水(shui)稻(dao)恶(e)苗(miao)病(bing)(bing)是我区(qu)水(shui)稻(dao)上最(zui)主要(yao)的种(zhong)(zhong)(zhong)传病(bing)(bing)害，由区(qu)农技中(zhong)心(xin)(xin)抽(chou)样送检经市农技中(zhong)心(xin)(xin)检测，今年(nian)我区(qu)水(shui)稻(dao)主要(yao)种(zhong)(zhong)(zhong)植(zhi)品(pin)种(zhong)(zhong)(zhong)稻൲(dao)种(zhong)(zhong)(zhong)恶(e)苗(miao)病(bing)(bing)平均带(dai)菌(jun)(jun)率为(wei)3.6%，最(zui)高8%，带(dai)菌(jun)(jun)率较(jiao)去(qu)(qu)年(nian)略低。但鉴于去(qu)(qu)年(nian)田间发病(bing)(bing)普遍，今年(nian)恶(e)苗(miao)病(bing)(bing)仍(reng)存在较(jiao)大(da)流行风险(xian)。稻(dao)种(zhong)(zhong)(zhong)药剂处(chu)理(li)是控(kong)制水(shui)稻(dao)种(zhong)(zhong)(zhong)传病(bing)(bing)害最(zui)经济有效的措施，为(wei)此(ci)希望各街镇及广大(da)种(zhong)(zhong)(zhong)植(zhi)户(hu)引起高度重视，认真做好水(shui)稻(dao)种(zhong)(zhong)(zhong)子处(chu)理(li)工作，为(wei)今年(nian)水(shui)稻(dao)高产(chan)丰收打下良好的基础。具体技术(shu)要(yao)求如下：
一、晒种选种
播前(qian)选晴好天(tian)(tian)气晒种(zhong)1～2天(tian)(tian)，并精选种(zhong)子，除(chu)去(qu)秕粒病(bing)粒、减少🦋菌源，以提高(gao)种(zhong)子的发芽势(shi)，增强秧苗抗病(bing)能力(li)。
二、化剂(ji)进行处理消毒液技术设备
1、办理的办法：
每4kg稻(dao)种(zhong)(zhong)（亩(mu)用(yong)(yong)(yong)种(zhong)(zhong)量(liang)）用(yong)(yong)(yong)浸种(zhong)(zhong)药(yao)(yao)(yao)剂9ml，采(cai)用(yong)(yong)(yong)二次稀(xi)释法，先加(jia)少(shao)量(liang)水(shui)调成(cheng)(cheng)(cheng)浆糊(hu)状，然(ran)后再加(jia)清水(shui)6kg稀(xi)释，配(pei)成(cheng)(cheng)(cheng)药(yao)(yao)(yao)液。将选过(guo)的稻(dao)种(zhong)(zhong)4kg（亩(mu)用(yong)(yong)(yong)种(zhong)(zhong)量(liang)）浸入配(pei)成(cheng)(cheng)(cheng)的药(yao)(yao)(y🔯ao)液中(zhong)搅(jiao)拌均匀(yun)，以(yi)药(yao)(yao)(yao)液高(gao)出种(zhong)(zhong)子2-3cm为宜。(若稻(dao)种(zhong)(zhong)数(shu)量(liang)多(duo)可按上述相(xiang)应比例配(pei)制)
2、浸(jin)(jin)种(zhong)时间(jian)：日平(ping)均气(qi)温(wen)(wen)低于20℃，浸(jin)(jin)种(zhong)时间(jian)应(ying)为60小时，20℃以上(shang)，浸(jin)(jin)𓆏种(zhong)时间(jian)应(ying)在48小时左(zuo)右，具体根据气(qi)温(wen)(wen)变化掌握好时间(jian)，但浸(jin)(jin)足时间(jian)是保证药效的(de)关键。
三、特别注意事情
1、浸种💜(zhong)储罐(guan)都要(yao)盖，并放入(ru)背阴闭光处。严停止使(shi)用蛇皮袋直观(guan)浸种(zhong)，防止影(ying)响力(li)的效(xiao)果(guo)。稻种(zhong)消毒(du)杀菌后不都要(yao)冷水(shui)冲冼，可直观(guan)沥干催芽种(zhong)植。
2、药物制剂进行处理(li)过(guo)的种子吧，勿与(yu)吃的食物、饲草(cao)(cao)贴到一同，不许喂养禽♓畜，更不许常做处理(li)饲草(cao)(cao)或物品。
3、用药(yao)量后应防范药(yao)液等真接排放到(dao)渔塘(tang)、虾塘(tang)等鱼(y🅘u)业养值的特点，防范容易(yi)造成鱼(yu)、虾、蟹阵亡。
4、化(hua)肥(fei)木箱废料物不得当(dang)随时扔掉(diao)或擅自妥善处理，即时归还各(g🐓e)个化(hua)肥(fei)木箱废料物再利用点(dian)。
浸种药物制剂类种等详请询问地方值保部位。
