温州三熟制模式下油菜品种比较试验

Comparative test of rapeseed varieties under the triple-croppingsystem in Wenzhou

为了筛选适合在温州平原双季稻区开展“油-稻-稻”周年粮油三熟制生产的早熟高产优质油菜品种,本研究对引进的13个油菜品种的生育期、产量、日均产量、品质及经济效益进行评价分析。结果显示,参试品种全生育期变幅在163~170 d,于5月4—11日成熟,阳光131和湘油420于5月4日成熟,基本不影响后茬早稻的正常生产;阳光131产量位居第一,为1 529.4 kg·hm^(-2),比对照沣油737增产3.8%;早3产量其次,为1 491.9 kg·hm^(-2),比对照增产1.2%;H20-04和阳光131净种植效益分别为9 895.3和9 320.8元·hm^(-2),均高于对照沣油737。综上,阳光131生育期短、产量高、种植效益较好,适宜温州平原连作稻区油-稻-稻周年三熟制种植模式,可进一步扩大示范种植。

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 1529.4 kg·hm^(-2),which was 3.8%higher than that of the control Fengyou 737.The yield of Zao 3 was 1491.9 kg·hm^(-2),which was 1.2%higher than that of the control.The net planting benefits of H20-04 and Yangguang 131 were 9895.3 and 9320.8 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.
