Embodiment 1

[0017] Weigh 10g of sand, 85g of mushroom slag, and 5g of peach gum, pulverize, stir, mix, and sieve the above raw materials, and press them into a circular cake-shaped compressed matrix block with a height of 2-3cm and a diameter of 3cm. The center of the press is used to place the pit of the tree species, the diameter of the pit is 8mm, and the depth is 3mm.

[0018] The compressed matrix block made according to the above formula quantity has a volume expansion ratio of 4.5 times after absorbing water.

Embodiment 2

[0020] Weigh 19.5g of sand, 80g of decomposed pine bark, and 0.5g of peach gum, pulverize, stir, mix, and sieve the above raw materials, and press them into a circular cake-shaped compressed matrix block with a height of 2-3cm and a diameter of 3cm. A pit for placing tree species is pressed in the center of the compressed matrix block, with a diameter of 8 mm and a depth of 3 mm.

[0021] The compressed matrix block made according to the above formula quantity has a volume expansion ratio of 3 times after absorbing water.

Embodiment 3

[0023] Weigh 15g of sand, 40g of decomposed pine bark, 44.9g of decomposed straw, and 0.1g of peach gum. After crushing, stirring, mixing and sieving the above raw materials, press them into a round cake with a height of 2-3cm and a diameter of 3cm. Shaped compressed matrix block, in the center of the compressed matrix block, a pit for placing tree species is pressed, the diameter of the pit is 8mm, and the depth is 3mm.

[0024] The compressed matrix block made according to the above formula quantity has a volume expansion ratio of 3.5 times after absorbing water.

Abstract

The invention discloses a compression-type forest tree seed cultivating substrate which is made into a compression block through blending the following raw materials in percentage by weight: 10-20% of sandy soil, 75-85% of decomposed forestry and agricultural residues and 0.1-5% of peach gum. The compression-type forest tree seed cultivating substrate is low in cost and capable of achieving the effects of sufficiently utilizing a great number of cheap forestry and agricultural residues, creating economic benefits and bringing environment benefits. A product produced by using the compression-type forest tree seed cultivating substrate can be supplied to nursery stock enterprises and forestation enterprises in batch for large-scale forest tree propagation, can also be sold on the market and cultivated in a household by an individual person to enjoy the pleasure; and meanwhile, the cultivated nursery stock can also be transplanted outdoors, so that the environment is indirectly protected. The compression-type forest tree seed cultivating substrate can be used for increasing the germination rate of tree seeds and plays a role in strengthening seedlings.

Description

technical field [0001] The invention relates to a forest tree cultivation substrate, in particular to a compressed forest tree species cultivation substrate. Background technique [0002] The cultivation of forestry seedlings can generally be completed in two ways. One is to use cuttings, tissue culture and other methods of asexual reproduction. Asexual reproduction can achieve the purpose of maintaining the excellent traits of the improved species and rapid reproduction, but it also has its fundamental shortcomings, namely Asexually propagated forest trees have poor performance in terms of diversity, adaptability to changing environments, and stress resistance; the second is to adopt the method of sexual reproduction, that is, to use seeds for reproduction, and the seedlings obtained from seed breeding have stronger adaptability , and can maintain the diversity of species genetic resources, so that large-scale pests and diseases or extinction of species caused by accidental...
