辽宁省柞蚕供种形式主要是从种蚕产区购运大量种蚕,供生产需要。由于种茧体积大,大量调运增加了运输压力,耗费了大量资金和人力。同时,由于一家一户分散保种和制种,受技术和设备条件的限制,制出的种卵质量低,难获高产,影响了柞蚕生产的发展。 Liaoning tussah species for the supply of species mainly from the species of silkworm areas purchased a large number of species of silkworms for production needs. Due to the large volume of seed cocoon, a large number of transport to increase the transport pressure, cost a lot of money and manpower. At the same time, due to the fragmentation of seed and seed production by one household, the quality of the produced eggs is low and difficult to obtain high yield, which affects the development of tussah production due to the restriction of technical and equipment conditions.
