Cow dung matrix for seedling raising of radices stellariae dichotomae

Abstract

The invention discloses a cow dung matrix for the seedling raising of radices stellariae dichotomae. The matrix is characterized by being prepared from 100 parts of rotten cow dung, 20-30 parts of rural soil, 5-10 parts of vermiculite, 3-5 parts of perlite, 3-5 parts of river sand, 2-5% of macroelements, 0.2-0.4% of trace elements and a moderate amount of water by mixing, wherein the macroelements include mixed ammonium salts, potash fertilizers and organic phosphate fertilizers; the trace elements include magnesium, iron, copper, zinc, manganese, and boric acid; the cow dung is rotten cow dung which is circulatory rotted and dried, and a rotting method is implemented by stacking cow dung, and carrying out full fermentation and degerming on the cow dung in a way of layered depositing and circulatory rotting. The dried rotten cow dung is crushed into particles with a particle size of 2-5mm, then the particles and other components are mixed, and the pH value of the obtained mixture is adjusted, so that a prepared matrix just can meet the budding conditions of radices stellariae dichotomae, thereby improving the budding rate and the survival rate. The matrix disclosed by the invention has the advantages that cow dung is fully rotten in a short time, so that materials for a rotting agent are reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to a seedling-raising substrate of Chinese medicinal materials and a method thereof, belonging to the technical field of soilless cultivation, in particular to a cow dung substrate for seedling-raising of silver bupleurum. Background technique [0002] Silver Bupleurum is the root of the genus Silver Bupleurum in the family Caryophyllaceae, and it is mainly produced in Northwest my country, Inner Mongolia and other places. The original plant grows in dry grasslands and crevices on hillsides. It likes warm or cool climates. It is cold-resistant, light-loving, afraid of waterlogging, and suitable for growth in loose sandy soil. Yin Bupleurum is one of the common Chinese herbal medicines. It is sweet in taste, slightly cold in nature, and returns to the liver and stomach meridian. It has the effect of reducing asthenia heat and clearing dry heat; its shape is cylindrical, with occasional branches, 15-40cm long , 0.5-2.5cm in diamete...

Problems solved by technology

After searching, it is found that there are many reports on cultivating seedlings with cow dung as the substrate. For example, patent CN101041604A discloses a kind of melon and vegetable seedling substrate. , potassium and other elements to prepare a seedling substrate for melons and fruits; patent CN103039336A discloses a seedling substrate for the production of organic selenium-enriched strawberries, and the seedlings of selenium-enriched strawberries are also prepared by raw materials such as cow dung and selenium-containing flax cake Although these methods have solved the problem of cow dung pollution and obtained certain economic and social benefits, however, the coolness of cow dung makes it unsuitable for hot crops, and melons and fruits are hot plants. The quality of the fruit is seriously reduced and the taste is not good

In order to overcome this problem, the present inventor has proposed a kind of cow dung substrate that is used for the seedling cultivation of C. chinensis through experiments and studies, which combines the habit of loose soil and budding at low temperature of C. chinensis, and is decomposed and dried through cow dung. process, so that the prepared substrate is loose and breathable, and the moisture content is suitable for the emergence of silver bupleuri.
