Problems solved by technology

However, only the stigma of saffron can be used as medicine. Due to factors such as limited areas suitable for cultivation and harsh conditions, the yield is extremely low and resources are extremely limited, resulting in high prices. It has always been known as "plant gold".
Because saffron cannot reproduce sexually, it can only reproduce asexually through bulbs, and its bulbs degenerate seriously under cultivation conditions, resulting in a serious shortage of germplasm resources.
Since the introduction of the species in my country, the yield of cultivated saffron has always been low, which is far from meeting people's needs.
In recent years, tissue culture technology has been applied to the production of saffron seedlings, which provides a solution to the shortage and degradation of saffron bulbs. However, plant tissue culture is a labor-intensive industry, and the production cost remains high. The production of seedlings is also difficult. only in the experimental stage

Abstract

The invention discloses a planting method for saffron crocus tissue culture micro bulbotubers, and technical service is provided for seedling hardening planting in the later period of saffron crocus plant tissue culture. The planting method for saffron crocus tissue culture micro bulbotubers includes the following steps of seed source preparing, wherein seed selecting and sterilizing are involved; soil preparation, wherein the substeps of planting in a field, applying base fertilizer, disinfecting soil and carrying out furrow opening and ridging are included; planting and observing, wherein two substeps of sowing and observing are included. As the bulbotubers and soil are sterilized and disinfected by adopting multiple disinfecting methods, damage to the tissue culture micro bulbotubers by microorganisms is eliminated or reduced, and the planting survival rate is large; the method of two-time deep ploughing is adopted, and the soil is loosened, which is more beneficial for growth of saffron crocus. The planting method is easy to operate and low in cost, and large-scale industrial production is easier to achieve.

Description

technical field [0001] The invention relates to a method for cultivating Chinese herbal medicines, in particular to a method for planting saffron tissue cultured microbulbs. Background technique [0002] Saffron (Crocus sativus L.), also known as saffron and saffron, is a perennial flower of the genus Crocus in the family Iridaceae, and is also a common spice. It is a native species in Southwest Asia and was first cultivated by the Greeks. It is mainly distributed in Europe, the Mediterranean, and Central Asia. It was introduced into China during the Ming Dynasty, and it was listed as a medicine in the "Compendium of Materia Medica". It is currently cultivated in Jiangsu, Zhejiang, and North China. It is a valuable traditional Chinese medicine. material. Spices and main natural pigments such as saffron, saffron picroside and saffron aldehyde can be extracted from its stigma. Saffron is an active ingredient with significant curative effect on coronary heart disease. Small,...
