泰安地区是大麻的重点产区,尤其是莱芜大麻品质优良,驰名中外。为了建立大麻合理的施肥制度,提高大麻的产量和品质,我们于1981～1984年,以莱芜大麻产区为试验基地,对大麻吸收氮、磷、钾营养元素的特性和氮、磷、钾化肥对大麻生长发育、产量和纤维品质的影响进行了研究。材料与方法供试品种为“固始魁麻”。土壤为中壤表厚粘心洪积潮褐土。耕层含有机质平均1.166％,全氮0.078％,全磷0.095％,碱解氮115.5ppm,速效磷5.5PPm,速效钾 Tai’an is the key producing areas of marijuana, especially Laiwu high-quality cannabis, well-known at home and abroad. In order to establish a reasonable fertilization system for cannabis and improve the yield and quality of cannabis, we used the Laiwu cannabis producing area as a test base in 1981-1984 to study the characteristics of nitrogen, phosphorus and potassium nutrients and the nitrogen, phosphorus and potassium fertilizers The effects of hemp growth, yield and fiber quality were studied. Materials and methods The test varieties for the “Gu Shi Quebec.” Soil is thick sticky midsummer flood tide cinnamon soil. Tillage containing organic matter average 1.166%, 0.078% of total nitrogen, 0.095% of total phosphorus, nitrogen 115.5ppm, available phosphorus 5.5PPm, available potassium
