Raw rice ratio was strongly influenced by the weather service, which forecast service TV3, TV2 has a high rate of raw rice; the lowest service rate, TV5 raw rice reached 70%. This result is consistent with many resources indicate that the temperature in the period of 30 days after the rice well important influence to the quality of rice, high temperatures reduce the rate of raw rice [4], [7]. Amylose content of affected rice quality, nowadays people tend to be the favorite of rice amylose content below 20%. Through the results of table 5, we saw the weather service markedly influence to the amylose content, amylose content tends to increase progressively according to the increase of the time of service. This can be explained by temperature in the service late in stage nine high amylose content increases. High temperature during ripening stage do amylose synthesis enzyme activities of pectin decreased activity therefore increases the amount of amylose [5] White-silver ratios are related closely with raw rice ratio, the proportion of large silver white makes the rate decrease, due to raw rice starch particles loose and arrange discrete, causes abdominal silver make prone rice broke down when milling [3]. White silver rate due to regulatory genes but also the many affected by the environment. At the time of service TV4, TV5 meets the high temperature in the ripe stage makes the white rate of silver increased dramatically, the white rate was lowest Silver Service TV1 (0.05). All three temporary TV1, TV2, TV3 has silver white rate 1.0 point, heading slightly < silver, however in very small proportions.
