Abstract:Based on the group-after-group sowing experimental data of 1990 and 1991 ,the photosensi tivity and thermosensitivity of the direct seeding rice in dry land and the relations between the percentage of the inperfect grain and the factors of illumination and temperature are analysed. And also some agrometerological problems such as the best time for safe sowing,the best time for safe head sprouting, arid ect. are resolved according to the local climate. All these results could provide scientific basis for further popularity of the direct seeding rice in dry land.
