Embodiment 1

[0024] This embodiment provides a cultivation method for improving the planting benefit of rapeseed by applying fertilizer in narrow rows, the method comprising the following steps:

[0025] Step 1. Sow rape seeds on the wide and narrow rows, the total row spacing between the wide and narrow rows is 40cm; the row spacing between the wide and narrow rows is 1:1;

[0026] Step 2, apply the base fertilizer into the deep soil in the narrow row; the base fertilizer includes 525-675kghm -2 NPK compound fertilizer and 10-15kg hm -2 For boron fertilizer, the content ratio of pure nitrogen, phosphorus pentoxide and potassium oxide in the nitrogen, phosphorus and potassium compound fertilizer is 15%:15%:15%.

Embodiment 2

[0028] In this embodiment, except that the row spacing between the wide row and the narrow row is 2:1 in step 1, other steps are the same as in embodiment 1.

Embodiment 3

[0030] In this embodiment, except that the row spacing between the wide row and the narrow row is 3:1 in step 1, other steps are the same as in embodiment 1.

Abstract

The invention discloses a cultivation method utilizing fertilizer narrow-row furrow application to improve rape planting benefit. The cultivation method includes following steps: directly sowing rape:adopting wide-narrow-row arrangement, and sowing rape seeds on wide rows and narrow rows, wherein row space of the wide rows is greater than that of the narrow rows, and total row space of the wide rows and the narrow rows is 40-60cm; applying base fertilizer into deep-layer soil in the narrow rows, and performing conventional management in the later period. Through rape wide-narrow-row plantingand fertilizer narrow-row furrow application, yield and lodging resistance of rape and resource utilization rate are improved, weed and disease are reduced, yield of high-density planting of the rapeis increased, lodging risk is lowered, production input is reduced, and production benefit of the rape is improved.

Description

technical field [0001] The invention relates to the technical field of high-yield cultivation of crops, in particular to a cultivation method for improving rapeseed planting benefit by applying fertilizer in narrow rows. Background technique [0002] Rapeseed (Brassica nanups L.) is one of the important oil crops in my 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 production of about 4.50×10 6 t, accounting for more than 45% of the total domestic edible vegetable oil. Fertilizer application methods are usually divided into spreading and centralized application. Spreading application is divided into surface application and plowing after application. Concentrated application is divided into furrow application and hole application. Effective fertilization locations can coordinate fertilizer input and crops. abs...
