唐山地区常年种植花生120万亩左右,总产在1.5亿公斤上下,是河北省花生重点产区。但多年来单产较低,除土质瘠薄、春季干旱、播种较晚等原因外,花生病毒病也是影响产量的重要因素。1985年病毒病发生较轻,全市发生8.2万亩,花生单产151公斤,总产1.64亿公斤,均创历史最好水平。1986年病毒病发生严重,全市发生面积79.6万亩,占花生总面积的71%,产量损失3200多万公斤;1989年病毒病中等偏重发生,总面积46万亩,产量损失约1600万公斤。
The annual peanut planting area in Tangshan is about 1.2 million mu, with a total output of 150 million kilograms. It is a key producing area of peanut in Hebei Province. However, the yield has been relatively low for many years. Except for soil infertility, spring drought and later sowing, peanut virus disease is also an important factor affecting yield. In 1985, the virus disease occurred lightly, with 82,000 mu in the city, 151 kg peanut yield, and 164 million kg total output, all of which were the best in history. In 1986, the virus disease was serious. The city had an area of 796,000 mu, accounting for 71% of the total peanut area and the loss of output was over 32 million kilograms. In 1989, the virus disease was moderately weighted with a total area of 460,000 mu and the yield loss was about 16 million kilograms.
