水(shui)(shui)(shui)稻(dao)(dao)恶(e)(e)(e)苗(miao)(miao)(miao)病(bing)是我区水(shui)(shui)(shui)稻(dao)(dao)上最主要(yao)的种(zhong)传病(bing)害，由区农技(ji)中心抽样送检经市农技(ji)中心检测，今(jin)年(nian)我区水(shui)(shui)(shui)稻(dao)(dao)主要(yao)种(zhong)植品种(zhong)稻(dao)(dao)种(zhong)恶(e)(e)(e)苗(miao)(miao)(miao)病(bing)平(pi♏ng)均带菌率为(wei)3.6%，最高8%，带菌率较去(qu)年(nian)略低。但鉴于去(qu)年(nian)田(tian)间发病(bing)普遍，今(jin)年(nian)恶(e)(e)(e)苗(miao)(miao)(miao)病(bing)仍存在(za🅠i)较大流行风(feng)险。稻(dao)(dao)种(zhong)药(yao)剂处(chu)理(li)是控制(zhi)水(shui)(shui)(shui)稻(dao)(dao)种(zhong)传病(bing)害最经济有效的措施，为(wei)此希望各(ge)街(jie)镇及广(guang)大种(zhong)植户引起高度重视，认(ren)真做好水(shui)(shui)(shui)稻(dao)(dao)种(zhong)子(zi)处(chu)理(li)工(gong)作，为(wei)今(jin)年(nian)水(shui)(shui)(shui)稻(dao)(dao)高产(chan)丰收打下(xia)良(liang)好的基础。具体技(ji)术要(yao)求如下(xia)：
一、晒种选种
播前选晴好天气晒种1～2天，并精(jing)选种子，除去秕(bi)粒病粒、减(jian)少菌源，以(yi)提(ti)高种子的发芽势，增强(qiang)秧(yangꦅ)苗抗(kang)病能(neng)力(li✤)。
二、制剂治疗空气消毒能力
1、操作方式方法：
每4kg稻(dao)(dao)(dao)种(zhong)(zhong)(zhong)（亩用(yong)种(zho🅘ng)(zhong)(zhong)量）用(yong)浸(jin)种(zhong)(zhong)(zhong)药(yao)(yao✃)剂(ji)9ml，采用(yong)二次(ci)稀释法，先加少量水(shui)调(diao)成浆糊状，然后再加清水(shui)6kg稀释，配成药(yao)(yao)液(ye)。将选过的稻(dao)(dao)(dao)种(zhong)(zhong)(zhong)4kg（亩用(yong)种(zhong)(zhong)(zhong)量）浸(jin)入配成的药(yao)(yao)液(ye)中搅拌均匀，以药(yao)(yao)液(ye)高(gao)出种(zhong)(zhong)(zhong)子2-3cm为(wei)宜。(若稻(dao)(dao)(dao)种(zhong)(zhong)(zhong)数量多(duo)可按上(shang)述(shu)相应比例(li)配制)
2、浸种(zhong)时(shi)(shi)(shi)(shi)(shi)间(jian)：日平(ping)均气温低于20℃，浸种(zhong)时(shi)(shi)(shi)(shi)(shi)间(jian)应为60小时(sh𓆉i)(shi)(shi)(shi)(shi)，20℃以上，浸种(zhong)时(shi)(shi)(shi)(shi)(shi)间(jian)应在48小时(shi)(shi)(shi)(shi)(shi)左右，具(ju)体根(gen)据气温变化(hua)掌握好时(shi)(shi)(shi)(shi)(shi)间(jian)，但浸足(zu)时(shi)(shi)(shi)(shi)(shi)间(jian)是保证药效的关键。
三、主要须知
1、浸种(zhonꦐg)(zhong)收纳空间要(yao)加盖，并放在背阴遮光(guang)处。严禁止蛇皮袋真接(jie)(jie)浸种(zhong)(zhong)，容易影向实际效果。稻种(zhong)(zhong)灭菌后不要(yao)青水(shui)冲冼(xian)，可真接(jie)(jie)沥干催芽插种(zhong)(zho𝔉ng)。
2、去除剂的计量治(zhi)理(li)过(guo)的图片种(zhong)子，勿与ꦅ粮食(shi)(shi)、预混料放置我(wo)们一(yi)起，不了喂食(shi)(shi)禽畜(chu)，更不了来用(yong)作(zuo)加工(gong)厂(chang)预混料或美食(shi)(shi)。
3、口服药物后应禁(jin)止(zhi)药液等(deng)直接的(deꦺ)污水(shui)排放鱼(yu)池、虾塘等(deng)水(shui)产业(ye)农村(cun)养(yang)殖的(de)地(di)方，禁(jin)๊止(zhi)导致的(de)鱼(yu)、虾、蟹身故(gu)。
4𒁏、农约纸(zhi)盒包(bao)装方式遗弃(qi)(qi)物不应随着遗弃(qi)(qi)或自愿(yuan)处治，直接归(gui)还各级政(zheng)府农约纸(zhi)盒包(bao)装方式遗弃(qi)(qi)物回(hui)收利(li)用点。
