Description

Technical Field

[0001] The utility model relates to the technical field of corn cultivation tools, in particular to a corn embryo peeling spoon. Background Art

[0002] Corn is the food crop with the largest planting area and the highest yield in my country. It is also an important feed crop and cash crop in the world. Before the 1980s, conventional breeding through sexual hybridization to achieve gene recombination was the main means of corn variety selection. With the rapid development of molecular breeding technology, transgenic technology has been gradually widely used in the genetic improvement of corn and has shown great market value. In 2023, the global planting area of ​​transgenic crops will be 206.3 million hectares (3.09 billion mu), which is 118 times that of 1996 (1.7 million hectares). At present, 34.0% of the corn in the world's major crop planting area is transgenic. In the Agrobacterium-mediated corn genetic transformation technology, the young embryos of about 1.8 mm in size must be peeled out from the corn kernels about 12 days after pollination in a sterile environment in a clean bench, and infected with Agrobacterium, so as to transform the target gene into the corn genome. Because the young embryos of corn are too small and have low vitality, they cannot be damaged during the peeling process. If they are damaged, they will be difficult to survive after infection with Agrobacterium, and sterile operation is required, which is difficult. In the prior art, experimenters usually use a scalpel to peel off the immature embryos of corn. Since the junction between the corn kernel shell epidermis and the endosperm is arc-shaped, the scalpel head is too straight, making it difficult to fit the epidermis and take out the endosperm, resulting in low embryo peeling efficiency. In addition, the scalpel head is relatively thin and sharp, which can easily cut the immature embryos, resulting in a large number of immature embryos lost, which reduces the conversion efficiency of corn to a certain extent. Summary of the invention

[0003] In view of the deficiencies in the prior art, the utility model provides a corn embryo peeling spoon, which solves the problem in the prior art that test personnel usually use a scalpel to peel off the immature corn embryo. Since the junction between the corn kernel shell skin and the endosperm is arc-shaped, the scalpel head is too straight, and it is difficult to fit the epidermis to take out the endosperm and peel off the immature embryo, resulting in low embryo peeling efficiency; and the scalpel head is relatively pointed and sharp, which can easily cut the immature embryo, resulting in a large amount of immature embryo loss, which reduces the conversion efficiency of corn to a certain extent.

[0004] To achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a corn germ peeling spoon, including a spoon head, a spoon handle rod is provided at one end of the spoon head, a shuttle-shaped groove is provided on the front of the spoon head, a back protrusion is provided on the back of the spoon head, and an arc end is provided at the end of the spoon head away from the spoon handle rod.

[0005] Preferably, the end of the spoon handle rod away from the spoon head is cooperated with a spoon handle sleeve, the outer wall of the spoon handle rod is equidistantly provided with limiting convex patterns, the inner wall of the spoon handle sleeve is equidistantly provided with limiting grooves, and the limiting convex patterns are cooperated with the limiting grooves.

[0006] Preferably, a fixed end is provided at one end of the spoon handle sleeve away from the spoon head, a fixing hole is provided inside the fixed end, and a metal ring is embedded inside the fixed end and located outside the fixing hole.

[0007] Preferably, the outer wall of the spoon handle sleeve is provided with knurled anti-slip patterns.

[0008] Preferably, a transition bevel is provided on one end of the outer wall of the spoon handle sleeve close to the spoon head.

[0009] The utility model provides a corn embryo peeling spoon. The utility model has the following beneficial effects: the corn embryo peeling spoon has a spoon head, a spoon handle, a fusiform groove, a back protrusion and an arc end, and the spoon head portion of the embryo peeling spoon is designed with a fusiform groove according to the fitting shape of the corn kernel endosperm and seed coat, and the end of the spoon head adopts a relatively blunt arc design, which can quickly take out the endosperm, thereby separating the young embryo and reducing the probability of damage to the young embryo of corn. The manufacturing materials are relatively common, the price cost is low, and it is easy to produce, which helps to improve the success rate of corn young embryo cultivation.

[0010] Through the cooperation among the spoon handle rod, the spoon handle cover, the limiting convex pattern and the limiting groove, and by putting the spoon handle cover on the rear end of the spoon handle rod, it is convenient for the staff to hold the embryo peeling spoon, which can improve the stability of holding the embryo peeling spoon and avoid the embryo peeling spoon from slipping or rotating during operation, thereby improving the stability and safety of young embryo separation. At the same time, the spoon handle cover is made of high-temperature resistant plastic material or silicone material and has a certain heat insulation effect. After the embryo peeling spoon is sterilized at high temperature, the spoon handle cover can play a heat insulation role, thereby preventing burns to the hands of the staff, which makes it easier for the staff to hold and use the embryo peeling spoon.
