摘要
针对土默川平原地区苜蓿种植生产中施肥不合理、肥料利用率低等问题,在该地的和林盛乐园区及沙尔沁乡试验区,开展了配方施肥技术在草原2号杂花苜蓿(MedicagovariaL.cv.Caoyuan No.2)生产中的应用研究。采用"3414"施肥方案设计,以化肥做种肥,于生长第2年第1次刈割后追施混合的"水溶肥"和"菌肥"。通过对不同施肥水平下牧草产量的测定分析,探讨土默川地区苜蓿生长过程中适宜的施肥水平。结果表明,和林盛乐园区试验区每公顷施入尿素163kg和重过磷酸钙293.4kg时苜蓿干草产量最高,沙尔沁乡试验区每公顷施入163kg尿素与硫酸钾150kg时苜蓿干草产量最高。
Aimed at the Tumochuan plains medicago planting fertilization unreasonable, fertilizer utilization rate is low, in the Helin Shengle Park and ShaErQin test area, to carry out the technology of formula fertilization application research of Medicago varia cv. Caoyuan No. 2 production（Medicago varia cv. Caoyuan No. 2）. Using ＂3414＂ fertilization program design, to fertilizer for fertilizer, in the growth of the 2 years of the first harvest after mixing of ＂Water soluble fertilizer＂ and ＂Bacterial Fertilizer ＂. Through under different fertilization levels on forage yield determination and analysis of Tumochuan region medicago growth process in the appropriate level of fertilization. The results shows that, the yield of medicago was highest when adding urea 163kg and heavy calcium superphosphate 293.4kg in Helin Shengle Park, the yield of medicago was highest when adding urea 163kg and potassium sulphate 293.4kg in ShaErQin test area.
