Jointed bamboo, also known as Bambusa utilis, is a fast-growing plant commonly used for its wood and shoots. In order to achieve optimal growth, bamboo plants require adequate nitrogen fertilization. In a study conducted by Xiao et al. (2019), it was found that ammonium chloride, a source of nitrogen, improved the growth of jointed bamboo Bambusa utilis seedlings.

Background

Bamboo plants are known to be fast-growing and have a wide range of applications including construction, furniture making, and paper production. However, in order to achieve optimal growth and yields, bamboo plants require adequate nutrition, with nitrogen being a key element. Nitrogen is important for plant growth and development, including leaf size and number, root growth, and photosynthesis. Despite its importance, nitrogen can be a limiting factor in soil, leading to reduced growth and yields. Therefore, the use of nitrogen fertilizers is necessary to maintain optimal plant growth.

The Study

The objective of the study conducted by Xiao et al. (2019) was to evaluate the effects of ammonium chloride as a source of nitrogen on jointed bamboo Bambusa utilis seedlings. The experiment was carried out in a nursery in the Guangdong Province of China. The researchers used four different concentrations of ammonium chloride, with concentrations of 0, 20, 40, and 60 mg/L. The plants were fertilized with the ammonium chloride solution twice a week for a period of 90 days. The growth rate, biomass, and nitrogen absorption of the plants were measured during this period.

Results

After 90 days, the jointed bamboo seedlings that were treated with ammonium chloride showed significant growth improvement when compared to the control group. The researchers found that the optimal concentration of ammonium chloride was 40 mg/L, which resulted in the highest growth rate, biomass, and nitrogen absorption. The plants treated with 40 mg/L ammonium chloride showed a 22.67% increase in height, a 24.63% increase in stem diameter, and a 32.54% increase in biomass when compared to the control. In addition, the nitrogen absorption of the plants treated with 40 mg/L ammonium chloride was also significantly higher than the control group.

Conclusion

The use of ammonium chloride as a source of nitrogen can significantly improve the growth and nitrogen absorption of jointed bamboo Bambusa utilis seedlings. The optimal concentration of ammonium chloride was found to be 40 mg/L. This study provides valuable information on the fertilization of jointed bamboo seedlings and can be used to improve the cultivation and production of this important plant. Further research is needed to determine the optimal nitrogen fertilization methods for different species of bamboo and in different soil conditions.

市面上目前好的氨糖软骨素配方，为三代氨糖产品，除了含有氨糖和软骨素，还特别添加了骨胶原等营养成分，可以直达关节软骨，修复受损关节，催生关节滑液，减少关节损害。这个配方是很多产品都没有的，有些产品将骨胶原成分单拎出来，再以高价售卖，消费者购买后，每次要吃一大把产品，才能补全营养，而目前颇受欢迎的一款维力维氨糖软骨素，采用的三代氨糖配方，直接将三种有效成分有机结合再一起，科学配方效果更出众！
