Study on Shooting and Young Bamboo Growth Rhythm of Brachystachyum densiflorum (Rendle) Keng
摘要
Abstract
[Objective]The study aimed to study the law of shoot of Brachystachyum densiflorum (Rendle) Keng, in order to lay a foundation for scientific cultivation, rapid propagation and protection of Brachystachyum densiflorum.[Method]Shooting period was observed for one time every two days, investigation on the biological characteristics of bamboo shoot, mature bamboo, degraded shoot, the base diameter, and the shoot height data of Brachystachyum densiflorum was conducted.The nonlinear regression analysis of height growth of Brachystachyum densiflorum shoots was carried out by Logistic.[Result] The experiment showed that Brachystachyum densiflorum shoots lasted 24 d,with degraded shoot rate of 10% as standard, the shooting periods of Brachystachyum densiflorum was divided into early, peak and late stages.In the early period and peak period, the number of shoots increased rapidly, and the duration was shorter.At the end of a slow decline in shoot number, lasted for a long time.In the peak period, the most bamboo shoots were degraded, and the main reasons for degraded shoots were dry and insect pests.The height growth of young bamboo with growth trend of "slow fast slow", the fitting degree of growth curve model with Logistic was higher, the fitting degree was 0.999.[Conclusion]Through the investigation of shooting and young bamboo growth rhythm and study on the growth and development regularity of shoot period of Brachystachyum densiflorum,provide a basis for scientific breeding of short spike bamboo and rational management.关键词
