一、中后期林果政策（早起水、养草灭草）
视当(dang)年度气候、茬口种植，可在3月(yue)下-4月(yue)初进行第一次早(zao)(zao)上(shang)水(shui)。上(shang)水(shui)要求：上(shang)透(tou)大水(shui)，保水(shui)3-5天后待(dai)自然落干(gan)，促(cu)稻田(tian)杂草(cao)(cao)、杂草(cao)(cao)稻种子早(zao)(zao)萌发早(zao)(zao)出(chu)苗，待(dai)长(zhang𒉰)出(chu)后耕翻灭除。如不(bu)影响后续播(bo)栽进度，可进行第2次早(zao)(zao)上(shang)水(shui)早(zao)(zao)出(chu)草(cao)(cao)的养(yang)草(cao)(cao)灭草(cao)(cao)工作(zuo)。严格落实1-2次养(yang)草(cao)(cao)灭草(cao)(cao)工作(zuo)，可有效降(jiang)低田(tian)间杂草(cao)(cao)、杂草(cao)(cao)稻基数。
二、化除技术水平
1、机主播(bo)稻田分为“二封一杀”化除技术工艺
特(te)别注(𒉰zhu)意须知：田(tian)(tian)板应该整(zheng)齐(qi)，药后(hou)田(tian)(tian)间(jian)地头增(zeng)加湿软(ruan)，并搞(gao)好沟系，以防止下雨过(guo)后(hou)污水。有播喷同部(bu)的(de)设(she)备的(de)，可在直播稻机械制造(zao)种植同一(yi)时间(jian)，做(zuo)出半封闭施🐼药。
2、机插秧稻田应用“写份一(yi)杀”化除技术水(shui)平
三、解决办法控制措施
刚开始(shi)化除后莎(sha)草(cღao)仍(reng)较多的苗圃地，应视草(cao)相，促使对应修(xiu)复机制。
补除前先排干(gaꩵn)水，药后(hou)1天上水，保(bao)水3-5天后(hou)ꦯ恢复正常管(guan)理。禁止超(chao)范围补水喷(pen)雾，会造成药害。
四、注重事宜
1、对前(qian)年水(shui)草(cao)（水(shui)草(cao)稻）的(de)造(zao)成比较(jiao)严重(zhong)田园，应搞好播栽前(qian)的(de)现(xian)代(dai)农业防除方法(fa)，写好“𓄧1次(ci)冲水(shui)、1次(ci)耕翻”岗位，才能(neng)减少水(shui)草(cao)𒊎（水(shui)草(cao)稻）的(de)造(zao)成缴(jiao)存基数(shu)。
2、稻田要认真整(zheng)(zheng)地，保(bao)持(chi)整(zheng)(z๊heng)齐(qi)。修善好(hao)水稻田前(qian)提场地设施，使田埂系(xi)统(tong)，水沟畅通无阻，保(bao)持(chi)更好(hao)的保(ba🤪o)水和提灌功(gong)能表(biao)。
3、只能表明(m🎶ing)裁(cai)培的(de)方式和(he)草相，合适(shi)更准选择(ze)适(shi)用(yong)(yong)(yong)药(yao)水(shui)品(pin)类和(he)施药(yao)做(zuo)法(fa)，适(shi)用(yong)(yong)(yong)时要只能表明(ming)农药(yao)杀虫(chong)剂标鉴的(de)适(shi)用(yong)(yong)(yong)做(zuo)法(fa)科学合理适(shi)用(yong)(yong)(yong)。而且，目光田块排水(shui)🍸障碍(ai)和(he)药(yao)雾(wu)影向附近牙齿种(zhong)植的(de)农物(wu)，进(jin)而诞生药(yao)害(hai)。
4、药(yao)后如遇(yu)雨要及时清理沟(gou)系(xi)，打开(kai)缺口，防(fang)止积(ji)水淹(yan)没(mei)水稻心𝄹叶(ye)而产生药(yao)害。施(shi)药(yao)后当天或第二(er)天遇(yu)大暴(bao)雨，应(ying)减量补施(shi)，药(yao)量掌𝔍握在(zai)原(yuan)使用量的50%。
前中期(qi)化除(chu)及补除(chu)个性(xing)化推荐应用药物制剂(ji)常见𓆏等(deng)详请(qing)咨询服务日本飞防监管(guan)部门。
