Abstract

The invention discloses a herba hedyotidis diffusae rooting medium, which is prepared from macroelement compositions, microelement compositions, ferric salt compositions, organic compositions, phytohormone compositions, inositol, saccharose and agar powder. The macroelement compositions are prepared from potassium nitrate, ammonium nitrate, calcium chloride dihydrate, magnesium sulfate heptahydrate and monopotassium phosphate; the microelement compositions are prepared from potassium iodide, boric acid, manganese sulfate tetrahydrate, zinc sulfate heptahydrate, sodium molybdate, copper sulfatepentahydrate and cobalt chloride; the ferric salt compositions are prepared from ferrous sulfate and ethylenediamine tetraacetic acid; the organic compositions are prepared from nicotinic acid, pyridoxine hydrochloride, thiamine hydrochloride and glycine; the phytohormone compositions are prepared from heteroauxin and 6 benzyladenine. Under appropriate conditions, a herba hedyotidis diffusae proliferation seedling slowly grows a developed root system, and the developed root system can ensure the survival rate of herba hedyotidis diffusae transplanting. The invention also discloses a preparation method of the herba hedyotidis diffusae rooting medium. The preparation method of the herba hedyotidis diffusae rooting medium is simple in flow, simple and convenient to operate, and low in preparation cost.

Description

technical field [0001] The invention relates to the technical field of Hedyotis diffusa tissue culture and seedling cultivation, in particular to a rooting medium for Hedyotis diffusa and a preparation method thereof. Background technique [0002] Hedyotis diffusa Willd (Hedyotis diffusa Willd) is an annual herb of Rubiaceae, 15-50cm high, with slender roots, branches and white flowers. The stem is slightly square or flat cylindrical, smooth and glabrous, with many branches from the base. The flowering period is spring, and the seeds are small and yellowish brown. It can be harvested in two seasons a year, spring planting in August and autumn planting in November. It grows in areas with an altitude of 800 meters, and mostly grows in paddy fields, ridges and moist open land. It is mainly distributed in Fujian, Guangdong, Hong Kong, Guangxi, Hainan, Anhui, Yunnan and other areas in China; it tastes bitter, light, and cold in nature. In recent years, it has been found that He...
