Synchronous investigations on quality of fresh and dry cocoons of silkworm in Guangxi in 2010
摘要
Abstract
[Objective]The present experiment was aimed to study the factors affecting the quality of fiesh and dry cocoons in order to sustain the production in silkworm raising farms. [Method]The quality of fresh and dry cocoons collected from 9 silkworm raising farmers of 4 main silkworm raisiug areas viz., Laibiu, Hechi, Liuzhou and Nanuiug in (Guangxi were synchrouously investigated from second half of May to eadier Jul.,2010. [Resuht]The quantity of fresh cocoous, produced in Nanning and Hechi, weighing 500 g ranged from 279-307 cocoons. The mortality of worm cocoon produced in Nanning and Laibin was found nore than 11.0％. All fresh cocoons collected from different areas showed stiff disease of varying degrees, the occurrence of which was as highest as 12.3％. Selling of immature cocoon and injured young pupa by the raisers resulted in problems with the pollution of internal cocoon. The rank of cocoon shell rate in different areas was as follows: Nanning (21.59％) ＞Laibin ( 19.04％ ) ＞Liuzhou ( 18.37％ ) ＞Hechi ( 17.47％ ). The rank of dry cocoon quality was as follows: Nanning 1 (4A3370Ⅰ) ＞Laibin 1 (4A3251 Ⅲ) ＞Nanning 2 (4A3153Ⅱ) ＞Liuzhou 1 (4A3044Ⅱ) ＞Hechi 1 (4A2954Ⅱ).[Couclusion] The quality of fresh cocoon was mainly affected by characteristics of silkworm variety, quality of mulberry leaf, climatic conditions, followed by technology of raising silkworm and management of mount cocooning frame, while that of dry cocoonn was affected by quality of fresh cocoon, characteristics of drying equipment and drying technology, etc.关键词
