沸石可做土壤改良剂,改善土壤的理化性能,增加肥力。用于畜牧业,也可做为饲料添加剂及饲养场粪便、污水的处理剂。我省沸石资源丰富,应该大力推广应用,使之尽快产主经济效益。一、在农业上的应用 1、土壤改良剂:沸石之所以能作为土壤改良剂,是因为它具有很强的盐基交换作用,除了吸收水分外,对肥料成份的吸附率也很高。如对氨的吸附率为85.5％,磷为90％,钾为80％。因此它的保肥能力较强,有利于作物的生长。日本生产的沸石土壤改良剂已出口台湾和东南亚。苏联把沸石作为肥料添加剂施入不需要灌溉的土壤中,可使作物提高产量。如:小麦可提高13.9-28％,土豆20％,饲草10-15％。 2、沸石碳酸氢铵:碳酸氢铵是我国独创的氮肥品种。它的优点是速效、经济、松土、不板地、防病虫害、有利于光合作用等。
Zeolite can be used as soil improver to improve soil physical and chemical properties, increase fertility. For livestock husbandry, but also can be used as feed additives and feedstuffs, sewage treatment agent. Zeolite rich in resources in our province should be vigorously promote the application so that the economic benefits of the owner. First, the application in agriculture 1, soil improver: The reason why zeolite can be used as soil improver, because it has a strong salt-based exchange, in addition to absorbing water, the adsorption of fertilizer ingredients is also high. Such as ammonia adsorption rate of 85.5%, 90% phosphorus, potassium 80%. Therefore, its strong ability to retain fertilizer is conducive to crop growth. The zeolite soil conditioner produced in Japan has been exported to Taiwan and Southeast Asia. The Soviet Union uses zeolites as fertilizer additives in soils that do not require irrigation, allowing crops to increase yields. Such as: wheat can be increased by 13.9-28%, potatoes 20%, forage 10-15%. 2, Zeolite Ammonium bicarbonate: Ammonium bicarbonate is China’s original nitrogen fertilizer varieties. Its advantages are quick, economical, loose soil, not plate, pest control, is conducive to photosynthesis.
