(1) Factory production facilities for virus-free ginger seeds
①Tissue culture room. Establish a tissue culture room and purchase necessary ginger tissue culture detoxification supplies.
② Seedling hardening workshop. Modern seedling hardening workshops require that the temperature, light, and humidity in the workshop can be adjusted at any time as needed to keep the environmental conditions at the best state required for seedling hardening, which is conducive to the cultivation of strong seedlings and greatly improves work efficiency and the survival rate of test tube seedlings.
③ Original insect-proof net room. In order to ensure that the original stock is not reinfected by the virus, it is necessary to establish an insect-proof net room, plant virus-free ginger test tube seedlings, produce the virus-free ginger stock, and conduct virus testing.
④ Original seed nursery and production seed breeding base. The original seed nursery and production seed breeding base are two-level breeding fields, which must ensure disease-free (ginger rot) and virus-free (cucumber mosaic virus (CMV), tobacco mosaic virus (TMV)) production.
(2) Selection of virus-free ginger seed breeding base
The third-level breeding field for virus-free ginger is better located in a mountainous area with an altitude of 850 meters, where the summer is cool and the soil does not accumulate water. , good permeability, not suitable for the occurrence and spread of various viruses. If there are no mountainous conditions, a plot far away from the ginger production field should be selected to establish ginger farming.
(3) Ways to prevent disease and eliminate virus in detoxified ginger
In the case of propagating detoxified ginger, non-toxic and disease-free ginger seeds and disease-free plots should be selected and strictly controlled. Water and fertilizer management. The base fertilizer uses fermented sheep manure and bean cake, and does not use manure and soil fertilizers. The top dressing uses bean cake and chemical fertilizers, and is used in proportion. Use non-polluting water sources for watering, and use water pipes to deliver the water directly to the field. Before aphids, ginger borers, and thrips cause damage, spray pesticides in time to eliminate the transmission routes of bacteria and poisons and ensure disease-free and poison-free production of ginger seeds.
