浅析2007年河南柞蚕单位产茧量的下滑原因

Simple Analysis of the Decrease of the Tussore Production in Henan Province in 2007

分析了2007年河南柞蚕产茧量下滑的原因,结果表明:2007年春季严重干旱和气温偏高、寄生蝇的危害、微粒子病的发生等是造成产茧量下滑的主要原因。针对上述原因,提出了提早收蚁、留桩放拐、及时移蚕、良叶饱食和加强防治柞蚕饰腹寄生蝇和微粒子病等对策。

By analyzing the reason of the decrease of the tussore production in Henan province in 2007, we find out that the severe draught, the high air temperature, the disaster of the autoecious fly, the disease of corpuscule are all the main reasons for the decrease of the tussore production in the spring of 2007. To collect the newly-hatched silkworm earlier, put some pole and crutch, move silkworm timely, use good leaves and feed well the silkworm, get rid of the disaster of the autoeeious fly and disease of corpuscule are all the countermeasure.
