摘要
本文在紫胶虫培育和生产中的评价指标基础上 ,建立综合评价方法及评价公式 :(1)种胶的判断公式是E =e×p× (1-m)× (1-s) ;(2 )生产判断公式是I =(Nt+ 1) /Nt=∏(si)·p♀·F ;(3)寄主植物的判断公式是E =p× (1-m)× (1-s) ×d。采用综合评价方法能较科学地反映和评价紫胶虫的种胶。
Comprehensive methods and formulas of lac insect evaluation were proposed in this paper based on such indexes from lac insect cultivation and production.These formulas could be shown as follows: 1) E=e×p×(1-m)×(1-s) for seed lac; 2)I=(N t+1)/N t=∏(si)·p ♀·F for production and 3)E=p×(1-m)×(1-s)×d for host trees. It is more objective and reasonable for judging the insect on its seed lac, production and host tree adaptability by ways of comprehensive evaluation than that of traditional methods.
