A Study on Curcuma longa L.Tuber Yield Simulation Modeland Its Applicationunder Combined Agronomic Measuresfor Good-quality,High-yield and Obvious Economic Results
Abstract:A design of second orderorthogonal rotativeregresion was developedand field tested,and the tu-bermodels foryield,quality and benefit were simulated and built.The efect of agronomic measures on the tuber yield is plant density>phosphorus>sowingdate>nitrogen>potassium.There is a clear interelation efect among agronomic measures.The results of simulation experiment have shown that the optimal combination of farming practices cangreatly increase the tuber yield,quality and benefit,and is adjusted according to climate,soil,feriliz-erormanuresources,andsoon.
