Abstract

The invention relates to the technical field of silkworm breed cultivation, in particular to a method for breeding a high-quality high-yield silkworm breed suitable for industrial breeding. The method includes: adopting a single moth area breeding method, a gradual improving and selecting technique and a molecular marker technology to acquire moth areas and individual breeds which are stabile in hereditary and good in artificial feed eating; adopting a China-Japan series breeder seed genetic complement principle and a molecular marker genetic polymorphism and genetic difference analysis technique to generate a good hybridized combination generation by mating and acquire the high-quality high-yield silkworm breed according with industrial production; adjusting breeding temperature, feed amount, feed shape and breeding facility and adopting a silkworm disease prevention technique unique in pertinence and a temperature and humidity remote controlling technique to systematically set up an artificially-fed silkworm breeding technology and a hybridized combination generation artificial feeding and industrial feeding technology. The good breed which is high in feed consumption and suitable for industrial breeding is selected by means of the hybridization technique, orderliness and robustness in development are promoted, diseases and environmental hazards are reduced, and safety in silkworm breeding is guaranteed.

Description

Be applicable to the high-quality of industrial aquaculture, the selection of high yield silkworm kind

Technical field:

The present invention relates to silkworm egg and cultivate technical field, be specifically related to be applicable to the high-quality of industrial aquaculture, the selection of high yield silkworm kind.

Background technology:

Since the nineties in 20th century, there is significant variation in the national conditions of China and sericulture technology, and having brought for applying of artificial diet rearing technology may.First, from national conditions, the national economy of China had obtained and had developed rapidly in recent years, met or exceeded the level in Japanese the eighties mid-term in the development degree of some advanced regional rural economys, along with the adjustment of the industrial structure and developing rapidly of township industry and two high excellent agriculturals, the price of labour power rises steadily, environmental pollution, pebrine break out etc. also to sericulture particularly the silkworm industry of developed regions caused enormous impact.And traditional silkworm and mulberry production technology, operation is loaded down with trivial details, and manual labor is heavy, and scale of operation is little, and benefit is not high, the requirement that can not adapt to the situation far away.

Artificial diet rearing technology itself yet exists some problem to be solved: the one, and feed cost is high, has exceeded silkworm raiser's ability to shoulder economically; The 2nd, feed corruption apt to deteriorate, to sericulture facility and requirement for environmental conditions harshness, and the sericulture condition in China rural area is simpler and cruder, is difficult to reach requirement; The 3rd, China there is no practical artificial diet rearing specific breed, and current race is all not ideal enough to the ingesting property of artificial feed, causes silkworm astogeny uneven, has affected the raising of Cocoon quantity and quality and sericulture work efficiency; The 4th, raising method is too complicated, and technical difficulty is large, is difficult for being grasped by silkworm raiser; The 5th, supporting special sericulture facility and feed production supply system, the modulator approach of feed also needs to be improved simplification.Because thereby above various reasons has limited silk cocoon applying on producing, realize silk cocoon industrial aquaculture and seem particularly important.

Summary of the invention:

The object of this invention is to provide and be applicable to the high-quality of industrial aquaculture, the selection of high yield silkworm kind, it passes through hybridization technique, select the improved seeds that food ration is applicable to greatly industrial aquaculture, break through traditional planting mulberry and breeding silkworm pattern, realizing larva artificial fodder batch production breeds silkworms, raise temp. and humidity and take remote auto control, promote to grow neat stalwartness, reduce morbidity and environmental hazard, ensure sericulture safety.

In order to solve the existing problem of background technology, the present invention is by the following technical solutions: its breeding method is:

Step 1: divide zones of different, the moth of different cultivars is carried out to subregion and cultivate raising;

Step 2: by the screening technique successively improving, simultaneously binding molecule labeling technique, the artificial feed that filter out genetic stability ingest Xing Haoe district and individual breeding;

Step 3: Japanese original seed genetic complement principle and molecular labeling genetic polymorphism and hereditary difference analytical technology thereof in utilization, by Japanese excellent strain in good the ingesting property of artificial feed of acquisition, adopt diallel cross technology, assembly first generation cross-fertilize seed, obtains and meets the good quality and high output artificial feed kind that industrialization is produced;

Step 4: by adjust raising temperature, feed to amount, diet shape, raise arrange, the flacherie of specific aim uniqueness prevents technology and temp. and humidity remote control technology, carry out artificial feed silkworm egg reproduction technology and the factory farming of first generation cross-fertilize seed artificial feed of system and cultivate.

The present invention has following beneficial effect: it passes through hybridization technique, select the improved seeds that food ration is applicable to greatly industrial aquaculture, break through traditional planting mulberry and breeding silkworm pattern, realizing larva artificial fodder batch production breeds silkworms, raise temp. and humidity and take remote auto control, promote to grow neat stalwartness, reduce morbidity and environmental hazard, ensure sericulture safety.

Embodiment:

This embodiment is by the following technical solutions: its breeding method is:

Step 1: divide zones of different, the moth of different cultivars is carried out to subregion and cultivate raising;

Step 2: by the screening technique successively improving, simultaneously binding molecule labeling technique, the artificial feed that filter out genetic stability ingest Xing Haoe district and individual breeding;

Step 3: Japanese original seed genetic complement principle and molecular labeling genetic polymorphism and hereditary difference analytical technology thereof in utilization, by Japanese excellent strain in good the ingesting property of artificial feed of acquisition, adopt diallel cross technology, assembly first generation cross-fertilize seed, obtains and meets the good quality and high output artificial feed kind that industrialization is produced;

Step 4: by adjust raising temperature, feed to amount, diet shape, raise arrange, the flacherie of specific aim uniqueness prevents technology and temp. and humidity remote control technology, carry out artificial feed silkworm egg reproduction technology and the factory farming of first generation cross-fertilize seed artificial feed of system and cultivate.

This embodiment has following beneficial effect: it passes through hybridization technique, select the improved seeds that food ration is applicable to greatly industrial aquaculture, break through traditional planting mulberry and breeding silkworm pattern, realizing larva artificial fodder batch production breeds silkworms, raise temp. and humidity and take remote auto control, promote to grow neat stalwartness, reduce morbidity and environmental hazard, ensure sericulture safety.
