Bell pepper is rich in nutrients, high in vitamin content, and has a variety of delicious flavors. Green fruit can be used for many dishes, and the nutritional value of the old fruit is higher. The product is resistant to storage and transportation, long harvesting period, and is widely cultivated throughout the country. Using this feature, after a few years of research, a set of high-yield cultivation techniques was postponed in the greenhouse. First, the selection of varieties in the greenhouse postponed cultivation to use thick flesh, disease resistance of the late-maturing varieties. Such as eggplant door, Nongda 40, Jilin three ribs and so on. Second, nurturing strong seedlings and strong seedlings are the basic conditions for high yields. Strong seedlings standard: seedling height 17 to 21 cm, stem thick 0.3 cm. With 10 to 14 leaves, the top buds, calendar seedling age 80 to 90 days. The key to nurturing strong seedlings is to increase the temperature and improve the nutritional conditions. To this end, sweet pepper nursery should use nutrient soil secondary seedlings. 1. A nursery. The sowing period should be 80 to 90 days ahead of time (10 cm deep ground temperature stabilized at 12°C or higher) in the local area, and the sowing date should be determined by adding the number of days before emergence. 50% of the soybeans used in the field were soured soil without solanaceous vegetables plus 30% of decomposed horse manure and 20% of high-quality farmyard manure. 300 g of ternary compound fertilizer with nitrogen, phosphorus, and potassium contents of 15% each is applied per cubic meter. After mixing well, spread 8 to 10 cm thick on the surface of the bed, and pour enough water to cool the bottom water. Then cover the soil with a layer of plastic film to warm it. After the seedlings have been excavated, the plastic film can be removed. In order to ensure timely planting. Yangshuo or middle and small shed nursery should be adopted according to local conditions. After the emergence, the temperature was controlled at 23°C to 25°C during the day and 17°C to 15°C at night. Water control must be strictly controlled to prevent leggy. 3 true leaves are seedlings. 2. For secondary seedlings, use 70% of Sonoda soil plus 30% of high-quality fine manure. Each cubic meter of nitrogen, phosphorus, potassium content of 15 ternary compound fertilizer 400 grams. Do nutrition or nutrition nursery. When transplanting seedlings, transplant one or two strains according to the degree of opening of the variety. During the nursery period, it is necessary to use thermostatically controlled water and other measures to achieve balanced growth on the ground and underground and cultivate strong seedlings. One week after transplanting, keep 25°C to 30°C during the day, slow 2O°C to 25°C during daytime, and 17°C to 15°C at night. 10 to 15 days before planting, low-temperature seedlings should be carried out. Third, colonization 1. Fine soil preparation and fertilization. As the sweet peppers are postponed for a long period of growth, the amount of basal fertilizer should be appropriately increased. 667 square meters of high quality manure 6,000 kg, 50 kg of diammonium phosphate, 50 kg of cake fat, combined with deep pour. After deep plowing, it is fine. From one side of the ground, it is 50 centimeters wide. Then cover the plastic film on the two sides of 50 cm. Place two sides of the bowl with 6 to 8 centimeters of the outer edge of the bowl, flatten the surface of the bowl and tighten the soil on both sides. 2. Colonization. At the time of colonization, the planting hole is first opened on the pole by 30 to 33 centimeters, then the seedlings with nutrients are planted in the planting hole, covered with a half-buried soil, and the seedlings are irrigated with water. The next day, the seedlings are sealed and pressed around the planting hole. Plastic film. Fourth, open cultivation and management of open field cultivation management to prevent disease and protection of plants. In the summer before the onset of high temperatures, it is necessary to promote the growth of plants, and strive to seal in front of large potatoes, increase the resistance to disease in the hot season. Into the full fruit period, we must strengthen fertilizer and water management and pest control. Leaves the leaves to maintain vitality. After 3 to 4 days after planting, the seedlings were watered once. Afterwards, they were no longer watered and the roots were properly controlled. Prevent long flowers. After the door peppers are seated (that is, the fruit grows to 3 to 4 centimeters in length), they begin to water, and the land cannot see dry cracks. Water once every 7-8 days, and top-dressing with water. 667 square meters of urea 15 kg or 20 kg of diammonium phosphate. It is also possible to spray 0.3% potassium dihydrogen phosphate on the foliage to prevent premature aging. Fifth, do the arch before the first frost, according to the width of 3 meters, the length is not limited to do arch. Make an arch every 1 meter. There is only a center column and no side columns. In the column material can be adapted to local conditions, local materials. Use the remaining wood branches or bamboo cemetery for logging 1.5 meters long, buried 20 centimeters underground and 1.3 meters high. The bamboo pillars were used to make arches on the columns. Six, do a good job before the preparation of the buckle shed Before the frost came 4 to 5 days, we must promptly get the sweet peppers to reach the commodity standards, and sell them nearby. Then 667 square meters topdressing sulfuric acid according to 20 to 25 kg, filling a large water. Seventh, the average temperature of the buckle shed fell to 13°C on the same day. 2 to 3 days before the beginning of the frost, the wind-free weather film was selected on sunny days. Two plastic films were used, and the middle pressure was used to reduce the temperature and adjust the temperature inside the shed. After the buckle film is fixed with a lamination line to prevent the wind from scraping the film. Eight, to strengthen the temperature management should be mainly controlled temperature rise in the early stage, the main insulation in the later period. After the shed, due to the high outside temperature, the top dressing and irrigation were conducted before the shed. To this end, it is necessary to pay attention to cooling and control. The temperature in the booth is controlled at 25°C to 30°C. Appropriate control of growth. In the later period, the outside temperature drops, in order to ensure the normal growth of sweet peppers, thermal insulation measures should be strengthened. During the day, the air should be closed 2 hours before sunset to increase the temperature inside the shelter to prevent the nighttime temperature from falling too much and affecting the growth. Nine, strictly control the roots of sweet pepper water, root group hi wet, afraid of water. To this end, after the shed, a small amount of groundwater shall be used to prevent water shortage and water accumulation. Irrigation should be carried out on a sunny morning and be promptly vented to prevent the occurrence of disease. Ten, prevention and control of pests and diseases sweet pepper delay cultivation, long growth period, improper management will produce a variety of diseases, early ground management, post management, artificial control of disease conditions and the combination of drugs for prevention and treatment. XI. Early harvesting should be timely harvested with the maturity of the fruit. When the greenhouse temperature drops to 5 °C ~ 6 °C, all harvested to prevent frozen fruit. After harvesting, it is preserved by the cylinder storage method and is supplied on the New Year's Day and Spring Festival markets.
Our Goji Powder uses the technique of vacuum freeze. In this method, the most part of the water in the berries is frozen rapidly to make the free water crystallize into solid. Then the absorbed water in the berries is removed through desorption. Finally, the goji berries are pulverized and produced complete goji powder. Our goji powder has the advantages of low water content, good color, plump appearance and high commodity value. It retains more bioactive substances than traditional method and can be used for producing water-soluble solid beverage. The powder is widely used in the production of functional food, beverage, healthy products, which is used as important raw material of beauty products. It is also very useful if used in the tea or also in other foods providing you a natural rich nutritional supplement.
