This paper presented effects of four kinds of boron (B) fertilizers, borax (B, Na2B4O7·10H2O), Ulexite granular (UB, NaCaB5O9·8H2O), Etibor-48 (EB, Na2B4O7·5H2O) and Colemanite (CB, Ca2B6O11·5 H2O) on yield of peanut (Arachis hypogaea L.) and their residual effectiveness on seed yield for rotated oilseed rape (Brassica napus) by field trials. Results showed that basal application of B, UB, EB and CB (B 1.70 kg/hm2) increased yield of peanut and oilseed rape in different extent; increasing rate of yield of each rotated crops of double boron application treatments (B 3.40 kg/hm2) decreased inordinately comparing with that of treatments at normal B application rate. The increasing rates of yield of peanut and oilseed rape did not increase with the increasing of B dosage when the hot water soluble boron (HWSB) content of soil was 0.49 mg/kg. The HWSB content of all the B application treatments were higher than 0.5 mg/kg when crop were harvested. The boron content of straw and crop yield were also higher than that of no boron treatment. Basal application of these boron fertilizers could significantly increase the HWSB content. UB and CB, which had a more significant increasing rate in Crop2 and Crop3, could be used as basal fertilizers according to their great slow-release properties and soil available B content in agricultural production.%通过田间试验研究硼砂(B,Na2B4O7·10H2O)、Ulexitegranular(UB,NaCaB5O9·8H2O)、Etibor-48(EB,Na2B4O7·5H2O)和Colemanite(CB,Ca2B6O115H2O)四种硼肥在花生-油菜轮作中的肥效及其后效对作物产量的影响.结果表明,按正常施硼量(纯硼用量1.70kg/hm2)基施硼砂、UB、EB和CB四种硼肥,花生和油菜产量均有不同程度的提高;两倍施硼量(纯硼用量3.40kg/hm2)与正常施硼量相比,不同硼肥处理作物增产率均有不同程度降低,其中土壤有效硼含量0.49mg/kg时,作物增产率并不随施硼量的继续增加而升高.基施四种硼肥,三季作物收获后土壤有效硼含量均高于0.5mg/kg,秸秆硼含量与作物产量也显著高于不施硼处理.基施硼肥可以改善土壤有效硼状况,具有较强缓释性的硼肥UB和CB在第二季和第三季具有较好的增产效果.在农业生产上可以根据土壤有效硼状况和硼肥本身的缓效性作为基施长效硼肥合理推广利用.
