剑麻滴灌施肥技术研究

Research on the Drip Irrigation Fertilization Technique of Sisal

目前,在剑麻生产中应用管道(水肥滴灌等)施肥技术的不多,通过管道源源不断地供给剑麻水分、养分,可获得显著的经济、社会及生态效益。研究发现,应用水肥滴灌技术,剑麻肥料投入量是常规栽培的40%左右,有效降低了化肥的投入,提高肥效;同时缓解土壤酸度,改善土壤环境,减轻农工劳动强度;每667 m2剑麻增产1 t。

At present,the application of pipeline fertilization technology(water and fertilizer drip irrigation,etc.)in sisal production is few.Utilizing the pipeline to continuously supply water and nutrients to sisal can obtain significant economic,social and ecological benefits.The results indicate that with the application of water and fertilizer drip irrigation technology,the fertilizer input of sisal is about 40%of the conventional cultivation,which effectively reduces the input of fertilizer and improves fertilizer efficiency;At the same time,it alleviate soil acidity,improves soil environment,reduces the Labor intensity of workers;The sisal yield increased by 1 ton per 667m^(2).
