摘要
对旱育免耕抛栽、小苗机插、盘育免耕抛栽、油林免耕套播、常规栽插等5种栽培方式下水稻主要病虫害的发生程度与规律进行了初步研究。结果表明:油林免耕套播可抑制水稻苗瘟和叶瘟的发生,5种栽培方式对穗颈瘟和纹枯病的发生程度有一定影响,对稻曲病的发生没有影响;小苗机插偏方式下二化螟的发生较轻,其它4种方式之间发生程度没有显著差异。
The preliminary studies were carried out on the incidence of major diseases and insect pests under five rice cultivation models, namely, broadcasted dry-raising rice seeding no-tillage, mechanical planting, broadcasted plate breeding no-tillage, rape-rice no-tillage interplanting and customary planting. The results showed that the cultivation model of rape-rice no-tillage interplanting was not conducive to rice seedling and leaf blast occurrence;the occurrence of rice sheath blight and rice panicle blast on five cultivation models had a certain degree of difference, but that of rice false smut had no difference. Except the slight occurrence of stem borer of rice with the mechanical planting, the other four models showed not significant difference.
