水肥一体化技术在老挝旱季花生生产上的应用效果研究

目的]研究水肥一体化技术在老挝旱季花生生产上的应用效果。方法]在老挝万象开展了水肥一体化模式下不同施肥量对旱季花生产量和经济效益影响的试验。结果]与当地常规模式相比,水肥一体化技术能增加花生发芽率、株高、平均荚数、百粒重等,最终能显著提高老挝花生的产量,增产量达1 000 kg/hm~2,增产率为51.9%,同时还能节省人工成本,增加农民收入,能增收2 800元/hm~2。水肥一体化模式下施肥量为91.5 kg/hm~2能使老挝旱季花生生产达到最佳产量。结论]在老挝旱季推广水肥一体化技术将对当地农业发展起到重要的作用。

Application Effect of Water and Fertilizer Integration on Peanut Production in Dry Season in Laos

Objective] To study the application effect of water and fertilizer integration on peanut production in dry season in Laos.Method] The effects of different fertilization on peanut yield and economic benefit under water and fertilizer integrated model were studied in Vientiane,Laos.Result] Using water and fertilizer integrated technology could increase the germination percentage,plant height,the average pods number and hundred-grain weight of peanuts compared with the conventional planting pattern.The peanut yield significantly increased by 1 000 kg,/hm2 and 51.89％.It also could save labor costs and increase farmers' income by 2 800 yuan/hm2.The optimum yield application rate of fertilizer was 91.5 kg/hm2 by using water and fertilizer integration in dry season in Laos.Conclusion] Using water and fertilizer integration in dry season will play an important role in the development of local agriculture in Laos.
