一种苏打盐碱地种植专用肥的研究

Study on Special Fertilizer for Planting on Soda Saline Alkali Soil

松嫩平原是中国重要的粮食主产区和商品粮基地,同时也是中国最大的苏打盐碱地,但是由于长期使用化肥,土壤盐渍化日益加重,直接阻碍和影响了该地区的农业生产,作为东北的大粮仓,影响到国家的粮食安全。为此,解决土壤盐渍化的问题,并同时提高农产品产量,增加农民的经济效益,开展了此项研究。此研究是根据盐碱地的理化特性,利用工业农业废弃物,采用配伍干燥、吸附包裹、生物工程技术,开发了一种针对苏打盐碱地的专用肥料。通过两年时间,在盐碱地多点种植玉米、水稻,粮食产量增加10%左右,土壤盐碱化逐步改善。结果表明,使用此肥料,一方面可以提高苏打盐碱地农产品的产量,另外一方面还可以修复改良土壤,恢复地力,降低盐碱度,实现苏打盐碱地区农业生产的可持续发展。

Songnen Plain is not only an important main grain producing area and commercial grain base in China, but also the largest soda saline alkali land in China. However, due to the long-term use of chemical fertilizer, soil salinization is increasing, which directly hinders and affects the agricultural production in this area. As a large granary in Northeast China, it affects the national food security. Therefore, in order to solve the problem of soil salinization,improve the output of agricultural products and increase the economic benefits of farmers, the research was carried our.According to the physical and chemical characteristics of saline alkali land, a special fertilizer for soda saline alkali land was developed by using industrial and agricultural wastes via compatible drying, adsorption and wrapping and bioengineering processes. Over the past two years, corn and rice have been planted in many places in saline alkali land,the grain yield has increased by about 10%, and the soil salinization has been gradually improved. It was concluded that the use of this fertilizer can not only improve the yield of agricultural products in soda saline alkali land, but also repair and improve the soil, restore soil fertility, reduce salinity, and realize the sustainable development of agricultural production in soda saline alkali area.
