The invention relates to an in-situ soil collector for a paddy field and a collection method. The in-situ soil collector comprises a long cylinder, a draining device and a soil borer, wherein the longcylinder is arranged in an up-down penetration manner, a blade which surrounds the long cylinder by one cycle is arranged at the bottom of the long cylinder, the draining device can stretch into thelong cylinder from the top and is used for discharging water out of the long cylinder, the soil borer is longer than the long cylinder, can stretch into the long cylinder from the top of the long cylinder and is used for collecting soil. The long cylinder is hammered into soil, and soil in the long cylinder is collected after water on an upper layer of the soil in the cylinder is discharged, so that the original structure of to-be-collected soil can be maintained as much as possible, and the detection value of the collected soil is increased. 种水田原位土壤采集器及采集方法，包括长筒、排水器和土钻，所述长筒上下贯通，长筒的底部为绕长筒圈的刀片，排水器可从长筒顶部伸入长筒内并可将长筒内的水排出，土
