Description

Technical Field

[0001] The invention relates to sericulture technology, in particular to an automatic clustering method for silkworms without picking. Background Art

[0002] At present, the upper cluster cocooning in silkworm breeding mostly adopts square cluster, and the silkworms enter the grid of the upper cluster on the upper cluster frame to cocoon, which saves manpower and is highly efficient. However, mature silkworms have the habit of climbing upwards, so when silkworms go up to the cluster, they usually climb to the upper part of the square cluster before entering the grid. Therefore, the mature silkworms that go up to the cluster first will enter the grid at the upper part of the square cluster first, and the mature silkworms that go up to the cluster later will have no grid to enter when they climb to the upper part of the square cluster. Although the space of the grid can only accommodate one mature silkworm, some mature silkworms will still enter the grid with existing silkworms, resulting in two silkworms in one grid, or some mature silkworms will climb to the upper cluster frame on the upper side of the square cluster to form wandering silkworms, which is easy to form double palace cocoons and yellow spot cocoons when cocooning, affecting the quality of cocooning. Therefore, in order to solve the above problems, when silkworms are clustered, silkworm farmers need to turn the cluster over after a certain proportion of silkworms have entered the holes in the upper part of the grid cluster, so that the grid cluster is swapped up and down to ensure that there are still empty holes for the silkworms to enter when they climb to the upper part of the grid cluster, and try to avoid two silkworms in one hole. At the same time, the wandering silkworms on the cluster rack should be picked up and re-clustered. The operation is cumbersome, and the time for turning the cluster over and picking up the wandering silkworms is concentrated. Moreover, each silkworm rack has about 25,000 silkworms and requires more than 200 grid clusters. The large number of grid clusters leads to high labor intensity and high labor, which seriously restricts the large-scale development of mulberry silkworm production. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an automatic clustering method for silkworms without turning the clusters, which is simple to operate, avoids wandering silkworms, has low labor intensity and requires less labor, and does not require picking wandering silkworms.

[0004] In order to solve the above technical problems, the technical solution of the present invention is: an automatic clustering method for silkworms without picking, comprising the following steps:

[0005] (1) Add molting hormone to the silkworms. When 3-7% of the silkworms are mature, pick up the early-maturing silkworms and then feed them on the silkworm bed at a rate of 150-300 g / m 2 Sprinkle fresh lime powder, then lay silkworm nets to feed mulberry, and spray molting hormone on mulberry leaves;

[0006] (2) Collect the silkworm heads, add molting hormone, and apply 20-25 minutes per silkworm. 2 The silkworm heads are concentrated according to the standard, and the silkworm seats are arranged so that the silkworms are evenly distributed on the seats;

[0007] (3) Place the cluster rack and fix the upper cluster rack above the silkworm seat behind the silkworm head. Then hang the square clusters evenly on the upper cluster rack, with the lower edge of the square clusters touching the silkworm body. The square clusters are inclined at an angle of 70-80 degrees to the ground, and the distance between the square clusters is 12-16 cm.

[0008] (4) The mature silkworms on the silkworm seat automatically crawl into the holes on the square cluster to go up to the cluster;

[0009] (5) Driving the wandering silkworms to the clusters at one time, as the silkworms gradually mature, the mature silkworms also gradually climb up the clusters and onto the grid clusters. The mature silkworms that first climb onto the grid clusters enter the cells on the upper part of the grid clusters. If there are wandering silkworms crawling on the upper cluster frame, spray the wandering silkworms on the upper cluster frame with a clustering agent solution to drive the wandering silkworms on the upper cluster frame down to the grid clusters for clustering. At this time, the upper part of the grid clusters can also be sprayed with a clustering agent solution. Preferably, the amount of the clustering agent solution sprayed on the upper part of the grid clusters is less than the amount of the clustering agent solution sprayed on the upper cluster frame. Because the inclination angle of the grid clusters is relatively large, the clustering agent solution sprayed on the upper part of the grid clusters is basically attached to the cell mouths while the cells in the cells are not covered. The pores are free of the smell of the clustering agent, or the smell is small, which has little effect on the silkworms that have entered the pores. At this time, if there are two silkworms in the pores, the one on the outside will be affected by the clustering agent and crawl out of the pores and move to the lower part of the square cluster and enter the pores at the lower part of the square cluster. At the same time, because the amount of clustering agent solution sprayed on the upper cluster rack is large, the wandering silkworms will quickly move to the lower grid cluster to avoid the smell of the clustering agent, and the clustering agent solution at the openings of each pore on the upper part of the square cluster will have a certain effect on the wandering silkworms. In this way, when there are silkworms in the pores on the upper part of the square cluster, the wandering silkworms will cross the pores and enter the vacant pores to avoid the smell.

