First, choose the best species In our province's onion producing area, we can choose purple star, purple jade, new red star and other red and purple skin varieties. These varieties have the characteristics of strong spicy taste, high yield, high quality, and suitable for export. These varieties are generally produced in 5000 mu. In kilograms, the productive capacity of the high-yield plots reached more than 7,500 kilograms. Second, seedbed preparation Seedbed soil should be selected loose, fertile, strong water retention, 2-3 years have not been planted onion, garlic vegetable plots. Each acre of Daejeon needs about 35 square meters of seedbed area, with a seed quantity of 0.5 kg. Apply enough base fertilizer before sowing, then plowing, fine soil preparation, make 1.5-2 meters wide rake, irrigated, ready to broadcast. Third, the appropriate sowing Early and late sowing date directly affects the size of the seedlings, which ultimately affects the onion yield. In early sowing, the growth period of seedlings is prolonged, resulting in excessively large nutrient areas, and seedlings are prone to convulsions; in late sowing, the seedlings are weak and the cold resistance is low, and it is easy to die in winter. Therefore, to achieve high yields, you must master the best sowing time. According to the experience of vegetable farmers, the most appropriate sowing date in the middle of the province's vegetable areas is appropriate 3 days before and after the white dew (in early September). The use of dry seed sowing, covering a thin layer of fine soil after sowing, it is appropriate to not see the seeds. After covering the soil, 33% of the weeds can be sprayed with 100 ml per acre seedbed to prevent weeds in the seedbed. IV. Seedling management The focus of seedling management is to cultivate strong seedlings as the goal. After sowing, cover a layer of wheat straw on the surface of the bowl, which is good for moisturizing, preventing high temperature and rain, and keeping the soil moist before emergence. When about 60% of the seedlings are grown on the seedbed, the covering can be removed. The weather is sprinkled in time to prevent the seedbed from being hardened, and 1% urea can be topdressed in combination with watering to cultivate age-appropriate seedlings through fertilizer and water regulation. It is necessary to prevent the seedlings from growing too large, causing early convulsions, but also to avoid the delicate growth of seedlings, affecting the winter. Generally, onion seedlings can be planted when they reach 4 true leaves, 20-25 cm in plant height, and 6-7 mm in sheath diameter. V. Transplanting at the right time Planting should be transplanted according to the size of onion seedlings so that their growth is consistent, and large seedlings with a sheath diameter of more than 8 mm and weak seedlings and diseased seedlings with a diameter of less than 3 mm are excluded. Colonization is generally completed from the end of October to the beginning of November, and requires daily average temperature to be planted at 4°C-5°C. It takes about 30 days for the onion to regenerate from the time of colonization, so it is imperative to promote the growth of its roots well before the onset of cold, and to prevent the freezing of the soil and cause the dead seedlings. The planting density generally requires 20,000 acres per plant, spaced 20 centimeters apart, 15 centimeters of plant spacing, and the depth of planting is not to bury the quadrants as well. After planting watering, to promote the survival of onion seedlings, avoid flood irrigation, resulting in soil compaction.
Fruit Powder
Fruit powder is made from 6-7 mature and fig or fig dried fruit by raw material processing, squeezing juice, filtering, clarifying, concentrating, spray drying, cooling, packaging and other steps.
Key points of production process:
Selection of raw materials: select 6-7 mature and fresh figs or dried figs. Raw material treatment and pressing for juice: wash the raw materials, add materials according to the proportion of 1kg water plus 1kg fruit, or 1kg dried fruit plus 5kg water, put them into a stainless steel pot, heat them to 85-90 ℃, keep them for 20-30 minutes, then stop heating, stand for 24 hours, and press for juice. Filtration and clarification: it is filtered by a screen filter, and then natural clarification or enzyme clarification. concentrate; Atmospheric pressure concentration and vacuum concentration can be adopted. It is concentrated under normal pressure in a stainless steel double-layer pot, and the heating steam pressure is 2.5kg/cm2. In the concentration process, pay attention to stirring, accelerate water evaporation, prevent coking, and concentrate to make the solid reach 28%. Each concentration should not be fed too much, and the time should be 40 minutes. Vacuum concentration, concentration under reduced pressure and lower temperature. Heating, steam pressure 1.5kg/cm2, temperature 50 ℃.
For Example: Blueberry Juice Powder
In addition to conventional sugar, acid and VC, blueberry fruit is rich in VE, VA, VB, SOD, arbutin, protein, Anthocyanin, edible fiber and mineral elements such as K, Fe, Zn and ca. According to the analysis and determination of 14 varieties of blueberry fruits introduced from the United States, the content of anthocyanin pigment per 100 grams of blueberry fresh fruits is as high as 163 mg, protein 400-700 mg, fat 500-600 mg, carbohydrate 12.3-15.3 mg, vitamin A as high as 81-100 international units, vitamin E 2.7-9.5 micrograms and sod5.39 international units. Vitamins are higher than other fruits. Trace elements are also high, with 220-920 micrograms of calcium, 98-274 micrograms of phosphorus, 114-249 micrograms of magnesium, 2.1-4.3 micrograms of zinc, 7.6-30.0 micrograms of iron, 0.8-1.2 micrograms of germanium and 2.0-3.2 micrograms of copper per gram of fresh fruit.
It is precisely because blueberry fruit is rich in nutrients. It is a nutritional and health fruit with high amino acids, high zinc, high calcium, high iron, high copper and high vitamins. It not only has good nutrition and health care function, but also has the functions of preventing brain nerve aging, strengthening heart, anti-cancer, softening blood vessels, enhancing human immunity and so on.
Health care function
Blueberries can delay memory decline and prevent heart disease, so they are regarded as super fruits. The US daily health news reported that recent research has added a good reputation to super fruit. Eating more blueberries or drinking blueberry juice can help prevent colon cancer.
Blueberries contain a lot of purple components, anthocyanins.
Blueberry fruit can significantly enhance vision and eliminate eye fatigue; Nourish skin; Delaying brain nerve aging; It has therapeutic effect on capillary disease caused by diabetes. Enhance cardiac function; Prevention of Alzheimer's disease and many other medicinal values.
Anthocyanins in blueberry fruit are very powerful antioxidants, which can help prevent the formation of plaque in arteries and a variety of cancers (folic acid prevents cervical cancer, etc.), reduce the possibility of cancer, reduce heart disease and delay aging.

Spray drying: high pressure spray equipment was used to spray the dried fig juice concentrate. The feeding temperature was 50-60 C, the working pressure of the high pressure pump was 180 kg / cm, the dry additive paste powder was added 0.5%, the air inlet temperature was 120 C, and the outlet temperature was 75-78 C. Cooling and packaging: the dried fig powder is cooled quickly, and then packaged and sealed.
The study found that blueberries can play this role because blueberries and other fruits contain a natural compound called pterostilbene, which helps prevent pre cancer damage to the body. Pterostilbene is an Antioxidant and anti-inflammatory agent, which is found in blueberries and blackberries.
