The large-scale planting performance of drought resistant rice variety Hanyou 73 was combined in Donghu Production Base, Dongqiao Town, Huian County, Xiamen, Fujian Province, its “rice+vegetable” water-dry rotation cultivation techniques and its advantages in arid land were summarized and analyzed. This variety was planted in a “rice+vegetable” rotation in the research area, with a total growth period of about 128 days and resistant to bacterial leaf blight and rice blast disease, with good drought resistance; the dry grain yield of rice was 7 542.75 kg/hm2. Dryland cultivation techniques include land preparation, application of base fertilizer, and rotary tillage; after seed mixing or seedling cultivation, live broadcasting or waterless machine transplanting is carried out; arrange micro sprinkler irrigation pipe belts in the field according to the walking route of the rice transplanter wheels; after emergence, water the seedlings with water for greening, tillering, and heading filling to improve seedling quality and rice seed setting rate; according to the seedling situation in the field, apply tillering fertilizer, jointing fertilizer, and heading fertilizer to cultivate strong seedlings; dryland has more grass damage than paddy fields, and generally adopts measures such as closed weeding as the main method, chemical pesticides as auxiliary, and manual removal and remediation for prevention and control; according to local pest and disease monitoring information, timely prevention and control of diseases and pests such as sheath blight and rice planthopper. The application of the “rice+vegetable” water-dry rotation model and dryland waterless machine transplanting technology has technical management advantages such as saving labor and reducing consumption, facilitating water control, and improving fertilizer utilization efficiency; and social benefits such as improving farmland utilization efficiency, conserving water resources, and improving soil environment. This article provides a reference for the promotion and application of the “rice+vegetable” water-dry rotation model in relevant region’ dry land.
