Problems solved by technology

[0006] And the inventor found that, although the energy-saving and high-yield sericulture method reported in the above-mentioned open literature can effectively shorten the sericulture cycle, the three-drowning silkworm grows unstable, resulting in The quality and fineness of silkworms are not as good as old ones. When the summer temperature is high, the incidence of silkworms is high and the safety is low.

Abstract

The invention discloses a cultivation method for subtropic trimolters. The cultivation method comprises breeding, adjustment suitable for the subtropical climate and cultivation management. Breeding and adjustment suitable for the subtropical climate comprise the steps of carrying out separation after conducting filial generation by utilizing the trimolter breed of a silkworm egg station in Suji, Sichuan province and 'Gui silkworm No. 2' Bombyx mori, in the subtropical area, cultivated by the Guangxi sericulture technology popularization master station, eliminating bad individuals and interbatches, maintaining and cultivating excellent trimolter individuals and interbatches for further selection till the excellent properties are stable and the trimolters can be adapted to cultivation in the subtropical area, and silkworm eggs are continuously bred repeatedly with the excellent trimolter individuals serving as the fixed breed afterwards. The cultivation management comprises gathering of newly hatched silkworms, feeding the newly hatched silkworms, managing sleep, feeding the silkworms after the silkworms wake and conducting mounting cocooning frame management.

Description

technical field [0001] The invention relates to a silkworm breeding method, in particular to a subtropical Sanming silkworm breeding method. Background technique [0002] Mulberry silkworm (Bombyx mori) is an insect that is domesticated by moving the ancient wild silkworm indoors, and uses mulberry leaves as food. Silkworms eat leaves and grow to form cocoons on mature silkworms. During the whole growth and development process, it has its own regularity. [0003] The silkworm and the external environment are a unified and inseparable whole. The growth and development of silkworms are directly related to environmental conditions such as mulberry leaves, temperature, humidity, and air. The general silkworm breeding cycle is 25 days to 30 days, and the fifth instar silkworm spins silk and cocoons. Silkworms breed with eggs, and new organisms are formed inside the eggs. The larvae that form inside the egg hatch by biting the eggshell. The larvae that have just emerged from t...
