黑龙江省绥化市北林区是粮食生产大县之一,水稻是北林区的主栽作物,每年种植面积100万亩左右,在我区粮食生产和经济发展中起着至关重要的作用。随着水稻耕作制度、耕作模式的演变及水稻品种的变化,以及气候条件的变化,近几年以来水稻二化螟在我区发生,且逐渐上升为水稻上危害较大的虫害,呈逐年扩大加重发生的趋势,该虫害的发生对水稻生产安全构成了极大的威胁,已成为水稻病虫害防治的焦点话题和水稻生产潜在的危险。为此,我们针对水稻二化螟的发生规律与防治措施进行了大量的研究工作,总结出了水稻二化螟的发生规律与防治措施,以供农民在生产实践中应用。
Beilin District, Suihua City, Heilongjiang Province, is one of the major food production counties. Rice is the main crop in Beilin District. The annual planting area is about 1 million mu. It plays a crucial role in grain production and economic development in our region. With the rice farming system, the evolution of farming patterns and changes in rice varieties, as well as changes in climatic conditions, rice stem borer occurred in our district in recent years, and gradually increased to rice pests damage larger, was gradually expanded Aggravating the trend of occurrence. The occurrence of pests posed a great threat to the safety of rice production, which has become the focus of rice pest control and the potential danger of rice production. Therefore, we conducted a lot of research work on the occurrence and control measures of rice stem borer, summed up the occurrence of rice stem borer and control measures for farmers in production practice.
