宁夏银北盐碱地枸杞节水技术改良

在宁夏银北盐碱地区平罗县枸杞种植研究基础上,采用沟灌节水灌溉与优化施肥和细沙覆盖技术措施对盐碱地枸杞进行研究,探索盐碱地枸杞发展的节水改良利用新技术。结果表明,3种技术综合应用的节水节肥、保墒抑盐、增产增收效果显著,而且枸杞长势良好,没有因水量减少而导致盐分加重现象出现,使盐碱地得到高效利用,避免大水漫灌和不合理施肥造成的土壤次生盐碱化发生,推广前景广阔。

Water saving Techniques for Improvement of Lycium barbarum L. Production in Ningxia Yinbei Saline Land

Based on the Lycium barbarum L. cultivation in Pingluo Saline Land of Ningxia Yinbei, the furrow irrigation, water saving irrigation, optimized fertilization and sand covering technical measures on Lycium barbarum L. of saline land were deeply studied, to explore the new water saving technology for the improvement of saline land Lycium barbarum L. production. The results showed that the combined applications of three kinds of technologies made remarkable improvement for saving water and fertilizer, moisture conservation and salt restraining, increasing production and incomes. Lycium barbarum L. plants were growing well, salt aggravation did not happen owing to the reduction of water. This made the saline land to be used efficiently, and avoided the occurrence of soil secondary salinization caused by flood irrigation and unreasonable fertilization. It opens up broad prospects for promotion.
