Abstract

The leaf nitrogen content, grain appearance quality, nutritional quality and yield performance of Zhehexiang 2 were studied under the condition of different basal tiller fertilizer and panicle fertilizer. The results showed that, the nitrogen content in the 4th inverted leaf increased with the application of basal tiller fertilizer, and the nitrogen content in the 1st inverted leaf changed with the application of panicle fertilizer; under the same nitrogen application, the panicle fertilizer had a greater impact on the leaf nitrogen content. Under the condition of basal tiller fertilizer with low nitrogen, there was no significant difference in the nutritional quality and appearance quality of different treatments. When basal tiller fertilizer (pure nitrogen) was above 0.120 t/hm2, reducing panicle fertilizer could decrease chalky rice rate and protein content, and increase amylose content. Within the range of 0~0.24 t/hm2 of nitrogen fertilizer (pure nitrogen), the yield was increased with the increase of nitrogen application rate, and the application of panicle fertilizer has a great influence on yield. However, reducing the application of panicle fertilizer could significantly increase the taste value. Considering the quality and yield, it is appropriate to apply 0.045 t/hm2 panicle fertilizer for Zhehexiang 2.
