A Comprehensive Analysis of the Growth Characteristics of Direct-Seeded Rapeseed
Growth Characteristics of Direct-Seeded Rapeseed
(Agricultural Wealth Network) First, the taproot goes deep into the soil: the root system of direct-seeded rapeseed goes deep into the soil, with the taproot reaching up to 50 cm, while the lateral roots and fine roots are concentrated within the 20 cm plow layer, spreading horizontally to 40 cm; second, disease is relatively light: because both sowing and flowering are relatively late, it can to a certain extent avoid the peak infection period of sclerotinia and reduce the incidence of disease; third, individual development is relatively poor: because the whole growth period of direct-seeded rapeseed is short, the individual development time is short, and the productivity per plant is low. Reasonable close planting should be used to obtain high yields; fourth, weeds are prone to occur: in direct-seeded rapeseed fields, weed damage is extremely likely to occur. Chemical weed control is the key technology for achieving full emergence of seedlings in one sowing of direct-seeded rapeseed.
