稻瘟病规范化防治技术应用及其效益

 稻瘟病(Pyricularia oryzae Cav.)在水稻生长发育过程中都可发生危害,成为阻碍水稻生产发展的突出问题.每年道真都有4000～5000hm²水稻发生严重稻瘟病,靠单一的技术难以压控稻瘟病的危害.通过采取综合防治措施,实施规范化防治技术是控制稻瘟病危害的有效途径.笔者于1995～1997年,经3年示范推广工作,取得显着成效.

Application and Benefits from the Standardizing Control Technique Against Rice Blast

Rice blast (Pyricularia oryzae Cav.) could occur throughout rice growth period, and become a major problem in rice production. In our county, there are about 4 000 to 5 000 hm 2 of rice suffered severely from the disease every year. While single technique hardly works in the conrtol of the disease, a set of standardizing integrated techniques works very well. From 1995 to 1997, I had engaged in extension the effective technique, and got a satisfied result. Here is the reports.
