摘　　要：本文介绍了最新研制的新型直压式手动原状土取土钻的设计及应用。该钻由钻头、钻筒、连接座、钻杆组成。钻头非开口，相对于钻筒内外壁的“双凸”构造及在钻筒上裁一与钻头刃口直径相当的平行于轴的口。组合钻杆，继承深度标划。着重分析了该铭的结构性能。二年多的试用试验表明，该钻仅凭一人手动操作可轻松获取整个剖面继承深度原状土样和水稻土剖面原状土样、所获土样可满足野外剖面观察及室内物理、化学分析的需要，并相应提高工时工效５０余倍．该钻的广泛应用将打破土壤调查制图受大工作量、长周期、高费用支出及作物生长季节的限制，给土壤调查带来一场革命，同时也利于新土壤分类系统的快速实施及推广。The scheme and application of sampler of soil undstarbed .which is a new hand operated and verticle-pressured undisturbed soil were discribed in this paper.This sampler Consists of a sampling tip with 'double hog 'structure to either inner or outer faces,a holder,a joint base ,a open cuting whose width is the same as the inner diameter of the tip,and an assemble sampler bar with continued depth scale. The structure and the properties of the sampler are discussed mainly. Trialing use has shown in two year that it is easy to get Out wonderful profile samples with continued depth scale for both dry and wet land soils by a person. The soil samples could meet the requirements of field description and lab analysis. This sampler can reduce the time and power required for taking a pedon's continued samples to only 2 to 3 percent of old one needing.The application of this new sampler will bring out great change of soil survey which always is limited to time,labor, money developing period. It is advantage to implement and application of new soil classification.
