Construction of facilities for industrial breeding of A. chinensis

Abstract

The facility for industrial breeding of A. chinensis is constructed, which includes four parts: greenhouse, cultivation pool, small shed and supporting facilities. The greenhouse is composed of arches, columns, tie rods, suspenders, diagonal tie rods, card slots, etc. to form a basic frame. It is equipped with doors and roll film devices, and is equipped with insect nets and sunshade nets. The greenhouse is stable, safe and practical. There is a cultivation pool built in the greenhouse to create a suitable environment for planting Neptera chinensis, which is conducive to the breeding of A. chinensis. There is a small shed built on the cultivation pond, which is used for secondary warming in winter, so as to ensure the smooth overwintering of A. chinensis. Supporting facilities such as hydropower lines, drainage ditches, field roads, protective fences and publicity signs are built to better ensure the breeding of insect sources and the safety of the base. This facility can provide a suitable growth environment for the breeding of A. chinensis. It is not affected by the external environment and seasonal changes, ensuring that this temperature-loving insect can survive winter and summer normally in the Yangtze River Basin, and grow and breed all year round. .

Description

technical field [0001] The invention relates to the field of insect breeding facilities, in particular to a construction technology for factory breeding of A. chinensis. Background technique [0002] Lotus seedlings, commonly known as water peanuts, were introduced from abroad in the 1930s. It is a perennial amphibious herb with wide adaptability, strong stress resistance, and extremely fast growth. Alternaria has become a vicious weed, widely distributed in farmland, orchards, ditches, weir ponds, lakes, rivers, and wastelands, seriously affecting agricultural production and ecological environment safety, and is listed as a key control object of alien invasive organisms by the Ministry of Agriculture . [0003] At present, the prevention and control of A. japonicus mainly uses herbicides for chemical control, but this control method not only requires a lot of manpower and material resources, but also pollutes the environment. Guangdong, Guangxi and other southern regions ...

AI Technical Summary

Problems solved by technology

[0004] Flea beetle is a natural enemy insect that eats lotus seedlings. It was introduced from abroad in the 1980s. It is a thermophilic insect that can survive the winter naturally in southern regions such as Guangdong and Guangxi, but in the Yangtze River The watershed cannot survive the winter normally due to the low temperature below 0°C in winter

In the Yangtze River Basin, the use of biological control methods for Echinochloa chinensis needs to introduce a large number of sources of D. chinensis from the south in the spring year after year. This not only requires a lot of manpower and material resources, but also has no operability in actual production, which restricts the Promotion and application of this biological control technology in the Yangtze River Basin
