摘要
为筛选适宜在黑龙江省规模化种植的饲料油菜品种及栽培模式,采用多年多点的田间定位方法,研究了不同品种、不同种植方式和播期的产量差异和施肥效应以及不同收获期产量及营养成分积累规律。结果表明:金油158、15-P15和12-P38的产量表现好;采用机播平作,播种量15 kg/hm^2,底肥施磷酸二铵150 kg/hm^2,4月22日早播,能够显著提高饲用油菜的生物量。盛花期收获,饲用油菜生物量相对较高,推测其与玉米秸秆混合青贮,制成配合饲料较好。本文结果为饲料油菜在我国北方早熟区开展多功能开发利用提供了参考。
Animal husbandry is severely restricted by insufficient grass production in northern pastoral areas in China. To improve forage rapeseed(Brassica napus L.) for large-scale planting in Heilongjiang Province, yields of several rapeseed varieties were analyzed on nutrient accumulation and fertilization effect under different cultivation modes by multi-point field tests. Results showed that yield advantages of Jinyou 158, 15-P15 and 12-P38 were relatively high. High yield was obtained under conditions of 15 kg/hm^2 weight of sowing seeds, 150 kg/hm^2 diammonium phosphate and forage rapeseed planted early on April 22. The biomass was relatively high in flowering time and better silage would be made by mixing with corn straw. This research was expected to provide reference for multifunctional utilization of forage rapeseed in the precocious zone of northern China.
