Title: Effects of Cover and Fertilizer Application on the Growth and Development、Dry Matter Accumulation and the Economic Benefit of Winter Wheat in Hilly and Arid Areas
Abstract: Effects of mulching and fertilizer application on the growth and development and dry matter accumulation of winter wheat were carried out in jiaodong area during 1998~2000. Results showed that: mulching and fertilizer application can accelerate the growth and development and dry matter accumulation and improve the yield of winter wheat.organic fertilizer application and cover can improve the radicel, tillering nodes and height. The combination of oganic fertilizer(22500kg/hm2),chemical fertilizer(NH4HCO3: 990kg/hm2, Ca(H2PO4)2.H2O: 815kg/hm2,KCl: 228kg/hm2),and plastic mulching or straw mulching has the highest accumlation of dry matter? yield and the economic benifit.But the yield difference between plastic mulching and straw mulching isn't distinct.Considering the economic benifit,we have come to the conclusion that the technique of organic-fertilizing and chemical fertilizer application?straw-mulching is a economic and effective step for high-yield and water-saveing for wheat in hilly and arid areas.
