Abstract: Treatment with different amount of organic fertilizer as base fertilizer,the effects of organic fertilizer on the growth and physiological characters of maize(Zea mays L.) jointing stage at arid area were studied. The results showed that the plant height,stem diameter,dry matter accumulation,chlorophyll SPAD,N,P,K content and photosynthetic characteristics of maize at jointing stage showed an increasing trend with the increase of organic fertilizer application amount. When the fertilization amount of 6 750 kg/hm2,plant height,dry weight, chlorophyll SPAD,photosynthetic characteristics,N,P,the K content of growth,physiological indicators achieved the best condition,so the application of 6 750 kg/hm2 organic fertilizer as base fertilizer was the optimum fertilization in Yulin Sandy Area at jointing stage of maize growth. The experiment also showed that applying organic fertilizer in arid area could improve water production efficiency and save water source.

Key words: maize(Zea mays L.), organic fertilizer, jointing stage, growth, Yulin Sandy Area
