Description

Technical Field

[0001] The utility model relates to the technical field of artificial emasculation of tea trees, and specifically relates to a tool for artificial pollination and stamen removal of tea trees. Background Technique

[0002] Hybridization is currently the most widely used and most effective breeding method in tea tree breeding, and it is also one of the main ways to cultivate new tea tree varieties. Artificial pollination is a necessary process in cross-breeding. When carrying out artificial pollination, generally, the method of removing stamens first is adopted. At present, at home and abroad, mainly manual pinching to remove stamens or using a scissor-type cutter to remove stamens;

[0003] However, the stamens of tea trees grow outside the pistils and grow in a surrounding manner. When the existing emasculation tools are used for emasculation of tea trees, it is easy for the pollen of the stamens of the tea trees to fall on the pistils during the operation, causing the pistils to be polluted. At the same time, the pollen falling on the pistils will cause self-pollination, thereby reducing the genetic diversity of the population and having an adverse impact on the health and yield of tea trees.

[0004] In view of the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

By opening the first emasculation scissors rod and the second emasculation scissors rod, the two groups of stamen collection shells are separated from each other. By sleeving the pistil protective sleeve outside the pistil, the pistil is completely isolated from the stamens. Then, the stamens are cut by the emasculation blade. At this time, the stamen collection shells are closed, so that the cut stamens fall inside the stamen collection shells for collection. At the same time, the stamen collection shells are lifted upward, and the pistil protective sleeve prevents the pollen of the stamens from falling on the pistils during emasculation, resulting in self-pollination, thereby reducing the genetic diversity of the population and having an adverse impact on the health and yield of tea trees.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a tool for emasculating stamens in artificial pollination of tea trees.

[0021] Please refer to Figures 1 - 4 , a tool for emasculating stamens in artificial pollination of tea trees, including a tea tree emasculation mechanism 1, a first emasculation cutting rod 101 and a second emasculation cutting rod 102. The first emasculation cutting rod 101 is rotatably connected to the limit groove 203. A rotating rod 103 is rotatably installed between the first emasculation cutting rod 101 and the second emasculation cutting rod 102. A connecting rod 104 is fixedly installed at the bottom of the rotating rod 103. A pistil protective sleeve 105 is fixedly connected to the bottom of the connecting rod 104. An emasculation blade 107 is fixedly installed at the bottom ends of the first emasculation cutting rod 101 and the second emasculation cutting rod 102. The connecting rod 104 is located in the receiving groove between the first emasculation cutting rod 101 and the second emasculation cutting rod 102, and the pistil protective sleeve 105 is located at the middle position inside the stamen collection shell 106.

[0022] Specifically, by opening the first emasculation cutting rod 101 and the second emasculation cutting rod 102, the two stamen collection shells 106 are separated from each other. By sleeving the pistil protective sleeve 105 on the outside of the pistil, the pistil and the stamens are completely isolated. Then, the stamens are cut by the emasculation blade 107. At this time, the stamen collection shell 106 closes, so that the cut stamens fall inside the stamen collection shell 106 for collection. At the same time, the stamen collection shell 106 is lifted upward, and the pistil protective sleeve 105 prevents the pollen of the stamens from falling on the pistil during emasculation, resulting in self-pollination, thereby reducing the genetic diversity of the population and having an adverse impact on the health and yield of tea trees.

[0023] Furthermore, a emasculating blade 107 is fixedly installed at the bottom of the inner wall of the stamen collection shell 106. A round hole 108 is formed in the middle of the emasculating blade 107, and the pistil protective sleeve 105 is located inside the round hole 108;

[0024] Furthermore, finger rings 109 are fixedly installed at the tops of the first emasculating scissors rod 101 and the second emasculating scissors rod 102, and a sponge pad 110 is fixedly installed on the inner wall of the finger rings 109;

[0025] Specifically, by passing the finger through the finger ring 109 and then pinching the first emasculating scissors rod 101 and the second emasculating scissors rod 102 to close the stamen collection shell 106, the sponge pad 110 makes it more comfortable when the finger pinches the finger ring 109. The emasculating blade 107 is closed to perform the emasculating operation of cutting the stamens, and at the same time, the pistil protective sleeve 105 is located inside the round hole 108 to perform anti-pollution treatment on the pistil;

[0026] Furthermore, support blocks 111 are fixedly installed on the sides of the finger rings 109 close to each other, and the support blocks 111 are installed in a staggered manner. The ends of the support blocks 111 close to each other are made of rubber;

[0027] Specifically, when the staff pinches the finger rings 109 to make them close to each other and fit, the support blocks 111 close to each other fit with the finger rings 109. Since one end of the support block 111 is made of rubber, the finger rings 109 are buffered when approaching, so that the emasculating cutting is more stable;

[0028] Furthermore, a fixed frame 2 is movably installed on one side of the first emasculating scissors rod 101. A fixed rod 201 is fixedly installed at the rear end of the first emasculating scissors rod 101. A chute 202 is formed at the rear end of the fixed frame 2, and the fixed rod 201 is slidably installed inside the chute 202;

[0029] Furthermore, a limit groove 203 is formed at the bottom of the front end of the fixed frame 2. A limit rod 204 is fixedly installed at the front end of the second emasculating scissors rod 102, and the limit rod 204 is movably installed inside the limit groove 203;

[0030] Specifically, by sliding the fixed rod 201 inside the chute 202 to one side and then rotating the other end of the fixed frame 2 upward, when the first emasculating scissors rod 101 and the second emasculating scissors rod 102 are closed, at this time, the limit groove 203 is located at the top of the limit rod 204, and the fixed frame 2 is rotated downward to make the limit rod 204 slide into the limit groove 203, so that the first emasculating scissors rod 101 and the second emasculating scissors rod 102 are fixedly closed, avoiding the situation that the first emasculating scissors rod 101 and the second emasculating scissors rod 102 automatically open and cause damage during the carrying process.

[0031] Working principle: First, the staff unfolds the first emasculation cutting rod 101 and the second emasculation cutting rod 102, then puts the pistil protective sleeve 105 on the outside of the pistil of the tea tree. Next, by squeezing the finger rings 109 to approach each other, the stamen collection shells 106 approach and close to each other. At this time, the connecting rod 104 is received in the receiving groove on the side where the first emasculation cutting rod 101 and the second emasculation cutting rod 102 approach each other. The emasculation blade 107 cuts off the stamens outside the pistil protective sleeve 105, so that the stamens fall inside the stamen collection shell 106 for collection. Subsequently, the stamen collection shell 106 is lifted upward, and the pistil slides out from the bottom of the pistil protective sleeve 105, thus completing the emasculation of the tea tree while avoiding the risk of pistil contamination.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
