Description

TECHNICAL FIELD

[0001] The application provides a breeding method of tussah silkworm, and particularly relates to a yield-increasing breeding method of tussah silkworm based on biological habit protection of ecological environment. BACKGROUND

[0002] The conventional breeding method of tussah silkworm is that the whole breeding base is divided into multiple small plots, and a multi-batch year-by-year rotation mode is implemented, each plot is used for breeding every year, and silkworm rearing is not stopped for rest. The conventional breeding method of tussah silkworm has many disadvantages. First, after the breeding base is divided into multiple small plots, it is not conducive to the management and investment of modern technical equipment. Second, the updated plot does not stop silkworm rearing for rest, and directly carries out a new round of silkworm rearing, which not only fails to achieve the purpose of updating and preventing harm, but also seriously damages the ecological environment. When preventing and eliminating harm, the breeding base can only use drugs with silkworms and staggered drugs, which not only harms silkworms and leaves, but also affects the yield of tussah silkworm due to the unsatisfactory effect of preventing and eliminating harm. In addition, the use of drugs for many years leads to serious pollution, which is not conducive to the development of economic vegetation and causes a large amount of waste of valuable resources. SUMMARY

[0003] In view of the problems in the prior art, the application provides a yield-increasing breeding method of tussah silkworm based on biological habit protection of ecological environment, which solves the problems of low yield and damage to the ecological environment in the prior art.

[0004] The technical scheme of the application comprises the following steps:

[0005] Step 1, the whole breeding base is stopped for rest for one year according to a fixed breeding period;

[0006] Step 2, the breeding base stopped for rest is divided into multiple blocks according to the growth of trees and the number of collected silkworms, each block contains 7-15 trees, one tree with moderate growth is selected from the largest tree in each block and is marked, and then all the remaining trees without marks are cut at a distance of 3-6 cm from the ground to form a three-dimensional multi-layer breeding vegetation mode;

[0007] Step 3, the reserved trees are first strengthened, and then the weak and dead branches are removed, and when the new trees grow, the number of reserved trees is determined according to the space conditions of adjacent plots, and the number of reserved trees is gradually increased to 20-50 in each block in the next rotation, and the above steps are repeated.

[0008] Step 4, during the period of high occurrence of leaf-eating insects, the period of high occurrence of leaf-eating insects and the period of high occurrence of silkworm diseases, the cultivation base of the three-dimensional complex cultivation vegetation mode is treated with drugs to kill pests;

[0009] Step 5, the cultivation base of the cultivation base is stopped for one year, and the ants are placed on the upper layer of the high tree vegetation, and when the ants are developed to the second to third hibernation, they are moved to the surrounding new tree vegetation, and the amount of leaf-eating silkworms is kept low, and the amount of new leaf-eating silkworms is kept low, and then the traditional cultivation of tussah silkworms is carried out to the cocoon.

[0015] The beneficial effects of the present application are:

[0016] The present application updates the traditional industry base in a fixed cycle at one time, fully utilizes resources, and transforms the traditional single-layer cultivation base into a three-dimensional complex cultivation vegetation base. The base is stopped for one year after updating, and the base is completely killed during the maintenance period, which improves the yield of tussah silkworms and updates the pests. DETAILED DESCRIPTION

[0017] In order to deepen the understanding of the present application, the present application will be further described in the following examples, which are only used to explain the present application and do not constitute a limitation on the scope of protection of the present application.

[0018] Examples

[0019] The present application is a kind of based on biological habits to protect ecological environment's increasing yield silkworm breeding method, including the following steps:

[0020] Step 1, the whole breeding base is stopped silkworm rearing and rested for one year according to a fixed breeding cycle; the fixed breeding cycle is 6 years.

[0021] Step 2, the breeding base stopped silkworm rearing and rested is divided into multiple blocks according to the growth of trees and the number of collected ants, each block contains 7-15 trees, one tree with medium growth is selected from the largest tree in each block, and obvious marks are made on the tree, then all the remaining trees without marks are cut off at a distance of 3-6 cm from the ground, forming a three-dimensional multi-layer breeding vegetation mode;

[0022] Step 3, the reserved trees are first thinned and strengthened, then the weak and dead branches are removed, when the new trees grow, the number of reserved trees is determined according to the space conditions of adjacent land types, the number of reserved trees is between 5-8 per tree, and the total number of trees in each block is between 20-50, until the next breeding cycle, the above steps are repeated.

[0023] Step 4, during the high incidence period of leaf-eating insects, the high incidence period of silkworm-eating insects and the high incidence period of silkworm diseases, the breeding base of the three-dimensional multi-layer breeding vegetation mode is treated with drugs to kill pests.

[0024] Step 5, after the breeding base stopped silkworm rearing and rested for one year, the collected ants are placed on the upper layer of high tree vegetation, when the ants develop to the second to third hibernation, they are moved to the surrounding newly grown tree vegetation, keeping each tree with silkworms, and the amount of silkworms eating leaves is less than the amount of new leaves of trees, then the traditional method of breeding tussah silkworms is used until cocooning is completed.

