Planting method of Brassica napus Youfei No.1

Abstract

The invention discloses a planting method for a cabbage type oilseed rape oil fertilizer I. The method comprises the following specific steps: firstly ditching and draining; before seeding, spraying and applying an NPK compound fertilizer as a basal manure; then seeding in a spring seeding or autumn seeding mode, wherein direct seeding is mainly adopted for seeding, the seeding amount per mou is determined by the date of seeding; mainly enabling leaves to grow before buds of the oil fertilizer I appear, enabling flowering cabbage to rapidly grow after the buds appear; when the main flowering cabbage is higher than 15cm, performing primary picking; after primary picking, performing additional application of a nitrogen fertilizer so as to promote growth and development of side flowering cabbages; picking once every several days until flowering cabbages are over during the stage of full bloom; and finally, performing plowing and green manuring according to the farming season requirement of succession crops, and performing decomposed manure fermentation after plowing and green manuring, thereby finishing planting. The cabbage type oilseed rape oil fertilizer I obtained by the method has the advantages of prematurity, excellent flowering cabbage flavor, high fresh grass yield during the stage of full bloom, balanced contents of nutrient ingredients subjected to green manuring, dual functions as vegetable and fertilizer and the like.

Description

technical field [0001] The invention belongs to a planting method of rapeseed, in particular to a planting method of Brassica napus Youfei No. 1. Background technique [0002] Green manure plays an important role in improving soil, fertilizing soil, protecting agricultural ecological environment, and promoting sustainable agricultural development. However, because green manure planting itself does not produce direct economic benefits, farmers are generally not very enthusiastic about planting, which restricts the development of green manure industry to some extent. How to maximize the production potential of existing green manure varieties and bring into play their comprehensive economic efficiency is an important issue in the development of the current green manure industry. [0003] After the approval of Youfei No. 1, it was demonstrated in more than 10,000 mu in 2015. Because of its advantages such as low seed price, wide sowing period, large growth volume, and good soil...
