在良种繁育基地进行水稻种子繁育时,最有效的条件之一,是在最适宜的环境中集中进行种子专业化生产。通常,应当按照水稻生态学的要求,对具体繁种地点进行专门考查,最后提出科学论据。按有效积温条件,乌兹别克斯坦水稻栽培分别分布在以下三个地区:第一是塔什干、锡尔河流域、花勒子模地区和费尔干纳盆地(有效积温变动范围是2145～2482℃);第二是卡拉卡尔巴克共和
One of the most effective conditions for rice seed breeding at the breeding base is to focus specialized seed production in the most suitable environment. Normally, specific sites for species breeding should be specially examined according to the requirements of rice ecology, and finally scientific arguments should be put forward. According to the effective accumulated temperature condition, Uzbekistan rice cultivation is distributed in the following three regions respectively: the first is Tashkent, Syria River Basin, Huarenzi Mode and Fergana Basin (the effective accumulated temperature varies from 2145 to 2482 ℃); The second is Karakul Bak Republic
