不同氮磷钾施肥水平对厚朴生长的影响
Effects of Different N, P, K Fertilization Amount on the Growth of Magnolia officinalis
摘要
Abstract
Objective] The aim was to study effects of different N, P, K ratio fertilization on the growth of Magnolia officinalis plants. [ Method] With high quality Magnolia officinalis plants as test material, through field experiment and indoor analysis, using different ratio of N, P, K fertilizer, the indicators of tree height, DBH, N, P, K content were determined, the relationship between fertilization and yield and quality of Magnolia officinalis plants was analyzed. [Result] Different fertilization amount of N, P and K could increase tree height of 11. 3%-56. 5%, DBH of 10. 2% -48. 4%, improve N content 2. 6% -22. 2%, P content 1. 5% -10. 4%, K content 12. 2% -40. 0%. And there was a significant correlation between indicators and N, P, K. [ Conclusion] The appropriate N, P, K ratio is conductive to the growth of Magnolia officinalis plants, the ratio of N, P, K fertilization amount as 1. 00:0. 44:2. 67 has significant influence to the growth.关键词
