Plant transplanting nutrient paper and preparation method thereof

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

[0001] The invention belongs to the field of plant transplantation, and relates to a nutrient paper for plant transplantation, which realizes sustainable quantitative supply of transplanted plant nutrients by impregnating or coating a plant nutrient layer with a paper base material, and improves the survival rate of transplanted plants, and is especially suitable for viewing Transplantation of sexual trees and flowers, or fresh-keeping packaging of flowers. Background technique

[0002] With the continuous development of my country's social economy, people began to pay more and more attention to urban and rural landscaping and the beautification of the environment. Many garden plants need to go through the process of seedling breeding and transplanting, especially fruit trees, greening or ornamental trees and flowers, such as , Palmaceae plants, Ulmaceae plants, Ulmaceae plants, Fagaceae plants, Lauraceae plants, roses, carnations, peonies, gardenias, etc. ...
