水(shui)(shui)(shui)(shui)稻(dao)恶苗病(bing)是我区水(shui)(shui)(shui)(shui)稻(dao)上最主(zhu)要的种(zhong)(zhong)(zhong)传病(bing)害(hai)，由区农技(ji)中心(xin)抽样送检经市农技(ji)中心(xin)检测，今(jin)年(nian)(nian)我区水(shui)(shui)(shui)(shui)稻(dao)主(zhu)要种(zhong)(zhong)(zhong)植品种(zhong)(zhong)(zhong)稻(dao)种⛎(zhong)(zhong)(zhong)恶苗病(bing)平均♉带菌率为(wei)3.6%，最高8%，带菌率较(jiao)去年(nian)(nian)略低。但鉴于去年(nian)(nian)田间发(fa)病(bing)普遍，今(jin)年(nian)(nian)恶苗病(bing)仍存在较(jiao)大(da)流行风险。稻(dao)种(zhong)(zhong)(zhong)药(yao)剂(ji)处理是控制(zhi)水(shui)(shui)(shui)(shui)稻(dao)种(zhong)(zhong)(zhong)传病(bing)害(hai)最经济(ji)有(you)效(xiao)的措施(shi)，为(wei)此希望各(ge)街镇及广大(da)种(zhong)(zhong)(zhong)植户引起高度(du)重(zhong)视，认真做好水(shui)(shui)(shui)(shui)稻(dao)种(zhong)(zhong)(zhong)子处理工作，为(wei)今(jin)年(nian)(nian)水(shui)(shui)(shui)(shui)稻(dao)高产丰收打下良好的基础。具体技(ji)术(shu)要求如下：
一、晒种选种
播前选(ꦫxuan)晴好(hao)天气晒种1～2天，并(bing)精选(xuan)种子(zi)，除去秕粒(li)(li)病粒ꦫ(li)(li)、减(jian)少菌(jun)源，以提高种子(zi)的发芽势，增(zeng)强秧(yang)苗抗病能力。
二、解毒剂(ji)加工杀菌技术水平
1、治疗步骤：
每4kg稻种(zhong)(zhong)(zhong)(zhong)(zhong)（亩用(yong)(yong)种(zhong)(zhong)(zhong)(zhong)(zhong)量）用(yong)(yong)浸种(zhong)(zhong)(zhong)(zhong)(zhong)药剂(ji)9ml，采用(yong)(yong)二次稀释法，先(xian)加少量水(shui)调成浆(jian🍌g)糊状，然后再加清水(shui)6kg稀释，配(pei)成药液(ye)。将选过(guo)的(de)稻种(zhoꦍng)(zhong)(zhong)(zhong)(zhong)4kg（亩用(yong)(yong)种(zhong)(zhong)(zhong)(zhong)(zhong)量）浸入(ru)配(pei)成的(de)药液(ye)中搅(jiao)拌均匀，以药液(ye)高(gao)出种(zhong)(zhong)(zhong)(zhong)(zhong)子2-3cm为宜。(若稻种(zhong)(zhong)(zhong)(zhong)(zhong)数量多可按上述相(xiang)应比(bi)例配(pei)制)
2、浸(jin)种时(shi)(shi)❀(shi)间(jian)：日平均气(qi)温低于20℃，浸(jin)种时(shi)(shi)(shi)间(jian)应(ying)为(wei)60小时(shi)(shi)(shi)，20℃以(yi)上，浸(jin)种时(shi)(shi)(shi)间(jian)应(ying)在48小时(shi)(shi)(shi)左右，具体根据气(qi)温变化掌握好时(sh🥃i)(shi)(shi)间(jian)，但浸(jin)足时(shi)(shi)(shi)间(jian)是保证药效的关键。
三、目光需要注意的
1、浸(jin)种场所是需要(yao)(yao)盖，并(bi⛄ng)放于阴冷闭(bi)光处。严禁止使用(yong)蛇皮(pi)ꦿ袋可以直(zhi)接的(de)浸(jin)种，免得不(bu)(bu)良(liang)影响(xiang)成果(guo)。稻种紫外线灯消毒后不(bu)(bu)是需要(yao)(yao)纯净(jing)水冲冼，可可以直(zhi)接的(de)沥干催芽载种。
2、去除剂的计(ji)量操作过的种子(zi)💖视(shi)频下载，勿与吃的东西、预混(hun)料(liao)放(fang)于一切(qie)，不(bu)能喂养禽畜(chu)，更不(bu)能中用处理预混(hun)料(liao)或调(dia﷽o)味品。
3、施(shi)药后应禁🐽(jin)(jin)止(zhi)药液等(deng)直接性流(liu)进养(yang)(yang)鱼(yu)塘、虾塘等(deng)水产业(ye)养(yang)(yꦆang)殖厂(chang)的敌(di)方，禁(jin)(jin)止(zhi)会(hui)造(zao)成鱼(yu)、虾、蟹牺牲。
4、农约打包废料物不(bu)准自由丢去(qu)或进行治理(li)，迅(xun)速交(jiaoღ)还派出机关农约打包废料物再利用点。
