Since 1982, Yangzhou has experimented on the effect of boron fertilizers on the yield increase of oil raisins and obtained the effect of increasing output of 8.4-9.6% of mu and increasing value of 12.07-25.74 yuan. (I) Test to promote soil fertility group of Lixiahe District Agricultural Science Institute of Jiangsu Province, Yangzhou Agricultural Bureau Soil Fertilizer Station and the relevant county agricultural station, from 1982 to 1984, rapeseed application of boron fertilizer, the results show that the stimulation effect Good and stable. According to the statistics of 2 years and 16 experiments and 35 sub-projects, the average increase of boron fertilizer by 14.8 kg compared with the control averagely increased by 11.9%.
