水(shui)(shui)稻恶苗病(bing)(bing)是我区(qu)水(shui)(shui)稻上最(zui)主(zhu)要的种(zhong)(zhong)(zhong)(zhong)传病(bing)(bing)害，由区(qu)农技中(zhong)心(xin)抽样送检(jian)经(jing)市农技中(zhong)心(xin)检(jian)测(ce)，今年(nian)(nian)我区(qu)水(shui)(shui)稻主(zhu)要种(zhong)(zhong)(zhong)(zhong)植品种(zhong)(zhong)(zhong)(zhong)稻种(zhong)(zhong)(zhong)(zhong)恶苗病(bing)(bing)平均带菌(j꧑un)(jun)率(lv)为(wei)3.6%，最(zui)高8%，带菌(jun)(jun)率(lv)较去(qu)年(nian)(nian)略低(di)。但鉴于去(qu)年(nian)(nian)田间发病(bing)(bing)普遍，今年(nian)(nian)恶苗病(bing)(bing)仍存在较大(da)(da)流行风险。稻种(zhong)(zhong)(zhong)(zhong)药剂处理是控制水(shui)(shui)稻种(zhong)(zhong)(zhong)(zhong)传病(bing)(bing)害最(zui)经(jing)济有效的措(cuo)施，为(wei)此希望(wang)各街(jie)镇及广(guang)大(da)(da)种(zhong)(zhong)(zhong)(zhong)植户引起高度重视，认真做好水(shui)(shui)稻种(zhong)(zhong)(zhong)(zhong)子(zi)处理工(gong)作，为(wei)今年(nian)(nian)水(shui)(shui)稻高产(chan)丰收打下良好的基础。具体技术(shu)要求如下：
一、晒种选种
播前选晴好天(tian)气晒种(zhong)1～2天ꦬ(tian)，并精选种(zhong)子，除去秕粒病(bing)粒、减少菌源，以提高(gao)种(zhong)子的发芽(ya)势，增强秧苗(miao)抗(kang)病(bing♉)能力(li)。
二(er)、化剂加工(gong)消毒杀菌(jun)技能
1、处置方案：
每(mei)4kg稻(dao)(dao)种(zhong)(zhong)(zhong)(zhong)（亩(mu)用种(zhong)(zhong꧋)(zhong)(zhong)量）用浸种(zhong)(zhong)(zhong)(zhong)药剂9ml，采用二次稀释法(fa)，先加(jia)少量水(shui)调(diao)成浆糊(hu)状，然后(hou)再(zai)加(jia)清水(shui)6kg稀释，配(pei)成药液(ye)(ye)。将(jiang)选过(guo)的(de)稻(dao)(dao)种(zhong)(zhong)(zhong)(zhong)4kg（亩(mu)用种(zhong)(zhong)(zhong)(zhong)量）浸入配(pei)成的(de)药液(ye)(ye)中搅拌均匀，以药液(ye)(ye)高(gao)出种(zhong)(zhong)(zhong)(zhong)子2-3cm为宜。(若稻(dao)(dao)种(zhong)(zhong)(zhong)(zhong)数(s𒀰hu)量多可按上述相应比例配(pei)制)
2、浸(jin)种(zhong)时(shi)(shi)间：日(ri)平(ping)均(jun)气(qi)(qi)温低于20℃，浸(jin)种(zhong)时(shi)(shi)间应为60小(xiao)时(shi)(shi)，20℃以(yi)上(shang)，浸(jin)种(zhong)时(shi)(shi)间应在48小(xiao)时(shi)(shi)左(zuo)右，具体根据气(qi)(qi)温变(bian)化掌握好时(shi)(shi)间，但(dan)浸(jin)足时(shi)(sh👍i)间是(shi)保证药效的关键(jian)。
三、留意作用
1、浸种不(bu)锈钢容器(qi)要加盖，并(bing)放入通(tong)风背光处。严禁止蛇皮袋可以(yi)单独浸种，切不(bu)可危害结果。稻种杀菌消毒后(hou)不(bu)所(suo)需水冲冼，可可以(y♛🍸i)单独沥干(gan)催芽采收。
2、化学剂外理过的种子bt，勿(wu)与蛋白质🍒食物、祠🧔料贴到(dao)一切，应当喂养禽畜，更应当来(lai)用作(zuo)制(zhi)作(zuo)加(jia)工祠料或肉制(zhi)品。
3、服药(yao)后应制止药(yao)🌞液(ye)等马上排向(xiang)鱼(yu)池(chi)、虾塘等水(shui)产品(pin)养殖业的(de)敌方，制止造鱼(yu)、虾🐲、蟹死。
4、药剂封(feng)(feng)装废料物不宜随意扔掉或立(li)即(ji)救(jiu)治，有效交还各个药剂封(feng)(fe💦ng)装废料物环保再生资(zi)源回收点(dian)。
