Problems solved by technology

The harvest of rapeseed year after year coincides with the season of summer harvest and summer planting in southern my country. The traditional manual harvesting method is cumbersome and labor-intensive. The labor cost remains high. The production efficiency of rapeseed is extremely low. The acreage of rapeseed in the production area has been hovering for a long time

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...

Abstract

The invention belongs to the technical field of rape cultivation and particularly relates to a cultivation method capable of reducing a mechanized harvesting loss rate of rape and application thereof. The method mainly comprises the steps of performing seed dressing of humic acid, ammonium molybdate, agricultural chitin and rape seeds according to the weight ratio of (0.8-1):(0.4-0.6):(0.4-0.6):(0.18-2.2); sowing seeds according to the planting spacing of 20-22 cm and the plant density of 420000-480000 plants per hectare, selecting and installing a seeding disc with 55-60 meshes on a 2BFQ-6 type rape united sowing machine so as to optimize the seeding amount of direct seeding rape, obtaining the optimized direct seeding rape planting spacing, and accordingly reducing the mechanized harvesting loss rate of direct seeding rape. After the method is adopted, on the conditions of a rational fertilization model and an appropriate seeding time, the silique layer of the direct seeding rape per hectare is high, the silique is concentrated, the method has the advantages of high yield, falling resistance and pod dehiscence resistance, the mechanized harvesting loss rate at the mature stage is low, and the rape production benefit is obviously improved.

Description

Technical field [0001] The invention belongs to the technical field of rapeseed cultivation, and specifically relates to a cultivation method for reducing the loss rate of mechanized harvesting of rapeseed and its application. Background technique [0002] my country is the world's largest rapeseed producing country, and its planting area and total output account for more than 30% of the world's rapeseed area and total output. Rapeseed oil is also the largest edible vegetable oil produced in my country, with an annual output of about 4.50×10 6 t, accounting for more than 41% of the total domestic edible vegetable oil. Compared with foreign oilseed rape production, my country's traditional oilseed rape production method employs more labor, heavy labor, and high labor costs, resulting in low efficiency of my country's oilseed rape production and weak international competitiveness. Numerous production practices in various regions have shown that the mechanized production of rapesee...
