不同种植方式对饲用谷草生产性能的影响OA

This experiment aimed to precisely screen the most suitable forage foxtail millet varieties for saline-alkali soils in the Hetao Irrigation District.A field trial was conducted in saline-alkali land of the Hetao Irrigation District in Inner Mongolia to compare the effects of drilling and hill sowing on plant height,panicle length,and fresh and hay yields of four Zhangqinggu varieties(No.1,2,3,and 5).The results showed that the plant height and panicle length of Zhangqinggu No.1,2,and 5 under hill sowing were significantly higher than those under drilling(P＜0.05).Under drilling,Zhangqinggu No.1 had the highest plant height(163.70 cm),which was significantly greater than that of the other varieties(P＜0.05),while Zhangqinggu No.2 had the lowest plant height(139.78 cm).Zhangqinggu No.5 exhibited the longest panicle length(23.70 cm),significantly exceeding the other varieties(P＜0.05),whereas Zhangqinggu No.2 had the shortest panicle length(17.43 cm).Under hill sowing,Zhangqinggu No.1 achieved the highest plant height(175.33 cm),significantly surpassing the other varieties(P＜0.05),and Zhangqinggu No.5 had the longest panicle length(25.53 cm on average),significantly greater than that of the other varieties(P＜0.05).The fresh and hay yields of Zhangqinggu No.2 under hill sowing were significantly higher than those under drilling(P＜0.05).Zhangqinggu No.5,whether under drilling or hill sowing,produced significantly higher fresh and hay yields than the other varieties(P＜0.05).The study demonstrates that Zhangqinggu No.5,with its high yield,salt tolerance,and outstanding panicle length,is suitable for promotion.Hill sowing can enhance yield by optimizing light energy and resource allocation,providing a technical basis for forage production and improvement in saline-alkali lands.
