1. Brain-strengthening and intelligence-improving: Rubus has the function of brain-strengthening and intelligence-improving, and the antioxidant contained in it can effectively prevent the brain from being damaged by free radicals, improve the blood supply and oxygen supply to the brain, thus achieving the function of brain-strengthening and intelligence-improving.
2. beauty beauty: Flavonoids contained in raspberries not only have antibacterial, anti-inflammatory, antihypertensive and antiallergic effects, but also have remarkable skills in skin care and beauty. These substances can improve the blood circulation of skin, enhance the elasticity of skin capillaries and promote the regeneration of skin cells, thus playing the role of beauty beauty.
3. Prevention and treatment of cancer: Free radicals are raging in the body like thugs, destroying tissues and cells and changing the molecular structure of DNA, thus leading to cancer. Rubus contains a very healthy component-anthocyanin, which has the function of scavenging free radicals and preventing cancer, so raspberry is of great significance for the prevention and treatment of cancer.
4. Strengthening yang and softening hardness: The active ingredients contained in raspberry can improve the blood circulation of penis, improve the excitability of sexual nerves and make weak penis full of vitality, so raspberry has a significant effect on preventing and treating male erectile dysfunction and frigidity.
5. Anti-aging: D- galactose aging model was used to observe the effects of raspberry on learning and memory ability and brain monoamine oxidase B in mice. The results show that raspberry can obviously shorten the swimming latency of aging mice and reduce the activity of MAO-B, which shows that raspberry can improve learning ability and delay aging.
Planting techniques of raspberry
1. Garden construction: choose the plot which is sheltered from the wind and sun, with loose soil, high organic matter content and wet soil and is not suitable for water accumulation. Before the garden is built, it should be ploughed and leveled, and farmyard manure should be applied at 2000 ~ 4000 kg/mu. The planting method is strip, the row spacing is 2m, the spacing between plants is 0.4 ~ 0.8m The specifications of planting holes are 30 × 30 × 30cm, and attention should be paid to protecting the basic buds from damage when planting seedlings. After planting, the stubble should be leveled in time, and the stubble should be about 20 cm, and 2 ~ 3 plants should be planted in each hole to achieve the goal of high yield as soon as possible.
2. Soil preparation: When planting raspberries, select the slightly acidic gentle slope land with deep soil layer, loose fertility and good drainage, turn over the soil deeply, and transplant raspberries according to the row spacing of 50 cm× 100 cm or 100 cm. Apply sufficient base fertilizer before transplanting, and apply farmyard manure to each plant.
3. Management: During the growth period of raspberries, soil loosening and weeding should be combined, and topdressing should be carried out 2-3 times a year, with nitrogen fertilizer as the main fertilizer and appropriate amount of phosphorus and potassium fertilizer. Apply seedling fertilizer in March, flower fertilizer in April, overwintering fertilizer 5438+065438+ 10 month in June, apply 1500 ~ 2000 kg of human excrement and urine per mu, and pay attention to watering in summer and autumn drought. Weeding twice a year in May-June and August-September can reduce the consumption of nutrients and water by weeds and promote the robust growth of raspberry trees.
4. Bud picking: When the new branches of raspberry have lateral branches in April-May, the top buds are picked to promote the growth of lateral branches, and at the same time, the core of lateral branches is removed to promote the secondary lateral branches and the branches are leafy, so as to increase the fruiting mother branches in the second year and improve the yield. A post should be erected next to each plant in the fruiting period to prevent lodging.
5. Bracket: Raspberry branches are soft and tend to droop to the ground, or prone to lodging in the wind, affecting yield and quality. Therefore, a bracket is set in the garden, and the biennial branches are tied to the frame, so that the branches receive light evenly and maintain good permeability in the garden.
6. Fertilizer and water: 2,000-3,000 kilograms of farmyard manure can be applied per mu in autumn every year, and topdressing should be done once in flowering and fruiting period to increase fruit yield and promote fruit expansion. Topdressing should be based on available nitrogen fertilizer, and urea 10 ~ 15 kg should be applied once per mu. At the same time, apply borax 1kg and zinc sulfate 1kg per mu to protect flowers and fruits. Do a good job of drainage and irrigation, water in time in case of drought, and keep the soil moist. In case of rainstorm, the accumulated water should be removed in time to prevent falling flowers and fruits.
7. Pruning: In spring, the dry part at the top of biennial branches should be cut off in time, so that the remaining branches can produce strong and robust fruiting branches. 7-8 biennial branches are reserved for sparse branches with dense base and diseases and insect pests, and the density is reasonable, which is beneficial to ventilation and light transmission and ensures high and stable yield. After fruit picking, biennial branches should be cut off, tillers and over-dense base branches should be thinned out, and the total number of branches in the garden should be controlled.
8. Harvest: The harvest time of raspberries is from mid-May to early June. At this time, the fruit is completely green and has not yet turned red and matured. Harvest in batches. After harvesting, remove impurities such as stems, leaves and receptacle, then put them in boiling water for 2-3 minutes, take them out, and then spread or dry them. The finished product is better with complete particles, solid yellow-green, sour and sessile leaves.
