Comparison experiment on introduced forage rape ( Brassica napus) cultivars growth after wheat harvesting in agro-pastoral ecotone of Ganzi Prefecture
摘要
Abstract
[Objective]The present study was conducted to study the ecological adaptability and total daily intake quantity of forage rape (Brassica napus) in order to supply elite forage rape germplasm resources for growth after harvesting wheat in the agro-pastoral ecotone of Ganzi Prefecture. [Method]From July to October,2011,experiment on cultivar comparison and yak intake of two introduced forage rape (Brassica napus) cultivars (Siyou 1 and Huaxie 11),extended in large area in northwest China,was carried out by using two main double-low erucic acid rape cultivars in Sichuan production as control; ecological adaptability of the two introduced cultivars,yak intake speed,and total daily intake quantity were investigated and studied. [Result]In agro-pastoral ecotone of Ganzi Prefecture,Siyou 1 and Huaxie 11 could grow regularly with the fresh yield of 34296.16 and 30573.75 kg/ha,respectively,yak intake speed and total daily intake quantity of Siyou 1 were 61.19 g/mhvyak and 14.73 kg/yak,respectively,those of Huaxie 11 were 62.91 g/min-yak and 15.15 kg/yak,respectively,which were all significantly higher than the control. [Conclusion]Siyou 1 and Huaxie 11 could be extended and planted as forage rape after harvesting wheat in the agro-pastoral ecotone of Ganzi Prefecture.关键词
