Comparative test of rapeseed varieties under the triple-cropping system in Wenzhou
In order to select early-maturing,high-yield and high-quality rapeseed varieties suitable for the annual production of"rapeseed-rice-rice"triple-cropping system in Wenzhou Plain,the growth period,yield,average daily yield,quality and economic benefits of 13 introduced rapeseed varieties were evaluated and analyzed.The results showed that the variation of the whole growth period of the tested varieties was 163-170 days and matured from May 4th to 11th,while Yangguang 131 and Xiangyou 420 matured on May 4th,which did not affect the normal growth of early rice.The yield of Yangguang 131 ranked first,which was 1 529.4 kg·hm-2,which was 3.8%higher than that of the control Fengyou 737.The yield of Zao 3 was 1 491.9 kg·hm-2,which was 1.2%higher than that of the control.The net planting benefits of H20-04 and Yangguang 131 were 9 895.3 and 9 320.8 yuan·hm-2,respectively,which were higher than those of the control Fengyou 737.In summary,Yangguang 131 has a short growth period,high yield and good planting efficiency,which is suitable for the annual triple-cropping planting mode of"rapeseed-rice-rice"in the continuous rice area of Wenzhou Plain,and the demonstration planting can be further expanded.
