T You 78 89 is a key promotion combination for early rice with good quality in Fujian Province.In this study, 4 different fertilization methods, 4 different planting densities, and 5 different basic seedling planting and transplanting transplanting methods The results showed that the total fertilization amount of T You 7889 was 60% of basal fertilizer, 20% of tillering fertilizer, 10% of panicle fertilizer and 10% of granulation fertilizer, and the planting specifications were 200 mm × 20.0 cm. The yield was 752 2.5 kg · hm-2. Under the same conditions of 750,000 basal hectares per hectare, the transplanting of seedlings was 6.4% more than the transplanted seedlings.
