Embodiment 1

[0026] With reference to Fig. 1, a kind of water-retaining tree-planting material is compounded by two-layer plant fiber substrate 1 and the water-retaining layer 2 between the two-layer substrate. The plant fiber substrate 1 is made from rice straw according to the method of pulping and papermaking. The water-retaining layer 2 is made of a water-retaining agent.

[0027] The preparation method of the water-retaining tree-planting material comprises the following steps: smearing an adhesive on one side of the substrate, spreading the water-retaining agent flatly, and then pressurizing and compounding the two layers of substrates to obtain the water-retaining tree-planting material.

Embodiment 2

[0029] With reference to Fig. 1, a kind of water-retaining tree-planting material is compounded by two-layer plant fiber substrate 1 and the water-retaining layer 2 between the two-layer substrate. The plant fiber substrate 1 is prepared by the following method: uniformly mix corn stalks and a binder, put them into a molding machine, and punch them under high temperature and high pressure; the binder is selected from cornstarch. The water-retaining layer 2 is prepared by mixing a water-retaining agent and a plant nutrient.

[0030] The preparation method of the water-retaining tree-planting material comprises the steps of: applying an adhesive on one side of the base material, spreading the mixture of the water-retaining agent and the plant nutrient, and then pressing and compounding the two layers of base materials to obtain the water-retaining tree-planting material.

Abstract

The invention relates to a water-retaining tree-planting material and a preparation method thereof. The water-retaining tree-planting material is composed of two layers of plant fiber substrates and a water-retaining layer between the two layers of substrates. The preparation method of the water-retaining tree-planting material comprises the following steps: smearing an adhesive on one side of the substrate, spreading the water-retaining agent flatly, and then pressurizing and compounding the two layers of substrates to obtain the water-retaining tree-planting material. The water-retaining tree-planting material of the invention is green and environment-friendly, simple to manufacture, convenient to use, wide in application range, superior in market prospect, good in use effect and stable in performance.

Description

(1) Technical field [0001] The invention relates to a water-retaining tree-planting material and a preparation method thereof. (2) Background technology [0002] Improving the survival rate of tree planting in arid areas, especially in desert areas, is an important issue before arborists. In recent years, some tree-planting bag products have appeared, such as the new water-saving and water-retaining container tree planting technology jointly researched and developed by Jilin Oasis Ecological Engineering Co., Ltd. and the Science and Technology Development Center of the State Forestry Administration. , coated with bio-extracted organic polymer film to make a tree planting container. When planting trees, the saplings are placed in the container, then filled with soil and watered. This kind of container has the characteristics of being air-permeable, impervious to water, non-toxic, harmless and degradable, and its organic polymer film can be absorbed by plant roots. The prob...
