通过对优质、高产杂交油菜新品种黔油17号在贵州8个不同油菜生态区域进行的稻田免耕移栽和稻田翻犁移栽两种不同种植方式的对比试验结果得出:在稻田免耕移栽种植方式下,杂交油菜新品种黔油17号的产量水平与传统的稻田翻犁移栽相当或约高于稻田免耕移栽,其稻田免耕移栽和稻田翻犁移栽的平均产量分别为166.74kg/667m2、158.95kg/667m2,单位面积上的纯收益分别为192.52元/667m2、42.27元/667m2,稻田免耕移栽明显地高于传统的稻田翻犁移栽种植方式;同时稻田免耕移栽种植方式可降低黔油17号的植株高度、有效分枝高度,增加单株有效角果数,缩短生育期,使黔油17号在相同的条件下提早成熟5d
By comparing the two different planting methods of no-tillage transplanting and paddy transplanting in paddy field of Guizhou province, which is a new rapeseed variety with high-quality and high-yielding hybrid rice variety Qianyou 17, Under the transplanting method, the yield of hybrid oil rapeseed rapeseed Qianyou 17 was equivalent to or slightly higher than that of traditional paddy field tillage transplanting, and the average of the yield of non-tillage transplanting and paddy field transplanting in paddy field The yields were 166.74kg / 667m2 and 158.95kg / 667m2, respectively. The net profit per unit area was 192.52 yuan / 667m2 and 42.27 yuan / 667m2, respectively. The no-till transplanting of paddy field was obviously higher than that of the traditional transplanting and transplanting of paddy field. At the same time, no-tillage transplanting in paddy field could reduce the plant height and effective branch height of Qianyou 17, increase the number of effective pods and shorten the growth period of Qianyou 17, so that Qianyou 17 prematurely matured under the same conditions for 5 days
