摘要

A method to treat spring rape fields is characterized by that prior to sowing an additional mineral fertilizer is applied into the soil in an amount of 12-15 g/m2 together with a plant growth regulator in an amount of 8 ml/ha whereupon the soil surface is levelled by rollers. Further the treated rape seed is sown into the prepared soil, and after the sowing the soil surface is treated with a 0.01-0.02% chitozane solution, mulched, packed by rollers and it is treated again with the plant growth regulator and with 0.01-0.04% chitozane solution.
