Abstract

The invention relates to agriculture and can be used in the cultivation of silkworm. The purpose of the invention is to increase the productivity of the silkworm. After completion of storage 10–30 days prior to the start of incubation, the greens are removed from the refrigerator and 3–5 days after adaptation, at 18–25 ° C, they are washed in 0.05–0.25% aqueous solution of 10-demethoxy-10- N-β-hydroxyethylamine colchamine hydrochloride. In this solution, the greenery is incubated for 1 to 2 hours, stirring occasionally. 1 hp f-ly, 1 tab.

The invention relates to agriculture, in particular to the breeding of silkworm.

The purpose of the invention is to increase the productivity of the silkworm.

Example. According to the known technology of repeated (summer, autumn) fertilization of the mulberry silkworm and grenade after storage, 10-30 days before the start of incubation, is removed from the refrigerator and 3-5 days later after adaptation at 18-25 ° C and air humidity 70% is subjected to water washing with the same temperature to remove poor grains.

With the proposed method, the process of washing the grenes is combined with the treatment with the drug Yu-dezmethoxy-Yu-L-p-hydroxyethylamine colchamine hydrochloride (colholamine), while the green is soaked in a 0.05-0.25% aqueous solution of the drug. For processing, 5–10 l containers are used in which the prepared aqueous solutions of the preparation are poured and the grenade is immersed in them per 1 kg of grenes 3 l of solution. Kolholamine solution can be prepared one day before use or immediately before use. In this solution, the sock is kept for 1-2 h, stirring every 0.5 h.

After the indicated time has elapsed, the solution of the colcholamine is drained and the green is laid out with a layer of 0.5 cm to dry on a sheet or on filter paper. Dry at 18–25 ° C and 70% relative humidity for 8–10 hours. After drying, the grains are collected and incubated.

The table shows data on the effect on the tetrahybrid 3 of the mulberry silkworm and its washing with colholamine, as well as for comparison with the “Urutas and water treatment as a control experiment.

The use of the preparation Kolholina for the treatment of the mulberry silk prena during the preincubation period provides an increase in the revival of the grenes by 13.48% and the viability of the caterpillars of the autumn high.

feeding by 5.66%, the yield of cocoons from 1 box of hen increases by 8.73 kg (26.44%) compared with the control and by 6.56 kg (18.65%) compared with the treatment with the preparation “Urutas.

Claims (2)
