Planting method and nutritional value of raspberry

Raspberries are perennial shrubs. It belongs to clumps, and its branches grow obliquely or lie long for life, generally 3-4 meters long. Its fruit is a berry, and the sweetness and acidity of the fruit is more palatable and nutritious.

Tissue culture seedling raspberry

Raspberries are known as golden fruits, also known as raspberries. Beijingers are commonly known as Topu, which is similar to strawberries, but the fruit is sour, sweet and delicious and has a peculiar flavor. The fruit of raspberry is actually aggregate berry, which is formed by a tight arrangement of multi-layer ripe drupes. The fruit is tender and juicy, pleasant in color and rich in nutrition. it is the third generation of small berries popular in the world and is known as the golden fruit in the international market. According to traditional Chinese medicine, raspberry is warm, sour and non-toxic, entering the two meridians of the liver and kidney, and has the functions of relieving thirst, expectorant, detoxification and beauty, which is helpful to the treatment of gout and other diseases. The content of vitamin E in raspberries also ranks first among all kinds of fruits. Natural superoxide dismutase and vitamin E are excellent scavengers of the human body, which can eliminate a large number of harmful metabolites produced by the human body, improve human immunity, fundamentally improve the internal environment of the human body, and achieve the purpose of beauty, beauty and longevity. Long-term consumption of raspberries can effectively protect the heart and prevent hypertension, vascular wall atherosclerosis, cerebrovascular sclerosis and other cardiovascular and cerebrovascular diseases.

Red raspberry seedlings

The reproduction methods of raspberry can be divided into sexual reproduction and asexual reproduction.

Limited propagation is the so-called seed propagation, but because the seedling has a large variation rate, it can not maintain the characteristics of the original variety, and the result is relatively late, so it is mainly used to cultivate new varieties. It can not be used to cultivate seedlings used in production.

Asexual reproduction includes cutting, tillering and tissue culture. Tissue culture is the safest and most effective method of propagation at present.

Domestication of tissue culture seedlings

Domestication is the process of pulling tissue culture seedlings outdoors for natural light treatment and then transplanting them to the seedling bed to grow into commercial seedlings. In addition, the seedling refining time had a certain effect on the survival rate of test-tube plantlets domesticated and transplanted. the 7-day survival rate was as high as 92.06%, and the rooting rate of tissue culture seedlings soaked in 2000 times algin solution for 5 minutes was up to 93.22%. The compound substrate with river sand: peat ratio of 1:2 is the most effective for raspberry rooting, and the rooting rate is as high as 92.7%.

Seedling bed treatment

To build a nursery bed, select the high dry terrain, good drainage and sufficient light to build the bed, and install pipes and sprinklers. The bottom of the seedbed is covered with 15 cm thick coarse cinder or vermiculite, the middle layer is covered with 10 cm coarse sand, and the upper layer is covered with 15 cm fine river sand. 2% potassium permanganate solution was sprayed for disinfection.

Planting

Plant 600 plants per mu with a row spacing of 1.8-2 meters and a plant spacing of 45-60.

Cultivation and management

Raspberry is a positive plant that likes light and can be planted with low pH of ph5-7. The soil is preferably sandy soil with good permeability and high content of organic matter. The planting land should be on the sloping land and flat land with open, flat and good drainage, which is convenient for fine management.

Creeping and semi-erect raspberry varieties should be set up in the second year of planting. Pruning is needed to control plant type at the end of each year or in spring.
