Scope

Scope: This document specifies the terminology definitions, site environment, land preparation and fertilization, ridge formation and film covering, rainwater collection on the film surface, timely sowing, field management, and mechanical harvesting norms for potato film-covered rainwater collection cultivation technology in arid and semi-arid areas of Ningxia. This document is applicable to potato production in arid and semi-arid areas of Ningxia. Main technical content: 3. Terms and definitions The following terms and definitions apply to this document. 3.1 Film-covered rainwater collection In arid and semi-arid areas, by using specialized machinery to form "M"-shaped ridges and cover them with film, with cultivation strips on both sides and a rainwater collection surface in the middle, and drilling irrigation holes in the middle (see Figure 1). 3.2 Simplified cultivation Using specialized machinery to complete fertilization, ridge formation, film covering, and sowing in one go, followed by backfilling after sowing, and achieving mechanized spraying, fertilization, and harvesting. 4. Site environment In arid and semi-arid areas, it is advisable to select soils with loose, fertile, and deep layers; soils such as yellow loam and black loam with a texture of loam or light loam, and an organic matter content ≥12 g/kg. Specifically, refer to NY/T 391-2021. 5. Land preparation and fertilization 5.1 Mechanical land preparation Deep plowing with a plowing depth of more than 30 cm, followed by harrowing. Specifically, refer to NY/T 3483-2019. 5.2 Sufficient base fertilization Combine land preparation with sufficient base fertilization. Based on a potato yield of 2,000 kg/667 m2, the fertilizer dosage is determined as follows: - In autumn, in combination with land plowing, apply 1,200–1,500 kg/667 m2 of composted farmyard manure (chicken manure), 1,500–2,000 kg/667 m2 of sheep manure, or 2,000–2,500 kg/667 m2 of cow manure; - 20–25 kg/667 m2
