一、试验材料 供试板栗为今年9月份采摘的新鲜板栗。有虫率14.6％,含水率46.5％。经解剖检查,栎实中的害虫绝大多数为栎实象幼虫Curculio da-vidi Fairmaire,但也有极少量的桃柱野螟Dich-ocrocis Punctifeialir Guenee。 二、试验方法 试验器材采用罗山县农业电子研究所研制的小功率高频电场种子处理机,功率1O瓦、频率为40兆赫。因该机功率太小,为提高发射电场强度,我们将机器原来的种子处理漏斗改装成平行板电容器结构;两极板面积各为2.5平
First, the test material for the test Chestnut picked in September this year, fresh chestnuts. The worm rate of 14.6%, 46.5% moisture content. After dissection, most of the pests in Quercus acutissima were Curculio da-vidi Fairmaire, but there were also a very small amount of Dich-ocrocis Punctifeialir Guenee. Second, the test method The test equipment used by the Institute of Agricultural Electronics Luoshan developed low-power high-frequency electric field seed processing machine, power 1O watts, a frequency of 40 MHz. Because the machine power is too small, in order to improve the intensity of the electric field emitted, we converted the original seed processing funnel of the machine into a parallel plate capacitor structure; the area of the two polar plates is 2.5
