| 摘 要： | 针对云南紫花苜蓿Medicago sativa种植缺乏专用肥的研究,采用"3414"的试验设计来研究不同基肥配比对紫花苜蓿第1年产量、株高、叶茎比、单株质量的影响.试验得出,施N 57.3 kg/hm2、P2O5 138 kg/hm2、K2O 36.45 kg/hm2时年产最高,达104 865 kg/hm2;施N 129.3 kg/hm2、P2O5 -5.1 kg/hm2(视为不施磷肥)、K2O 82.5 kg/hm2时茎叶比最大,达52.12%;施N 79.35 kg/hm2、P2O5 73.05 kg/hm2、K2O 106.05 kg/hm2时株高最大,达61.56 cm;施N 24.9 kg/hm2、P2O5 79.05 kg/hm2、K2O 80.1 kg/hm2时单株质量最高,达5.58 g.

| Abstract: | The special fertilizer for alfalfa has seldom been studied in Yunnan Province.The effects of various basal fertilizer proportion on yeild,stem length,leaf / stem ratio and individual weight of alfalfa in the 1st year were investigated according to "3414" design in field experiments.In the first year,the highest-yield of alfalfa is 104,865 kg per hm2 with the basal fertilizer proportion: N 57.3 kg,P2O5 138 kg,K2O 36.45 kg;the highest leaf / stem ratio of alfalfa is 52.12% with the basal fertilizers proportion:N 129.3 kg,P2O5-5.1 kg(regarding as no P2O5),K2O 82.5 kg;the highest stem length of alfalfa is 61.56 cm with the basal fertilizer proportion: N 79.35 kg,P2O5 73.05 kg,K2O 106.05 kg;and the highest individual weight of alfalfa plants is 5.58 g with the basal fertilizer proportion: N 24.9 kg, P2O5 79.05 kg,K2O 80.1 kg. |
