水(shui)(shui)稻(dao)(dao)恶苗(miao)病(bing)是我区(qu)水(shui)(shui)稻(dao)(dao)上(shang)最主要的种(zhong)(zhong)传病(bing)害，由区(qu)农(nong)技(ji)中心抽(chou)样送(song)检经市农(nong)技(ji)中心检测(ce)，今年(nian)我区(qu)水(shui)(shui)稻(dao)(dao)主要种(zhong)(zhong)植品种(zhong)(zhong)稻(dao)(dao)种(zhong)(zhong)恶苗(miao)病(bing)平(ping)均带(dai)菌率为3.6%，最高(gao)8%，带(dai)菌率较(jiao)去年(nian)略低。但(dan)鉴于去年(nian)田间发病(bing)普遍，今年(nian)恶苗(miao)病(bing)仍存在较(jiao)大流(liu)行(xing)风险。稻(dao)(dao)种(zhong)(zhong)药剂处(chu)(chu)理(li)是控制水(shui)(shui)稻ᩚᩚᩚᩚᩚᩚᩚᩚᩚ𒀱ᩚᩚᩚ(dao)(dao)种(zhong)(zhong)传病(bing)害最经济有(you)效(xiao)的措施，为此(ci)希望各(ge)街镇及广大种(zhong)(zhong)植户引起高(gao)度重(zhong)视，认真做好水(shui)(shui)稻(dao)(dao)种(zhong)(zhong)子(zi)处(chu)(chu)理(li)工作(zuo)，为今年(nian)水(shui)(shui)稻(dao)(dao)高(gao)产丰(feng)收打下(xia)良好的基础。具体技(ji)术要求如下(xia)：
一、晒种选种
播前选晴好天(tian)(tian)气晒(shai)种(zhong)1～2天(tian)(tian)，并精选种(zhong)子(zi)，除(chu)去秕粒病粒、减少(sha🎀𓆉o)菌源(yuan)，以提高种(zhong)子(zi)的发芽(ya)势，增强秧苗抗病能(neng)力。
二、药品正确处理消毒杀菌枝术
1、外理的方法：
每4kg稻种(zhong)(zhong)（亩用(yong)种(zhong)(zhong)量(liang)(liang)）用(yong)浸种(zhong)(zhong)药(yao)剂9ml，采用(yong)二次稀(xi)(xi)释(shi)法，先加少量(liang)(liang)水调(diao)成(cheng)浆糊(hu)状(zhuang)，然(ran)后(hou)再加清水6kg稀(xi)(xi)释(shi)，配成(cheng)药(yao)液。将选过(guo)的稻种(zhong)(zhong)4kg（亩用(yong)种(zhong)(zhong)量(liang)(liang)）浸入配成(cheng)的药(yao)液中搅拌෴均匀，以(yi)药(yao)液高出种(zhong)(zhong)子2-3cm为(wei)宜。(若稻种(zhong)(zhong)数量(liang)(liang)多可按上述相应(ying)比例配制)
2、浸种时(shi)(shi)间(jian)(jian)：日平均气温低于(yu)20℃，浸种时(shi)(shi)间(jian)(jian)应为60小💯(xiao)时(shi)(shi)，20℃以上(shang)，浸种时(shi)(shi)间(jian)(jian)应在48小(xiao)时(shi)(shi)左右，具体(ti)根据气温变化掌握(wo)好时(shi)(shi)间(jian)(jian)，但浸足时(shi)(shi)间(jian)(jian)是保证(zheng)药效的(de)关(guan)键。
三、留意法定程序
1、浸(jin)种(zhong)(zhong)贮(zhu)槽用加盖，并(bing)放(fang)置背阴背光处。严(yan)阻止蛇皮袋同(tong)时浸(jin)种(zhong)(zhong)，防(fang)止不(bu)良影响使用效(xiao)果。稻(dao)种(zhong)(zhong)空🔥气消毒后不(bu)须得凉水冲冼(xian🌞)，可同(tong)时沥干催芽插种(zhong)(zhong)。
2、药(yao)水(shui)生产(chan🐓)处理过的(de)種子(zi)，勿与吃物、饲料添(tian)(tian)(tian)加剂(ji)(ji)添(tian)(tian)(tian)加剂(ji)(ji)放(fang)一(yi)件，不(bu)许(xu)已喂饲禽(qin)畜，更不(bu)许(xu)已可以生产(chan)饲料添(tian)(tian)(tian)加剂(ji)(ji)添(tian)(tian)🌜(tian)加剂(ji)(ji)或面制品。
3、用药量(liang)后应杜绝药液等一直直排(pai)渔(yu)♑塘(tang)、虾塘(tang)等海产(chan)农(nong)村养殖(zhi)的部分(fen)，杜绝引起鱼、虾、蟹消亡。
4、药剂封(feng)装废品(pin)物应当肆意丟掉或自(zi)己(ji)处治，即(ji)时(shi)归还各项药剂封(feng)装废品(🥂pi𒁏n)物的(de)回(hui)收利用点。
