Production technology of export ginger sprouts

The export ginger bud is similar to the conventional ginger cultivation technique, the dense seedling type "Xiao Ginger" with many branches is selected in the variety, and the sowing density is 10000 plants per mu, and the cultivation management techniques are mainly as follows: applying base fertilizer, topdressing and watering as soon as possible to promote the early branching and growth of ginger and pay attention to shading at the same time. The production of ginger sprouts can be carried out from the long seedling of ginger to the harvest time of ginger. To soften the production of ginger sprouts, we should focus on the following links:

(1) to build a training ground. You can make use of spare houses, warehouses or reconstructed nurseries such as greenhouses and solar greenhouses. The site is equipped with bud nursery bed and heating equipment. The nursery bed is made of cement board or brick into a multi-layer support form, heated by underground fire or electric heating, and air vents are left on one side or around the place. The greenhouse cultivation rack is equipped with 5-6 layers, each layer is 100 cm wide and the distance between layers is 50-60 cm. The layer length depends on the length of the greenhouse. If cultivated in the house, the height depends on the height of the house.

(2) the key points of cultivating techniques. To choose fat, disease-and insect-free ginger pieces, break into 70 grams of ginger seeds. The buds are arranged upward and densely arranged, each square meter of ginger seeds 20 to 30 kilograms, ginger pieces covered with 1 cm thick fine sand, ginger pieces covered with 3 cm thick fine sand, spray the right amount of water. The temperature before budding was kept at 23: 25 ℃, and ginger buds germinated 5-6 days after heating. 7-10 days before ginger sprouting, appropriate amount of water was sprayed according to the dry and wet condition of bed soil, and a small amount of nitrogen, phosphorus and potassium quick-acting fertilizer was sprayed in water at a concentration of less than 1%. Maintain 80% to 90% humidity in the breeding site. The temperature was kept at 2830 ℃ from budding to 30 cm high, and the bed temperature was kept at 25 ℃ 10 days before seedling collection. It should be properly ventilated after budding, especially a few days before budding.

(3) timely harvest of ginger sprouts. Ginger seeds can be harvested when they go to bed for 45 to 50 days and most of the buds grow to 30 cm high. Take out the ginger cubes with a tool, then break off the ginger seedlings, remove the fibrous roots from the sprouts, and rinse clean. The terminal bud can be cut off if the bud is more than 30 cm.

(4) processing. The ginger buds (seedlings) were cut off by using a cylindrical ring knife to cut the ginger buds (seedlings) into the ginger block, and the semi-finished products were made into a rhizome with a diameter of 1 cm, a length of 2.5 cm and a total length of 15 cm, which was cured with acetic acid salt water.
