導讀:該標準規定了水稻機插田化肥農藥減施增效技術的品種選擇、種子處理、秧田管理、本田管理等技術。適用于水稻機插田化肥農藥減施生產。

  【農機網 政策與標準】2022年7月11日,河北省市場監督管理局批準發布DB13/T 5598-2022《水稻機插田化肥農藥減施增效技術規程》,該地方標準自2022年8月11日開始實施。
 
  該標準由由河北省農業農村廳提出,由河北省農林科學院濱海農業研究所、唐山久發農業科技有限公司、河北省良牛農業科技有限公司、灤南縣華圃水稻種植園區起草。
 

  該標準規定了水稻機插田化肥農藥減施增效技術的品種選擇、種子處理、秧田管理、本田管理等技術。適用于水稻機插田化肥農藥減施生產。
 
  【本田管理】
 
  秸稈還田:水稻秸稈隨機收粉碎全量還田,秸稈還田按DB13/T 2985的規定執行。
 
  施肥——
 
  肥料選擇:肥料使用符合NY/T 496的規定,化學肥料使用環境安全應符合HJ 555的規定。有機肥料質量符合NY/T 525的規定,生物有機肥質量應符合NY 884的規定,有機-無機復混肥料質量應符合GB/T 18877 的規定,控釋肥料質量應符合HG/T 4215的規定,緩釋肥料質量應符合GB/T 23348的規定,硅肥質量應符合NY/T 797的規定。
 
  施肥原則:采用秸稈還田、有機肥、生物肥及控(緩)釋肥替代為主的減肥措施,結合施用硅肥、減少排水等方法,依據土壤肥力和品種及產量水平,合理控制氮、磷、鉀肥施用量。在減施化肥20%條件下, 實現不減產原則。
 
  施肥方法——
 
  基肥:隨耙地畝施控(緩)釋肥 40 kg,或隨水稻側深施肥插秧一體化技術,畝施控(緩)釋肥 30kg。缺氮稻區選用高氮控(緩)釋肥,缺鉀稻區選用高鉀控(緩)釋肥。施肥后堵好灌排水系統,禁止排水。有條件的在深耕前畝施腐熟農家肥 1500 kg,或商品(生物)有機肥 200 kg,按照其施用量和含量折算后,減施化肥中控(緩)釋肥及追肥中化肥施用量。
 
  蘗肥:緩苗后,畝施入尿素5.0 kg(或硫酸銨 10.0 kg)+40%硅肥5.0kg(秸稈還田地塊免施);第1 次蘗肥施用后7 d、14 d 左右,分別畝施尿素 7.5 kg(或硫酸銨 15.0 kg)。
 
  穗肥:主莖幼穗長到1.0 mm~2.0 mm 時,畝施復合肥(N-P2O5-K2O=15-15-15)7.5kg。
 
  病蟲草害防控——
 
  藥劑選擇:防治藥劑應符合GB/T 8321、NY/T 1276的有關規定。
 
  防控原則:本著“減藥不減效,綠色環保、長效節支”的防控原則,以選用抗病蟲品種為主,優先采用物理、生物防治措施,輔助化學防治措施。
 
  雜草防控——
 
  插前封閉或插后封閉除草采用以下方法進行:
 
  ——插前封閉的,在插秧前7 d,畝施40%丙草胺·芐嘧磺隆可分散油懸浮劑 80 ml~100ml,或68%吡嘧磺隆·苯噻酰水分散粒劑100 g~120g。
 
  ——插后封閉的,在插秧后 7 d~10 d,畝施 53%苯噻酰草胺·芐嘧磺隆可濕性粉劑 80 g~120 g, 或 19%氟酮磺草胺懸浮劑12.5 ml~15 ml,或68%吡嘧磺隆·苯噻酰草胺水分散粒劑100g~120 g。
 
  ——施藥后,田面保持5cm~7cm 水層5d~7d。
 
  封閉效果差或封閉無法防除的雜草采用以下方法進行:
 
  ——扁桿藨草群落畝施 48%滅草松水劑 150 g~200 g,或 5%五氟磺草胺可分散油懸浮劑75ml;
 
  ——大齡稗草+扁桿藨草群落畝施 19%氟酮磺草胺懸浮劑12.5 ml~15 ml,或18%五氟磺草胺+氰氟草酯可分散油懸浮劑80 ml~100 ml,或 2.5%五氟磺草胺乳油 50 ml~120 ml+10%氰氟草酯乳油60 ml~100 ml;
 
  ——水綿+水生雜草群落畝施 25%西草凈可濕性粉劑 125 g,無露水后拌濕潤細沙或土撒施;
 
  ——單一水綿,優先采用排水落干和生物制劑防治。
 
  ——施藥后,田面保持 5cm~7cm 水層5 d~7d。
 
  蟲害防控——
 
  稻水象甲:畝施 25%噻蟲嗪水分散粒劑 40 g~45 g。
 
  二化螟:
 
  物理方法:5月中旬畝安裝性引誘劑裝 1個,誘殺1代二化螟,7月初更換藥芯 1次,誘殺2代二化螟。
 
  化學方法:6月25日左右和8月1日左右各防治1次,畝施40%氯蟲·噻蟲嗪水分散顆粒劑8g,或 20%氟苯蟲酰胺懸乳劑20ml,或20%氯蟲苯甲酰胺懸乳劑 5 g~10g。
 
  稻飛虱:畝施 25%吡蚜酮可濕性粉劑20 g~30 g。
 
  其它蟲類:畝施20%氯蟲苯甲酰胺懸乳劑5 ml~7.5 ml。
