水(shui)(shui)稻(dao)(dao)(dao)(dao)恶苗病(bing)是我区水(shui)(shui)稻(dao)(dao)(dao)(dao)上(shang)最(zui)主(zhu)要的(de)种(zhong)(zhong)(zhong)传病(bing)害,由▨区农技(ji)(ji)中(zhong)心抽样送检经市农技(ji)(ji)中(zhong)心检测,今年我区水(shui)(shui)稻(dao)(dao)(dao)(dao)主(zhu)要种(zhong)(zhong)(zhong)植(zhi)品种(zhong)(zhong)(zhong)稻(dao)(dao)(dao)(dao)种(zhong)(zhong)(zhong)恶苗病(bing)平均(jun)带菌率为3.6%,最(zui)高(gao)8%,带菌率较(jiao)去年略(lve)低。但鉴于去年田间发病(bing)普(pu)遍,今年恶苗病(bing)仍存在(zai)较(jiao)大(da)流(liu)行风险。稻(dao)(dao)(dao)(dao)种(zhong)(zhong)(zhong)药剂处理是控制水(shui)(shui)稻(dao)(dao)(dao)(dao)种(zhong)(zhong)(zhong)传病(bing)害最(zui)经济(ji)有效的(de)措施,为此希(xi)望各街镇(zhen)及广大(da)种(zhong)(zhong)(zhong)植(zhi)户(hu)引(yin)起高(gao)度重视(shi),认真做好水(shui)(shui)稻(dao)(dao)(dao)(dao)种(zhong)(zhong)(zhong)子处理工作(zuo),为今年水(shui)(shui)稻(dao)(dao)(dao)(dao)高(gao)产丰收打下良好的(de)基础。具体技(ji)(ji)术要求如下:

一、晒种选种

播前选(xuan)晴好天气(qi)晒种(zhongꦺ)1~2天,并精(jing)选(xuan)种(zhongꦍ)子,除去(qu)秕(bi)粒病(bing)粒、减少菌源,以提(ti)高种(zhong)子的发芽势,增强(qiang)秧苗(miao)抗病(bing)能(neng)力(li)。

二(er)、药液(ye)处置(zhi)消毒剂能力

1、除理方式方法:

每4kg稻(dao)种(zhong)(zhong)(zhong)(亩用(yong)种(zhong)(zhong)(zhong)量(liang))用(yong)浸种(zhong)(zhong)(zhong)药(yao)剂9ml,采用(yong)二(er)次稀(xi)释(shi)法,先加(jia)少量(liang)水调成(cheng)浆糊状,然后(hou)再加(jia)清水6kg稀(xi)释(shi),配(pei)成(cheng)药(yao)液。将选(xuan)过的稻(dao)种(zhong)(zhong)(zhong)4kg(亩用(yong)种(zhong)(zhong)(zhong)量(liang))浸入配(pei)成(cheng)的药(yao)液中搅拌均匀,以药(yao)液高(gao)出种(zhong)(zhong)(zhong)子2-3cm为宜。(若(ruo)稻(dao)种(zhong)(zhong)(zhong)数(shu)量(liang)多可(ke🐈)按上述相应比例配(pei)制)

2、浸(jin)种(zhong)(zhong)时(shi)(shi)(shi)间(jian):日平(ping)均气温(wen)低于20℃,浸(jin)种(zhong)(zhong)时(shi)(shi)(shi)间(jiaꦅn)应(ying)为(wei)60小时(shi)(shi)(shi),20℃以上,浸(jin)种(zhong)(zhong)时(shi)(shi)(shi)间(jian)应(ying)在48小时(shi)(shi)(shi)左右,具体根据气温(wen)变化掌握好时(shi)(shi)(shi)间(jian),但浸(jin)足时(shi)(shi)(sꦑhi)间(jian)是保(bao)证药效的(de)关键。

三、要留意法定程序

1、浸(jin)(jin)种(zhong)干(ga🉐n)(gan)净(jing)的(de)器(qi)皿想(xiang)要(yao)盖,并放入通风遮光处。严不(bu)(bu)可用蛇皮袋(dai)随(sui)便浸(jin)(jin)种(zhong),进而作用目的(de)。稻种(zhong)杀菌消(xiao)毒后不(bu)(bu)想(xiang)要(yao)白水(shui)冲冼(xian),可随(sui)便沥(li)干(gan)(gan)催芽载种(zhong)。

2、的(de)药剂(ji)除理过的(de)种子吧,勿(wu)与粮(liang)食、词(ci)料在(zai)混着,不(bu)容许喂(wei)饲(si)禽畜(chu),更不(bu)容许用(yong)到代𓆏加工词(ci)料或食品原(yuan)料。

3、用药(yao)指导后(hou)应🥂预防(fang)药(yao)液等真接(jie)污(wu)水(shui)(shui)排放水(shui)(shu🔜i)塘、虾塘等渔业家庭(ting)养殖的部位,预防(fang)从而造成鱼、虾、蟹死忙。

4、除草剂纸𓆏(zhi)盒进行🔴包(bao)装放弃物严禁随时放弃或自动应急处置,有效(xiao)交给各(ge)级党委(wei)除草剂纸(zhi)盒进行包(bao)装放弃物回(hui)笼点。
