Substrate capable of increasing hardening-seedling survival rate of asplenium nidus tissue culture seedlings

Abstract

The invention discloses a substrate capable of increasing the hardening-seedling survival rate of asplenium nidus tissue culture seedlings. The substrate is characterized by comprising leaf mold, peatsoil, crushed straws and perlite, wherein the volume ratio of the leaf mold to the peat soil to the crushed straws to the perlite is 2:2:0.5:0.5. The substrate capable of increasing the hardening-seedling survival rate of the asplenium nidus tissue culture seedlings, which is disclosed by the invention, can increase the hardening-seedling survival rate of the asplenium nidus tissue culture seedlings, increase the germination rate of the asplenium nidus, enhance the adaptability of the asplenium nidus to the outside, shorten the cultivation duration and reduce the planting cost.

Description

technical field [0001] The invention relates to the technical field of bird's nest fern cultivation, in particular to a substrate for improving the survival rate of bird's nest fern tissue culture seedling hardening. Background technique [0002] Bird's nest fern is an epiphytic fern native to southeastern Asia, eastern Australia, Indonesia, India, and eastern Africa. It is also called nest fern, shansu flower, and crown fern. Herbaceous foliage plants. The bird's nest fern has a plump plant shape, bright green leaves, likes a cool environment, is relatively low temperature resistant, has relatively simple maintenance and management, and has strong disease resistance. It can be cultivated continuously for many years. In recent years, it has been used as a high-grade leafy vegetable cultivation and has become an authentic native vegetable . Its young leaves are bright green, and its stir-fried food is crisp and refreshing without bitter taste, so it is very popular among co...

AI Technical Summary

Problems solved by technology

Bird's nest fern mainly reproduces by spores, but the requirements are high. It is difficult to germinate seedlings under natural conditions, and it is not easy to obtain batch seedlings. However, the large-scale production of bird's nest fern can be realized in a short period of time by using plant tissue culture technology. However, the plant tissue culture obtained Because the tissue culture seedlings grow in the tissue culture bottle for a long time, the adaptability to the outside world is low, and the mortality rate after planting is often high, so the requirements for the cultivation medium are relatively high
