This paper summarized the high efficiency open-field cultivation techniques for the three crops a year system of potatoes, cabbages and radishes in the western Shandong area, and analyzed the economic benefits of this system. The crop arrangement is as follows: potatoes are sown from late February to early March and harvested in mid-to-late June; cabbage is transplanted in early July and harvested in late August; radish is sown in late August and harvested from late October to early November. The key cultivation techniques for potatoes include selecting early-maturing, stress-tolerant and high quality varieties such as Favorita, cutting seed potatoes into pieces with 1–2 buds each, dressing seeds with 20 mL of 60% imidacloprid and 50 g of 50% propineb, accelerating germination at 20 ℃ and 75%–90% relative humidity, applying 30 000 kg/hm² of decomposed organic fertilizer followed by deep ploughing and double-row planting, carrying out proper earthing-up and precise water and fertilizer management, and applying 45–75 kg/hm² of high-nitrogen water-soluble fertilizer with irrigation after seedling emergence. Late blight, aphids and other pests are controlled with 25% azoxystrobin SC 1 200-fold dilution and 5% acetamiprid EC 1 500-fold dilution. For cabbage cultivation, heat-tolerant and disease-resistant varieties such as Aoqina are adopted; seedlings are raised in special substrate and germinated in a germination chamber after sowing. Previous crop residues are removed before transplanting, and transplanting is conducted on sunny or cloudy days. Topdressing is applied at proper stages: 75 kg/hm² of high-nitrogen water-soluble fertilizer after seedling recovery. Soft rot, third-instar larvae of Plutella xylostella and other pests are controlled with 50% asomate AS 800-fold dilution and 5% chlorfluazuron EC 1 500-fold dilution. For radish cultivation, disease-resistant mid-early-maturing varieties such as Jieruqiu 158 are selected. A total of 15 000 kg/hm² of decomposed organic fertilizer is applied, and high-ridge cultivation and mechanical sowing are adopted. Soil moisture is maintained at alternating dry and wet conditions, and 75 kg/hm² of balanced water-soluble fertilizer is topdressed at the 6–8-leaf seedling stage. Downy mildew, aphids and other diseases and pests were controlled using 500-fold dilutions of 66.5% propamocarb hydrochloride AS and 1 500-fold dilutions of imidacloprid WP. The potato–cabbage–radish cropping system improves land use efficiency and economic benefits. This paper provides a reference for efficient vegetable production in similar regions.
