Dendrocalamus minor two-section type rapid propagation seedling culture method

Abstract

The invention discloses a dendrocalamus minor two-section type rapid propagation seedling culture method. According to the method, bamboos planted in separated planting in a strongly growing dendrocalamus minor grove are used as mother bamboos, in the first year, top cutting and germination promotion and side branch trimming are firstly carried out, in the second year, bamboo poles of the upper half parts are taken to be used as cutting slips, in the third year, the bamboo poles of the lower half parts are taken down to be used as cutting slips, cutting slips collected in the two stages are respectively subjected to cuttage into non-woven fabric net bags containing substrates and are placed into a vinyl house for seedling culture, and dendrocalamus minor containing cuttage seedlings are obtained. The seedling culture method provided by the invention has the advantage that the growth condition of the mother bamboos can be easily controlled, the side branch germination of the bamboo joints at the lower part can be promoted, the cutting slips are collected in two stages, resources are sufficiently utilized, the utilization rate of the mother bamboos is improved, the cutting slip quality is high, the rooting time is short, the propagation rate and the cuttage survival rate are high, the culture bamboo seedlings are healthy and strong, meanwhile, the transportation cost can also bereduced, the mountain climbing afforestation is convenient, the peeling cup is not needed during the afforestation, the afforestation speed and the afforestation survival rate can be respectively accelerated and improved, the bamboo seedling recovery is fast after the afforestation, the growth is fast, and the economic benefits are good.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and relates to a two-stage fast-propagation seedling raising method of hanging silk bamboo. Background technique [0002] Diaosi bamboo (Dendrocalamus minor Chia et) is an excellent greening ornamental and timber bamboo species of the genus Bamboo in the Poaceae bamboo subfamily. The height of the pole is 6-8m, the diameter is 3-6cm, the thickness of the bamboo wall is 5-6mm, and the length of the internode is 30-40cm. Diaosi bamboo has thicker bamboo wall and good bamboo properties. It is one of the bamboo species used for high-quality bamboo rafts. It is suitable for weaving various exquisite bamboo wares; Diaosi bamboo has high fiber content and moderate fiber aspect ratio, and is the first-class raw material for papermaking industry; Diaosi bamboo The yield of bamboo shoots is high, the taste of bamboo shoots is delicious and tender, and it is rich in nutrition. It is a ...

Problems solved by technology

[0003] Diaosiba seldom blooms and is not easy to bear fruit, so seedlings are basically not used for breeding seedlings, but seedlings are propagated by vegetative propagation methods, mainly including burying stalks, burying nodes, burying bushes, secondary branch cuttings and tissue culture, among which the tissue culture method technology It is immature, and limited by the weak outdoor stress resistance of young seedlings, it cannot be popularized and applied in production.

The invention of Hui Chaomao et al. "A Method for Rapid Propagation and Raising Seedlings of Bamboo" (Application No.: 200410040564.4) uses the shoots of bamboo poles as propagation materials, and uses the side branches and side buds of the second level and later to take root and bury the seedlings; Wei Jianwen's "Research on Asexual Propagation Technology of Bamboo Seedlings" (Fujian Forestry Science and Technology, Volume 30, 2003, Add 1) adopts the seedling raising method of bamboo cuttings, burying nodes and divisions, wherein the burying method is to cut bamboo poles into single nodes or Double-jointed bamboo sections are placed flat on the seedbed; Tan Hongchao's "Experimental Research on Asexual Propagation of Clustered Bamboo Seedlings" (Bamboo Research Transactions, No. 1, 1994) adopts the method of internode incision and burying stalks and the method of raising bamboo seedlings by division. The seedling raising time is from March to April, and the bare-rooted seedlings are cultivated. The main difference is that the selected propagation materials are different. As a result, the mother bamboo is not strong, the utilization rate is low, the quality of the cuttings is poor, the rooting time is long, and the reproduction rate is low. The survival rate of cuttings is relatively low
