Abstract

Pot experiment was conducted using a japonica rice cultivar Ningjing 3, to investigate the effect of transplanting pattern on growth and nutrients uptake of rice seedlings under wheat straw returning. The results showed that the tiller number, plant height, dry weight and nutrients uptake were decreased under wheat straw returning. Compared with the non-straw returning, the tiller number, dry weight of upper and underground parts, and root activity of rice seedlings with wheat straw returning 20 days after transplanting were decreased by 17.3%, 29.4%, 11.5%, and 14.0%, respectively. Compared with conventional hand transplanting, the upper part dry weight, tiller number, plant height and upper part nitrogen content of machine transplanting decreased under wheat straw returning condition, the root dry weight and activity 20 days after transplanting were decreased by 57.1% and 26.1%, respectively. The seedling growth of machine transplanting rice is more vulnerable to be stunted by short-term straw returning, which is caused by inhibited root growth and impaired root activity.
