Ginger softening cultivation is based on the normal cultivation of ginger, increasing planting density, strengthening measures to reduce the temperature of the shade, so as to achieve the purpose of harvesting ginger. The ginger harvested in this way not only has a long harvest period and high yield, but also has a fresh and crisp texture, a thin thin section and a fragrant ginger flavor when consumed. First, the election, selection. We did not plant any fertile soil for ginger for three consecutive years. Choose fresh ginger blocks with large blocks, many sprouts and no pests and diseases. Prepare 300 kilograms of ginger per acre. Second, ginger seed processing. First soak ginger seeds in 40% formalin 100-fold solution for 30 minutes, then sew 3-6 hours in sacks, then dry for 2 days, and flip 1 time in the morning and in the evening. Then stack in the house for 4 days. Maintain the temperature at 15°C. °C. This repeated drying, piled three times, is conducive to the germination of ginger. Third, germination. The air-dried wheat hull husks were sprayed with 1% lime water (humidity 70%), and 10 cm thick was placed on the floor of the shed as a litter. After the last ginger seeding, the ginger seed is placed on the litter when the ginger seed is still hot, and is layered one by one. The stack height is about 1 meter. The top layer is covered with 5 cm thick clean straw and then covered. Plastic film or plastic film, the temperature is maintained at about 20 °C, humidity is about 75%, light and germination. When the ginger bud grows to 1 cm, it can be sown and colonized. Fourth, colonization. The germinating ginger seeds are cut into pieces, leaving 2-3 buds in each piece. After cutting, the incisions are sterilized with fresh grass and wood ash, and then soil preparation is done. Mushi Shijia 5,000 kg of common manure is used. Do 1 meter wide radon, and then cover the film, the local temperature stability when planted above 15 °C. 50 cm spacing, planting 15 cm planting trenches, each planting 2 rows. When planting, the tip of the bud is facing south, and the depth is flush with the surface of the bud, then the warm water is sprayed. After the water penetrates, it is covered with a thin layer of fine sand. The tip of the bud is covered with ginger, and then the moisture of the film is kept moist to promote Buds grow. Fifth, field management. Control the surface temperature above 15°C before emergence, and apply sunshade against strong light after emergence. When Jiang Miao grows three lateral branches, Mu recovers 50% of large manure 1000 kg and urea 10 kg. The stems and leaves grow vigorously once every 20 days. Six, pest control. The disease is mainly Jiangyan, which can be used to disinfect ginger block with 200 times liquid of compound ginger radix. The initial stage of the disease is to irrigate the roots with compound ginger radix 200 times every 10 days, and the amount of liquid medicine per mu is 300 kilos. The pests mainly consisted of ginger borers and ground tigers. They were able to spray 90% of trichlorfon 800 times once every 10 days. Seven, softening measures. After each application of fertilizer, ginger roots were used to prevent lodging and promote ginger softening. After 3-4 times of earth-cultivation, ginger roots gradually became ginger ridges. Before the advent of the hot season, shade awnings were erected on the ginger ridges and covered with shade nets to prevent direct irradiation of ginger seedlings with strong light, which could cool and moisturize and play a role in sun protection and softening. Softened cultivated ginger should not be harvested and only ginger can be harvested. It is generally planted in April and can be harvested in August. It can be harvested until the end of October. It produces about 3,000 kilograms of tender ginger.
Freeze Dried process is a method to freeze the dry liquid materials into solid and use the sublimation properties of ice under low temperature and pressure to dehydrate the materials and achieve the purpose of drying. Freeze-drying technology first appeared in the space field, and it is known to all that the space food has a high quality requirement, which is designed to meet the needs of the astronauts in space for the nutrition of fruits and vegetables. Because freeze-drying technology not only let the color, aroma, taste, nutrition of the food itself, but also make food more convenient to carry and transport. With the development of economy, freeze-drying technology has been applied to daily food processing, so the lyophilization process is also called aerospace food technology.
Freeze dried food is to use rapid freezing, vacuum dehydration method of ice, preserved the original color, aroma, taste, nutrition, and the appearance of the original material, the water content of only about 5%, because of the particularity of its craft, by freezing to break the cell wall, so crispy, nutrition, easy absorption
