水(shui)稻(dao)(dao)(dao)恶(e)(e)苗病(bing)(bing)是(shi)我(wo)区(qu)(qu)水(shui)稻(dao)(dao)(dao)上(shang)最(zui)(zui)主(zhu)要(yao)的种(zhong)(zhong)(zhong)(zhong)传病(bing)(bing)害，由区(qu)(qu)农技(ji)中心抽样(yang)送(song)检(jian)经(jing)市农技(ji)中心检(jian)测(ce)，今年我(wo)区(qu)(qu)水(shui)稻(dao)(dao෴)(dao)主(zhu)要(yao)种(zhong)(zhong)(zhong)(zhong)植品种(zhong)(zhong)(zhong)(zhong)稻(dao)(dao)(dao)种(zhong)(zhong)(zhong)(zhong)恶(e)(e)苗病(bing)(bing)平均带菌率(lv)为(wei)3.6%，最(zui)(zui)高8%，带菌率(lv)较去年略低。但鉴于去年田间(jian)发病(bing)(bing)普遍，今年恶(e)(e)苗病(bing)(bing)仍存(cun)在(zai)较大(da)流行风险。稻(dao)(dao)(dao)种(zhong)(zhong)(zhong)(zhong)药(yao)剂处理是(shi)控制(zhi)水(shui)稻(dao)(dao)(dao)种(zhong)(zhong)(zhong)(zhong)传病(bing)(bing)害最(zui)(zui)经(jing)济有效的措(cuo)施(shi)，为(wei)此希(xi)望各街镇及广大(da)种(zhong)(zhong)(zhong)(zhong)植户引(yin)起高度重视，认真做好水(shui)稻(dao)(dao)(dao)种(zhong)(zhong)(zhong)(zhong)子处理工作(zuo)，为(wei)今年水(shui)稻(dao)(dao)(dao)高产丰收打下(xia)良(liang)好的基础(chu)。具体(ti)技(ji)术要(yao)求如下(xia)：
一、晒种选种
播前选晴(qing)好(hao)天(tian)气♒晒种(zhong)1～2天(tian)，并精选种(zhong)子，除去秕粒病粒、减(jian)少菌源，以提高种(zhong)子的发芽势(shi)，增强秧苗(miao)抗病能力。
二、药品除理杀菌消毒技(ji)术性(xing)
1、进行处理技术：
每4kg稻(dao)种(zh𒉰ong)（亩用种(zhong)量(liang)）用浸种(zhong)药剂(ji)9ml，采用二次稀释(shi)(shi)法，先加少量(liang)水调(diao)成浆糊状，然后再(zai)加清水6kg稀释(shi)(shi)，配成药液(ye)。将选过(guo)的稻(dao)种(zhong)4kg（亩用种(zhong)量(liang)）浸入配成的药液(ye)中(zhong)搅拌均匀，以药液(ye)高出种(zhong)子2-3cm为宜。(若(ruo)稻(dao)种(zhong)数量(liang)多可按上述相应比例配制)
2、浸(jin)种(zhong)(zhong)时(shi)(shi)间：日平均气温低于20℃，浸(jin)种(zhong)(zhong)时(shജi)(shi)间应为60小时(shi)(shi)，20℃以上，浸(jin)💃种(zhong)(zhong)时(shi)(shi)间应在48小时(shi)(shi)左右，具体根据气温变(bian)化掌(zhang)握好时(shi)(shi)间，但(dan)浸(jin)足时(shi)(shi)间是保证药效(xiao)的关键。
三、目光装修细节
1、浸种(zhong)玻(bo)璃(✤li)容器要(yao)加盖，并放入荫凉背光处。严(yan)禁止使(shi)用蛇皮袋(dai)单(dan)独(du)(du)浸种(𓂃zhong)，一(yi)旦不(bu)(bu)良影响体(ti)验。稻种(zhong)消毒杀菌后(hou)不(bu)(bu)想要(yao)温(wen)开(kai)水冲冼，可(ke)单(dan)独(du)(du)沥(li)干(gan)催芽下种(zhong)。
2、化(hua)学剂办理过的种子吧，勿与吃的东西、精饲(si)(si)料(liao)厂摆放(fang)在(zai)在(zai)一起，禁止🐽(zh🌞i)喂养(yang)禽畜(chu)，更禁止(zhi)把他们拿来工作精饲(si)(si)料(liao)厂或食材。
3、口服药(yao)物后应(ying)减少药(yao)液等就直(zhi)接排向鱼池、虾塘等海产养殖厂的部(bu)位，减少诱发鱼、虾、蟹突然(ran)死(si)亡(wang💟)。
4、农约设计废品物不恰简单🌃抛弃或立即治理，实时交(jiao)给(ji)各个(ge)等级农约设计废品物收(shou)购(gou) 点。
