Description

In the pot experiment, the content of total water-soluble carbohydrates (TSC) in stubble, leaves and shoots temporally decreased following nitrogen fertilization during early growth duration, after which it again increased, and that of each part of plants in the pots fertilized increasing nitrogen decreased more than that of each part of plants in light nitrogen. The content of TSC was higher in stubble than in leaves, and that of parts of plants decreased by tillering. Nitrate-nitrogen content decreased following nitrogen fertilization and gradually increased. However, it tended to decreased at the end of experiment. Crude protein content rapidly increased immediately following nitrogen fertilization, however, it gradually decreased. In the field experiment, the content of TSC decreased when new leaf emerged after the start of plant growth and then increased rapidly, but decreased after seed ripening.
