| 摘 要： | 在黑龙江省齐齐哈尔市,应用正交试验设计对苜蓿进行行距、灌水、施肥种类及施氮肥试验。试验结果表明,行距以30 cm处理产草量最高,每公顷产干草11 049 kg,比45 cm处理增产干草9.9%,差异显著(P<0.05);以灌水1次为好;施农家肥22 500 kg/hm2产干草11 403 kg/hm2,增产效果最佳,比施复合肥150 kg/hm2增产干草17.1%(P<0.05)和施磷酸二铵150 kg/hm2增产干草6.6%(P<0.05),施磷酸二铵比施复合肥增产9.8%(P<0.05);施尿素112.5 kg/hm2增产效果好于施尿素75 kg/hm2和150 kg/hm2处理;处理6(行距30 cm,灌水3次,施磷酸二铵150 kg/hm2,施氮肥112.5 kg/hm)2和处理2(行距15 cm,灌水2次,施农家肥22 500 kg/hm2,施氮肥112.5 kg/hm)2分别产干草11 818 kg/hm2和11 730 kg/hm2,显著高于其他处理。

| Abstract: | The experiments were carried out in Qiqihaer of Hei Long Jiang to study the effects of row spacing,irrigation,different types of fertilizer on alfalfa grassland.The results showed that the treatment with row spacing 30 centimeter was the highest in yield of herbages,and its dry yield of herbages was 11049 kg/hm2,which was increased by 9.9%(P<0.05)compared to the row spacing 45 centimeter;Irrigating for one time was the best.Treatment of applying farmyard manure 22500 kg/hm2 was the best for increasing yield,its dry yield of herbages was 11403 kg/hm2 which was increased by 17.1%(P<0.05) compared to applying compound fertilizer150kg/hm2,increase by 6.6%(P<0.05) compared to applying ammonium phosphate fertilizer 150kg/hm2,and applying ammonium phosphate was better(increased 9.8% in yield,p<0.05) than applying compound fertilizer.The effects of applying urea fertilizer 112.5 kg/hm2 was better than that of applying 75kg/hm2 and 150kg/hm2.The dry yield of herbages of treatment 6(row spacing 30 centimeter;irrigating for three times,ammonium phosphate fertilizer 150 kg/hm2;nitrogen fertilizer 112.5 kg/hm2) and treatment 2(row spacing 15 centimeter;irrigating for two times;farmyard manure fertilizer 22500 kg/hm2;nitrogen fertilizer 112.5 kg/hm2) was 11818kg/hm2 and 11730kg/hm2 respectively,which was higher than that of other treatments greatly. |
