水(shui)稻(dao)(dao)(dao)恶苗(miao)病是(shi)我区水(shui)稻(dao)(dao)(dao)上最主(zhu)要(yao)的种(zhong)(zhong)传病害，由区农技中心抽样送检(jian)经市农技中心检(jian)测，今年(nian)(nian)我区水(shui)稻(dao)(dao)(dao)主(zhu)要(yao)种(zhong)(zhong)植(zhi)(zhi)品种(zhong)(zho🌌ng)稻(dao)(dao)(dao)种(zhong)(zhong)恶苗(miao)病平均(jun)带(dai)菌(jun)率为3.6%，最高(gao)8%，带(dai)菌(jun)率较(jiao)去年(nian)(nian)略低。但鉴于去年(nian)(nian)田间发病普(pu)遍，今年(nian)(nian)恶苗(miao)病仍存在(zai)较(jiao)大(da)(da)流行风险。稻(dao)(dao)(dao)种(zhong)(zhong)药剂处(chu)理(li)是(shi)控制水(shui)稻(dao)(dao)(dao)种(zhong)(zhong)传病害最经济有效的措(cuo)施(shi)，为此希望各街镇及广(guang)大(da)(da)种(zhong)(zhong)植(zhi)(🍃zhi)户引起高(gao)度(du)重视(shi)，认(ren)真(zhen)做好(hao)水(shui)稻(dao)(dao)(dao)种(zhong)(zhong)子处(chu)理(li)工作(zuo)，为今年(nian)(nian)水(shui)稻(dao)(dao)(dao)高(gao)产(chan)丰(feng)收(shou)打下(xia)良(liang)好(hao)的基础。具(ju)体技术(shu)要(yao)求如(ru)下(xia)：
一、晒种选种
播(bo)前选晴好天(tian)气(qi)晒种1～2天(tian)，并精选种子，除去(qu)秕粒病粒、减少(shao)菌源𒉰(yua🐟n)，以(yi)提高种子的发(fa)芽势(shi)，增强秧苗抗病能力。
二、化(hua)学(xue)剂治疗空气消毒高技术(shu)
1、办理技术：
每4kg稻种(zhong)(zhong)(zhong)(zhong)（亩用(yong)种(zhong)(zhong)(zhong)(zhong)量）用(yong)浸种(zhong)(zhong)(zhong)(zhong)药(yao)剂9ml，采用(yong)二(er)次稀(xi)释法(fa)，先加少量水调成浆(jiang)糊状(zhuang)，然后再加清水6kg稀(xi)释，配(pei)(pei)成药(yao)液(ye)。将选(xuan)过的稻种(zhong)(zhong)(zhong)(zhong)4kg（🦩亩用(yong)种(zhong)(zhong)(zhong)(zhong)量）浸入配(pei)(pei)成的药(yao)液(ye)中搅拌均匀，以(yi)药(yao)液(ye)高出种(zhong)(zhong)(zhong)(zhong)子2-3cm为宜(yi)。(若⛎稻种(zhong)(zhong)(zhong)(zhong)数量多可按(an)上(shang)述相应(ying)比例配(pei)(pei)制)
2、浸种(zhong)时(shi)(shi)(shi)(shi)间：日平均气温(wen)低(di)于20℃，浸种🏅(zhong)时(shi)(shi)(shi)(shi)间应为60小时(shi)(shi)(shi)(shi)，20℃以上(shang)，浸种(zhong)时(shi)(shi)(shi)(shi)间应在48小时(shi)(shi)(shi)(shi)左右，具(ju)体根据气温(wen)变(bian)化掌握(wo)好时(shi)(shi)(shi)(shi)间，但浸足时(shi)(shi)(shi)(shi)间是保(bao)证药效的关键。
三、注意项目项目
1、浸(jin)(jin)种储罐还(hai)(hai)要盖，并(bing)放在阴凉处背光处꧟。严不(bu)可(ke)用蛇(she)皮(piꦺ)袋立即浸(jin)(jin)种，否则(ze)关系效率。稻(dao)种杀菌(jun)后不(bu)还(hai)(hai)要盐水冲冼，可(ke)立即沥(li)干催芽(ya)秋播。
2、中和剂解决过的原材料，勿与吃的东(dong)西、饲草置于同时，严禁(jin)当喂料禽畜，更严禁(jin)当来用ꦡ作工(gong)艺饲草ꦫ或食品加工(gong)。
3、服药后(hou)应应对药液等(deng)随(sꦺui)便(bian)排放养鱼池、虾塘等(deng)海产品饲养的点，应对有(you)鱼、虾、蟹致死。
4、除草剂(🎐ji)杀菌(jun)剂(ji)标签(qian)印(yin)刷废品(pin)物不(bu)得(de)已隨意丢去(qu)或自(zi)愿防(fang)范，直接交还各项除草剂(ji)杀菌(jun)剂(ji)标签(qian𒐪)印(yin)刷废品(pin)物回报点。
