A kind of soilless green seedling raising method of licorice

Abstract

The invention relates to a soilless green seedling raising method of licorice, comprising the following steps: making a seedbed, seed germination treatment, sowing seedlings, seedling management, seedling digging and transplanting, wherein codonopsis waste particles are introduced into the mixed matrix poured into the seedbed, The preparation method of the Codonopsis pilosula waste granules is to collect the discarded Codonopsis pilosula leaves and stems after harvesting, continue drying at about 60 degrees Celsius, and directly crush and sieve after drying to obtain particles of about 2 mm. The invention improves the germination rate of licorice seeds, reduces the incidence of disease, and at the same time obviously improves the adult plant rate of seedlings, is suitable for the growth of licorice seedlings, increases the growth period and the survival rate after transplanting, and the obtained licorice seedlings can grow in a field for 2 years after transplanting When left and right harvesting, the yield of fresh roots per mu is about 1700 kg, which is significantly higher than the level of yield per mu of existing licorice seedlings, which greatly improves production efficiency and reduces costs, and provides strong support for the large-scale development of licorice industry.

Description

technical field [0001] The invention relates to the technical field of agricultural economic crop breeding, in particular to a soilless green seedling raising method for licorice. Background technique [0002] Licorice is a perennial herbaceous leguminous plant, and wild licorice is a national second-class endangered species. Licorice root or rhizome is used as medicine. It is a kind of tonic Chinese herbal medicine. Licorice has strong tolerance and adaptability to the environment. In my country, it is mainly distributed in Xinjiang, Inner Mongolia, Ningxia, Gansu, Shanxi and other places; while artificially planted licorice is mainly produced in the Hexi Corridor of Xinjiang, Inner Mongolia, and Gansu, and around Longxi. parts of Ningxia. [0003] Due to random digging, wild licorice resources are decreasing year by year, but with the development of society, the market demand for licorice continues to increase, and the artificial planting of licorice has been strongly emp...

Problems solved by technology

However, it has been found in practice that simple application of the existing soilless seedling cultivation methods cannot obtain robust licorice seedlings. The reason is that the nutrients required for the growth of seedlings in soilless cultivation all come from the nutrient solution, but for the nutrient solution of authentic Chinese herbal medicine The research and development is not perfect, and the nutrients required by various Chinese herbal medicines are not the same. Some key elements cannot be provided by the existing nutrient solution. Without these key elements, the seedlings of Chinese herbal medicines will not grow well. The core point is these key elements At present, there are not many research results on what substance or combination of substances. Therefore, it is not possible to successfully obtain robust licorice seedlings by simply using soilless seedling technology. solve the above problems
