在山东花生主产区调查了花生田周边不同作物、土质、花生种植方式对花生蛴螬发生的影响。结果表明,周围种植玉米、杨树和桃树的花生田,蛴螬发生量明显大于周边无此3种植物的花生田;壤土田蛴螬的发生量明显大于砂土质和黏土质田块;春花生覆膜种植较非地膜露地种植可明显减轻蛴螬发生量50%左右。在花生生产上推广春花生地膜覆盖种植,选择砂土质地,远离周边有杨树、果园、玉米田种植,均可减轻蛴螬的发生与为害。
In the peanut main producing area of Shandong Province, peanut fields around the peanut different crops, soil, peanut planting methods on peanut slugs occurrence. The results showed that in the peanut fields around which maize, poplar and peach trees were planted, the occurrence of mullet was significantly greater than that of the peanut without the three surrounding plants. The occurrence of mullet in the loamy soil was obviously higher than that of sandy soil and clay soil. More than non-plastic film planting can significantly reduce the occurrence of catfish about 50%. Poplar peanut cultivation in the promotion of plastic film mulching planting, selection of sand and soil texture, far from the surrounding poplar, orchard, corn field planting, can reduce the occurrence and damage of the mullet.
