Method for breeding high-quality high-yield silkworm breed suitable for industrial breeding

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

Technical field: [0001] The invention relates to the technical field of silkworm egg breeding, in particular to a breeding method for high-quality and high-yield silkworm varieties suitable for industrial farming. Background technique: [0002] Since the 1990s, my country's national conditions and sericulture technology have undergone significant changes, which has brought possibility for the popularization and application of artificial feed breeding technology. First of all, from the perspective of national conditions, my country's national economy has achieved rapid development in recent years. In some advanced areas, the rural economy has reached or even exceeded the level of Japan in the mid-1980s. And the rapid development of two high and one high-quality agriculture, rising labor prices, environmental pollution, outbreaks of particulate diseases, etc. have also caused a huge impact on sericulture, especially sericulture in developed areas. However, the traditional seri...

Problems solved by technology

However, the traditional sericulture production technology has cumbersome procedures, heavy physical labor, small scale of operation, and low efficiency, which is far from being able to meet the requirements of the situation.

[0003] There are still some problems to be solved in artificial feed breeding technology itself: first, the cost of feed is high, which is beyond the economic bearing capacity of silkworm farmers; The conditions for raising silkworms are relatively simple, and it is difficult to meet the requirements; the third is that there are no practical artificial feed breeding varieties in my country, and the current varieties are not ideal for artificial feed feeding, resulting in uneven development of silkworm colonies, which affects silkworm cocoon production and quality and breeding. The improvement of silkworm work efficiency; the fourth is that the breeding method is too complicated, the technology is difficult, and it is not easy for silkworm farmers to master; the fifth is the supporting special silkworm breeding facilities and feed production and supply system, and the feed preparation method also needs to be improved and simplified
