盐碱地枸杞节水高效利用技术集成研究

为了改良并高效利用盐碱地、有效推动平罗盐碱地枸杞产业的发展,开展枸杞沟灌、覆盖黑膜、优化施肥技术集成研究已成为宁夏引黄灌区盐碱地农业可持续发展的迫切需要。研究结果表明:沟灌+覆膜+优化施肥技术集成下,节水、抑盐、抑制杂草效果极为显著,有效节约水分的同时土壤根层含水量充足、盐分下降12.3%,土壤养分得以改善、微生物活性增强,枸杞生长发育及品质良好、产量较农民习惯种植增产68%、获得纯收入增加93%。该技术集成的研究对于指导盐碱地枸杞高产高效发展有重要意义。

Study on Integration of Water-Saving and Efficient Using Technology For Wolfberry of Saline Land

In order to improve and efficiently use saline land、effectively promote the development of Pingluo saline land wolfberry industry, start technology integration research of wolfberry Furrow Irrigation and Black Film Covering and Optimized Fertilization has become an urgent need of sustainable development of saline land in Ningxia Yellow River Irrigation. The results showed that Furrow irrigation+film covering+Optimize Fertilization technology integration, water-saving、salt suppressing,、weed suppressing effect was extremely significant, effectively saved water while the soil root zone moisture was adequate、salt was down 12. 3%, soil nutrient was improved、microbial activity was en-hanced, wolfberry growth and quality were good、yield increased 68% comparing with farmers planting habits、getting net income increased 93%. The technology integration research which guiding saline wolfberry high yield and efficiency development is important.
