水(shui)(shui)(shui)(shui)稻恶苗(miao)病是(shi)我区(qu)水(shui)(shui)(shui)(shui)稻上最(zui)主(zhu)(zhu)要的种(zhong)(zhong)(zhong)传病害(hai)，由区(qu)农(nong)技中心抽样送检(jian)经市农(nong)技中心检(jian)测，今年(nian)我区(qu)水(shui)(shui)(shui)(shui)稻主(zhu)(zhu)要种(zhong)(zhong)(zhong)植(zhi)品(pin)种(zhong)(zhong)(zhong)稻种(zhong)(zhong)(zhong)恶苗(miao)病平🍬均带菌率为(wei)(wei)3.6%，最(zui)高8%，带菌率较(jiao)去(qu)年(nian)略(lve)低。但(da🐈n)鉴于(yu)去(qu)年(nian)田间(jian)发病普遍，今年(nian)恶苗(miao)病仍存(cun)在较(jiao)大流(liu)行风险。稻种(zhong)(zhong)(zhong)药(yao)剂处理(li)是(shi)控(kong)制水(shui)(shui)(shui)(shui)稻种(zhong)(zhong)(zhong)传病害(hai)最(zui)经济有效(xiao)的措施(shi)，为(wei)(wei)此希望各(ge)街镇及(ji)广(guang)大种(zhong)(zhong)(zhong)植(zhi)户引(yin)起高度重视，认真做好(hao)水(shui)(shui)(shui)(shui)稻种(zhong)(zhong)(zhong)子处理(li)工(gong)作(zuo)，为(wei)(wei)今年(nian)水(shui)(shui)(shui)(shui)稻高产(chan)丰收打下(xia)良好(hao)的基础。具体技术要求如(ru)下(xia)：
一、晒种选种
播前选(xuan)晴好天气晒种(zhong)1～2天，并精选(xuan)种(zhong)子，除去秕(bi)粒病粒、减少(𝄹shao)菌源，以提高种(zh🌼ong)子的发芽势，增强(qiang)秧苗抗病能(neng)力。
二、解毒(du)药清(qing)理清(qing)洗能力
1、处置手段：
每(mei)4kg稻种(zhong)(zhong)（亩(mu)(mu)用(yong)(yong)种(zhong)(zhong)量(liang)(liang)）用(yong)(yong)浸种(zhong)(zhong)药剂9ml，采(cai)用(yong)(yong)二次稀释法，先加(jia)少量(liang)(liang)水调成(cheng)浆糊(hu)状，然后再加(jia)清水6kg稀释，配(pei)成(cheng)药液(ye)。将(jiang)选(xuan)过的稻种(zhong)(zhong)4kg（亩(mu)(mu)用(yong)(yong)种(zhong)(zhong)量(liang)(liang)）浸入配(pei)成(cheng)的药液(ye)中搅拌均(jun)匀(yun)，以药液(ye)高出种(zhong)(zhong)子(zi)2-3cm为宜。(若稻种(zhong)(zhong)数量(liang)(liang)多(duo)可按(an)上述相应(ying)比例🌳配(pei)制)
2、浸种(zhong)时(shi)间(jian)：日(ri)平均(jun)气温低(di)于20℃，浸种(zhong)时(shi)间(jian)应为60小(xiao)时(shi)，20℃꧋以上🅘(shang)，浸种(zhong)时(shi)间(jian)应在(zai)48小(xiao)时(shi)左右，具体(ti)根(gen)据气温变化掌握好时(shi)间(jian)，但浸足时(shi)间(jian)是保证药效的(de)关(guan)键(jian)。
三、重视事情
1、浸(jin)种溶器用加盖，并放置(zhi)到阴暗处(chu)背光(guang)处(chu)。严停止使用蛇皮袋随(sui)时(shi𒁃)浸(jin)种，否则的影(ying)响效果好。稻种杀(sha)菌后不想(xiang)要凉水冲冼(xꦫian)，可随(sui)时(shi)沥干催芽种植。
2、化(hua)学剂治(zhi)疗过的(de)种子选手(shou)，勿𝓀与粮食、预混料(liao)放入分着，不(bu)容(rong)许当(dang)喂料(li๊ao)禽(qin)畜，更不(bu)容(rong)许当(dang)把(ba)他们拿来(lai)生产(chan)预混料(liao)或产(chan)品。
3、治疗后应(ying)减少药液等真(zhen)接(j𒆙ie)倾倒垃圾(ji)鱼池(chi)、虾(xia)塘等水产养植养植的城市(shi)，减少产生鱼、虾(xia)🧔、蟹死掉(diao)。
4、除草剂标签印刷废品物(wu)禁止隨便丟弃或迅(xun)速处🔜里，迅(xun)速交给县级除草剂标签印刷废品物(wu)收购点。
