两种不同含量的速溶硼肥,solubor和宽甸硼砂施用于油菜新品种中双9号、华双3号、中油杂2号和华杂3号的田间试验结果表明,施硼增加油菜苗期、越冬期、初花期干物重,增加株高、主花序长度、分枝数、单株角果数、粒数和粒重,而叶数、根茎粗和千粒重变化不明显;不同施硼菜籽产量平均增加5.7%～20.1%,喷施等量0.075%、0.10%、0.15%硼肥溶液,solubor优于宽甸硼砂,增产率分别为13.3%、18.3%、20.1%和5.7%、9.9%、15.2%;喷施等量有效硼时,两种硼肥的油菜单株粒重及菜籽产量均相近。表明两种硼肥对双低常规油菜与双低杂交油菜均有相似的显著增产效果,其增产率取决于有效硼施用量;在低硼土上,可满足双低油菜产量达2500～2800kg/hm2的硼素需求为每公顷喷施宽甸硼砂5.7kg或solubor硼肥2.85kg。
The results of field experiments of applying two kinds of instant boron fertilizer, solubor and Kuandian borax to new rapeseed varieties Zhongshuang9, Hua Shuang3, Zhongyouza2 and Huazha3 showed that boron application increased the seedling stage of rape , Dry weight at the beginning of flowering stage, increased plant height, length of main inflorescences, number of branches, number of pods per plant, number of grains per plant and grain weight, while the number of leaves, rhizomes and grain weight did not change obviously; The yield increased by 5.7% ~ 20.1% on average, spraying equivalent amount of 0.075%, 0.10%, 0.15% Boron solution, solubor was superior to Kuandian borax, the yield was 13.3%, 18.3%, 20.1% and 5.7%, 9.9% , 15.2%, respectively. When applying the same amount of available boron, the grain weight per plant and the rapeseed yield of two kinds of boron fertilizer were similar. The results showed that the two boron fertilizers had similar yield increase effect on double low conventional rapeseed and double low hybrid rapeseed. The yield increase was dependent on the effective boron application rate. On the low boron soil, the yield of double low rapeseed reached 2500 ~ 2800kg / The boron requirement for hm2 is 5.7 kg for Kuandian borax or 2.85 kg for solubor boron fertilizer per hectare.
