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。
Preliminary studies were conducted on the occurrence and regularity of major pests and diseases under five cultivation methods, including no-tilling and throwing cultivation in dry land, seedling machine inserted in the same plant, no-tilling and throwing cultivation in the field, no-tillage and sowing in the oil forest and conventional planting. The results showed that no-tillage intercropping of oil plantation could inhibit the occurrence of seedling blast and leaf blast in rice plantation. The five cultivation methods had some effects on the occurrence of panicle blast and sheath blight, but had no effect on the occurrence of rice false smut. The occurrence of Chilo suppressalis occurred slightly in the insertion-partial method, and there was no significant difference among the other four methods.
