双垄全膜覆盖沟播栽培技术在雨养区农业生产上的应用,提高了降水利用率,实现了田间雨水的集流和富集叠加利用,从根本上解决了土壤水分无效蒸发问题,有效地改善了土壤水分及温度条件,对农业增产起到了积极的作用。但是全膜覆盖又增加了生产投入成本,在一定程度上出现了增产不增收的现象。因此,为充分利用现有资源,减少浪费,降低生产成本,采用“一膜两年用”栽培模式,达到节本增收 The application of double-ridge full film mulching and sowing cultivation technology in agricultural production in rain-fed area increased the utilization rate of precipitation, realized the collection and enrichment of rainwater in the field, and solved the problem of invalid evaporation of soil moisture effectively. Improve the soil moisture and temperature conditions, the agricultural production has played a positive role. However, full film coverage has increased the cost of production inputs, to a certain extent, there has been an increase in yield without increasing the phenomenon. Therefore, in order to make full use of existing resources, reduce waste and reduce production costs, adopt the “one film, two years” cultivation mode to achieve the section cost increase
