摘　　要：黑龙江是我国大麻主要产区,为解决生产中滥施化肥、过量用肥现象,本文通过不同N、P2O5、K2O施用条件下对大麻原茎产量影响的研究,得出大麻对N、P2O5、K2O最佳施用剂量。试验得出:大麻生产最佳施用N、P2O5、K2O剂量为90kg/hm2、100kg/hm2、80kg/hm2。Heilongjiang province is one of the main hemp production areas in our country. This research result could solve the problems of fertilizing too much and chemical fertilizers wrongly in production. Different combinaitons of N、P2O5 and K2O were experimented and fertilized in hemp fields, and the hemp stem yields were examined. According to the hemp stem yields, we eould get the best does of N、P2P5 and K2O.The result showed that the optimal combination was 90kg/hm2 of N, 100 kg/hm2 of P205 and 80 kg/hm2 of K20 respectively.
