- W2374014771 abstract "Field plastic-mulched wheat trials were conducted by using the regression design of orthogonal rotation in terrane land in Yanan City.By means of establishing mathematical models,this paper analysed inter-reaction between wheat yield and the fertilizer input rate (including:N,P 2O 5,manure).The analysis shows that N rate is more effective than that of P 2O 5 and M,that is three times of the latter two factors.In order to guide the plantation of wheat,the paper also recommended the input rate of the three sorts of fertilizers to ensure that unit wheat yield could surpass 2 500 kg/hm2.The recommended rate of fertilizers is that N:261.1 kg/hm2 ,ranges in 251.8~272.5 kg/hm2,P 2O 5:125.1 kg/hm2,ranges in 108.9~136.5 kg/hm2 and M:14 600 kg/hm2,12 800~16 400 kg/hm2." @default.
