中文摘要	本研究设置了露地平播、全地面覆膜平播、半覆盖平播、覆膜垄沟播和土垄沟播5个处理,研究了不同覆膜和垄沟技术对土壤水热状况、紫花苜蓿产量和品质的影响;并在覆膜垄沟处理条件下,参照3414施肥试验,研究了不同氮、磷、钾肥料配比对紫花苜蓿产量、品质和土壤肥力的影响。结果表明:覆膜垄沟处理较露地处理在生长前期提高了土壤温度,在返青期、第一次和第二次刈割后提高了0~80cm土壤含水量,并提高了苜蓿的干草产量、粗蛋白和粗脂肪含量。施肥试验中,P_2K_2N_3处理干草产量最高,为6 366kg·hm~(-2),并提高了土壤肥力;粗蛋白、粗脂肪含量最高的处理分别是P_2K_1N_2、P_2K_2N_3;P_2K_1N_2处理的中性洗涤和酸性洗涤纤维含量最低。综上,覆膜垄沟可以改善土壤水热状况,提高苜蓿的产量和品质;施肥处理P_2K_2N_3,即P_5O_260kg·hm~(-2),K_2O 45kg·hm~(-2), N 92kg·hm~(-2),综合效果较好,是垄沟覆膜条件下的最佳施肥处理。
英文摘要	In this study,the treatments of no mulching,full film,half-full film,mulching ridge,soil ridge were set up, and the effects of different mulching and furrow techniques on soil water and heat conditions,yield,and quality of alfalfa were studied.Furthermore,according to the"3414" fertilization experiment,the effects of different nitrogen,phosphorus, and potassium fertilizer ratios on the yield,quality,and soil fertility of alfalfa were studied under the mulching ridge treatment condition.The results showed that,compared to the no mulching treatment,the mulching ridge treatment increased the water content of 0to 80cm soil after the plant turned green,the 1st cutting and 2nd cutting,increased soil temperature in the early growth period and increased hay yield,crude protein and crude fat of alfalfa.In the fertilization experiment,the P_2K_2N_3treatment had the highest hay yield of 6 366kg·hm~(-2) and improved soil fertility;the treatments with the highest crude protein and crude fat content were P2K1N2and P_2K_2N_3respectively;the P_2K_1N_2 treatment had the lowest neutral detergent and acid detergent fiber content.In conclusion,the mulching ridge treatment can improve the soil water and heat conditions and increase the yield and quality of alfalfa.The fertilization treatment of P_2K_2N_3(P_5O_260kg·hm~(-2),K_2O 45kg·hm~(-2),and N 92kg·hm~(-2))has a better overall effect and is recommended as the best fertilizer treatment under the mulching ridge.
