水(shui)稻(dao)恶(e)苗病(bing)是我(wo)区(qu)(qu)水(shui)稻(dao)上最主要(yao)的种(zhong)(zhong)(zhong)(zhong)传病(bing)害，由区(qu)(qu)农技中心(xin)抽样送(song)检(jian)经市(shi)农技中心(xin)检(jian)测，今(jin)年(nian)我(wo)区(qu)(qu)水(shui)稻(d🐻ao)主要(yao)种(zhong)(zhong)(zhong)(zhong)植(zhi)品种(zhong)(zhong)(zhong)(zhong)稻(dao)种(zhong)(zhong)(zhong)(zhong)恶(e)苗病(bing)平均带菌(jun)(jun)率为3.6%，最高(gao)8%，带菌(jun)(jun)率较(jiao)去年(nian)略低。但鉴于去年(nian)田间(jian)发病(bing)普遍，今(jin)年(nian)恶(e)苗病(bing)仍存在较(jiao)大流行风险。稻(dao)种(zhong)(zhong)(zhong)(zhong)药剂处(chu)理是控制水(shui)稻(dao)种(zhong)(zhong)(zhong)(zhong)传病(bing)害最经济有效的措施，为此(ci)希望各街镇及广大种(zhong)(zhong)(zhong)(zhong)植(zhi)户引起(qi)高(gao)度重(zhong)视，认真做(zuo)好(hao)水(shui)稻(dao)种(zhong)(zhong)(zhong)(zhong)子处(chu)理工作，为今(jin)年(nian)水(shui)稻(dao)高(gao)产丰收打(da)下(xia)良(liang)好(hao)的基础。具(ju)体技术要(yao)求如(ru)下(xia)：
一、晒种选种
播前选晴好(hao)天气晒种(zhong)1～2天，并精(jing)选种(zhong)子꧙，除去秕粒病粒、减少菌源，以(yi)提(ti)高种(zhong)子的发芽势(shi)，增强秧苗抗(kang)病能力。
二、药物加工处(chu)理清洗(xi)能力
1、解决工艺：
每4kg稻种(zhong)(zhong)(zhong)（亩(mu)用种(zhong)(zhong)(zhong)量(liang)(lian🍃g)）用浸种(zhong)(zhong)(zhongไ)药剂(ji)9ml，采用二次(ci)稀释(shi)法，先加少(shao)量(liang)(liang)水(shui)调成浆(jiang)糊状，然后再加清(qing)水(shui)6kg稀释(shi)，配(pei)成药液(ye)。将选过的稻种(zhong)(zhong)(zhong)4kg（亩(mu)用种(zhong)(zhong)(zhong)量(liang)(liang)）浸入配(pei)成的药液(ye)中搅(jiao)拌(ban)均匀(yun)，以(yi)药液(ye)高出种(zhong)(zhong)(zhong)子2-3cm为宜。(若(ruo)稻种(zhong)(zhong)(zhong)数量(liang)(liang)多(duo)可按上述相应比例配(pei)制)
2、浸种(zhong)时(shi)(shi)间(jian)(jian)(jian)：日平均气(qi)温低于20℃，浸种(zhong)时(shi)(shi)间(♋jian)(jian)(jian)应(ying)为60小(xiao)时(shi)(shi)，20℃以上，浸种(zhong)时(shi)(shi♌)间(jian)(jian)(jian)应(ying)在48小(xiao)时(shi)(shi)左右，具体根据气(qi)温变化掌(zhang)握好时(shi)(shi)间(jian)(jian)(jian)，但浸足(zu)时(shi)(shi)间(jian)(jian)(jian)是保证(zheng)药(yao)效的(de)关键。
三、注重要点
1、浸种(zhong)贮槽都要加盖，并居于阴凉处(chu)阴凉处(chu)。严停止使用蛇皮袋间接(jie)浸种(zhong)，切勿(wu)导致成果(guo)。稻种(zhong)清洁后不(bu)都要⭕再𝔉用温水冲冼，可间接(jie)沥干催芽秋播。
2、的药剂治(zhi)理(li)ಌ过的种(zhong)子网，勿(wu)与美食、饲(si)草置于同(tong)🐬食，只能喂饲(si)禽畜(chu)，更只能用作粗加工饲(si)草或肉制(zhi)品。
3、联合用(yong)药(yao)后应防范药(yao)液等(deng)可以直排到养鱼池、虾塘等(deng)海产品养殖户的(de)方面，防🐭范导致鱼、虾、蟹阵亡(wang)。
4ও、药剂设计废物(wu)物(wu)严禁随心所欲(yu)丟弃(qi)或立刻正确处理(li)，即(ji)时归还各(ge)个药剂设计废物(wu)物(wu)再利用点��。
浸种药物制剂新品种等详请询问当地政府植物保护监管部门。
