Embodiment 1
[0023] For two consecutive years in 2012-2013 and 2013-2014 in the rape test base of Huazhong Agricultural University in Wuhan City, Hubei Province, the different row spacing and mechanized harvest experiments of Huayouza 62 rapeseed varieties were carried out. The specific steps are as follows:
[0024] 1) Test materials: The first crop of the test field was rice, which was harvested in early September. The plot is 50m in length and 2m in width. Huaza 62 was selected as the variety. On September 23, 2012, the 2BFQ-6 rapeseed combined planter was used for mechanical live broadcast.
[0025] 2) Test method: The test adopts a split zone design. The rapeseed planting density is set to three density levels of 150,000, 300,000 and 450,000 per hectare, which are represented by D1, D2, and D3 respectively, as the main area; the row spacing is set as Three levels of 15cm, 25cm, and 35cm, represented by R1, R2, and R3 respectively, are sub-regions;
[0026] 3) Rapeseed field management: imme...
Embodiment 2
[0043] From 2013 to 2014, a large-scale demonstration of 315 acres of experimental conclusions from 2012 to 2013 was carried out at the demonstration base in Ezhou City, Hubei Province, China, and the current habitual planting mode of farmers was used as a control. In the mature period, the actual output (manual harvest), mechanical harvest output, and mechanical harvest loss rate indicators in the demonstration area were measured to further support the experimental conclusions of 2012-2013 and 2013-2014. Specific steps are as follows:
[0044] 1) Rape variety selection and planting: The first crop of 315 acres of demonstration site was rice, and each field was harvested in early September. The rape variety was Huaza 9 and the 2BFQ-6 type was used for joint sowing on September 27, 2013. The machine conducts mechanical live broadcast. Before planting, install a 60-hole seeding disk on the direct seeding machine, and adjust the distance of the seeder to 21cm. Select 5 points in t...
