The high-quality hybrid rapeseed has a well-developed root system, thick stems, large leaf surface coefficient, many branches, large amount of flowers, and many pods. It is not only of good quality, but also generally has an increase in yield of about 30%. According to the comparison, boron fertilizer was applied to hybrid rapeseed at the seedling stage and the sorghum period, branching increased by 0.97, the number of pods per plant increased by 42.8, the number of degenerate spikelets decreased by 38.4, the number of grains per horn increased by 2.94, and the grain weight increased by 0.34 g , An increase of 30.3 kg per mu. Boron deficiency in high-quality rape is prone to flowering, resulting in reduced yields. Symptoms of boron deficiency in rapeseed: boron deficiency at seedling stage, slow root growth, leaf shrinkage, dark color, severe plant root swelling, purplish red color, stem growth point withered to death; boron deficiency during planting, plant dwarfing, The buds withered, the petals withered and shrivelled; the pods were deficient in boron, the ovules withered, the pods flaking or deformed, and the number of pods decreased, and the clustered branches continued to bloom but were not robust.
