石灰氮在设施蔬菜土壤质量提升中的应用

由于设施蔬菜产业的发展及设施土壤管理的盲目性,设施土壤出现土传病虫害加重、土壤酸化、土壤板结、土壤盐渍化、土壤有机质匮乏、土壤营养失衡等退化现象。为此,介绍石灰氮的特性、石灰氮在土壤中的转化,分析石灰氮在设施蔬菜土壤质量提升中的作用,如土壤消毒、土壤改良、提供氮钙营养、促进秸秆腐熟等。并在此基础上,提出了设施蔬菜生产中太阳能-石灰氮土壤消毒技术,制订了太阳能-石灰氮土壤消毒全程实施方案。

Application of Lime Nitrogen on Improving Greenhouse Vegetable Soil Quality

As the development of greenhouse vegetable industry and blind mangement of soil in greenhouse ,greenhouse soil begin to degenerate , including soil-borne disease, acidification,agglutination, salinization,deficiency of organic matter, nutrition imbalanced,and so on.There fore, The characteristics and transformation in soil of lime nitrogen was introduced , lime nitrogen can improve greenhouse vegetable soil quality through soil fumigatio,soil amelioration, supplying nitrogen and calcium nutrition, promoting straw decomposition and so on.Based on this, disinfection technology was put forward by using solar energy-lime nitrogen for greenhouse vegetable soil, implementation scheme of the technology was estab-lished.
