研究了 2种施肥水平下、4种浓度的BR12 0 浸种及苗期处理对小麦生长发育的影响。结果表明 ,BR12 0浸种及苗期处理 ,对不同施肥水平下小麦幼苗的生长、生理生化指标及产量构成因子均有一定程度的改善。其中以 0 .1mg/L浓度处理以及在高肥条件下的效果最佳 ,单株产量在高肥区增产 11.7% ,差异达显著水平 ,而在低肥区增产 5 .8% ,差异不显著
The effects of BR12 0 seed treatment and seedling stage treatments on the growth and development of wheat under the two fertilization levels were studied. The results showed that BR12 0 soaking seeds and seedling stage could improve the growth, physiological and biochemical indexes and yield components of wheat seedlings under different fertilizer levels. Among them, the treatment with 0 .1 mg / L concentration and the best effect under the conditions of high fertilizer yield per plant yield increased 11.7% in the high-fat area, the difference was significant level, but yield increased 5.8% in the low-fat area, the difference was not significant
