采用近几十年来国内外研究优质米形成与气候条件关系得到的主要成果以及四湖地区腹地荆州市 1954～ 1999年共 4 6年来的气象资料 ,以平均温度为主要影响因子 ,以日照时数、气温日较差、降雨量为协同影响因子 ,以一季中稻为主要研究对象 ,以其齐穗后 15～ 2 0天为关键生育期 ,对本地区水稻优质米形成的适宜抽穗期的气候条件进行了初步探讨。结果表明 ,8月 2 5日至 9月初齐穗为四湖地区优质米形成的最佳齐穗期 ,8月 2 2日至 9月 5日齐穗为四湖地区优质米形成的适宜齐穗期 ,8月 10日前与 9月 9日后齐穗不利于四湖地区优质米的形成。
Based on the main achievements of the research on the relationship between the quality of rice and the climatic conditions at home and abroad in recent decades and the meteorological data of Jingzhou City from 1954 to 1999 in the hinterland of four lakes for a total of 46 years, the average temperature was taken as the main influence factor, , The temperature day is poor and the rainfall is the synergistic influencing factor. Taking the middle season as the main research object, with its 15-20 days after heading, the climatic conditions suitable for the formation of good quality rice in this region A preliminary discussion. The results showed that Qi spike was the best heading stage for high-quality rice formation in Sihu area from August 25 to early September. From August 22 to September 5, Qi-spike was the suitable heading for good-quality rice formation in Sihu Region The period before August 10 and September 9 after heading is not conducive to the formation of high-quality rice in the Four Lakes.
