Introduction And Prospect Of Brassica Napus In Guangxi

In this paper,the agronomic traits and growth stages of Brassica napus were introduced,and the varieties of Brassica napus cultivars suitable for the Guangxi Autonomous Region were selected according to the survey results.On this basis,the questionnaire was designed to analyze and analyze the cultivation,processing and consumption prospect of rapeseed in Guangxi Autonomous Region.The main findings are as follows:1.Through the introduction of the region outside the excellent varieties of Brassica napus(Shu you 169,Ke le you 1,Fang pai you za 17,Mian xin you 58,Nan you za 1,He you 202,Zhe you 51,Zhe shuang 72,Zhe you 50,Zhong shuang 6,Hua you za 6,Hua you za 10,Sheng guang 77,Zhong you za 12,Hua you za 12,Yang guang 2009,Hua shuang 4,Shengguang 127)The results showed that the first effective height,plant height,the main inflorescence pod number,the main inflorescences pod density,the main inflorescence yield,the first effective branch number,the length of the main inflorescence,the main inflorescence per keratin Number and total number of pods).The results showed that the plant height,the main inflorescence pod number,the length of the main inflorescence pod and the total number of pods per plant had a significant effect on the main inflorescence yield,and the other traits affected the main inflorescence production to varying degrees.The plant height,the number of main flower pods,the length of the main inflorescence and the total number of pods per plant were positively correlated with grain yield.Therefore,to improve the yield of rape,should pay attention to plant height,the main inflorescences pod,the length of the main inflorescence and the main inflorescence of the four data.By variance analysis,Ke le you 1,Hua you za 6,Sheng guang 77,Zhong you za 12,these four varieties can be introduced in Guangxi.2.As local farmers in the agricultural production process to invest less,the rough production methods,low technical content,resulting in the lack of mechanized production in the region,low efficiency and other issues.In addition,the area of winter cultivated land idle area is too large,there is no effective use,resulting in a lot of waste of resources.Rape seed introduction prospects are more optimistic.
