不同栽培措施对元胡产量的影响.

In order to improve the key cultivation techniques of Corydalis yanhusuo W. T. Wang in Fujian Province, through more than 3 years of field experiments, the effects of the key cultivation techniques including the amount of seed stem, di任erent storage conditions of seed stem, scientific fertilization and light conditions on the yield of Corydalis yanhusuo W. T. Wang were studied. The results showed that the key technical parameters for the cultivation of Corydalis yanhusuo W. T. Wang were as follows: the dosage of seed stem of Corydalis yanhusuo W. T. Wang was 600 -- 750 g • hm-2. The optimal storage conditions of seed stem were under the cold and dry environment such as the mountain cellar. The fertilization conditions were 15 000 kg • hm-2 of decomposed sheep manure and 750 kg • hm-2 of calcium, magnesium and phosphorus as base fertilizer, 125 kg • hm-2 of nitrogen fertilizer, 75 kg • hm-2 of phosphorus fertilizer and 180 kg • hm-2 of potash fertilizer at the seedling stage under the full-sun lighting condition. Then, the maximum yield of Corydalis yanhusuo W. T. Wang could reach 6 144 kg • hm-2. [ABSTRACT FROM AUTHOR]
