摘要

摸清南方水稻黑条矮缩病病原越冬情况,为南方水稻黑条矮缩病的预测预报和综合治理提供科学依据。2013年3—4月采用普查和抽查相结合的方法,对地处广东省西南部的化州市南方水稻黑条矮缩病病原越冬情况进行调查和研究。结果表明:化州市存在大面积、高密度的南方水稻黑条矮缩病越冬区域,越冬面积0.37万hm2,平均病丛率13.3%,最高达68.3%。初步分析出该年度再生稻发生南方水稻黑条矮缩病与气候条件和上年田间病毒源有关。明确了南方水稻黑条矮缩病在化州地区冬季再生稻可顺利越冬,研究结果可为南方水稻黑条矮缩病的有效防治提供技术支撑。

Abstract

Ascertain the southern rice black-streaked dwarf virus overwintering conditions, which is conducive to provide scientific basis of the prediction and comprehensive management for the rice. In this paper, the author carried out census and spot check combination method to study the SRBSDV overwintering in Huazhou, Guangdong Province from March to April in 2013. The results illustrated that, there was a large and high-density overwintering area about 0.37 hm2 in Huazhou, and the average diseased bundle rate was 13.3% while the highest was up to 68.3%. This paper also showed that, the SRBSDV occurrence of the ratooning rice was related to the climate condition and the previous year field virus source. It confirmed that the SRBSDV could overwintering successfully while parasitizing winter ratoon rice in Huazhou, which provided technical support for the SRBSDV prevention.
