摘  要:
The results of the experiments of 1999-2001 showed that the optimum sowing time of rice was as the follows:Around March 3rd in the southern part of northern Guangxi and around March 10th in the northern part of northern Guangxi for the early rice while the best sowing time for the late rice was June 25th . The seedling age was 40-45days and the leaf age was 4-5 leaves for the early rice .The seedling age and leaf age were 20-25days and 4.4-5.5 leaves respectively for the late rice. Throwing cultivation was beneficial to the high output and excellent quality of rice of excellent quality. As for throwing cultivation, the optimum density was 20 thousand-22 thousand holes/667m 2 for early rice and 22 thousand-24 thousand holes/667m 2 for late rice. The optimum ratio of basic fertilizer, tillering fertilizer and ear granular fertilizer was 6∶2∶2. When ears were up to 80-90% of the available ears in the available tillering period, to expose the paddy field to the sun after draining was comparatively suitable.
