Description

Technical Field

[0001] The utility model belongs to the technical field of cochineal breeding, and particularly relates to a novel cochineal breeding device. Background Art

[0002] The pear cactus is the object of cochineal parasitism in nature. Cochineal is usually covered with white wax powder and filamentous threads and appears in clusters. After hatching, the larvae seek a place to fix. The insect has a touch-taxis habit and likes to fix on the base of the thorn or uneven places. At the same time, the insect has negative phototaxis and is more sensitive to light. They usually choose to fix on the shady side of the stem and will not move once fixed. There are currently two common methods for breeding cochineal. One is to directly place the cochineal on the cactus for breeding. The other is to pick the appropriate cactus stem pieces and hang them up. Before hanging, put the cochineal in a triangular paper bag in the middle of the leaves on one side of the cactus.

[0003] However, the above-mentioned prior art methods have the following defects: 1. They are easily affected by environmental changes, such as temperature, humidity, light exposure time and other organisms on the cactus. 2. Only a certain number of cochineal insects can be cultivated on a cactus leaf, which makes it difficult to form large-scale cultivation. 3. The cactus has an irregular shape and low space utilization.

[0004] Therefore, how to further improve the controllability of cochineal farming and form large-scale farming is a problem that needs to be solved. Summary of the invention

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a novel cochineal breeding device. By using the device to breed cochineal, the activity of cactus stem pieces can be maintained to the greatest extent and the influence of the growth period of cactus stem pieces on cochineal breeding can be effectively reduced. At the same time, the breeding process can be made more modular and the space utilization rate can be greatly increased.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] A novel cochineal breeding device comprises a culture dish and a culture dish cover, which are two separate independent parts; a block of cactus stem pieces are laid flat in the culture dish, and a biological coagulation fixing material layer is formed by adding liquid biological coagulation fixing material into the culture dish and solidifying it, wherein the upper surface of the biological coagulation fixing material layer is lower than the upper surface of the cactus stem piece; a triangular bag is placed at the central position of the upper surface of the cactus stem piece, and a plurality of cochineal species are contained in the triangular bag; the culture dish cover is placed on the culture dish and is suitable for covering the open space on the upper part of the culture dish, and a plurality of air holes are arranged on the culture dish cover.

[0008] Furthermore, the culture dish is circular, square or rectangular, and the shape of the culture dish cover matches it.

[0009] Further, the size of the cactus stem piece is smaller than the inner diameter of the culture dish.

[0010] Further, the biological condensation fixing material includes agar and biological gel.

[0011] Further, the triangular bag is made of paper.

[0012] The beneficial effects of the present utility model compared with the prior art are as follows:

[0013] 1. By using the novel cochineal breeding device of the present utility model, indoor breeding of cochineal can be realized, thus avoiding rain washing, and the temperature, humidity and light can be controlled, and inoculation and harvesting are convenient;

[0014] 2. After washing, drying and cutting the cactus stem pieces, the breeding process can be made more modular, and the space utilization rate is greatly increased. On average, 720 - 1000 cochineal breeding petri dishes can be placed in a space of one cubic meter. While fixing the cactus, the biological condensation fixing material layer has a certain water retention effect, which can maintain the activity of the cactus stem pieces to the greatest extent and weaken the restraint of the growth period of the cactus stem pieces on cochineal breeding as much as possible; by using the novel cochineal breeding device of the present utility model, it is possible to produce cactus in one place and breed cochineal in another place, creating conditions for large-scale production; in addition, the cut cultivation of cactus stem pieces has a higher utilization rate of cactus than the indoor breeding technology of threading cactus stem pieces with iron wire in the prior art, and the cost is relatively low.

[0015] 3. The novel cochineal breeding device of the present utility model has a clever structural design and low manufacturing cost; the use method is simple, easy for workers to master, does not require professional training, and is suitable for large-scale promotion.

[0020] Embodiment 1

[0021] As Figure 1 、 Figure 2As shown, this embodiment provides a novel cochineal breeding device, including a culture dish 1 and a culture dish cover 5, which are two separate independent parts that can be separated. The culture dish is square (specification 15cm*15cm*2cm), and the culture dish cover matches it. The cactus stem piece 2 is cut into blocks suitable for the size of the culture dish, and the block cactus stem piece 2 is placed in the culture dish 1. The size of the cactus stem piece (about 14.5cm*14.5cm) is smaller than the inner diameter of the culture dish, so that it can be laid flat in the culture dish. A biological coagulation fixing material layer 3 is formed by adding liquid biological coagulation fixing material into the culture dish and cooling and solidifying. The upper surface of the biological coagulation fixing material layer 3 is lower than the upper surface of the cactus stem piece 2. Among them, the thickness of the cactus stem piece 2 is about 10-18mm, and the thickness of the biological coagulation fixing material layer 3 after cooling and solidification is about 8-16mm. After the biological coagulation fixing material layer 3 is solidified, a triangular bag 4 is placed at the center of the upper surface of the cactus stem piece 2, and a plurality of cochineal species 401 are contained in the triangular bag 4; the culture dish cover 5 is placed on the culture dish and is suitable for covering the open space at the upper part of the culture dish, and a plurality of air holes 501 are arranged on the culture dish cover.

[0022] The biological coagulation fixing material includes agar and biological gel. When agar is used, it is 15g / L and sterilized at 121°C for 20min; when biological gel is used, it is 3g / L and sterilized at 121°C for 20min. Since the cactus stem piece 2 is immersed in the biological coagulation fixing material except for the upper surface, the biological coagulation fixing material layer 3 formed by cooling and solidification has a water retention effect, which can maintain the activity of the cactus stem piece, thereby reducing the constraints of the cactus stem piece on the cultivation of cochineal as much as possible during the growth period.
