摘　　要：以7个中国品种和7个日本品种为材料,分析施用米糠与杂草和穗颈稻瘟病发生的关系,为水稻有机栽培提供必要的理论依据。结果表明,发生杂草的种类以鸭舌草为主,占杂草种类的78%～99%,稗草的发生量从试验开始占全部杂草的20%,逐渐减少,试验第3年没有发生。穗颈稻瘟病发生,依据年次变化稍有不同,几乎所有年度、所有的品种都是有机栽培区比普通栽培区发病率低。从产量角度考虑,穗颈稻瘟病大量发生的年份,所有品种的平均产量明显降低。The experiment was conducted to study the effects of rice bran application after transplanting on weed and the first spike of rice blast with 7 Chinese cuhivars and 7 Japanese cultivars. The results showed that, the type of weeds was given priority to sheathed monochoria, accounting for 78% - 99% of weed species. The barnyardgrass quantity from the initial test accounted for 20% of all weeds, and gradually reduced, it did not happen on the third year trial. The first spike of rice blast was slightly different in four years. The incidence was lower in organic cultiva- tion area than ordinary cultivation area for all varieties in all years. The average yield decreased significantly for all varieties when the first spike of rice blast was happened severely. It showed that the first spike of rice blast influ- enced on yields obviously.
