水(shui)(shui)稻(dao)(dao)恶(e)苗(miao)病(bing)(bing)是我区(qu)水(shui)(shui)稻(dao)(dao)上最(zui)(zui)主(zhu)要(yao)的(de)种(zhong)(zhong)(zhong)(zhong)(zhong)传(chuan)病(bing)(bing)害，由(you)区(qu)农技(ji)中(zhong)心抽样送检经市农技(ji)中(zhong)心检测(ce)，今年(nian)我区(qu)水(shui)(shui)稻(dao)(dao)主(zhu)要(yao)种(zhong)(zhong)(zhong)(zhong)(zhong)植品种(zhong)(zhong)(zhong)(zhong)(zhong)稻(dao)(dao)种(zhong)(zhong)(zhong)(zhong)(zhong)恶(e)苗(miao)病(bing)(bing)平均带菌率为(wei)(wei)3.6%，最(zui)(zui)高8%，带菌率较去年(nian)略低(di)。但鉴于去年(nian)田间发(fa)病(bing)(bing)普遍，今年(nian)恶(e)苗(miao)病(bing)(bing)仍存在较大流行风险(xian)。稻(dao)(dao)种(zhong)(zhong)(zhong)(zhong)(zhong)药剂处理(li)是控(kong)制水(shui)(shui)稻(dao)(dao)种(zhong)(zhong)(zhong)(zhong)(zhong)传(chuan)病(bing)(bing)害最(zui)(zui)经济有(you)效的(de)措施，为(wei)(wei)此希望各街镇及广大种(zhong)(zhong)(zhong)(zhong)(zhong)植户引起高度重视(shi)，认真(zhen)做好水(shui)(shui)稻(dao)(dao)种(zh💃ong)(zhong)(zhong)(zhong)(zhong)子处理(li)工作(zuo)，为(wei)(wei)今年(nian)水(shui)ও(shui)稻(dao)(dao)高产丰收打(da)下良(liang)好的(de)基(ji)础(chu)。具体(ti)技(ji)术要(yao)求如(ru)下：
一、晒种选种
播前选晴好天(tian)气晒种1～2天(tian)，并精(jing)选种子(zi)，除去秕粒病(bing)粒、减(jian)少(shao)菌源，以提高种子(zi)的发(fa🐬)芽势，增强秧苗抗病(bing)能力(li)。
二、中和剂清理灭(mie)菌技能
1、解决做法：
每4kg稻(dao)种(zhong)（亩(mu)用(yong)种(zhong)量(liang)）用(yong)浸种(zhong)药剂9ml，采用(yong)二次(ci)稀释(shi)法，先(xian)加少量(liang)水调成(cheng)🥂浆(jiang)糊状，然后(hou)再加清水6kg稀释(shi)，配(pei)成(cheng)药液。将选过的(de)稻(dao)种(zhong)4kg（亩(mu)用(yong)种(zhong)量(liang)）浸入(ru)配(pei)成(cheng)的(de)药液中搅拌均匀，𝓀以药液高出种(zhong)子2-3cm为宜。(若稻(dao)种(zhong)数量(liang)多可按上(shang)述(shu)相(xiang)应比(bi)例配(pei)制)
2、浸(jin)种(zhong)时(shi)(shi)间(jian)：日平均气温低(di)于20℃，浸(jin)种(zhong)时(shi)(shi)间(jian)应为ꦫ(wei)60小(xiao)时(shi)(shi)，20℃以上，浸(j✅in)种(zhong)时(shi)(shi)间(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)，但浸(jin)足(zu)时(shi)(shi)间(jian)是保证(zheng)药效(xiao)的(de)关(guan)键。
三、准备重大事项
1、浸种(zhong)(zhong)袋(dai)子要加盖(gai)，并至于阴凉处(chu)(chu)遮光处(chu)(chu)。严关闭蛇皮(pi)袋(dai)一直浸种(zhong)(zhong)，一旦影(ying)向成(cheng)果。稻(dao)ꦗ种(zhong)(zhong)空气消毒后(hou)不需用温开水冲冼，可一直沥干✤(gan)催芽采收。
2、药物(wu)制(zhi)剂(ji)正🦄(zheng)确(que)处理过的种子选手，勿与吃食(shi)、词料摆放在分着，不准喂食(shi)禽畜，更不准常做加工制ﷺ(zhi)作词料或食(shi)品厂。
3、用药(yao)量后(hou)应不(bu)要药(yao)液等(deng)(deng🍌)间接流进养鱼(yu)池、虾塘等(deng)(deng)海产养殖业的问(wen)题，൩不(bu)要产生(sheng)鱼(yu)、虾、蟹身亡。
4、农约进行设计𒉰(ji)废旧物(wu)(wu)不宜隨(sui)便(bian)扔掉或自愿处里(li)，适时归还县级农约进行设计(ji)废旧物(✃wu)(wu)收回点。
