Embodiment 1

[0024] The seedlings grown from the natural fruit drop of the provenance clam wood in the natural distribution area are harvested and planted in a black container with a size of 20×20cm. The cup is filled with 90 parts by weight of yellow heart soil, 3 parts by weight of coconut chaff soaked dry material and chicken manure pile. 7 parts by weight of retting material are artificially mixed in the matrix of the mother plant, and then drenched with root water as the ear picking nursery. Cover the ear-picking garden with a layer of 70% shading net for shade. After one month, when the seedlings have recovered and stabilized, the shading net can be uncovered, and at the same time topping can be used to promote germination. , Spray fungicides every 14 days to prevent and control diseases. Use a black container cup with a size of 12×14cm to fill the cuttings with 98% yellow core soil and 1.6% fine sand matrix, and sterilize with 2% potassium permanganate for later use; the buds will h...

Embodiment 2

[0026] The seedlings grown from the natural fruit drop of the provenance clam wood in the natural distribution area are picked back, planted in 90 parts by weight of yellow heart soil, 2.5 parts by weight of coconut chaff soaked and retting dry material and 7.5 parts by weight of chicken manure heap retting material and artificially mixed as Mother plant substrate, in a black container cup with a size of 20×20cm, as a picking nursery, then drenched with root water, covered with a layer of 70% shading net for shade, and opened after 1 month when the seedlings recovered and stabilized Shade nets, topping to promote germination at the same time, keep an appropriate amount of water during the period, neither too dry nor too wet, and spray fungicides every 10 days to prevent and control diseases. Use a black container cup with a size of 12×14cm to pack the cuttings of the yellow core soil substrate with the topsoil removed, and sterilize it with 2% potassium permanganate for later u...

Embodiment 3

[0028]The seedlings grown from the natural fruit drop of the provenance clam wood in the natural distribution area are picked back, and planted in a mixer with 90 parts by weight of yellow heart soil, 3.5 parts by weight of coconut chaff soaked and retting dry material, and 6.5 parts by weight of chicken manure heap retting material in a mixer. Finally, use it as the substrate of the mother plant, in a black container cup with a size of 20 × 20 cm, as the ear picking garden, then drench the root water, cover with a layer of 70% shading net for shade, and wait for the seedlings to recover and stabilize after 1 month. Uncover the shading net, topping to promote germination at the same time, keep an appropriate amount of water during the period, neither too dry nor too wet, and spray fungicides every 12 days to prevent and control diseases. Use a black container cup with a size of 12×14cm to pack the matrix cuttings with 98% of the weight of yellow core soil and 2% of the weight o...

Abstract

The invention discloses a method for cuttage seedling of buerretiodendron hsienmu at all seasons. The method comprises the culturing processes of provenance collecting, slip garden planting, cutting slip collecting, cuttage and seedling cutting. The method is characterized by comprises the steps of collecting plantlets growing through the natural fruit drop of the provenance of the buerretiodendron hsienmu in a nature distribution area, transplanting the plantlets into a container with arranged matrixes to be taken as a slip picking garden, selecting proper cutting slips, processing the cutting slips and then conducting the cuttage, adopting different cultivation management measures according to different seasons after the cuttage to obtain good and healthy planting plantlets of buerretiodendron hsienmu. According to the method, a technology for cuttage seedling of buerretiodendron hsienmu at all seasons is provided and has the characteristics that the planting of the buerretiodendron hsienmu is not limited by the seasons and regions, the rooting percentage of the cutting slips is high, the breeding speed is quick, the method is simple, the operation is easy, the survival rate is high, the plantlets are good and healthy, and the like, the rapid seedling culturing of the buerretiodendron hsienmu which belongs to the national secondary-class protected plant is realized, the difficulty of difficult generative propagation of the buerretiodendron hsienmu is solved, the favorable condition is created for the rapid breeding of rare tree, namely the buerretiodendron hsienmu, and the economical benefits and the social benefits are good.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and relates to a method for growing seedlings by four-season cuttage of clams. Background technique [0002] Clam wood is a precious timber tree species in the local area, and it is a national second-class protected plant. It has very few resources in my country and is currently only distributed in the limestone areas of southwestern Guangxi and southern Yunnan. Clam wood is very hard, wear-resistant, non-destructive by insects, and does not rot when wet. It has been determined that the hardness of clam wood is 2136N / mm 2 , impenetrable by knives, impenetrable by nails, known as "iron wood" and "green steel", has extremely excellent properties, and is a precious material for ships, vehicles, machinery, axles, high-end furniture, special buildings, etc. However, clam wood grows in the depths of the mountains, scattered scattered, tall trees, up to 50m, diameter at breast hei...
