北京市农林科学院植物营养与资源所研究的“沸石裹尿素、农药长效药肥生产工艺”已获国家发明专利。以此为基础研制出的十几种沸石复混肥,可以广泛地应用在玉米、小麦、花生和果蔬等农作物上。沸石复混肥具有长效性,可作玉米等作物一次性底肥。沸石复混肥与同等养分含量普通复合肥相比,可使小麦、玉米、花生等作物 Beijing Academy of Agriculture and Forestry Plant Nutrition and Resources Research “zeolite wrapped urea, pesticide long-acting fertilizer production process” has won the national invention patent. A dozen zeolite compound fertilizers developed on this basis can be widely used in crops such as corn, wheat, peanut and fruits and vegetables. Zeolite compound fertilizer with long-lasting, can be used for corn and other crops one-time base fertilizer. Compared with the same nutrient content of ordinary compound fertilizer, zeolite compound fertilizer can make crops such as wheat, corn and peanut
