Direct-seeded rice cultivation has important practical significance for adapting to the reform of rural economic system, saving manpower and material resources, improving the unit yield of rice and adjusting crop planting structure. First, the test results and economic benefits Since 1981, we conducted a five-year continuous rice double-seeding cultivation techniques research, carried out in the screening of varieties, suitable sowing time, different sowing methods, with different herbicides with different fertilizer levels and In different sowing set up transplanting as the control of the best combination of matching and main fertility indicators, Ota broadcast and field transplanting comprehensive cultivation techniques and economic
