Sowing Time of Different Brassica napus Varieties in Shigatse

doi:10.11923/j.issn.2095-4050.cjas17060004

Abstract

Abstract: This paper aims at selecting proper cultivation varieties of Brassica napus in Shigatse, Tibet. Variety ‘2137’,‘Qingza 4’,‘Qingza 7’and‘Jinghua 165’introduced from Qinghai Academy of Agricultural Sciences were used as materials. The growth period, economic traits and yield traits were studied by means of different sowing time. The results showed that the growth period was shortened and the plants’economic traits, yield components and yield decreased with the postponing of sowing time. The yield was the highest when the sowing was carried out on April 27, and sowing after May 17 could probably make the plants expose to early frost of autumn and result in the failure of natural maturity. Therefore, the appropriate sowing time of B. napus varieties in Shigatse can be set in late April.
