文章介绍了对2013年浙江省温岭市春季设施大棚与露地蔬菜蜗牛发生情况调查,并进行比较统计分析。结果表明:浙江省温岭市大棚内的蜗牛发生早,为害严重,对两季蔬菜大棚与露地的蜗牛株为害率和蜗量两者呈极显著相关关系,2013年3月20日播种蜗牛株为害率,y=0.042 2x2-0.278 4x+0.144 2,R2=0.963 54(n=9,R20.01=0.734 79),5月12日播种,y=0.736 9x-0.904 9,R2=0.986 3(n=5,R20.01=0.834 34);3月20日播种每平方米蜗牛量,y=0.376 4x-0.093 6,R2=0.900 7(n=9,R20.01=0.734 79),5月12日播种,y=1.000 0x-0.800 0,R2=0.984 0(n=5,R20.01=0.834 34)。
The paper introduced the investigation on the occurrence of snail in spring facilities greenhouses and open vegetable fields in Wenling City, Zhejiang Province in 2013 and comparative statistical analysis. The results showed that the snails in the greenhouses of Wenling City, Zhejiang Province were earlier and more devastating. There was a significant correlation between the damage rate and the snail volume of snails in greenhouse and open field in two seasons. On March 20, 2013, snails were sown Y = 0.042 2x2-0.278 4x + 0.144 2, R2 = 0.963 54 (n = 9, R20.01 = 0.73479), seeded on May 12 y = 0.736 9x-0.904 9, R2 = 0.986 3 (n = 5, R20.01 = 0.834 34); sowing amount of snails per square meter on March 20, y = 0.376 4x-0.093 6, R2 = 0.900 7 (n = 9, R20.01 = 0.73479) Day seeding, y = 1.000 0x-0.800 0, R2 = 0.984 0 (n = 5, R20.01 = 0.834 34).
