水稻(dao)恶苗(miao)病(bing)是我区(qu)(qu)水稻(dao)上最主要(yao)(yao)的种(zhong)(zhong)(zhong)(zhong)传病(bing)害，由区(qu)(qu)农(nong)(nong)技中(zhong)心抽(chou)样(yang)送检(jian)经市农(nong)(nong)技中(zhong)心检(jian)测，今年我区(qu)(qu)水稻(dao)主要(yao)(yao)种(zhong)(zhong)(zhong)(zhong)植品(pin)种(zhong)(zhong)(zhong)(zhong)稻(dao)种(zhong)(zhong)(zhong)(zhong)恶苗(miao)病(bing)平(ping)均带菌率(lv)为3.6%，最高(gao)8%，带菌率(lv)较去(qu)年略低。但鉴于去(qu)年田间发病(bing)普遍，今年恶苗(miao)病(bing)仍存在较大(da)流(liu)行(xing)风险。稻(dao)种(zhong)(zhong)(zhong)(zhong)药(yao)剂(ji)处理是控制(zhi)水稻(dao)种(zhong)(zhong)(zhong)(zhong)传病(bing)害最经济(ji)有效的措施(shi)，为此希望各(ge)街镇𝐆及(ji)广大(da)种(zhong)(zhong)(zhong)(zhong)植户引起高(gao)度重视，认真做好水稻(dao)种(zhong)(zhong)(zhong)(zhong)子处理工(gong)作，为今年水稻(dao)高(gao)产丰收打下良好的基础。具体技术要(yao)(yao)求如下：
一、晒种选种
播前(qian)选(xuan)晴好(hao)天(tian)(tian)气晒(shai)种1～2天(tian)(tian)，并(bing)精(jing)选(xuan)种子(zi)，除(chu)去秕粒病粒、减少(shao)菌ꦡ(jun)源，以提(ti)高种子(zi)的发芽势，增强秧𝕴苗抗病能力。
二、中和(he)剂正确处理(li)灭菌技术应用
1、操作方式：
每4kg稻(dao)(dao)种(zhong)(zhong)(zhong)（亩(mu)用种(zhong)(zhong)(zhong)量）用浸种(zhong)(zhong)(zhong)药剂(ji)9ml，采用二次稀释法，先加少量水调成浆糊状(zhuang)，然后再加清水6kg稀释，配(pei)成药液(ye)。将选(xua✅n)过的稻(dao)(dao)种(zhong)(zhong)(zhong)4kg（亩(mu)用种(zhong)(zhong)(zhong)量）浸入(ru)配(pei)成的药液(ye)中搅(jiao)拌均(jun)匀，以药液(ye)高出种(zhong)(zhong)(zhong)子2-3cm为宜。(若稻(dao)(dao)种(zhong)(zhong)(zhong)数量多可按(an)上述相(xiang)应比(bi)例配(pei)制(zhi))
2、浸种(zh﷽ong)时(shi)(shi)间(jian)(jian)：日平均气温低于20℃，浸种(zhong)时(shi)(shi)间(jian)(jian)应为(wei)60小时(shi)(shi)，20℃以上，浸种(zhong)时(shi)(shi)间(jian)(jian)应在48小时(shi)(shi)左💛右，具体根据气温变化(hua)掌握(wo)好时(shi)(shi)间(jian)(jian)，但浸足时(shi)(shi)间(jian)(jian)是保证(zheng)药效的关键。
三、考虑要点
1、浸种(zhong)场所必(bi)须要加盖，并置放背阴(yin)闭光处。严禁止蛇皮(pi)袋同(tong)(tong)时浸种(zhong)，切不(bu)可(ke)不(bu)良影(ying)响成(cheng)果。稻种(zhong)清洁后不(bu)必(bi)须要池(chi)水冲冼，可(ke)同(tong)🌜(tong)时沥干催芽栽种(zhong)。
2、的药剂整🦋理过(guo)的种子视频下载，勿与饮食、饲草在一(yi)块，不可(ke)喂饲禽畜，更(geng)不可(ke)用做工作饲草或✤饮食。
3、治疗后应(yi🐼ng)应(ying)对药(yao)液等真接(jie)排进(jin)水塘、虾塘等水产业(ye)养值(zhi)的地方，应(yin༒g)对出现(xian)鱼、虾、蟹消失。
4、除(chu)草剂内(nei)包装(z🍷huang)(zhuang)盒废置物允许擅自放(fang)弃或立刻加工，适时(shi)归还各部(bu)除(chu)草剂内(nei)包装(zhuang)(zhuang)盒废置物收集点(dian)。
