Abstract

The invention relates to a treating agent for promoting early viability of machine transplanted blanket-shaped seedlings of oilseed rape and an application method thereof, belonging to the field of agricultural technology. The treating agent is prepared from the following ingredients: 1.25mg / L of gibberellin, 40g / L of urea, 150mg / L of monopotassium phosphate, 950mg / L of calcium nitrate tetrahydrate, 600mg / L of potassium nitrate, 3.0mg / L of boric acid, and the balance of water. 600ml of treating agent is sprayed to a blanket-shaped seeding tray per square meter in 3-7 days before machine transplanting, and the treating agent can effectively promote the early viability of machine transplanted blanket-shaped seedlings of the oilseed rape.

Description

technical field [0001] The invention relates to the technical field of rapeseedling treatment, in particular to a treatment method for rapeseed blanket-shaped seedlings, which belongs to the field of agricultural technology. It involves the use of common urea and the growth-regulating substance gibberellin to form a solution of a certain concentration for spraying seedling treatment, so as to promote early viability of rapeseed blanket seedlings after machine-transplanted in field. Background technique [0002] Seedling cultivation and transplanting rapeseed has always been planted in seedbed cultivation and manual transplanting. This method uses a lot of labor, labor intensity is high, and production efficiency is low. From 2009 to 2014, Yangzhou University and the Nanjing Institute of Agricultural Mechanization of the Ministry of Agriculture of China jointly explored a new cultivation mode of machine-transplanted rapeseed. Through the combination of agricultural machinery ...