[0010] (6) Continue to drive away the wandering silkworms, and the mature silkworms that subsequently climb onto the grid cluster enter the cells at the bottom of the grid cluster. After a period of time, if there are wandering silkworms crawling on the upper cluster frame, spray the wandering silkworms on the upper cluster frame with the climbing agent solution again to drive the wandering silkworms down to the upper grid cluster, so that the silkworms can climb onto the cluster. Because the climbing agent solution sprayed on the upper grid cluster has a certain smell, most of the mature silkworms that subsequently climb onto the grid cluster are affected by the smell and no longer climb up, but choose to enter the lower grid cluster. The automatic clustering of the square cluster is basically completed in the grid; but some mature silkworms will still continue to climb up or even climb onto the cluster frame to form wandering silkworms. At this time, the wandering silkworms on the cluster frame are sprayed with the clustering agent solution again to drive the wandering silkworms down to the grid cluster and enter the grid. For the very few grids with two mature silkworms on the grid cluster, the late mature silkworms can be picked out and placed in empty grids or re-clustered; during the entire process of mature silkworms clustering, there is no need to turn over the square cluster to achieve clustering, which has low labor intensity and saves labor.

[0011] Among them, ecdysone and dendrite are existing products and can be purchased commercially.

[0012] As a preferred technical solution, the number of holes on the square grid cluster is 162, and each silkworm needs 200-250 square grid clusters. There are also a small number of square grid clusters with 325 holes, which can be adjusted according to the number of silkworms per sheet;

[0013] The time interval for spraying the clustering agent solution in step (6) is 10-14 hours. After this time period, there are basically no vacant cells on most of the square clusters, and the automatic clustering of mature silkworms is basically completed. 20 ml of clustering agent is used for each silkworm, and the clustering agent solution is prepared according to the weight ratio of clustering agent to water of 1:220-280. The clustering agent solution at this ratio has no effect on the quality of cocooning of mature silkworms and can achieve the purpose of driving away wandering silkworms.

[0014] As a preferred technical solution, in step (5), after spraying the clustering agent solution, the silkworm excrement on the grid cluster is cleaned to avoid contamination of the cocoons; and at night, a light can be turned on above the cluster rack to drive the mature silkworms to quickly enter the grid by taking advantage of their backlight orientation.

[0015] As a preferred technical solution, the amount of ecdysone used is 2 ml of ecdysone injection dissolved in 1.8-2.2 kg of water for each silkworm egg, and evenly sprayed on 15-20 kg of fresh mulberry leaves. The silkworms are allowed to eat them all at once, which can make the silkworms mature evenly and reduce the number of wandering silkworms.

[0016] As a preferred technical solution, when using silkworm beds to raise silkworms, the length of the square clusters is wider than the width of the silkworm beds, so that mature silkworms can be easily clustered.

[0017] By adopting the above technical scheme, an automatic clustering method for wandering silkworms without picking up is realized, through the steps of adding molting hormone, concentrating silkworm heads, placing cluster racks, clustering, driving away wandering silkworms once and continuing to drive away wandering silkworms, the silkworms are automatically clustered and enter the cells on the square cluster, avoiding the phenomenon of two silkworms in one cell and wandering silkworms on the clustering rack, eliminating double palace cocoons and yellow spot cocoons, and there is no need to turn over the clusters, simple operation, low labor intensity, and less labor, which is conducive to the large-scale development of silkworm production.

