Method for making eggs on cards through silkworm loose eggs

Abstract

The invention discloses a method for making eggs on cards through silkworm loose eggs. According to the method, kraft paper is evenly coated with adhesive with terpene resin being the main component, and then a layer of protecting film covers the kraft paper to form a special kind of egg raising paper; when the eggs on the cards are made, first, the protecting film is torn off, then the silkworm loose eggs subjected to washing and disinfecting evenly adhere to the adhesive layer of the egg raising paper, and dry fine sand is mixed with dry muscardine-preventing powder so that the small gaps between the silkworm eggs can be filled with the mixture, and the eggs on the cards can be obtained. The method is free of toxic and side effects on the silkworm eggs, easy and convenient to operate and good in effect, the egg faces of the obtained eggs on the cards are neat and attractive, the number of egg granules is large, hatching is neat, and by wide application of the method, silkworm egg exchange is facilitated, and the loose eggs are easily and widely applied in the south.

Description

technical field [0001] The invention belongs to the field of silkworm seed production, and in particular relates to a method for making flat seed by using loose silkworm eggs. Background technique [0002] Silkworm eggs are the most basic means of production for sericulture. At present, the country produces more than 12 million pieces (boxes) of the first generation of silkworm hybrids every year. Due to differences in climate, region and production customs, the first-generation hybrids of silkworm species across the country are divided into two production types: loose egg species and flat species. The loose egg species is that after the silkworm lays the silkworm eggs on the carrier (cloth, continuous paper), the silkworm eggs are manually washed, and then weighed and packed into the box. The silkworm eggs are in the form of loose grains. Loose egg species are generally produced and used in provinces other than South China (Guangdong, Guangxi); One is produced and applie...

Problems solved by technology

[0003] In the 1990s, Sichuan Province successfully developed a method for making refined flat-attached silkworm eggs (patent No. 94111804.5 published on 1995-12-27). Spread it on the silkworm paper coated with SWS-93 adhesive to make the silkworm eggs attach to the silkworm paper to form flat attached seeds, and then cover the protective paper to prevent the silkworm eggs from falling off. The number of eggs is small, the egg surface is poor, and it is easy to fall off. The products formed are quite different from the flat seed types used in subtropical silkworm areas, and they are not practical.
