導讀:華北黃淮墑情適宜站點與墑情過多站點較6月24日監(jiān)測略有降低,墑情不足至重旱站點略有升高。

  【農機網(wǎng) 熱點關注】 據(jù)6月27日全國農技中心土壤墑情監(jiān)測,華北黃淮0-20cm土壤相對含水量均值為74.18%,20-40cm土壤相對含水量均值為81.38%,較6月24日監(jiān)測數(shù)據(jù)略降。從0-20cm土層看,49.15%監(jiān)測站點墑情適宜,9.65%站點墑情不足,9.34%站點干旱,17.56%站點重旱,14.30%站點墑情過多;從20-40cm土層看,56.04%監(jiān)測站點墑情適宜,9.81%站點墑情不足,7.75%站點干旱,13.13%站點重旱,13.26%站點墑情過多。
 
  總體看,華北黃淮墑情適宜站點與墑情過多站點較6月24日監(jiān)測略有降低,墑情不足至重旱站點略有升高。干旱地區(qū)主要分布在河北中部、山西南部、山東東部及南部局地等未灌溉農田和無灌溉條件的旱地。
 
  據(jù)氣象預報,未來10天,華北黃淮大部有25mm以上降雨,其中華北東部、黃淮東部和南部累計降水量有50—120mm,江蘇及安徽大部降水量達100—250mm,預計華北黃淮土壤墑情將進一步改善。當前出現(xiàn)干旱地塊要持續(xù)抓好抗旱保苗,如玉米苗已打蔫要及時灌溉,補墑降溫。灌水時間盡量避開午后高溫時段,小水澆灌,保證田間不積水。及時開展查苗補種,對缺苗斷壟地塊補種。
