A Study on on the Mathematic Models of High-yiecd, Top- quiality of Comprehensive Agricultural Measures in Wheat Production of Henan II Yield Models Analysed
Function model for output of sweet potato was set up as well. Meanwhile, sequences of model elements(N>P>K) and comprehensive agricultural measures (N=72.735 kg/hm 2, P 2O 5=96.915 kg/hm 2 and K 2O=127.995 kg/hm 2 ) for the output of optimal economic benefit were expected.
A Study on the Mathe matic Models of High-yield, Topquality of Comprehensive Agricultural Measures in Wheat Production of Henan I Models Established &Measures Optimizated
A Study on Mathematte Models of Comprehensive Farming Measures for the Cultivation of Higher Yield and Fine Quality Wheat Production in Henan III Quality Models Analysed
In this paper, through the analyzation of the mathematical model of the comprehensive farming measures designed for the cultivation of higher yield and finer quality wheat in Henan, was observed the model of effects on the wheat quality exerted by single factor and two factors by means of basal dressing of N, P2O5, topd ressing of N and different plant density
