In recent years, in order to expand the export of ginger, a whole set of ginger bud production supporting technologies have been concluded in various regions, which have achieved high economic benefits. Ginger buds are divided into ordinary ginger buds and softened ginger buds.
The production techniques of ordinary ginger buds are similar to those of conventional ginger cultivation techniques, but they are also different. The following points should be mastered: 1 To use more dense seedling varieties with branches, so that the branches of ginger are more, and the number of buds is also large. Ginger buds can be used when there are many more, to facilitate more products; 2 use smaller ginger seeds sowing, lower investment, increase the utilization of ginger, and the smaller number of ginger branches will not be too little, does not affect the ginger bud Number: 3 Increase the seeding density, increase the number of plants per unit area, increase the number of branches per unit area, and also increase the number of buds, which is conducive to more production of ginger buds; 4 pay attention to strengthen management, increase basal fertilizer, early fertilizer Watering promotes early branching and growth of ginger, and at the same time, attention is paid to plugging the ginger.
Ginger bud production generally can be started in the ginger long-term seedlings, roots and stems have not fully expanded until the ginger harvest can be carried out. The specific method is: using a tubular ring knife to cover the ginger buds (seedlings) to cut the ginger buds (seedlings) into the ginger block middle cutter to make a root diameter of 1 cm, a length of 2.5 to 5 cm, the roots together with the total length of ginger A 15 cm semi-finished product is finished after being salted with acetate. Generally three: a root product length of 3.5-5 cm; secondary product root length 3 to 3.5 cm; third product root length 2.5 to 3 cm.
The cultivation techniques of softening ginger buds are as follows: Softening Ginger buds are new products that are cultivated in the absence of light. They have the characteristics of tenderness, freshness, fragrantness and brittleness, and are mainly used for foreign exchange for export. To soften ginger bud production, we must focus on the following aspects:
(1) Build a cultivation site. You can use incubators that are converted from empty houses, warehouses, air-raid shelters or greenhouses, sheds, and solar greenhouses. The site needs to be equipped with germination seedbeds, temperature-increasing equipment, and ventilation outlets. The seedbed can be in the form of a multi-layered support frame made of cement or brick, and can be heated by using an underground fire or electric heating line, leaving a ventilation outlet on one side or around the site.
(2) Nurturing technology must be supported. To use fat, no pests, ginger pieces. Germination of ginger seeds will be piled up, about 1 meter high, spray the right amount of water, cover the sand insulation and moisture, maintain the heap temperature of 25 °C. After the majority of buds germinate but not rooted, the buds were selected and the buds were grading and graded according to the bud size. Then plant the seed on a 4 to 5 cm thick sand bed, taking care that the buds line up and then cover the 5 cm fine sand. The use of species per mu is about 250-350 kg. Ginger was sprayed with a watering can immediately after going to bed, soaked in bed soil and sprayed a second time after the majority of ginger sprouts were unearthed. About 7 to 10 days before ginger shoots, suitable amount of water is sprayed according to the wet conditions of the bed soil. When water spray moisturizing, according to the growth conditions, a small amount of NPK fertilizer can be dissolved in water, and the concentration should be less than 1%. Maintain 80% - 90% humidity in the cultivation site. The bed temperature was maintained at 25-28°C before and after the ginger shoots were excavated, and the bed temperature was maintained at 25°C for 10 days before picking. Pay attention to proper ventilation during budding, especially before picking.
(3) Harvesting ginger buds should be timely. Ginger goes to bed for 45 to 50 days, and most shoots grow to 30 cm in height and can be harvested. Ginger with a tool out and then plucked ginger seedlings, remove the shoots on the sprouts, rinse it. Shoots more than 30 cm can cut off the top buds.
(4) Appropriate processing. After the buds are removed, if the roots are too thick, the peripheral part can be cut off with a circular knife, and the grading is performed according to the roughness of the roots, and then the ginger seedlings are cut to a total length of 15 cm, and then put in an acetic acid salt water for marinating. After pickling is completed, bundles of 10 can be bundled, cans can be filled, and the reconstituted acetic acid brine can be poured, sealed and packaged for export.
