新疆地区滴灌小麦复播大豆施肥技术研究

Study on Fertilizer Application System of Soya Multiple Cropping in Wheat Drip Irrigation Fields in Xinjiang Uygur Autonomous Region

在新疆地区进行滴灌小麦复播大豆栽培技术试验研究,试验年限为3年,2009年主要进行滴灌小麦复播大豆灌溉制度研究,得出最佳灌水量为3600m3·hm-2,全生育期灌水7次。2010年在此基础上进行滴灌小麦复播大豆施肥制度研究,通过对不同施肥处理生育期生长情况调查、大豆植株性状及产量调查、复播大豆成本及效益分析,总结出滴灌小麦复播大豆的施肥处理为尿素150kg+三料磷肥375kg+磷酸二氢钾225kg·hm-2时,大豆的产量最高。通过试验证明了在新疆地区进行滴灌小麦复播大豆是可行的。

Soybean multiple cultivation experiment was carried out in the drip infusing wheat fields to fint out the planting techniques and measures in Xinjiang region. The experiment was scheduled in three years. 2009 was the first year,when the irrgation system was abtained with infusion volume of 3 600 m3·hm-2 and seven times irriagtion frequecy in the whole growing period. On infromations of the crop growth conditions, soybean characteristiics in the different processing period of fertilizers treatment, the soybean coutput, cost and the benefit analysis,It was summarized in 2010 that under the condition of fertilizer applied for urea 10 kg＋ three material phosphate fertilizer 25 kg ＋ potassium dihydrogen phosphate 225 kg·hm-2, soybean’s output was highest. The results showed that it was feasibale to conduct soya multiple cropping in wheat drip irrigation fields in Xinjiang Uygur Autonomous Region.
