Method for improving seedling raising propagation coefficient by inducing neosinocalamus bamboo stalk adventitious bud germination

Abstract

The invention relates to the field of asexual seedling raising in agriculture and forestry, in particular to a method for improving the seedling raising propagation coefficient by inducing neosinocalamus bamboo stalk adventitious bud germination. The method comprises the following steps of (1), seedling raising material screening, wherein from February to March of the current year, a mother bamboowith a stalk bud primordium is selected, a bamboo segment containing two bamboo nodes and a complete internode is intercepted, a seedling raising bamboo segment is obtained, and the mother bamboo isselected from one or multiple of the bamboo stalk parts remaining from an annual bamboo bamboo-stump seedling raising and bamboo stalk parts of a 2-3-year-old neosinocalamus cutting orchard and 2-3-year-old tip-broken defective neosinocalamus; (2), seedling raising material treatment, wherein a hole is made in the middle of the bamboo segment, and 50-70 mg/L of an ABT1# rooting powder solution isinjected into a bamboo segment cavity through the hole. According to the method, various bamboo stalk adventitious bud materials can be fully utilized, adventitious buds are induced to germinate, thepropagation coefficient is improved, the seedling raising effect is improved, and a large number of high-quality seedlings are generated; the adventitious bud rooting shooting rate can reach 70% or above.

Description

technical field [0001] The invention relates to the field of asexual seedling cultivation in agriculture and forestry, in particular to a method for inducing the germination of adventitious buds from the bamboo stalks of Sagittarius japonica and improving the reproduction coefficient of seedling cultivation. Background technique [0002] Cizhu (Bambusa affinis) is naturally distributed in the Yangtze River Basin of my country. It is one of the best bamboo species for making paper from bamboo pulp. [0003] There are many ways to raise seedlings of Cizhu, mainly including bamboo seedlings and stalk burying, etc. Based on the different organ parts of Cizhu, it can enrich the reproduction methods and improve the reproduction efficiency. [0004] Publication number is that the Chinese patent document of CN103858650A has announced a kind of cuttage propagation method of Cizhu, comprising the following steps: (1) cuttings are soaked in the ABT2 rooting powder solution that concent...

[0005] Publication No. is that the Chinese patent document of CN108377831A has announced a kind of method for burying seedlings of clumps of bamboos, comprising the following steps: (1) selection and site preparation of nursery: deep plowing, leveling, making ridges to set seedling beds, disinfection, watering Water permeable; (2) selection of bamboo section for raising seedlings: fall new bamboo, get bamboo section, wrap bamboo section, get bamboo section for raising seedlings; Drill holes, inject growth hormone solution, and seal; (4) Seedling cultivation: open a planting ditch on the seedling bed, keep the bamboo section drilled and place it in the planting ditch upwards, cover the soil, compact, pour water, and cover the seedbed with a film; (5) Nursery Land management: After the bamboo seedlings are unearthed, open the film at the germination place, water and keep the soil moist; set up a shade net; remove the film, weeding; The bamboo nodes that have not germinated and branched on the annual clustered bamboo are used as seedling raising materials. The technical defect of this method is that the seedling raising advantages of the germinated bamboo nodes that have germinated and branched are ignored, and the instructions for raising seedlings of 2-3 year old bamboo nodes are lacking.
