Detailed Description

The following combines the utility model discloses an attached drawing is right the technical scheme and the technological effect of the embodiment of the utility model are further elaborated.

Referring to fig. 1, in an embodiment, a rooting promoting seedbed 10 for grape seedling cultivation is used for placing grape seedlings for rooting and seedling cultivation, and includes a bed base layer 100, a heat insulating layer 200, a moisture preserving layer 300, a heat insulating layer 400, a heating layer 500 and a rooting layer 600, wherein the heat insulating layer 200 is laid on the bed base layer 100, the moisture preserving layer 300 is covered on the heat insulating layer 200, the heat insulating layer 400 is covered on the moisture preserving layer 300, and the heating layer 500 is buried between the heat insulating layer 400 and the rooting layer 600. The rooting promoting seedbed 10 for grape seedling raising further comprises a root zone covering layer 700, wherein the root zone covering layer 700 is stacked on the rooting layer 600 to cover the root zone of the grape seedling placed on the rooting layer 600.

When grape seedling is grown, grape seedlings are bundled and densely placed on the rooting layer, and sand or seedling substrate is scattered along gaps among the seedlings from top to bottom to form the root zone covering layer 700 in a stacked manner.

The seedbed establishing process comprises the steps that the seedbed base layer 100 serves as a support, the seedbed base layer 100 can be a soil pit formed by plowing soil ridges or digging soil pits or a basin-type containing container, a straw curtain or sawdust with the thickness of 1 cm-3 cm is paved on the seedbed base layer 100, and a high-cost heat insulation material can be arranged to form the heat insulation layer 200, the heat insulation layer 200 mainly serves to reduce heat exchange between the seedbed and the environment, meanwhile, the seedbed base layer 100 and the heat insulation layer 200 have certain permeability, and normal ventilation of the seedbed is guaranteed. After the heat insulation layer 200 is laid, a layer of plastic film or plastic cloth is laid on the heat insulation layer to form the moisture preservation layer 300, and when the moisture preservation layer is used, the moisture preservation layer can prevent water on the upper portion of the seedbed from losing, and can prevent toxic and harmful substances from the bed base layer 100 and the heat insulation layer 200 from returning to the upper portion of the seedbed to substantially affect the rooting of grape seedlings.

The moisture retention layer 300 is covered with 10 cm-30 cm of sandy soil to form the heat preservation layer 400, the relative compactness of the sandy soil of the heat preservation layer is 0.33-0.67, and the sandy soil has a good heat storage effect, so that the relative balance of the temperature of the seedbed is favorably maintained, and the large-amplitude change of the temperature is reduced. Meanwhile, the heat-insulating layer 400 formed by the selected sandy soil with medium compactness has good water-containing performance and air permeability, and can continuously provide moisture support for the upper surface of the seedbed so as to ensure the humidity of the seedbed and improve the air permeability of the seedbed.

And installing an electric heating coil or a hydrothermal coil on the heat preservation layer 400 to form the heating layer 500 so as to provide a heat source for the seedbed, covering the heating layer 500 with sandy soil with the relative compactness of 0.20-0.45 and being 3-5 cm higher than the heating layer to form the rooting layer 600 for placing grape seedlings and inducing the grape seedlings to take roots. When urging root, make zone of heating 500 opens, is in the heating state, the heat that zone of heating 500 released is partly by the rooting layer 600 absorbs, in order to keep the temperature of the sandy soil of rooting layer 600 is higher than air temperature 5 ℃ -7 ℃, partly quilt heat preservation 400 absorbs to the heat accumulation utilizes this heat accumulation to adjust the temperature balance of seedbed on the one hand, and on the other hand accelerates moisture evaporation in the heat preservation 400, for rooting layer 600 provides the soil moisture who satisfies the growth demand. Due to the existence of the heat insulation layer 400, the heating layer 500 is not required to be always in an open state, so that energy is saved, and the seedling raising cost is reduced.

Referring to fig. 2, preferably, the rooting promoting seedbed 10 for grape seedling raising further includes a humidifying layer 800, the humidifying layer 800 is embedded in the heat insulation layer 400, and the humidifying layer 800 is a water coil pipe with water seepage holes. When the water storage capacity of the heat preservation layer 400 cannot meet the humidity requirement of grape nursery stock rooting, warm water is introduced into the water coil pipe of the humidification layer 800, and the warm water permeates into the heat preservation layer 400 through the water seepage holes of the water coil pipe to provide sufficient water for the heat preservation layer 400.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
