Abstract
The invention relates to a method for breeding silkworms in four seasons. The method comprises the step of controlling two factors such as environment and mulberry leaves, wherein the environment comprises temperature, relative humidity, oxygen and illumination; the temperature during the whole-instar of the silkworms is kept between 20 DEG C and 30 DEG C; the relative humidity during the whole-instar of the silkworms is kept between 70% and 90%; the volume ratio of the oxygen in the air during the whole-instar of the silkworms is kept between 15% and 21%; the illumination during the whole-instar of the silkworms is kept as 16 hours in one day; and the mulberry leaves fed at the first instar of the silkworms are the leaves from the terminal bud to the third leaf, the mulberry leaves fed at the second instar of the silkworms are the leaves from the terminal bud to the fourth leaf, the mulberry leaves fed at the third instar of the silkworms are the leaves from the terminal bud to the fifth and sixth leaves, and the mulberry leaves fed at the fourth and fifth instars of the silkworms are the leaves growing for one month. The invention provides a method for breeding silkworms in four seasons; and the silkworms can be visited by tourists, and are convenient for scientific research.
Description
Technical field
The present invention relates to a kind of method of sericulture, relate in particular to a kind of method of four seasons sericulture.
Background technology
Silkworm claims again silkworm, one of the economic insects that cocoons that weaves silk take mulberry leaf as foodstuff.Belong to Lepidoptera, Bombycidae, formal name used at school Bombyx mori Linaeus.Silkworm originates from China, and its developmental temperature is 7～40 ℃, and raising thermophilic is 20～30 ℃, mainly is distributed in temperate zone, subtropics and torrid areas.The raising of silkworm is because of the gentle mulberry leaf affects on the growth of being bullied, and the ordinary circumstance silkworm can only be in spring and growth in autumn, and each feeding period is about 30 days.Silkworm belongs to the oligophagy insect, except happiness food mulberry leaf, also can eat dead leaf, Siberian elm leaf, duck green onion, dandelion and leaf lettuce etc., and mulberry leaf are that silkworm moves the natural material that closes most.Silkworm is complete metamorphosis, passes through all one's life on ovum, larva, pupa, four forms of adult and the diverse developmental stage on the physiological function.Wherein larval phase,, hatching is cocoond to weaving silk certainly needed 22～26 days under thermophilic degree condition, and silkworm all one's life is the lower mulberry leaf 20～25g of food approximately, generally slept and casted off a skin through four times, and to growth extremely the time, body weight approximately increases by 10,000 times.The food mulberry leaf amount in the last length of time accounts for more than 85% of its total food mulberry leaf amount.The cocoon of silkworm knot can filature, and silk is the noble fiber in the textile fabric, is the raw material of silks and satins.The pupa edible of silkworm, and with moth and silkworm faeces comprehensive utilization is arranged all, be the raw material of multiple chemical industry and medical industry.
Summary of the invention
The technical problem that solves:Can only in the shortcoming of spring and growth in autumn, the invention provides a kind of method of four seasons sericulture for silkworm.
Technical scheme:The method that a kind of four seasons breed silkworms, comprise the control to environment and two key elements of mulberry leaf, described environment comprises temperature, relative moisture, oxygen and illumination, described temperature remains on 20～30 ℃ between the full length of time of silkworm, described relative moisture remains on 70～90% between the full length of time of silkworm, described oxygen shared volume ratio in air remains on 15～21% between the full length of time of silkworm, described illumination kept one day 16 hours between the full length of time of silkworm; Described mulberry leaf silkworm first the length of time feeding under terminal bud several the 3rd, silkworm second the length of time feeding under terminal bud several the 4th, silkworm the 3rd the length of time feeding under terminal bud several the 5th, six, at fourth, fifth mulberry leaf that the length of time, feeding was grown month of silkworm.
Temperature described above remains 27～28 ℃ in first and second length of time of silkworm, remains 24～25 ℃ in third and fourth length of time of silkworm, remains 23～24 ℃ in the 5th length of time of silkworm.
Relative moisture described above remains 80～90% in first and second length of time of silkworm, remains 75～85% in third and fourth length of time of silkworm, remains 70～80% in the 5th length of time of silkworm.
Oxygen described above shared volume ratio in air remains 15～21% in first and second length of time of silkworm, remains 18～21% in third and fourth length of time of silkworm, remains 19～21% in the 5th length of time of silkworm.
Mulberry leaf described above are greenhouse growths, and keeping soil temperature is 5～10 ℃, and keeping room temperature is 20～35 ℃.
Compared with prior art, the invention provides a kind of method of four seasons sericulture, silkworm all can be grown at all seasons, improved the output of silk, also make things convenient for scientific research.
Embodiment
Embodiment 1
After silkworm egg is reclaimed, in time spread out to mend and hasten the hatching of silkworms, room temperature remains 25.5～26 ℃, does wet difference and remains 1.5～2.0 ℃, should implement the dark protection of whole day when silkworm seed is grown head pigmentation stage.In first length of time of silkworm, keeping temperature is 27～28 ℃, and relative moisture is 87～92%, and oxygen shared volume ratio in air remains 15～21%, gives silkworm feeding several the 3rd mulberry leaf under terminal bud this moment; In second length of time of silkworm, keeping temperature is 27～28 ℃, and relative moisture is 82～87%, and oxygen shared volume ratio in air remains 16～21%, gives silkworm feeding several the 4th mulberry leaf under terminal bud this moment; In the 3rd length of time of silkworm, keeping temperature is 24～25 ℃, and relative moisture is 77～82%, and oxygen shared volume ratio in air remains 18～21%, gives silkworm feeding several the 5th, six mulberry leaf under terminal bud this moment; In the 4th length of time of silkworm, keeping temperature is 24～25 ℃, and relative moisture is 72～77%, and oxygen shared volume ratio in air remains 18～21%, the mulberry leaf that grown to the silkworm feeding this moment one month; In the 5th length of time of silkworm, keeping temperature is 23～24 ℃, and relative moisture is 70～75%, and oxygen shared volume ratio in air remains 18～21%, the mulberry leaf that grown to the silkworm feeding this moment one month.
Door and window will be regularly opened in the silkworm room, gets rid of vitiated air, introduces fresh air, and silkworm rearing bed will keep dry.
Described mulberry leaf are greenhouse growths, and keeping soil temperature is 5～10 ℃, and keeping room temperature is 20～35 ℃.The mulberry leaf harvest time is after the morning, dew was done before 11 o'clock and at dusk after 5 o'clock.
The silkworm of adopting said method to raise, silkworm growth normal development is neat, and compared with the silkworm of common growth, food mulberry amount increases by 10%, digests and assimilates and accelerates 8%, and body weight increases by 7%, and the amount of weaving silk increases by 3%, and silk cocoon thickness increases 0.2mm.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
