- 摘要:
- 溶磷菌能将土壤中难溶性无机磷酸盐转化为植株能吸收利用的可溶性磷,从而提高土壤中有效磷含量,促进植株生长发育。分别采用从大豆根际土壤中分离的溶磷菌wj1、wj3及其wj1+wj3混合菌液施入土壤中,研究溶磷菌株对吉林省地区主推大豆品种吉育47、吉育99和吉育406盛花期的光合作用、抗逆作用、生长量以及含磷量的影响。结果表明:溶磷菌菌液处理对3个品种大豆有不同程度的促生作用。wj1和wj3单菌种菌液处理增加了3个品种大豆盛花期的光合作用,混合菌可显著降低盛花期3个品种的蒸腾速率,从而提高植株水分利用率。wj3菌液对大豆盛花期生长量的影响较为显著,对根瘤的生长也有良好的促进作用,wj1和混合菌明显增强3个大豆品种植株的抗性。wj3和混合菌液对吉育406叶片中全磷量影响不显著,其它大豆根茎叶的全磷含量均高于对照。其中,wj1处理的根茎叶中全磷含量与对照相比达到显著水平。因此,wj1的综合促生能力优于wj3,更适合应用于农业生产中。
- Abstract:
- Soybean is the most important oil crops in China, and is one of the crop requiring large amounts of phosphorus, this experiment studied the effect of photosynthesis, resistance effect, mass growth and the total phosphorus content on three kinds of soybean under the condition of adding exogenous phosphorus-solubilizing bacteria-wj1, wj3 and wj1+wj3 mixed bacterial liquid, which has an important role in saving the input of phosphate fertilizer and reducing the cost of soybean in the agricultural production.The photosynthesis, stress tolerance, growth characteristics and phosphate content were determined in florescence stage. The results showed that different bacterial liquid had different levels of growth-promoting effect on different varieties of soybean. The effect of wj3 on the mass growth of three kinds of soybean was significant, also promoted the growth of root nodules. The three treatments had the promotion effect on the growth on Jiyu 406 in fullbloom stage wj1 and wj3 increased the photosynthetic rate on three varieties of soybean, wj1+wj3 significantly decreased the transpiration rate of the three cultivars, and significantly increased the water use efficiency of the plants wj1 and mixed bacteria significantly enhanced the resistance of three cultivars of soybean. In addition to the total phosphorus content in leaves of Jiyu 406 effected by wj3 and mixed bacteria, others in the roots, stems and leaves were significantly higher than the control,and wj1 increased the most. Therefore, the comprehensive promotion of wj1 is better than wj3, and it is more suitable for agricultural production.
