Study on the Growth Rhythm of Michelia chapensis Dandy
摘要
Abstract
[Objective] The aim was to study the growth law of M. Chapensis. [ Method] Through observing the growth condition of M. Chap-ensis seedlings and biennial and perennial plants, the growth law of M. Chapensis was studied. [ Result ] The average height of 1 -year-old M. Chapensis seedlings was 89.6 cm with average ground diameter of 1.40 cm, main root length of 32. 1 cm, root cap of 34.6 cm×30.9 cm, and ＞5 cm I grade lateral roots of 13.8 strips. The plants grow very fast, so 11-year-old plants can reached the average diameter at breast height of (30.07 ±3.63) cm,the plants height of (935 ±117. 83)cm and the crown of (548 ±41.42)cm . The growth peak of plants height and stem were from July to August. If the water and fertilizer management could be strengthened, the average growth rate of plants would be promoted, and the diameter at breast height and plants height as well as the crown would reach 4. 91, 121 and 79 cm, respectively. [ Conclusion ] The study provides the reference for the culture and quality identification of M. Cheapnesis, and is beneficial to its popularization and application.关键词
