摘  要:
在松嫩平原,应用正交试验对苜蓿产量进行行距、灌水、施肥影响研究。结果表明,以30cm行距处理产草量最高,干草产量15389.66kg/hm2;灌水以3次和1次为好;施农家肥22500kg/hm2增产效果好于施磷酸二铵150kg/hm2和施复合肥150kg/hm2处理;施尿素112.5kg/hm2增产效果最佳,平均产干草14673.61kg/hm2;行距30cm、灌水3次、施磷酸二铵150kg/hm2、施氮肥112.5kg/hm2处理产干草19395.83kg/hm2,极显著高于其它处理。

摘  要:
The effect of row spacing,irrigation and fertilizing on alfalfa yield was studied in the Songnen Plain with orthogonal design.The results showed that alfalfa yield with 30cm in row spacing was the highest and the hay yield was 15389.66kg/hm2;irrigating three times and one time had the best effect;the effect of applying barn yard manure 22500kg/hm2 was better than applying ammonium phosphate 150kg/hm2 and compound fertilizer 150kg/hm2;the effect of applying 112.5kg/hm2 urea was the best,the hay yield was 14673.61kg/hm2;the hay yield treated with 30cm in row spacing,irrigating three times,applying 150kg/hm2 ammonium phosphate and 112.5kg/hm2 urea reached 19359.38kg/hm2,which was significantly higher than other treatments.