[0025] The principle and innovation of the application are as follows:

[0026] The silkworm base is renewed and disinfected, and it is far from enough to remove the contaminated trees according to the traditional method. The biggest pathogen carrier in the base is the ground. If silkworms are directly bred, under the action of the flow carriers such as people, silkworms, wind, rain and insects, the bottom leaves of the new trees are seriously contaminated again, and the virus will be hosted in the body after the silkworms eat, and cannot be immediately manifested. Before the silkworms enter the old sleep period, the body is acidic and inhibits the virus and resists the disease. When the silkworms enter the old sleep period after being replaced with trees, the body is alkaline, which accelerates the multiplication and spread of the virus, reflects the disease state, and aggravates the spread and harm. This phenomenon also leads to the misjudgment of the specific harmful trees by the breeders. Therefore, only the rest allows the virus to lose the host, and under the action of ultraviolet rays in the wild, the virus is rapidly eliminated. The bottom leaves of the new trees are less close to the ground and are easy to handle, so as to achieve the purpose of updating and disinfecting. Even if the silkworm disease is not serious before the base is updated, the base will be seriously exposed due to the need for clearing the field, the loss of leaves caused by the silkworms eating leaves and the silkworms moving, and the ecological environment will be greatly reduced. The trees will be seriously dead next year, and the leaf quality and quantity will be greatly reduced. In addition, the breeding operation can cause the silkworm body damage and recontaminate the base, which is not worth the loss. Therefore, the base rest of the present application can thoroughly prevent diseases and pests, and has an irreplaceable role. According to the natural law that only under the condition of meeting and coexistence between organisms can diseases and pests occur, the best effect can be achieved by thoroughly killing pests with drugs during the high incidence period of leaf-eating insects and the high incidence period of silkworm-eating insects and the high incidence period of silkworm diseases. Because the tussah silkworm is bred in the wild, the natural enemies and diseases are serious, and killing and preventing pests is an important link in the industry. The traditional operation mode is to use drugs during the silkworm breeding period. In addition, the silkworms are placed in batches in the whole base, and even if the same batch of silkworms is affected by natural conditions, the development is not uniform, and the harmful natural enemies are also in the same condition. In addition, the effect of the used drugs is poor due to the limitation of weather, equipment and other factors, but the negative effect is great.

[0027] The present application can promote the spring cocoon breeding of the tussah silkworm industry, increase the yield of the autumn silkworm breeding, improve the ecological environment, and improve the grade of food and obtain the income of concurrent operation.

[0028] The present application can promote the spring cocoon breeding of the tussah silkworm industry, increase the yield of the autumn silkworm breeding, improve the ecological environment, and improve the grade of food and obtain the income of concurrent operation.

[0029] Let: total leaf amount W, total consumed leaf amount Q, leaf amount value A through environmental improvement, leaf amount value B through thinning pruning, leaf amount value C through regulation of consumption speed, and leaf amount value D through reasonable management. Then W = A + B + C + D, let leaf amount E for good cocoon, leaf amount F for poor cocoon, leaf amount G for idle silkworm, leaf amount L for pest, leaf amount S for loss due to silkworm moving, and leaf amount T for remaining. Then Q = E + F + G + L + S + T, because W = Q, A + B + C + D = E + F + G + L + S + T, let total amount of good cocoon m, and leaf amount n for single cocoon,

[0030] Then

[0031] In the above formula, n is regarded as a constant value, T value is proportional to A value, and T value does not need to be reduced. Therefore, as long as A, B, C, and D values are increased and F, G, L, and S values are reduced, E value can be increased, and m value is also increased to achieve ideal harvest. The new mode operation can increase A, B, C, and D values, and compared with the traditional method, the new mode operation is to implement new method and update, base rest has benefit tree growth, A value is increased, useless tree is removed, nutrients are concentrated in the reserved tree, B value is increased, silkworms are placed on the upper layer of high trees, when the young silkworms are close to three molting of small trees, they are immediately moved to the reserved new mound around, the mound is kept with silkworms, and the consumption speed of silkworms is matched with the new leaf amount of trees, when the consumption peak of silkworms arrives, the tree leaves are close to retirement, C value is necessarily increased, the rest period has been completely treated with drugs to kill pests, and the drugs are not used during silkworm breeding, which promotes D value to increase. The innovation mode can reduce F, G, L, and S values (relative to the traditional method), the base is updated and rested during the year, and the pests are killed by drugs multiple times, which not only cuts off the transmission route of the disease source, but also makes the remaining viruses quickly die in the wild because of the lack of hosts, and the high trees are greatly reduced, the occurrence of diseases and pests is greatly reduced, F, G, and L values are significantly reduced to be negligible. Because the silkworms are first collected on the high trees of the vegetation in the new method, when the tussah silkworms climb down from the high place during the second molting, the small trees below are not eaten, and silkworm moving and pruning are not needed, which can greatly reduce the loss of leaf amount S value. It is concluded that the innovation mode is feasible for the development of tussah silkworm industry.
