Issues and Objectives

Here is the English translation: The Xinfeng Township area in Hsinchu County was affected by irrigation suspension during the first crop season in the past. Although the government would notify farmers in advance of possible water-saving measures for the first crop season, farmers have to decide whether to start seedling cultivation as early as early January, so this information is of limited help to them. Moreover, when drought occurs, the government provides subsidies to landowners, which does not directly benefit farmers who lease farmland. In addition, when the temperature for rice seedlings drops below 7 degrees Celsius, the roots are not yet established after transplanting, making the seedlings less resistant to cold.

Improvement Measures Taken

Mechanically break up the plow pan; after seed pre-treatment, directly drill-seed in rows in a non-flooded (dry) field, then return to conventional cultivation once the rice reaches the three-leaf stage.

Results

In the early stages, water consumption for rice cultivation is reduced by relying solely on spring and plum rains. Furthermore, labor costs are lowered due to the reduced frequency of land preparation and the elimination of the seedling nursery phase. During the same period, the yield from conventional transplanting was approximately 14,000 jin, while the yield from direct seeding was 12,000 jin, slightly lower than that of conventional transplanting.
