膜下滴灌水肥一体化技术在色素辣椒生产中的应用

Application of integrated water and fertilizer technology of drip irrigation under film mulching in the production of pigment pepper

新疆是制干椒优势产区,目前膜下滴灌技术已在色素辣椒种植上大面积应用,但在其生产中仍存在水肥资源浪费严重、水肥供应不协调、耦合效应差、产量和品质不高等问题,把水肥一体化技术与色素辣椒生产实践结合起来,从品种选择、地块的理化性状、平整土地、滴灌系统布置与管理、种植模式及群体指标、色素辣椒各生育期的水肥管理和配套栽培措施等方面,阐述了水肥一体化技术在色素辣椒生产中的应用技术要点,形成了具有普遍指导性的水肥一体化技术规范。

Xinjiang is an advantageous production area for dry pepper.At present,drip irrigation under film has been widely used in the planting of pigmented pepper,but there are still some problems in its production,such as serious waste of water and fertilizer re⁃sources,uncoordinated water and fertilizer supply,poor coupling effect,low yield and quality.This study combines the water and fer⁃tilizer integration technology with the production practice of pigmented pepper from the aspects of physical and chemical properties of the plot,land leveling,drip irrigation system layout and management,planting mode and population index,water and fertilizer man⁃agement and supporting cultivation measures of pigmented pepper in each growth period,and expounds the application technical points of water and fertilizer integration technology in pigmented pepper production,and forms a universal guiding technical specifica⁃tion of water and fertilizer integration.
