360 results about "Phloem" patented technology

Phloem (pronunciation: /ˈfloʊ.əm/) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to parts of the plant where needed. This transport process is called translocation. In trees, the phloem is the innermost layer of the bark, hence the name, derived from the Greek word φλοιός (phloios) meaning "bark". The term was introduced by Nägeli in 1858.

New technique for culturing apocarya by seeding and grafting in current year

The invention discloses a new technique for culturing apocarya by seeding and grafting in the current year. The technique comprises the following steps: culturing the apocarya in an improved outdoor sowing method for seedling in the current year; cutting the root when seedlings and seeds are transplanted from a seedbed to a nursery, and building a free stock nursery; selecting the robust apocarya seedlings in current year as the free stock which has leading thread more than or equal to 0.5cm from the seedlings sown in the current year; cutting the part of the free stock on the ground above 25cm in a week before grafting; choosing branches grown in the current year having full bud, short inter-node and rich development from a grain ear picking tree, and carrying out patch budding on the branch on the part of the free stock about 10-15cm on the ground in the solar terms having average daily temperature from 25 to 30 DEG C between August and September; and before wrapping up, tearing down a small phloem from the part under the free stock notch so as to ensure that the bleeding can flow out. By utilizing the technical scheme, the apocarya which is sown in the current year can grow into a tree having the thickness meeting the demand of grafting; and through grafting in the current year, the seedling period is shortened, the tree is dwarf, the juvenile phase is shortened, and the fructification is obtained earlier.

Method for producing paper pulp used in rice paper production by broussonetia papyrifera bark through steam-exploding degumming

The invention belongs to the field of phloem fiber resource utilization, in particular relates to a method for preparing high-quality paper pulp such as rice paper and the like by steam-explosion, degumming and cleaning of broussonetia papyrifera bark. The method comprises the steps as follows: firstly, the steam-explosion treatment of the broussonetia papyrifera bark is carried out; subsequently, rinsing and bleaching are carried out, thus obtaining the high-quality paper pulp. The no-pollution steam-explosion treatment degrades 80% of the pectin and hemicellulose and part of the lignin in the broussonetia papyrifera bark fiber, completely separates the external epidermis (black skin) of the broussonetia papyrifera from the internal layer phloem thereof simultaneously, and removes the black tissue of the external epidermis by the bleaching; furthermore, during the steam-explosion process, the bark fiber is torn to a loose structure, which leads the chemical drug to sufficiently permeate during the bleaching process and improves the whiteness of the paper pulp. The method reduces the industrial cost of the papermaking by broussonetia papyrifera bark, avoids the environmental pollution caused by chemical pulp preparation process and can improve the yield and quality of the paper pulp; and the paper pulp can be used for preparing high-quality paper such as rice paper, bank paper and the like. The invention provides a new method for clean high-value utilization of the broussonetia papyrifera bark resource and generates greater economic and social benefits.
