Abstract
The invention discloses plant transplanting nutrient paper and a preparation method thereof. The preparation method comprises the following steps: (1) by taking paper pulp fiber as the raw material, making the fiber paper by virtue of the links of pulping, drifting, netting, squeezing and drying; (2) soaking the fiber paper in a nutrient solution or coating the fiber paper with the nutrient solution; and (3) spraying a super absorbent resin on the fiber paper and drying. The plant transplanting nutrient paper can be directly bound around the root covering zone of the root of a plant or the lower portion of the main stem of the plant, or bound around the root covering zone of the plant to be transplanted after a little old bark is stripped off; as the moisture is transferred by the paper base material super absorbent resin, the transfer and transmission of the nutrient substances to the guide tube or the sieve tube of the main stem of the plant are realized; the defects of the existing suspended needle bag in the aspects of plant dermis tissue damage, poor nutrient solution feeding sustainability, poor biodegradability of the suspended needle bag made of a polymer and the like can be overcome; and the plant transplanting nutrient paper can be widely applied to the fields of the transplanting and protection of plants and the packaging and preservation of ornamental flowers.
Description
Technical field
The invention belongs to plant transplanting field, relate to a kind of plant transplanting nutrition paper, flooded by paper base material or be coated with plant nutrient substance layer, realize the sustainable weight feed transplanting nutrient for plants, improve the surviving rate of transplanting plant, be specially adapted to the transplanting of ornamental trees, flowers, or the Freshkeeping Packaging of fresh flower.
Background technology
Along with the development of Chinese society economy, people start more and more to pay attention to beautifying of town and country garden style and environment, a lot of gardens all need through nursery and migration process with plant, particularly fruit tree, greening or the strong trees of sight and flowers, such as, babassu, Ulmaceae, Ulmaceae, Fagaceae, canella, rose, carnation, tree peony, flower of Capa Jasmine etc.
At present; improve the methods such as the mainly big trees with bare root transplanting of plant transplanting method, large tree belt ball transplanting; by modes such as leaf pruning, naked protections of enclosing under overlapping slurry, root system water spray, trunk; realize the balance of moisture and nutritive ingredient; or weaken the destructiveness of migration process to plant Equilibrium, thus improve the surviving rate of ornamental plant.In addition, plant garter bag is widely used in the transplanting of plant, and mainly by certain density nutritive medium, by tubing, syringe needle etc. are delivered to the rhizome of plant, and to improve the surviving rate of plant transplanting, this design is to obtain national patent.Plant is a kind of novel plant organic liquid fertilizer with nutritive medium, containing a large amount of amino acid, comprehensively nutritive element and various bioactivators, is widely used in the drought resisting of plant, prevention and elimination of disease and pests, volume increase etc.Wang Sanwen etc. report oligose and the composite control to capsicum S.scabies and anthrax, citrus ulcer and paddy rice, maize sheath blight of plant nutrition liquid.Luo Peng etc. study discovery, and the composite nutritive medium of Gram suddenly contributes to gold leaf common bluebeard epicormic branch cuttage and takes root, and improves the synthesis of Populus hopeiensis bough water planting process Determination of Chlorophyll and slows down leaves water loss speed.The impact that the default combination that Qi Jianlong etc. compare root filling fertilising and garter transfusion increases income mango.Li Jiazhu etc. have studied the controlled release properties of super absorbent resin to moisture and nutritive element.Wei Kaiju etc. have studied the medicines such as Avrmectin, acetamiprid, pyridine worm quinoline by infusion method, affect the control of orange armored scale.Feng Jinchen etc. review the application of garter infusion techn in fruit tree drought resisting first aid.
Although existing plant transplanting nutrition garter bag can significantly improve the transplanting success of plant.But also there are some problems, such as nutritive medium is mainly by punching input plant roots and stems, cause the destruction of the dermal tissue of plant, the point-to-point input method of syringe needle is adopted easily to cause plant absorption efficiency not high, affect the use of viewing and admiring that the surviving rate of plant transplanting, the particularly age of tree are short, vitality is fragile to set; The lack of wisdom in the flow velocity controlling nutritive medium and concentration of plant garter bag, can only regulate the input flow velocity of nutritive medium by the simple and easy knob of manual shift, the concentration of nutritive medium is then fixed against the unified preparation of manufacturer; In addition, the high molecular polymers such as plant nutrient bag many employings poly terephthalic acid class plastics (PET), nylon, polyethylene (PE), bio-refractory, potential environmental hazard is large.Therefore, the present invention discloses a kind of plant transplanting nutrition paper, by forming high-hydroscopicity paper base material at fibre paper surface coated high-absorbent material layer, and to paper base material dipping or coating plant nutrient substance layer, by being coated on plant, being formed the mass transfer of nutritive medium by the moisture absorbed in air, achieving the sustainable weight feed transplanting nutrient for plants, achieve the high-survival rate of plant transplanting, simultaneously product has that environment-friendly type is good, the long-lasting high of nutritive substance.
Summary of the invention
