摘要
通过分期播种试验，研究播期对两系杂交稻加工品质的影响及影响加工品质的主要气候因素，结果表明：1播期对加工品质性状影响大小为：整精米率＞精米率＞糙米率2多数供试两系组合早季播种其加工品质优于汕优63，但其稳定性不及汕优63，3．泸州7~8月的连晴高温天气是影响两系杂交稻加工品质的主要气候因素。
The paper reports the effects of main climate factors anddifferent sowing dates on milling quality of two-line hybrid rice grain.The results show that (1 ) effects of sowing dates on characteristics ofmilling quality arrange whole rnilled rice rate>milled rice rate>brown ricerate, (2 ) miIIing qualities of the most of two-line hybrid rice seeded innormal season are better than Shanyou 63, but stabilities of them areworse than Shanyou G3, (3 ) high temperatures of July and August inLuzhou arc main climate factors affecting milling quality of two-line hybrid ricegrain.
