[Effect of organic fertilizer and mineral fertilizer on the tuber yield of Curcuma longa L].
Regression method of orthogonal conic substitution with factors was employed to build up the tuber models for yield, quality and benefit. Three main measures affecting the tuber yield, quality and benefit were analyzed by these mathematical models. The effect of agronomic measures on the tuber yield is human and livestock excreta, rape cake > Ca3(PO4)2 > KCl. The optimal combination of farming practices has been obtained according to the analysis of these models.
