At ancient times, people picked up wild fruits, and they found the magic of Goji , The pictograph word "qi" in Chinese character just like a man knelt down at a Goji tree , the left of the character "qi" seems like a tree, and the right like a person bowed down. That means as early as four thousand years ago, people found that Goji can keep fit and role of longevity ,Goji has magic power to people`s life.

Second, the cultivation of disease-free seedlings 1. Seed treatment: In order to prevent seed virus infected virus disease, the seeds can be soaked in 10% sodium phosphate solution for 20 to 30 minutes, or soaked with formalin 300 times for 30 minutes , Or soak for 20 minutes with 1% potassium permanganate solution, remove and wash after soaking in fresh water for 10 hours, then wrap the treated seeds with a damp cloth and put them under 25～30°C for germination. Rinse once and after 5 to 5 days, 50% of seeds can be sown.
2. sowing: per acre of sweet peppers need seedbed 10 square meters, the garden soil and decomposed organic fertilizer mixed at a ratio of 6:4, per cubic meter of mixed soil also need to add 10 to 15 kg of chicken manure, superphosphate 2 Kilograms, after preparing the nutritious soil, 2/3 of them are laid on a seedbed, irrigated with water, and the seed is evenly spread on the seedbed, and then the remaining 1/3 bed soil is placed on the seed, and the bed is covered with a layer after sowing. Mulch to keep bed soil moist. In order to prevent seedling disease, the seedbed was soaked with formalin diluted before sowing.
3. Seedling management after sowing: After sowing, keep temperature 28 ~ 30 °C, night temperature 18 ~ 20 °C; seedlings uncovered after the timely removal of the film, the seedlings to master the daily temperature 25 ~ 27 °C, such as bed see Dry water can be used for watering cans; when the cotyledon flattened at the top, the pests, weak seedlings, mutants, and over-seedlings were removed; the nutrient area of ​​the seedlings was expanded to thrive when the seedlings had 2 to 3 true leaves. To separate seedlings in time. Seedling stage for the promotion of seedling growth, during this period, can be sprayed with 0.05 ~ 0.1% zinc sulfate solution, can delay the occurrence of virus disease, or spray 1 or 2 times in the seedling stage of the disease to prevent the virus 2 The occurrence of the disease. Or use NS-83 increasing agent 50 times, spray 15 days before planting, can induce green pepper and increase virus production. One week before planting, one small water was poured, and two days later, seedlings were planted to facilitate rooting. When the seedlings grow to 18-20 cm and there are 10 true leaves, they can be planted.
Third, colonization 1. Site preparation fertilization: Combine arable land with 5,000 kg of crushed manure per acre, or 1000 kg of puffed chicken manure. The green pepper roots are not drought tolerant, and they are not resistant to soiling. The requirements for site preparation are relatively strict, and fine soil preparation should be performed before planting. It is generally made into a width of 160 cm. It is 25 centimeters high and 20 centimeters wide.
2. Colonization: When planting, each row was planted with 2 rows. According to the 40 cm spacing, the water level was adjusted by digging holes on the loquat, and 1,800 plants were planted per acre. The depth of the colonization was appropriate for the level of the ground and the cotyledon.
IV. Field Management 1. Watering: Pour water after planting to ease seedlings. After the results, it is possible to water according to the season, weather conditions and growth, and to keep the soil moist. Usually 5 to 7 days, 1 water, water should not be too large.
2. Top dressing: top dressing should be mastered with average fertilization, and the principle of less application of ground facilities. Usually 15 to 20 days, a compound fertilizer is applied at a single point, and 20 kg of fertilization is used for mu.
3.Temperature and light regulation: The temperature is controlled at 25～30°C during the day, the maximum is not more than 32°C, the minimum is not less than 20°C, and the nighttime control temperature is 16～18°C. In the summer high temperature period, shading nets should be used to cool the shading, and in winter, continuous cloudy snow weather should be temporarily warmed and filled with light, and the snow should be washed and washed to increase the light transmittance.
4. Pruning hanging vines: Each plant is selected to stay 2 to 3 main branches, buds and buds of the base side of the buds in a timely manner to erase, from the beginning of the fourth quarter to stay in the pepper, the main branch results, after the timely removal of lateral branches, the central branch The fruit can be picked up after leaving one fruit, and 2 to 3 shoots per plant always grow upward. Generally do not earth, each main branch can be fixed with an anti-aging plastic rope.
5. Thinning and thinning fruit: During the growth period, thinning and fruit thinning should be carried out in time to ensure that no more than 6 results are obtained at the same time in each plant, so as to facilitate fruit enlargement with sufficient nutrients. In order to increase the yield and promote the growth of the early plants, the pepper must be removed in time.
V. Disease and Pest Control Diseases of the bell pepper are mainly virus diseases and epidemics. Virus disease can be controlled by spraying 20% ​​of the virus A WP 500 times; the disease can be controlled by 72.2% Prec or 50% of AA. The main pests of color pepper are aphids and cabbage caterpillar which can be controlled by 10% imidacloprid and 1.8% avermectin spray.
6. Harvested fruits must be harvested in time after they stop expanding and turning.
A large-scale efficient cultivation technique of greenhouse pepper
1. Variety selection Choose varieties that are resistant to low temperature, weak light, strong growth potential, high yield, and good merchandise, such as red crystal, white jade, and Mazurka.
