CN104186437A - Laid silkworm egg breeding method - Google Patents

Abstract

The invention discloses a laid silkworm egg breeding method. Silkworm female moths directly lay eggs on a nuisanceless dense polyethylene nylon net. The working efficiency of laid egg breeding is high, no hazard and damage is caused to the silkworm eggs, the subsequent operations of laid egg detachment, sieving, brine comparison, winnowing, survey and the like are facilitated, and consumed materials and the labor cost are greatly reduced.

Description

A kind of laying off eggs silkworm egg reproduction method

Technical field

The present invention relates to sericulture field, be specifically related to a kind of laying off eggs silkworm egg reproduction method.

background technology:

China silkworm raiser gets used to using the sericulture of hastening the hatching of silkworms of silk eggs, and seed station is got used to lay eggs cloth, silkworm of starching and connected a generation of producing laying off eggs on paper and mingle and kind breed.Lay eggs cloth, silkworm connects on paper and produces laying off eggs, and starching is the first operation, and except cost increases, Sizing Technology needs skilled grasp; Silkworm moth connects laying eggs on paper the cloth of laying eggs, silkworm, and silkworm moth urine pollutes ovum face, easily mouldy, affects silkworm semina and grows; Lay eggs cloth, silkworm connects the laying off eggs that produces on paper, needs seeds scraper to take off ovum, easily damages ovum face, affects silkworm semina and grows; Lay eggs cloth, silkworm connects laying off eggs on paper and to salt ratio, makes troubles during with the clean thing such as paper scrap, paste piece when de-ovum.In addition, the cloth of laying eggs, silkworm connect paper, and access times are limited, increase cost, use continuously sterilization trouble.

Summary of the invention

the invention provides a kind of laying off eggs silkworm egg reproduction method, method of the present invention has the features such as high-efficiency environment friendly cost is low.

Technical scheme of the present invention is:

A laying off eggs silkworm egg reproduction method, is characterized in that, comprises the following steps:

(1) the commercially available common water suction toilet paper of lay layer 2-3 on hard supporting plate, then on paper lay 100-120 order polyethylene nylon gauze, place the production of hybrid seeds frame of 35 * 25 * 1.5 cm on the net;

(2) according to silkworm kind egg laying amount, how many inputs can be laid eggs female moth number of 25000-30000 grain ovum in production of hybrid seeds frame, allow female moth egg, record kind name, lay eggs the date;

(3) operation of repeating step (1), (2) again, stacks repeatedly;

(4) female moth egg environment is controlled under the condition that 25 ℃ of temperature, humidity are 60% and lays eggs, give birth to ovum after 12 hours, open production of hybrid seeds frame, sweep off female moth mounted box in accordance with regulations, treat particulate inspection, go unnecessary female moth, then the flat nylon wire of lifting, lies against the silkworm seed producing on nylon wire on solid silkworm plaque, same kind, with batch being stacked together;

(5) after stable under silkworm seed color nature, by same kind with batch nylon wire and silkworm seed be placed in and the square of clear water is housed washes in ovum basin, in water, soak 1-1.5 hour, with banister brush, scrub the silkworm seed on nylon gauze, while scrubbing, water rinses de-ovum, after all coming off, remove after floating thing, pour in the drainage frame that is less than silkworm seed mesh, draining is collected laying off eggs, conventional method sieves, salt ratio, selection by winnowing, investigation, finally weighs mounted box.

the present invention compared with prior art has advantages of:

The present invention is the silkworm laying off eggs mating system of traditional first generation cross-fertilize seed of the applicable rural area sericulture traditional habit of reform, adopts and allows the female moth of silkworm directly on non-harmful density polyethylene nylon gauze, lay eggs.Laying off eggs breeding process efficiency is high, to silkworm seed nonhazardous and damage, for follow-up laying off eggs threshing, sieve, the operation such as salt ratio, selection by winnowing, investigation offers convenience, consumptive material and cost of labor significantly reduce, and are particularly suitable for rural area and breed silkworms and use.

Embodiment

A laying off eggs silkworm egg reproduction method, comprises the following steps:

(2) according to silkworm kind egg laying amount, how many inputs can be laid eggs female moth number of 28000-30000 grain ovum in production of hybrid seeds frame, allow female moth egg, record kind name, lay eggs the date;

(3) operation of repeating step (1), (2) again, stacks repeatedly;

(4) female moth egg environment is controlled under the condition that 25 ℃ of temperature, humidity are 60% and lays eggs, give birth to ovum after 12 hours, open production of hybrid seeds frame, sweep off female moth mounted box in accordance with regulations, treat particulate inspection, go unnecessary female moth, then the flat nylon wire of lifting, lies against the silkworm seed producing on nylon wire on solid silkworm plaque, same kind, with batch being stacked together;

(5) after stable under silkworm seed color nature, by same kind with batch nylon wire and silkworm seed be placed in and the square of clear water is housed washes in ovum basin, in water, soak 1 hour, with banister brush, scrub the silkworm seed on nylon gauze, while scrubbing, water rinses de-ovum, after all coming off, remove after floating thing, pour in the drainage frame that is less than silkworm seed mesh, draining is collected laying off eggs, conventional method sieves, salt ratio, selection by winnowing, investigation, finally weighs mounted box.
