花生-油菜轮作模式下硼肥及其后效对作物产量的影响
Residual effectiveness of different boron fertilizers on seed yield of peanut (Arachis hypogaea L.) for rotated oilseed rape (Brassica napus)
摘要
Abstract
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.关键词
