Abstract:

The experiment studied the three different cultivation regimes of submerged irrigation, dry cultivation and ridge cultivation used the Japonica Xi-giant embryo-1 as experimental material, conventional japonica rice Hexi-22-2 as control. The grain yield and quality of Japonica Giant Embryo rice were studied under three different cultivation regimes. The results indicated that the significantly promoted effective panicles and spikelets per panicle were greatly influenced by cultivation regimes, which were correlated with yield, so the grain yield of the ridge cultivation was higher than that of the submerged irrigation and dry cultivation. The influence of different cultivation regimes to rice appearance, brown rice rate, protein content and amaylose content of Japonica Giant Embryo rice were not obvious, but to the percentage of chalky grain and chalkiness area of Japonica Giant Embryo rice were obvious. Therefore, ridge cultivation was the most beneficial cultivation regime to obtain the highest grain yield and the greatest income.
