Description

Device and method for cultivating seedlings of qianqianzhu light matrix Technical Field The invention relates to the technical field of seedling raising of a bamboo, in particular to a device and a method for raising seedlings of a light substrate of a pteridophyte. Background The qiongqiong is a special rare ornamental and craft bamboo species in southwest areas of China, and the bamboo stalk sections of the qiongqiong are enlarged, have unique forms and have extremely high ecological, economic and ornamental values. However, the natural propagation rate of the bamboo is low, the seed setting period is long and unstable, so that the bamboo whip seedling culture becomes a main mode of large-scale propagation and cultivation. Traditional bamboo rhizome of the celtis is mostly planted in a field directly or in a simple container. Although these methods have certain effects, the following technical bottlenecks generally exist: 1. Fragile bamboo whips, especially flagella (growing points), are easily damaged in the seedling raising and transplanting processes, so that the transplanting survival rate is low, and the seedling raising efficiency and the forestation effect are seriously affected. 2. The traditional seedling raising mode cannot apply controllable stress, so that the growth rhythm of bamboo whips cannot be actively regulated, the newly-grown bamboo whips are often weak, the storage and raising capacity is poor, the germination quantity of lateral roots is small, the activation rate of lateral buds is low, and the quality of nursery seedlings cannot be guaranteed. 3. Most of the existing seedling raising containers are vertical plastic pots or nutrition bowls, are seriously inconsistent with biological characteristics of horizontal growth of bamboo whips, lack of guidance aiming at the horizontal growth characteristics of the bamboo whips, cannot control the growth direction of the bamboo whips, lead the bamboo whips to randomly grow in the containers, form a packing phenomenon, and lead to low consistency of nursery seedlings. In summary, the existing method for culturing bamboo seedlings is still in a stage of low transplanting survival rate, unable guarantee of the quality of the nursery seedlings and low consistency of the nursery seedlings, so how to improve transplanting survival rate, guarantee the quality of the nursery seedlings and improve consistency of the nursery seedlings is a problem to be solved urgently in the technical field.
