Abstract:

Film mulching is an effective technology for yield increase of dry cultivation, which can significantly improve the ecological condition of soil moisture and temperature, and promote plant growth and development. In order to understand the effects of film mulching cultivation on the growth, yield and quality of spring rapeseed in Tibet, based on field cultivation with ‘Shanyou No.4’ as the material, the effects of film mulching cultivation on the growth period, dry matter accumulation, agronomic characters, yield and quality of spring rapeseed were analyzed. The results show that compared with open field cultivation, the film mulching cultivation could shorten the growth period by 5 days, increase the plant height, branching position, effective branch number, effective pod number per plant, seed number per pod, and decrease 1000-grain weight. The yield of film mulching cultivation was 2601.67 kg/hm2, increased by 508.34 kg/hm2 compared with that of open field cultivation, and the yield increase rate was 24.28%. The oil content was increased by 2.4%, while the content of erucic acid and glucosinolates did not change much. The study indicates that the film mulching cultivation can improve the yield and quality of spring rapeseed in Tibet, and can be used as an important cultivation measure in the production.

Key words: Tibet, film mulching cultivation, spring rapeseed, growth, yield, quality, effect
