"Early-onset" is an important measure for the high-yield cultivation of rapeseed. In recent years, the cultivation of rapeseed from the “spring hair†and “winter hair†promoted in the past to the current “fall hair†and “early fall hair†has reached the standard of “early-onset†and the rapeseed sowing time tends to increase. However, a large number of tests and investigations have found that rapeseed sowing time is too early. In case of autumn warm winter cold or winter warm winter cold, not only can not increase production, but it is easy to induce frost damage and reduce production. I used the "Zhongshuang 10" rapeseed for the sowing period test. The same variety, planted in the same plot, the fertility, density, fertilization level and field management are all the same, only the sowing time is different, the results of early sowing because of the moss within the year, the ability of cold resistance decreased, the winter encountered a strong cold and cold invasion, the base More than half of the dead leaves; and appropriate rape sowing, leaves rarely frozen to death. Pre-harvest test production, early sowing of 204.9 kilograms per mu, appropriate sowing of 331.1 kilograms per mu, premature sowing compared with the appropriate time sowing, 126.2 kilograms per acre yield reduction of 38.1%.
This shows that planting rapeseed can not blindly advance the sowing time. Only by adhering to timely planting, good seeding and good methods can we achieve high yields.
