Studies of Mixed Forms of Nitrogen on Regulating the Formation of Grain Yield and Quality of Wheat (Triticum Aestivum L.) Cultivars with Specialized End-uses
Improving grain yield and quality of wheat cultivars with specialized end-uses is now one of key subjects.The nitrogen nutrition absorbed by crop is mainly NH_4~+-N and NO_3~--N which could also be metabolized meanwhile.Applying different or mixed forms of nitrogen is one of important methods to regulate the growth and development of crop.Thus, pot experiments,field experiments and sand culture experiments were completed on a sandy loam at Henan Agricultural University Experimental Station during 2004...
