Abstract: The Spring broad bean’s time of sowing and density in He Xi cold’s irrigated area were studied by simulated field plot experiment .The results showed that the suitable time of sowing was 25March~5April,the suitable dencity was 27-30 ten thousand shot per hm2.The majon holding hundred kernd weiht，pods per plant ， shots per plant and raised the single pland of productivity were key to attaining high output of spring broad bean，within the time of sowing and density.
