泾川县属暖温带半湿润半干旱气候,约80%的农村人口生活在干旱半干旱地区,是典型的水资源短缺旱作农业区。多年来,为解决水资源短缺与粮食生产及经济作物发展效益低下的突出问题,在推进农田水利设施建设和推广传统旱作技术的前提下,上世纪80年代引进推广了地膜覆盖玉米栽培技术后,农膜的应用规模逐年扩大,应用技术不断创新,有力地提升了旱作农业综合生产能力,确保了全县粮食安全,为农业增产、农民增收做出了极大贡献。但是,大量废旧农膜没
Jingchuan County is a warm temperate semi-humid and semi-arid climate. About 80% of the rural population live in arid and semi-arid areas, which is a typical drought-scarce agricultural area with water shortage. Over the years, in order to solve the outstanding problems of water shortage and ineffective development of grain production and cash crop, under the precondition of promoting the construction of irrigation and water conservancy facilities and popularizing the traditional dry farming techniques, the technology of mulching and covering maize was introduced and popularized in the 1980s , The application scale of agricultural plastic membrane has been expanded year by year. The continuous innovation of applied technology has effectively promoted the comprehensive production capacity of dry farming agriculture, ensured the food security of the whole county, and made great contributions to increasing agricultural output and increasing peasants’ income. However, a large number of discarded plastic sheeting did not
