Factory breeding lotus grass jump straight chest flea beetle facilities construction

Abstract

The invention discloses a factory breeding lotus grass jump straight chest flea beetle facilities construction which comprises a greenhouse, a culture pond, a small plastic greenhouse and ancillary facilities, wherein the greenhouse is a basic framework composed of an arch bar, stand columns, draw bars, suspenders, diagonal draw bars and card slots, a door and a film rolling device are arranged on the basic framework, an insect proof net and sunshade net are arranged, the greenhouse is stable, safe and practical. The culture pond is arranged in the greenhouse, suitable environment is established for planting alternanthera philoxeroides is beneficial to the jump straight chest flea beetle breeding of the alternanthera philoxeroides. The small plastic greenhouse is arranged above the culture pond for increasing the temperature for the second time in winter and ensuring smooth jump straight chest flea beetle breeding of the alternanthera philoxeroides. Water and electricity lines, drainage ditch, country roads, protective fence and advertising boards are established for ensuring insect source breeding and base safety. Suitable growth environment is offered for the breeding of the alternanthera philoxeroides straight chest flea beetle without influence of external environment and seasonal change; the thermophily insects in Yangtze river basin can be ensured to overwinter and oversummer normally and to grow and breed all the 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
