As can be seen from Table 1, the Cistanche seed granules prepared in the examples of the present invention have significantly higher compressive strength and seed percentage than the seed granules prepared in Comparative Example 1 and Comparative Example 2; the seed granules prepared in the examples of the present invention The breakage rate was 0, indicating that adding viscose to the seed granules could ensure the integrity of the seed granules during packaging, transportation and storage.

Experimental example 2

Adopt the method of digging at random sampling points in the inoculation ditch (after inoculation in spring, in mid-to-early November, before the soil is frozen, dig at random points in the inoculation ditch, carefully observe the parasitism of Cistanche in the inoculation ditch at the digging point, if the host root Cistanche is parasitized and significantly enlarged, it is regarded as parasitic, if there is no enlarged or tumor-like parasite, it is regarded as no parasitic), the parasitic rate of planting Cistanche in the detection examples 1～10 and comparative examples 1～4, the results are shown in the table 2.

Table 2

Among them, the parasitic rate % of the year = (parasitic sample points in the current year/number of test sample points) × 100%. As can be seen from Table 2, the amount of seed used in the examples of the present invention is significantly less than that of comparative example 3, and the annual parasitic rate of Cistanche deserticola in Examples 1 to 10 is significantly higher than that in Comparative Examples 1 to 4. The parasitic rate shows that the prepared Cistanche seed granules and the Cistanche preparation method in the embodiments of the present invention can reduce the amount of seeds used, shorten the parasitic time, and improve the parasitic rate.

From the results of the parasitic rate of the current year in Example 7 and Comparative Example 4, it can be seen that the root-promoting agent added with compound bacteria can significantly improve the parasitic rate of Cistanche seeds in the same year, indicating that the compound bacteria promote the release of metabolites from the host root system, and then promote the growth of the haustoria of Cistanche. formed, increasing the parasitic rate.

The present invention has been described above in conjunction with preferred embodiments, but these embodiments are only exemplary and serve as illustrations only. On this basis, various replacements and improvements can be made to the present invention, all of which fall within the protection scope of the present invention.
