Description

Bamboo forest directional cultivation method for tea-pole bamboo raw bamboo material utilization
The invention relates to an oriented cultivation method of mixed-growth bamboo seeds for high-quality materials, in particular to an oriented cultivation method of bamboo forests for utilization of raw bamboo materials of tea-rod bamboos.
Background
At present, bamboo resource utilization in China is mainly scattered bamboos and assisted by clumpy bamboos, and development and utilization of mixed-grown bamboo resources are relatively lagged. The tea-stem bamboo is a high-quality multi-axis mixed-growing type bamboo seed, and the central producing area is in towns such as ancient water, pits, depression and the like in Guanning county and Huanjing county of Zhaoqing city in Guangdong province. The bamboo has straight bamboo pole, long internode, flat wall thickness, strong compression resistance, high fiber content and good quality. The bamboo material is washed by sand, is white like ivory, is not easy to be damaged by worms and has strong corrosion resistance, and the bamboo ash is white and not carbonized after being burnt, so the bamboo material is also called steel bamboo and is a traditional export commodity bamboo in China. However, the development of the tea-rod bamboo products is still in the early stage, the courtyard fence is one of the most common products, and other processed products comprise toothpicks, crop supporting rods and the like, and the technical content and the additional value of the processed products are not high.
The tea rod bamboo is excellent in material, but the advantages of the tea rod bamboo are not brought into play in the traditional processing products, in order to fundamentally change the situation, many practitioners try to develop tea rod bamboo raw bamboo furniture, lamps, artware and the like, and a good industrial direction is formed, particularly, the tea rod bamboo small raw bamboo is attractive in line type, good in processing performance and good in hot bending performance, and the manufactured raw bamboo furniture and other products are exquisite, flexible, simple and elegant, and have good market development prospects. However, due to the limitation of the conditions of the existing tea-rod bamboo forest, the cutting yield of the original bamboo is not high, and sustainable development cannot be carried out if high-yield cutting is carried out, so that the expected market demand and economic benefit cannot be met.