[0037] Embodiment 3

[0038] An automatic clustering method for silkworms without picking up wandering silkworms comprises the following steps:

[0039] (1) Add molting hormone to the silkworms. When about 5-6% of the silkworms are mature, pick up the early-maturing silkworms and then feed them on the silkworm bed at a rate of 250g / m 2 Sprinkle fresh lime powder, then spread silkworm nets to feed mulberry, spray molting hormone on the mulberry leaves, the dosage of molting hormone is 2ml molting hormone injection dissolved in 2.2kg water for each silkworm seed, spray evenly on 20kg fresh mulberry leaves, let the silkworms eat all at once;

[0040] (2) Collect the silkworm heads, add molting hormone, and then feed each silkworm 25m 2 The silkworm heads are concentrated according to the standard, and the silkworm seats are arranged so that the silkworms are evenly distributed on the seats;

[0041] (3) Place the cluster rack and fix the upper cluster rack above the silkworm seat behind the silkworm head. Then, hang the square clusters evenly on the upper cluster rack according to the ratio of 245-250 square clusters per silkworm and 162 grids per square cluster. The lower edge of the square clusters should touch the silkworm body. The square clusters should be inclined at an angle of 80 degrees to the ground and the distance between the square clusters should be 12 cm.

[0042] (4) The mature silkworms on the silkworm seat automatically crawl into the holes on the square cluster to go up to the cluster;

[0043] (5) Driving away the wandering silkworms at one time, when they are on the cluster, as the silkworms gradually mature, the mature silkworms also gradually climb up the cluster and climb onto the grid cluster. The mature silkworms that first climb onto the grid cluster enter the holes on the upper part of the grid cluster. If there are wandering silkworms crawling on the upper cluster rack, spray the wandering silkworms on the upper cluster rack with a crawling agent solution to drive the wandering silkworms on the upper cluster rack down to the grid cluster for climbing up. At this time, the upper part of the grid cluster can also be sprayed with a crawling agent solution. After spraying the crawling agent solution, clean the silkworm feces on the grid cluster. At night, turn on the light above the upper cluster rack;

[0044] (6) Continue to drive away the wandering silkworms, and the mature silkworms that subsequently climb onto the grid cluster enter the cells at the bottom of the grid cluster. After 14 hours of waiting for the mature silkworms to climb onto the cluster, if there are wandering silkworms crawling onto the upper cluster rack, spray the wandering silkworms on the upper cluster rack with the climbing agent solution again to drive the wandering silkworms down to the grid cluster, so that the silkworms can climb onto the cluster automatically;

[0045] In steps (5) and (6), the clumping agent solution is prepared by using 20 ml of clumping agent for each silkworm and the weight ratio of clumping agent to water is 1:280.

[0046] The present invention makes full use of the physiological characteristics of mature silkworms that like to crawl upwards, so that the mature silkworms can smoothly enter the upper cells of the square cluster. At the same time, the smell of the climbing agent not only drives the wandering silkworms back to the square cluster, avoiding picking up wandering silkworms, and the operation is simple. A small amount of smell of the climbing agent on the upper part of the square cluster allows the subsequent mature silkworms to smoothly enter the lower cells of the square cluster, and the mature silkworms can be automatically clustered without turning the cluster, with low labor intensity and less labor. According to statistics, at present, because the mature silkworms need to turn the cluster and pick up wandering silkworms, an average of 2.5 workers are required for a single silkworm to cluster, while the above three embodiments of the present invention do not require a large number of workers to catch the mature silkworms or pick up wandering silkworms when the mature silkworms are clustered. After statistics, only 0.67 workers are required for a single silkworm on average, which greatly reduces the labor and has low labor intensity. It is suitable for the large-scale development of mulberry silkworm production, and because there is no need to pick up wandering silkworms, damage to the mature silkworms is avoided, and the quality of cocooning is improved.

[0047] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
