摘要: 摘要:为了充分发挥高粱在旱作作物中的高产作用,寻求适应该区种植的新模式,本文从耕作、施肥以及施肥量三个方面进行了研究,得出了“两改一优”的栽培模式。试验结果表明:比传统种植0~20cm土壤耕层水分提高31.16~35.55%,产量增加27.69~28.71%,氮素表观利用率提高4.18%~5.26%,水分利用率提高24.52%~27.38%。

Abstract: Abstract: This paper study the effects of cultivation, fertilization and the quantity of fertilization for sorghum yield, in order to find a new planting mode for the Arid and Semi-arid Area. The results showed that , the water raised 31.16~35.55%, the yield increased 27.69~28.71%, the apparent utilization of nitrogen increased 4.18%~5.26%, the utilization of water increased 24.52%~27.38%.
