沸石在国外研究已有一定的历史,在工农业上有着广泛应用。我国近几年来做了大量研究工作,其中缙云县用沸石粉保肥改土已经取得显著成绩。据介绍,沸石粉拌氨水或碳酸氢铵施用,有很多好处:1.能减少氨气挥发和铵离子流失,起到保肥和保护农作物作用;2.调整土壤酸碱度,提高土壤中阳离子交换容量,改善土壤的物理化学性能;3.吸收和保持水分,提高抗旱能力。根据试验对比,水稻、大小麦、玉米、番薯等,拌施沸石粉后,一般都
Zeolite in foreign studies have a certain history, in agriculture and industry has a wide range of applications. In recent years, our country has done a lot of research work, among which, Jinyun County has achieved remarkable success by using zeolite fertilizer for soil improvement. According to reports, the zeolite flour ammonia or ammonium bicarbonate application, there are many benefits: 1. To reduce the ammonia volatilization and ammonium ion loss, play a fertilizer and protect crops; 2. To adjust the soil pH, increase the cation exchange capacity in the soil , To improve the physical and chemical properties of soil; 3. Absorption and retention of water to improve drought resistance. According to the experimental comparison, rice, wheat, corn, sweet potato, etc., after mixing zeolite powder, are generally
