2007-2011在浙江省遂昌县开展了单季稻稻田福寿螺调查监测,研究了单季稻稻田福寿螺预测预报技术和防治指标。结果表明:预测浙南山区单季稻稻田福寿螺发生程度关键是越冬后福寿螺田间基数,建立了预测模型 Y =0.2045+0.4447X ,吻合率92.9%。手插移栽单季稻产量损失率(Y 1)与越冬后福寿螺田间基数(X 1)的关系模型为 Y 1=1.4661+0.4169X 1,直播单季稻产量损失率(Y 2)与越冬后福寿螺田间基数(X 4)的关系模型为 Y 2=3.7914X 4-1.6613。在现有生产条件下,经济允许水平(EIL )为2.1%~2.8%。制定了手插单季稻福寿螺防治指标为1.5~3.2头/m2,直播单季稻防治指标为1.0~1.2头/m2。
2007-2011在浙江省遂昌縣開展瞭單季稻稻田福壽螺調查鑑測,研究瞭單季稻稻田福壽螺預測預報技術和防治指標。結果錶明:預測浙南山區單季稻稻田福壽螺髮生程度關鍵是越鼕後福壽螺田間基數,建立瞭預測模型 Y =0.2045+0.4447X ,吻閤率92.9%。手插移栽單季稻產量損失率(Y 1)與越鼕後福壽螺田間基數(X 1)的關繫模型為 Y 1=1.4661+0.4169X 1,直播單季稻產量損失率(Y 2)與越鼕後福壽螺田間基數(X 4)的關繫模型為 Y 2=3.7914X 4-1.6613。在現有生產條件下,經濟允許水平(EIL )為2.1%~2.8%。製定瞭手插單季稻福壽螺防治指標為1.5~3.2頭/m2,直播單季稻防治指標為1.0~1.2頭/m2。

Investigation and monitoring of Pomacea canaliculata in single cropping late rice were carried out at Suichang County,Zhejiang,2007 to 2011 ,and the forecast technology and control index of Pomacea canaliculata were studied.The results showed that the key of forecasting the threat of Pomacea canaliculata in single cropping late rice in southern Zhejiang mountain area is the field cardinal number of overwintering Pomacea canaliculata .The forecast model was set up as Y =0.2045 +0.4447X ,with coincidence rate 92.9%.The relation of the loss rate of hand planting single cropping rice(Y 1 )and the field cardinal number of overwintering Pomacea canaliculata (X 1 )was Y 1 = 1.4661 +0.4169X 1 ,and the relation of the loss rate of direct-seed single cropping rice (Y 2 )and the field cardinal number of overwintering Pomacea canaliculata (X 4 )was Y 2 =3.7914X 4 - 1 .6613,and the economic injury level(EIL )was 2.1 % -2.8%.The control index of Pomacea canaliculata in hand planting single cropping rice was 1 .5 -3.2/m2 ,and the control index of Pomacea canaliculata in direct-seed single cropping rice was 1 .0-1 .2/m2 .
