Large-ridge and double-line under-film drip-irrigation water-saving cultivation method of winter and early spring potatoes

Abstract

The invention discloses a large-ridge and double-line under-film drip-irrigation water-saving cultivation method of winter and early spring potatoes. The method comprises the following steps of (1) potato seed selection and treatment, (2) seeding, (3) drip-irrigation equipment laying and plastic film mulching, and (4) field management. The cultivation method is a water-saving irrigation technology combining a large-ridge and double-line technology, a plastic film mulching technology and a drip-irrigation technology organically, has a particularly remarkable effect in arid and semi-arid regions, integrates the edge line advantage, maintenance of the optimum water content of root regions, effective improvement of the ground temperature, evaporation suppression and water saving, has the characteristics of preserving soil moisture, maintaining fertilizers, keeping warm, remarkably improving utilization of optical energy, water and the fertilizers, saving the water, saving labor, increasing a yield and improving the efficiency, and has the advantages of saving the water and the labor, increasing the yield and improving the efficiency.

Description

[0001] technical field [0002] The invention relates to the technical field of crop planting and agronomy, in particular to a method for drip irrigation and water-saving cultivation of potatoes in large ridges in winter and early spring with double rows of film. Background technique [0003] Potatoes are not only food crops, but also economic crops, which are widely grown all over the world. The development of southwestern winter and early spring potatoes can not only increase the multiple cropping index and increase the total grain output, but also fill the gap in the northern potato supply, which is of great significance to further ensuring national food security and increasing farmers' income. In recent years, winter and early spring potatoes have developed rapidly in the southern region, and have been identified by the Ministry of Agriculture as key areas for future potato development in China. However, in the past three years, there have been severe autumn, winter and...

AI Technical Summary

Problems solved by technology

The traditional ditch flood irrigation method wastes a lot of water resources, coupled with the relative lack of irrigation facilities in these areas, it is no longer suitable for the development requirements of winter and early spring potato production areas

In recent years, although the cultivation of potatoes in Southwest China has made great progress in terms of technology and varieties, it is still relatively weak in adapting to the arid climate environment.
