: Through years of experimental research, the high-yielding cultivation techniques for rice mixed sparse planting have been summarized. Seedling throwing or thinning and drought nursery seedling (sowing amount 150g / m2) have been put forward. Seedlings have been planted on May 25 with 2 or 3 seedlings per hole. Three rows (50 0 +30 0 +30 0) cm × (2 0 0, 13 3 2 0 0) cm and (4 0 0 +30 +30) cm × 2 0 0 cm were used for transplanting. 15 8 holes / m2). Four rows of cultivation methods were selected as (50 0 +30 0 +30 0 +30 0) cm × (2 6 7,13 3,13 3,2 6 7) cm and (50 0 +30 0 +30 0 +30 0) cm × 200 cm transplanted rice planting (14 3 ~ 15 5 holes / m2). Application of nitrogen, nitrogen, phosphorus and potassium (2: 1: 1) formula fertilization, shallow-wet-run-dry irrigation
