和菜青虫；花球充分膨大、紧实时采收。南瓜采用穴盘育苗，3～4片真叶时定植；5片叶时摘心，选留4～5条健壮侧蔓，蔓长50～70 cm时引蔓压蔓；水分管理遵循“前控、中促、后控”原则，挂果期保障供水，采前10 d停水；选用芽孢杆菌、代森锌和吡虫啉等防治疫病、霜霉病、地老虎；果实表皮厚实、蜡粉明显时采收。该套种模式有效利用了光热与土地资源，实现了增产增效与绿色生产的统一，具有良好的经济效益与生态效益。

The green and efficient cultivation techniques for the intercropping of Brassica oleracea and Cucurbita moschata were systematically summarized and analyzed. This model should choosen sandy loam soil with a pH of 6-7, deep soil layers, convenient irrigation and drainage, and a previous crop that was non cruciferous plant. For Brassica oleracea, varieties with strong stress resistance were selected, such as Baodaoqinggeng. Seedlings were raised from late November to December, and transplanted in early February of the following year. For Cucurbita moschata, varieties such as Mobaonangua were selected, with seedlings raised in early February. Intercropping begins in early March, adopting a configuration of “two ridges of Brassica oleracea, one ridge of Cucurbita moschata”, to improve land use efficiency and fully utilize solar and thermal resources. Brassica oleracea seedlings were cultivated using plug trays and transplanted on overcast days or in the afternoon of sunny days when they had developed 5-6 true leaves, with a planting spacing of 50 cm between rows and 25 cm between plants. Base fertilization primarily consists of sulfate of potash compound fertilizer (750 kg/hm²), organic fertilizer (7 500 kg/hm²), and borax (7.5 kg/hm²). Seven days after transplanting, calcium ammonium nitrate (225 kg/hm²) was applied as a topdressing, followed by an additional application of compound fertilizer (150 kg/hm²) during the rosette stage. After transplanting, frequent watering was carried out to promote seedling establishment, while soil moisture was maintained during the growth period, with particular attention to drainage during the rainy season. The prevention and control of pests and diseases were mainly based on agricultural, physical, and biological measures, supplemented by chemical control. Specifically, this includes timely plowing and weeding, cleaning the fields, hanging insect traps, and spraying 68% metalaxyl-M·mancozeb and Bacillus thuringiensis to control downy mildew and cabbage green pests. Harvesting takes place when the curds were fully expanded and firm. Cucurbita moschata seedlings were raised using plug trays and transplanted when they develop 3-4 true leaves. When the plants reach the 5-leaf stage, the growing tips were pinched, and 4-5 robust lateral vines were selected and retained. Once the vines reach 50-70 cm in length, they were guided and pinned down to promote rooting. Water management follows the principle of “restricting early, promoting during mid-growth, and restricting later”. During the fruiting period, adequate water supply was ensured, while irrigation was halted 10 days before harvest. For disease control, Bacillus spp., zineb, and imidacloprid were used to manage diseases such as phytophthora blight, downy mildew, and cutworms. The fruits were harvested when the skin became thick and a distinct waxy bloom was evident. This intercropping model effectively utilizes light, heat, and land resources, achieving a balance between increased yield and efficiency and green production, with significant economic and ecological benefits.
