摘要

于2016—2017年以双低油菜‘青杂5号’为供试材料,设置5个施硼处理,采用完全随机区组设计,研究不同施硼量对双低春油菜干物质积累、氮磷钾养分吸收、产量、品质的影响,以期阐明硼对双低春油菜产量、品质形成的影响机理,提出适宜的硼肥施用量,为双低春油菜生产提供理论依据和技术指导。试验结果表明:2016年在施硼量较小的情况下,油菜植株各器官的干物质积累、养分吸收、籽粒产量及品质均随施硼量增加呈逐渐升高趋势,2017年在增大施硼量的情况下,各指标均随施硼量增加呈先升后降趋势,都以施硼量为22.5 kg/hm2时最高,此处理下籽粒产量较不施硼增产28.68%,脂肪含量提高8.06个百分点,蛋白质及芥酸含量均较其他处理有不同程度降低。回归分析表明内蒙古中部旱作地区双低春油菜生产中获得较高产量和产油量的适宜施硼量(纯硼≥15%)为19.96~21.34 kg/hm2。

Abstract

The purpose is to elucidate the effect of boron on the yield and quality of double low spring rape, and to propose a suitable amount of boron fertilizer for the production of double low spring rape. In 2016-2017, using double-low rape‘Qingza 5’as test material, five boron treatments were conducted and a completely randomized block design was adopted, to investigate the effects of different boron levels on dry matter accumulation, NPK nutrient uptake, yield and quality of double low spring rape. The results showed that under the condition of low boron application in 2016, the dry matter accumulation, nutrient absorption, grain yield and quality of rapeseed plants increased gradually with the increase of boron application amount, and increased and then decreased in 2017 with the increase of boron application rate. The best boron application rate was 22.5 kg/hm2. The grain yield under this treatment was 28.68% higher than that without boron, and the fat content increased by 8.06 percentage points, protein and erucic acid content were reduced to varying degrees compared to other treatments. Regression analysis showed that the appropriate amount of boron (Lili Boron: purity boron ≥ 15%) was 19.96-21.34 kg/hm2 for the higher yield and oil yield in the double-low spring rapeseed production in the dry area of central Inner Mongolia.
