Description

Technical Field

[0001] The invention relates to the technical field of cutting propagation, and in particular to a winter heat preservation device for a cutting pool and an application method thereof. Background Art

[0002] In the production process, cutting propagation in asexual reproduction is one of the important methods to maintain the characteristics of excellent varieties. However, some plants face many challenges when cutting in winter, such as cutting quality, temperature, humidity, exogenous hormones, etc.

[0003] In winter, cuttings are not easy to rot because the outside temperature is relatively low. In addition, the period after winter and before spring is the phenological node for plant germination, which can increase the survival rate of cuttings of some woody plants that are not easy to propagate by cuttings.

[0004] However, due to the low temperature in winter, it is not conducive to the healing of cuttings, and the low substrate temperature will affect the rooting speed of cuttings. In the prior art, geothermal lines have not been applied to the research and application of cutting rooting rate.

[0005] Therefore, the present invention provides a winter heat preservation device for a cutting pool and an application method thereof, so as to solve the problem in the prior art that when asexual reproduction is performed, the temperature in winter is low, which is not conducive to the healing of the cuttings, thereby affecting the rooting speed of the cuttings. Summary of the invention

[0006] The present invention aims to provide a winter heat preservation device for a cutting pool and an application method thereof, so as to solve the problem in the prior art that when asexual reproduction is carried out, the temperature in winter is low, which is not conducive to the healing of the cuttings, thereby affecting the rooting speed of the cuttings.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] The basic technical solution provided by the present invention is: a winter insulation device for a cutting pool and an application method thereof, comprising a cutting pool, wherein an extruded board is arranged at the bottom end inside the cutting pool, a reflective film is arranged on the upper surface of the extruded board, geothermal wires are evenly laid above the reflective film, the extruded board is detachably connected with a buckle for fixing the geothermal wire, and a matrix layer is arranged above the reflective film.

[0009] Furthermore, the buckle is detachably connected to the extruded plate via screws.

[0010] Furthermore, the interior length of the cutting pool is 300 cm and the width is 120 cm.

[0011] Furthermore, the matrix layer is composed of powdery fine sand and has a thickness of 20-25 cm.

[0012] Furthermore, the cutting pool is provided with a bracket.

[0013] The above-mentioned application method of a cutting pool winter insulation device comprises the following steps:

[0014] S1. The substrate layer is heated by geothermal lines to a temperature of 20-25°C;

[0015] S2, pre-treat the cuttings to improve their rooting rate;

[0016] S3, insert the cutting branches obtained by S2 into the substrate layer with a row spacing of 10 cm and a plant spacing of 4 cm, and compact the substrate layer;

[0017] S4. After cutting, the shading rate is controlled at 50%, and the cutting branches are sprayed with an automatic spray device, 3 times a day. The time of each spraying is set to 5 minutes in the first week, and the time of each spraying is set to 2 minutes after one week, and the interval time between each spraying is the same.

[0018] Furthermore, in step S1, the output power of the electric heating wire is set to 18.5 W / m 2 .

[0019] Furthermore, in step S2, the specific method for pre-treating the cuttings is:

[0020] First, select semi-lignified branches and cut off the top 15-20 cm; immediately soak them in clean water and remove the bottom needles; then bundle 30 branches into a bundle, soak them in 0.1% potassium permanganate solution for 2 hours to elute, and use branch shears to knock the cut of the spike to increase the callus area; before cutting, use 0.1g ABT1 rooting powder dissolved in a small amount of alcohol, add 10kg water, and soak for 1 hour to obtain branches suitable for cutting.

[0021] The beneficial effects of the technical solution are:

[0022] When the heating wire is powered on, electrical energy is converted into thermal energy, the extruded board plays a role of insulation, and the reflective film ensures that the heat energy is radiated upward to ensure that the substrate layer is evenly heated, thereby providing a stable heat source for the substrate layer, keeping the substrate layer at a suitable temperature and maintaining the smooth growth of the cuttings; the humidity of the cuttings is adjusted by the automatic spray system, which improves the health and growth rate of the vegetation and prevents the problem of the substrate layer being too dry due to bottom heating.
