Soilless culture substrate suitable for seedling breeding of ixeris chinensis and preparation method of soilless culture substrate

Abstract

The invention belongs to the technical field of ixeris chinensis seedling breeding, and discloses a soilless culture substrate suitable for seedling breeding of ixeris chinensis and a preparation method of the soilless culture substrate. The soilless culture substrate suitable for seedling breeding of ixeris chinensis consists of peat, sawdust and river sand according to a volume ratio of 1:1:1. The seedling emergence rate of the seedlings bred by using the soilless culture substrate provided by the invention is 77.5%; the sound seedling index is 0.099; after 25 days from germination, the largest plant height is 8.36cm; after 25 days from sowing, the root length is 8.63cm; after 25 days from sowing, the stem thickness is 0.149 cm; and after 25 days from sowing, the root-shoot ratio is 0.66.

Description

Technical field [0001] The invention belongs to the technical field of sorrel seedlings, in particular to a soilless culture substrate suitable for sorrel seedlings and a preparation method thereof. Background technique [0002] Ixeris chinensis (Ixeris chinensis) is a perennial herb belonging to the genus Asteraceae in the Compositae family. It has strong adaptability and is a common wild vegetable in arid areas in the north. The folk edible sorrel has a history of more than 2,000 years. The whole plant can be used as medicine. It can clear away heat and detoxify, promote blood circulation and drain pus, and treat appendicitis, enteritis, dysentery, sore furuncle pain and swelling. Therefore, Sorrel is a typical medicinal and edible plant. However, there is still a lack of systematic research on the industrial cultivation technology of Sorrel, especially the soilless cultivation substrate formula of Sorrel. Peat is the most common soilless culture substrate. The physicochemi...

AI Technical Summary

Problems solved by technology

[0003] In summary, the existing problems in the prior art are: no special research on the compound matrix formula for the industrialized seedling cultivation of A. chinensis, resulting in the problem of industrialized seedling cultivation in the production of A. chinensis.

There is no research on the effect of sawdust and other common agricultural and forestry wastes as the components of the compound substrate formula for the cultivation of Cicada chinensis seedlings, and a more suitable cost-effective special substrate formula for Cicada cicadas is urgently needed to break through
